SUMMARY

1 Outline of the Recipient Country

(1) Territory and Nature

The Republic of the Philippines (the Philippines) is an archipelago of islands, which is

located on the Pacific Ring of Fire, and it consists of more than 7,000 islands. Its total land

area is approx. 300,000 km2, and eleven major islands, such as Luzon, Mindanao, Samar, Leyte

and Cebu, make up 96% of the total land area. The Philippines has thousands of faults, approx.

220 volcanos and over 30,000-km-long coast lines. Due to such geographical nature, the

country has been frequently affected by earthquakes, volcanic eruptions and tsunamis caused by

great earthquakes occurred in the Pacific Rim. And also, it is emphasized that most of

typhoons developed around Mariana Islands tend to reach the country.

The Philippines has a monsoon climate on the west coast and a tropical rainforest climate on

the east coast, with high temperature and humidity all year long. Excluding the alpine region

with an altitude above 1500m, the temperature does not change greatly throughout the year; an

average temperature of 26.6°C, mean maximum temperature of 28.3°C (May), and mean

minimum temperature of 25.5°C (January). And, monthly mean humidity is between 71%

(March) and 85% (September). Precipitations are different from place to place; annual rainfall

varies from less than 1,000 mm to more than 4,000 mm, since it is due to geological conditions,

monsoon, route of typhoon etc.

(2) Socioeconomic Conditions

According to the Census 2010, the population of the Philippines is approx. 94 million

(projection). 1.1 million people reside within the National Capital Region (NCR), and one

third of the total national population reside within NCR and/or in the neighbouring regions of

NCR, such as CALABARZON and Central Luzon.

The Philippines is one of the most urbanized countries in Asia. However, the gap between

the rich and poor is pretty extreme, and many people tend to migrate into the major cities for

work opportunities. According to the poverty statistics by the National Statistics Coordination

Board (NSCB), NCR has the least poverty incident of 4.0%, while CARAGA (in Mindanao) has

47.8%, Autonomous Region in Muslim Mindanao (ARMM) has 45.9%, and Bicol (in Luzon)

has 45.1%.

In the recent years, the Philippines’ economic growth remained positive, though it has been

affected by the global recession, damage of supply chain caused by the Great East Japan

Earthquake and the serious flooding in the Thailand, and the European economic decline

resulting from debt crisis. The National Statistics Office (NSO) reported the real GDP growth

ii

rates of 1.1% for 2009, 7.6% for 2010 and 3.9% for 2011 as well as the GDP per capita of 2,007

USD for 2011. On the other hand, the unemployment rate of the country continues to be 7% to

8%, and there is no obvious improvement on the job opportunities. Due to scarcity of job

opportunities in the country, approx. 10% of the total population reside in foreign countries as

Overseas Filipino Workers (OFWs).

2 Background of the Project

The countries, seriously affected by the Sumatra Earthquake and the Asian Tsunami in 2004,

are strategically addressing to improve their disaster management systems, including earthquake

monitoring and warning systems. In those countries, however, monitoring networks, data

analysis systems and warning systems for earthquake and tsunami are still under development.

Meanwhile, the Great East Japan Earthquake, occurred on 11th of March, 2011, resulted in

tremendous damages to Japan, and it reminded the international community of importance of

disaster prevention.

Since the Philippines is located on the Pacific Ring of Fire, as is for Japan, volcanic and

seismic activities are brisk, and earthquake disasters occurred frequently. It is very essential to

improve capacity for disaster mitigation and disaster response, through strengthening the

earthquake and tsunami monitoring networks, for the country that is one of the

earthquake-prone countries with a number of faults and volcanos. In addition, improvement of

drainage measures is needed for the country, due to frequent occurrence of flooding resulting

from tsunami and typhoons. Under such backgrounds, the Government of Japan (GOJ) was

requested by the Government of the Philippines (GOP) to procure equipment for improvement

of disaster risk management.

JICA had conducted basic information collection and confirmation studies on disaster risk

management mainly in countries of the Asia and Pacific-rim regions, where there are high risks

of earthquake and tsunami, from the end of September to the middle of November, 2011,

towards future assistance in the disaster risk management sector. Considering the results of the

studies, the Ministry of Foreign Affairs of Japan (MOFA) instructed JICA to conduct

“Preparatory Survey on the Project for Improvement of Equipment for Disaster Risk

Management” pursuant to “Basic Guidelines for Reconstruction in response to the Great East

Japan Earthquake (July 29, 2011, by Reconstruction Headquarters in response to the Great East

Japan Earthquake)” in order to formulate Japan’s Grant Aid projects to be implemented by the

fiscal 2011 third supplementary budget of GOJ.

3 Outline of the Survey Results and Contents of the Project

The preparatory survey team was dispatched to the Philippines from April 16 to May 21,

2012, in order to conduct the first field survey. The team had a series of discussions with the

two implementing agencies, namely Philippine Institute of Volcanology and Seismology

(PHIVOLCS) and the Department of Public Works and Highways (DPWH), as well as with the

National Economic and Development Authority (NEDA) as the responsible agency, and other

relevant agencies. The team also conducted the sites survey, survey on equipment operation

and maintenance, study on equipment planning during the first field survey. After returning to

Japan, the team continued to study and analyze the results of the field survey to make an outline

design.

As the result of such study and analysis in Japan, it was recognized necessity of the additional

field survey for further study towards preparation of the outline design for PHIVOLCS’s

elaborate equipment and systems. Meanwhile, it was judged that the outline design for DPWH

equipment would be finalized without an additional survey. This Project was formulated

aiming at disaster prevention and mitigation, under the third supplementary budget fiscal year of

2011, and it was required for the Project to contribute to improvement of disaster risk

management in the Philippines as soon as possible. Therefore, it was decided that DPWH

equipment would be procured ahead, while further survey and study continued for PHIVOLCS.

Then, the second field survey was conducted from December 2 to December 8, 2012, for

explanation of the outline design for DPWH equipment and for additional field survey for

PHIVOLCS equipment. Discussed and agreed matters during the second field survey were

confirmed on the Minutes of Discussions (M/D) signed on December 7, 2012.

After the second field survey, the team continued further study and analysis for PHIVOLCS

equipment and compiled the draft final report, and then the third field survey was conducted

from March 3 to March 8, 2013 in order to explain the outline design for PHIVOLCS

equipment in accordance with the draft final report. Discussed and agreed matters during the

third field survey were confirmed on the M/D signed on March 7, 2013.

The following tables show comparisons of the original requested items and the project

components confirmed in the M/D. Since the E/N of this Project has been signed already, it

was required to determine the scope of the Project to make fit it within the grant shown in the

E/N.

4 Implementation Schedule and Project Cost

Procurement for this Project will be conducted by the procurement agent (Japan International

Cooperation System: JICS) on behalf of the Recipient, by the method of open competitive

tender. Since there are two Implementing Agencies (PHIVOLCS, DPWH), and since the types

and implementation schedule periods for PHIVOLCS and DPWH are quite different, it was

determined to separate tender packages by the Implementing Agencies.

The total implementation period for the PHIVOLCS package is 16.5 months; 5.0 months for

tender stage and 11.5 months for procurement stage. On the other hand, the total

implementation period for the DPWH package is 14.0 months; 4.0 months for tender stage and

10.0 months for procurement stage.

The initial cost for the Project to be borne by the Philippine side is estimated as 5.71 million

Japanese Yen (2.87 million Philippine Peso).

5 Project Evaluation

(1) Relevance

1) Contribution to Disaster Prevention and Mitigation

The assistance for PHIVOLCS under this Project aims at strengthening the capacity of the

earthquake and tsunami monitoring in order to enhance the capacity of disaster mitigation and

emergency responses through provision of real-time monitoring information to the disaster

related authorities.

Regarding the earthquake monitoring network, installation of broadband strong motion

seismometers, strong motion seismometers and earthquake intensity meters will contribute to

expand the PHIVOLCS’s real-time monitoring networks, in collaboration with SATREPS.

Furthermore, it will be made possible to realize enhancement of the accuracy of analysis, swift

transmission of information on earthquakes and prediction of disaster damages, and

consequently, the capacity for initial responses after the occurrence of disasters will be

enhanced. As for the tsunami monitoring network, the first real-time tsunami monitoring

network in the Philippines will be established. The real-time data obtained with the

monitoring equipment provided by the Project will be utilized for issuance and cancellation of

warnings for tsunami.

Thus, the assistance for PHIVOLCS will not only bear direct benefits for strengthening the

capacity of disaster prevention and mitigation all across the Philippines, but also build a

foundation towards establishment of the future real-time forecasting and warning system.

x

With respect to the assistance for DPWH, it will contribute to smooth recovery and

reconstruction of the infrastructure by making it possible to drain water out of spot inundation

of roads and low-lying areas, where drainage pump facilities cannot completely drain water,

after flooding disasters occur resulting from tsunamis and typhoons.

2) Contribution to National Policies and Strategies in the Philippines

The Project is in line with the “Philippine Development Plan 2011-2016” having set a major

policy to strengthen disaster risk reduction at both national and local levels, and “The National

Disaster Risk Reduction and Management Framework (NDRRMF)” and “The National Disaster

Risk Reduction and Management Plan (NDRRMP) 2011-2028” which cover one of the thematic

areas, namely "Disaster Prevention & Mitigation", and its goals and objectives of “Enhanced

Monitoring, Forecasting and Hazard Warning” and “Disaster Rehabilitation and Recovery”.

3) Utilization of Japan’s Technologies in Disaster Risk Management Sector and Lessons

Learnt from the Great East Japan Earthquake

Japan has been providing assistance in the disaster risk management sector of the Philippines

for more than 30 years from the 1980s, and thus acquired technologies, know-how and broad

networks in the sector. Since this Project is categorized into the series of such assistance in the

disaster risk management sector of the Philippines, these acquired technologies, know-how and

broad networks can be utilized sufficiently.

Especially, regarding the technologies in the sector, they have been newly developed and

improved based on the lessons learnt from the Great East Japan Earthquake. Even in Japan,

introduction of such newly developed and/or improved equipment for disaster monitoring and

response have been promoted. One of the most remarkable cases is introduction of

Japan-made broadband strong motion seismometers, which can work for giant earthquakes,

since it was leant that the broadband seismometers went off scale when the Great East Japan

Earthquake. And, another typical example is Japan-made mobile drainage pumps whose

effectiveness was noticed in the tsunami affected areas of the Great East Japan Earthquake.

Deployment of the mobile drainage pumps to many of local governments in Japan has been

encouraged after the Great East Japan earthquake, and moreover, the equipment has greatly

accomplished great results for a severe flood disaster in Thailand in 2011.

4) Information Sharing among Japan and Neighboring Countries

Earthquake and tsunami monitoring data are not only transmitted within the Philippines, but

also shared with the following external agencies. Thus, the data obtained with the equipment

provided by the Project is also expected to contribute to enhancing the accuracy of earthquake

and tsunami monitoring, and forecasting and warning in Japan and other neighboring countries.

PHIVOLCS is a member of the Regional Working Group on Tsunami Warning and

Mitigation System for the South China Sea Region (SCS-WG) under Intergovernmental

xi

Oceanographic Commission (IOC) of UNESCO, in which Japan Meteorological Agency also

participates. For the purpose of sharing data on earthquake and tsunami in the South China

Sea region, they are aiming at development and operation of systems for earthquake monitoring,

and tsunami forecasting and warning in the region by 2016 through the establishment of a South

China Sea regional tsunami warning center and an information sharing platform. In addition,

the regional center will be connected with the Global Telecommunication System (GTS) of the

World Meteorological Organization (WMO). The information is expected to be transmitted by

the center not only in the South China Sea region but also globally.

Based on fact findings above mentioned, it is considered that relevance of the Project will be

high.

(2) Effectiveness

The following outputs are to be expected from the Project. It is considered that the Project

will be confidently effective.

1) Quantitative Outputs

Expansion and Improvement of Real-time Earthquake Monitoring Network

The real-time earthquake monitoring network will be expanded and improved through the

provision of the following equipment; 1) broadband strong motion seismometers for the

10 existing unmanned seismic stations, and 2) strong motion seismometers with real-time

monitoring function for the 36 manned stations. Consequently, monitoring of seismic

intensities, identification of epicenters and calculation of magnitudes can be conducted

swiftly, and the accuracy of analyzing earthquakes will be enhanced.

※2：340 sites = 240 sites covered by this Project + 100 sites by SATREPS.(incl. 23 sets already installed as of March 2013)

Establishment of Real-time Tsunami Monitoring Network

The real-time tsunami monitoring network will be established through the installation of

tsunami wave detectors at 19 sites, and tidal level data can be obtained in real time.

Currently, tsunami warnings that are determined based on the analysis of epicenters and

magnitudes are notified to the disaster related agencies, such as OCD, by FAX and SMS.

However, tidal level monitoring in real time by means of the equipment provided by the

Project will contribute to higher accuracy and promptness of tsunami warning and its

lifting.

Promotion of Tsunami Simulation Database Development

The establishment of the tsunami simulation database is indispensable for high accuracy

and promptness of tsunami warnings. Currently, in technical cooperation with SATREPS,

the tsunami simulation database is being developed. However, the equipment that is

currently in use does not have sufficient capacity for calculation. Thus, a PC cluster with

2) Qualitative Outputs

Strengthening of the real-time earthquake monitoring network and establishment of the

instrumental seismic intensity monitoring network will make it possible to improve the

accuracy of the analysis of earthquakes, swift transmission of earthquake information.

Consequently, the capacity for disaster mitigation and emergency responses will be

encouraged by providing real-time monitoring information and results of analysis and

warnings to the disaster related agencies, such as OCD.

Through the establishment of the first real-time tsunami monitoring network in the

Philippines, necessary data for declaring and lifting warnings can be obtained in real-time.

As is the case of earthquake monitoring, the capacity for disaster mitigation and

emergency responses will be encouraged by providing real-time monitoring information

and results of analysis and warnings the disaster related agencies, such as OCD.

It is expected that the tsunami simulation result can be improved by using of real time tide

data of each station collected through Real-time Tsunami Monitoring Network.

The implementation of this Project will not only bear direct benefits for strengthening the

capacity of disaster prevention and mitigation all across the Philippines, but also build a

foundation towards establishment of the tsunami early warning system.

The Project will contribute smooth recovery and reconstruction of not only infrastructure

but also sanitation condition of the flood area by making it possible to drain water out of

spot inundation of roads and low-lying areas, where drainage pump facilities cannot

completely drain water, after flooding disasters occur resulting from tsunamis and

typhoons.

CHAPTER 1

BACKGROUND OF THE PROJECT

1-1

Chapter 1 Background of the Project

1-1 Background and Outline of the Project

The countries, seriously affected by the Sumatra Earthquake and the Asian Tsunami in 2004,

are strategically addressing to improve their disaster management systems, including earthquake

monitoring and warning systems. In those countries, however, monitoring networks, data

analysis systems and warning systems for earthquake and tsunami are still under development.

Meanwhile, the Great East Japan Earthquake, occurred on 11th of March, 2011, resulted in

tremendous damages to Japan, and it reminded the international community of importance of

disaster prevention.

Since the Philippines is located on the Pacific Ring of Fire, as is for Japan, volcanic and

seismic activities are brisk, and earthquake disasters occurred frequently. It is very essential to

improve capacity for disaster mitigation and disaster response, through strengthening the

earthquake and tsunami monitoring networks, for the country that is one of the

earthquake-prone countries with a number of faults and volcanos. In addition, improvement of

drainage measures is needed for the country, due to frequent occurrence of flooding resulting

from tsunami and typhoons. Under such backgrounds, the Government of Japan (GOJ) was

requested by the Government of the Philippines (GOP) to procure equipment for improvement

of disaster risk management.






“Preparatory Survey on the Project for Improvement of Equipment for Disaster Risk

Management” pursuant to “Basic Guidelines for Reconstruction in response to the Great East

Japan Earthquake (July 29, 2011, by Reconstruction Headquarters in response to the Great East

Japan Earthquake)” in order to formulate Japan’s Grant Aid projects to be implemented by the

fiscal 2011 third supplementary budget of GOJ.

In implementing the Project, equipment and materials are planned to be principally procured

from Japan and/or locally. Moreover, details of procurement conditions are discussed and

determined based on the said Basic Guidelines.

The following table shows the requested items confirmed in the Minutes of Discussions

(M/D) on April 27, 2012, through discussions with the two implementing agencies, namely

Philippine Institute of Volcanology and Seismology (PHIVOLCS) and the Department of Public

Works and Highways (DPWH), as well as with the National Economic and Development

Authority (NEDA) as the responsible agency.

1-2 Natural Conditions

The Republic of the Philippines (the Philippines) is an archipelago of islands, which is

located on the Pacific Ring of Fire, and it consists of more than 7,000 islands. Its total land

area is approx. 300,000 km2, and eleven major islands, such as Luzon, Mindanao, Samar, Leyte

and Cebu, make up 96% of the total land area. The Philippines has thousands of faults, approx.

220 volcanos and over 30,000-km-long coast lines. Due to such geographical nature, the

country has been frequently affected by earthquakes, volcanic eruptions and tsunamis caused by

great earthquakes occurred in the Pacific Rim. And also, it is emphasized that most of

typhoons developed around Mariana Islands tend to reach the country.

1-3 Environmental and Social Considerations

There will be no significant negative impact on the natural environment or social issues, since

the equipment for PHIVOLCS are to be installed, with very small scale construction works, in

developed areas such as the existing seismic monitoring stations and the port areas, and since

the equipment for DPWH are items that will be carried in vehicles. An equipment plan shall

be prepared in compliance with the legislations related to building codes and standards,

regulations for communication, diesel control and other environmental restrictions.

CHAPTER 2

CONTENTS OF THE PROJECT

2-1

Chapter 2 Contents of the Project

2-1 Basic Concept of the Project

2-1-1 Overall Goal and Project Objective

In accordance with the “Philippine Development Plan 2011-2016”, which was implemented

in May 2011, the government of the Republic of the Philippines (GOP) has set a major policy to

strengthen disaster risk reduction at both national and local levels.

In the field of disaster risk management, the “Republic Act No.10121” was enacted in 2010

in order to reduce disaster risk, “The National Disaster Risk Reduction and Management

Framework (NDRRMF)” and “The National Disaster Risk Reduction and Management Plan

(NDRRMP) 2011-2028” were established in June and December 2011, respectively.

NDRMMP covers four thematic areas, namely "Disaster Prevention & Mitigation", "Disaster

Preparedness", "Disaster Response" and "Disaster Rehabilitation and Recovery" together with

goals, objectives, outputs and activities of the thematic areas.

This Project is to address the following goals and objectives of NDRRMP; “Enhanced

Monitoring, Forecasting and Hazard Warning” and “Disaster Rehabilitation and Recovery”, in

order to contribute to mitigating human suffering from disasters.

Under such GOP’s policies and strategies, this Project is aiming at (1) improving the

earthquake and tsunami monitoring capacity of the Philippine Institute of Volcanology and

Seismology (PHIVOLCS) towards use of accurate earthquake / tsunami information by the

departments and agencies related to disaster risk management, and (2) contributing to smooth

implementation of post-disaster rehabilitation and reconstruction by the Department of Public

Works and Highways (DPWH).

2-1-2 Outline of the Project

An outline of the Project is described below.

(1) PHIVOLCS

For the improvement of earthquake and tsunami monitoring capacity of PHIVOLCS, a

real-time earthquake monitoring system, a real-time tsunami monitoring system, and a tsunami

simulation database development hardware will be equipped.

As for earthquake monitoring, Japan has provided continuous assistance for PHIVOLCS to

enhance its earthquake and volcano monitoring capacity. In this Project, considering the

situation that the time for some of the earthquake monitoring equipment to be renewed has

come, as well as challenges and lessons learnt from the 2004 Sumatra-Andaman Earthquake and

the 2011 Great East Japan Earthquake, the earthquake monitoring network of PHIVOLCS is to

2-2

be extended and to be made real-time. Specifically, broadband strong motion seismometers,

strong motion seismometers, and earthquake intensity meters will be procured. In addition,

necessary equipment and software for real-time earthquake information transmission and for

connection with the existing earthquake information system of PHIVOLCS- the earthquake

analysis and monitoring system of the headquarters- will be supplied

Through the procurement, earthquake analysis, magnitude calculation, and nationwide

mapping of intensity scale will become possible with high accuracy. Moreover, by swiftly

transmitting this earthquake-related information to each organization concerned with disaster

management, it is expected to be utilized effectively for transmission of adequate warnings,

disaster prevention and mitigation, damage estimate and disaster control.

Regarding tsunami monitoring, no tsunami monitoring network has been established yet in

the Philippines. Thus, the real-time tsunami monitoring system to be installed by this Project

will be the first nationwide one in this country. Tsunami wave detectors and tsunami data

transmission stations will be equipped as well as a tsunami information system- a data receiving

center at PHIVOLCS headquarters. Moreover, towards accurate and swift warnings

concerning tsunami, it is indispensable to build up a database that accommodates tsunami

simulation results of each case, which is assumed to happen around this country. Thus, a PC

Cluster that has necessary capability to do tsunami simulation calculations under various

conditions will be procured.

Currently, if an earthquake with a high enough intensity which is assumed to cause a risk of

generating a tsunami occurs, the necessity of evacuation, the areas where evacuation is required,

and the evacuation levels are judged based on limited information, such as epicenters and

magnitudes. However, by introducing the aforementioned tsunami monitoring equipment,

real-time tsunami monitoring will be made possible. Moreover, the establishment of a tsunami

database is also expected to be promoted and consequently comprehensive tsunami measures

can be realized in line with the results of earthquake analysis with high accuracy, which can be

obtained through the extension of the earthquake monitoring network. Therefore, more highly

accurate and quicker warnings than heretofore is brought to reality. Furthermore, it can be

expected that the assistance of the Project on tsunami monitoring to be adapted in the future will

lead to the establishment of a tsunami forecasting and warning system.

The components for PHIVOLCS are shown below in Table 2-1.

(2) DPWH

In order to strengthen DPWH’s capacity for disaster rehabilitation and recovery, mobile

drainage pumps will be provided by the Project.

After the Great East Japan Earthquake, it was still new in our mind that water drainage was

one of the great challenges in the tsunami affected areas, and the usefulness of mobile drainage

pumps was recognized anew. Since tsunami risk is high and floods are frequent in the

Philippines, it is expected that provision of mobile drainage pumps will help for efficient flood

disaster response and immediate rehabilitation and recovery in the flood affected areas.

2-2-1 Design Policy

2-2-1-1 Basic Policies

(1) Principles






“Preparatory Surveys on the Project for Improvement of Equipment for Disaster Risk

Management” (hereinafter referred to as “the survey”) pursuant to “Basic Guidelines for

Reconstruction in response to the Great East Japan Earthquake (July 29, 2011, by

Reconstruction Headquarters in response to the Great East Japan Earthquake)” in order to

formulate Japan’s Grant Aid projects to be implemented by the fiscal 2011 third supplementary

budget of the government of Japan (GOJ).

In implementing the Project, equipment and materials are planned to be principally procured

from Japan and/or locally. Moreover, details of procurement conditions are discussed and

determined based on the said Basic Guidelines.

(2) Scope of the Project

During the field survey, discussions on the requested items, reasons and priorities were

undertaken, and the background of the request was confirmed through the survey on the existing

equipment. After the survey, further studies and analyses were made in Japan, based on the

above-mentioned basic policies, to determine the equipment specifications and quantities.

Since the Exchange of Notes (E/N) of this Project has been signed already, it was required to

determine the scope of the Project to make it within the grant shown in the E/N.

Details of each equipment component determined through discussions with the Implementing

Agencies, the field survey, study and analysis, are described in “2-2-2 Basic Plan (Equipment

Plan)” hereinafter.

2-2-1-2 Policy towards Natural Conditions






2-5




Designs will be made as specified in consideration of the various tropical climate specific

conditions, such as high temperature and high humidity, pluvial storms, and lightning strike,

since target sites of this project are scattered nationwide in the Philippines.

Especially, regarding the measures to protect PHIVOLCS’s equipment from lightning strike,

PHIVOLCS requested the Japanese side to adopt circuit interception by lightning arresters

instead of installing lightning rods, since they experienced in the past that their equipment was

struck by lightning through the lightning rods. The Japanese side will plan the measures

considering their requests.

Furthermore, concerning tsunami wave detectors, measures to prevent chloride damage will

be taken, in addition to making designs by assumed heights of tsunami wave and assumed

tsunami wave load.

2-2-1-3 Policy towards Socio-economic Conditions

In order to minimize the financial burden on the Implementing Agencies (PHIVOLCS,

DPWH), the equipment plan is designed with consideration to the least practical operation and

maintenance costs. And, considerations are made on protection from theft.

Moreover, the equipment deployment plan is made together with considerations of three

major regions; Luzon, Visayas and Mindanao.

2-2-1-4 Policy towards Local Procurement Conditions and Commercial Practice

Among the equipment that is planned to be installed in this Project, the earthquake and

tsunami monitoring equipment, such as sensors, and data transmission equipment contain

products that are defined under Japan’s Foreign Exchange and Foreign Trade Act as goods or

technologies that are subject to regulation. When the products are exported from Japan, due

formalities need to be followed to obtain permission for export based on the Act. The

procurement of the aforementioned equipment will not be any problem after obtaining

permission for export. However, in formulating the operation plan, the necessary time periods

for the aforementioned formalities to obtain export permission and other required export

procedures need to be taken into account.

2-2-1-5 Policy towards Employing Local Contractors and Consultants

As described above, the equipment covered by the Project is to be basically manufactured in

and procured from Japan, while small scale construction works for foundation and fence works

will be carried out by local contractors. Unpacking, delivery, assembling and installation will

be conducted by local workers under Japanese engineers’ instructions.

2-6

2-2-1-6 Policy towards Operation and Maintenance

Since the Implementing Agencies (PHIVOLCS and DPWH) are operating similar equipment

and systems, they have organizational abilities on operation and maintenance even for the new

equipment and systems covered by the Project, and the financial status of each Implementing

Agency is sound. Thus, each agency is deemed to have capability for operation and

maintenance of the new equipment procured by the Project.

Regarding the assistance for PHIVOLCS, after the installation of the real-time earthquake

and tsunami monitoring systems, instruction regarding initial operation is planned to be given

on operation methods and maintenance and inspection methods by engineers of the

manufacturers. Furthermore, no a soft component (technical assistance) is judged to be

required, since the existing earthquake monitoring systems have been operated and maintained

at a high level by PHIVOLCS staff that have obtained advanced technical skills.

As for DPWH, operation and maintenance training for the mobile drainage pumps will be

conducted by the Supplier, while a soft component is not included in the Project since special

skills and knowledge are not required for operation and maintenance of mobile drainage pumps.

2-2-1-7 Policy towards Grades for Equipment

Grade and specifications of the equipment to be provided by the Project are to meet with

Japan’s and/or international standards. Equipment which has been developed based on lessons

leant from the Great East Japan Earthquake and state-of-art technology in Japan will be

procured as much as practical.

2-2-1-8 Policy towards Method of Procurement and Project Implementation Period

The Procurement Agency (Japan International Cooperation System: JICS) will conduct the

procurement services for the Project on behalf of the Implementing Agencies, and the

equipment will be procured through open competitive tender(s).

As described above, this Project has two Implementing Agencies (PHIVOLCS and DPWH).

Since the types of equipment and required procurement time period for PHIVOLCS and DPWH

are quite different, two separate tender packages will be conducted.

This Project aims at disaster prevention and disaster risk mitigation with urgent needs. It is

essential to procure such equipment as soon as possible in order to contribute to improvement of

disaster prevention and disaster risk mitigation. Therefore, it is decided to conduct

procurement of the DPWH package first, while detailed and technical studies for the

PHIVOLCS package are carefully carried out.

The expected implementation schedules are shown in “Table 2-16 Implementation Schedule

(PHIVOLCS)” and “Table 2-17 Implementation Schedule (DPWH)” hereinafter.

2-2-2-1 Principles

This Project is aiming at (1) improving the earthquake and tsunami monitoring capacity of

PHIVOLCS towards use of accurate earthquake / tsunami information by the departments and

agencies related to disaster risk management, and (2) contributing to DPWH’s smooth

post-disaster rehabilitation and reconstruction activities.

To attain the above-mentioned project goals, discussions with the Implementing Agencies,

the field survey and technical study / analysis were properly conducted. Since the E/N of this

Project has been signed already, it was required to determine the scope of the Project to make fit

it within the grant shown in the E/N.

The following table shows a comparison of the requested items confirmed in the Minutes of

Discussions (M/D) and the Project components determined through discussions with the

e. Mobile Drainage Pump incl. Operation and Maintenance Training

6 A 1. Mobile Drainage Pump 8 This item meets with the Project’s special considerations, and quantities of this item are increased since urgent necessity is recognized.


As mentioned above, equipment and materials are planned to be principally procured from

Japan and/or locally. Moreover, details of procurement conditions are discussed and

determined based on the said Basic Guidelines. Thus, the equipment plan for the Project is

decided through technical studies in line with this basic policy.

The major changes from the initially requested items are as follows.

2-10

(1) PHIVOLCS Real-time Earthquake Monitoring System

The expansion of PHIVOLCS’s earthquake monitoring network will contribute not only to

the improvement in accuracy of earthquake monitoring, but also to the swift transmission of

more effective information and warnings for disaster management. In this regard, the

expansion will be done as the first priority. On the other hand, GPS continuous receiver for

land deformation monitoring will not be provided by the Project, because the introduction of the

devices is still in experimental phases even in Japan.

In addition, the equipment for earthquake information systems to the two mirror centers,

Tagaytay and Davao, will be excluded in the Project due to the limitation of the project budget.

(2) PHIVOLCS Real-time Tsunami Monitoring System

In the initial request, the number of the target sites was 20. However, since studies on

current situations of the target sites conducted during the field survey revealed that an

appropriate area for the installation of the equipment could not be secured in one of the target

sites, 19 sites have determined to be considered as targets. The details of the site selection are

mentioned below in Section 2-2-2, “Equipment Plan (2) PHIVOLCS Real-time Tsunami

Monitoring System”.

As is the case of the equipment for earthquake information systems, the equipment for

tsunami information systems will not be installed in the two mirror centers.

(3) PHIVOLCS Real-time Volcano Monitoring System (Bulsan Volcano)

Initially, the equipment, such as broadband seismometers and ultrasonic sensors that have

been installed in Taal Volcano (Buco earthquake and volcano monitoring station) and in Mayon

Volcano (Mayon earthquake and volcano monitoring station), was requested to be set in

Bulusan Volcano (Sorsogon earthquake and volcano monitoring station). However, it is

judged that the equipment for earthquake and tsunami monitoring have higher priority than

volcano monitoring. This judgment was confirmed in the M/D through the discussions in

Philippines. Due to the budget limitation, this equipment will not be included in the Project.

(4) DPWH Heli-borne Oblique Photography System and Other Relevant

Sub-components

This photography system is not only to take photos from a helicopter but also to identify the

exact location (coordinates) even though photos are captured from angled positions. Thus, this

is very effective to grasp the exact location of the affected area together with damage situations,

and rapid disaster response can be implemented if the system is introduced. On the other hand,

this item is quite costly and long-term technical assistance is required for proper operation.

Based on comprehensive discussions, it is deemed to be very unfortunate but difficult to procure

such item by this Project under the grant aid scheme.

2-11

(5) DPWH Bridge Inspection Vehicle

The major transportation means in the Philippines is by road. However, it is a concern that

the approx. 8,000 bridges in the whole country might be bottlenecks to road transportation when

disasters occur. Most of the bridges were constructed 30-40 years ago, and structural

inspections and maintenance of bridges are big challenges, while DPWH is trying to improve its

capacity for bridge inspection and maintenance. Currently, DPWH has two bridge inspection

vehicles, which were procured by JICA’s technical cooperation project “Improvement of

Quality Management for Highway and Bridge Construction and Maintenance Phase I

(hereinafter referred to as “TCP-I”)” and by the World Bank. The existing two bridge

inspection vehicles are well operated and maintained by the responsible DPWH Regional

Offices, which are the pilot regions of TCP-I and TCP-II (Phase II of the said technical

cooperation project), through training towards strengthening the capacity for bridge

maintenance.

However, unfortunately, as shown in Table 2-4, no concrete conclusion on the possibility of

products / parts manufactured in the affected area of the Great East Japan Earthquake could be

confirmed during the Preparatory Survey. Thus, based on the instruction from the Ministry of

Foreign Affairs of Japan, it was determined to exclude this item from the Project.

(6) DPWH Non-destructive Test Equipment

As described above, DPWH is trying to improve its capacity for road / bridge maintenance.

TCP-I has procured non-destructive test equipment (including concrete rebound hammer,

reinforced concrete detective radar, and infrared imager) for its three pilot regions, and TCP-I

and TCP-II did/will carry out training and prepare bridge maintenance manuals. The request

for this item for this Project was made for the other regions that were not covered by TCP-I

and/or II.

However, it was confirmed that the request was a duplicate of Japan’s loan project “Road

Upgrading and Preservation Project (RUPP), Asset Preservation Contract (APC) Component

and Preventive Maintenance (PM) Component”, which is supposed to be implemented from

2012 and will cover procurement of non-destructive test equipment for all other thirteen regions

besides the three regions already covered by TCP-I and II. Therefore, it was determined to

exclude this item from the Project.

(3) DPWH Mobile Drainage Pumps

The original request from DPWH was for six (6) mobile drainage pumps with drainage

capacity of 10 m3/ min. for two regions each from Luzon, Visayas and Mindanao.

After the Great East Japan Earthquake, it was still new in our mind that water drainage was a

great challenge in the tsunami affected areas, and usefulness of mobile drainage pumps was

recognized anew. Moreover, similar equipment accomplished great results for a severe flood

2-12

disaster in Thailand in 2011. Since tsunami risk is high and floods are frequent in the

Philippines, it is expected that provision of mobile drainage pumps will help for efficient flood

disaster response and immediate rehabilitation and recovery in the flood affected areas.

As described in “2-2-2-2 Equipment Plan (4) Mobile Drainage Pump” hereinafter, flood

disasters caused by tsunami, typhoons and heavy rains affect areas all over the Philippines.

Towards rapid rehabilitation and recovery after flood disasters, it is essential to introduce

mobile drainage pumps which can work for spot inundation of roads and/or low lying areas, as

well as improvement of the existing drainage pumps that are set as infrastructure will aid in

rapid rehabilitation and recovery as well.

Under this background, urgent need of mobile drainage pumps is confirmed. Furthermore,

the necessity of additional pumps is recognized after a series of floods occurred in July, August

and December 2012. After careful examination of the Project cost estimation, together with

considerations regarding the grant described in the E/N and balance of packages for the both

Implementing Agencies, it was determined to include eight mobile drainage pumps to be

provided by the Project.

2-13

2-2-2-2 Equipment Plan

Details of the equipment plan of this Project are mentioned below.

(1) PHIVOLCS Real-time Earthquake Monitoring System

Improvement in the accuracy of data processing and analysis in PHIVOLCS headquarters

will be made possible by acquiring earthquake and intensity information with the broadband

strong motion seismometers, strong motion seismometers and earthquake intensity meters that

will be installed in each target site and by transmitting the information in real time to the

headquarters through satellite communication channels or the internet.

Each component of the equipment that comprises the real-time earthquake monitoring system

is mentioned below.

1) Broadband Strong Motion Seismometer

In 10 out of the 31 existing unmanned seismic stations, broadband seismometers and

strong motion seismometers have been installed by “Enhancement of Earthquake and

Volcano Monitoring and Effective Utilization of Disaster Mitigation Information in the

Philippines” being implemented as a project of the Science and Technology Research

Partnership for Sustainable Development (SATREPS) through collaboration between two

Japanese government agencies: the Japan Science and Technology Agency and the Japan

International Cooperation Agency (JST-JICA). The seismometers have been utilized for

long-period motion monitoring, identification of seismic center, and calculation of

magnitudes. However, it has been pointed out that broadband seismometers go off scale

when a giant earthquake, such as the Great East Japan Earthquake, occurs. Currently,

installation of broadband strong motion seismometers that can monitor giant earthquakes is

an urgent need in Japan. In the Philippines, considering the lessons learnt out of the

experience of the Great East Japan Earthquake, broadband strong motion seismometers will

be set in the 10 unmanned seismic stations where broadband seismometers have already

been installed.

At such 10 unmanned seismic stations, concrete foundations for earthquake monitoring

equipment have been constructed through Japan’s grant aid or other assistance in the past.

Therefore, the broadband strong motion seismometers will be installed onto the existing

foundations.

a. Broadband Strong Motion Seismometer and Digitizer

Regarding broadband strong motion seismometers, it has been confirmed that products

which meet the required specifications are manufactured in the affected area of the Great

East Japan Earthquake.

On the other hand, digitizers are required to be electric power saving types due to

restrictions in land conditions that are mentioned below. Moreover, it is also necessary to

consider past records of digitizer’s connections with the existing earthquake monitoring

systems that are established mainly with the products of Nanometrics Inc. (Canada).

Considering these 2 points together, technical discussions were made with PHIVOLCS, it

concluded that the specified model of digitizer manufactured by Nanometrics Inc. is to be

procured.

b. Satellite Communication System

All the unmanned seismic stations have been equipped with satellite communication

system, and the monitoring data are transmitted in real time to PHIVOLCS headquarters

2-17

and the mirror centers. Even for the broadband strong motion seismometers to be

installed by the Project, the existing satellite communication system will be utilized (See

Figure 2-1).

If a broadband strong motion seismometer co-exists with the existing strong motion

seismometer, there will be risks that the number of the devices will exceed the number

which can be serviced by the current satellite communication system. Considering the

fact that broadband strong motion seismometer can cover the function of strong motion

seismometer as well as the communication expenses borne by PHIVOLCS, it is decided

that the existing strong motion seismometer will be replaced by a broadband strong motion

seismometer.

c. Power Supply System

In the unmanned seismic stations that will be the target sites for the installation of

broadband strong motion seismometers, electricity is supplied through independent power

systems using solar power generation. The necessary electricity for the equipment

installed by this Project is planned to be provided by locating additional solar panels, and

the equipment will not be connected with the power sources for the existing facilities.

The capacities of the solar panels and batteries have been decided to be the ones that enable

electricity to be supplied for up to 3 days without any sunlight.

The solar panels are to be installed on the foundations and frames newly provided.

Special anti-theft type bolts, nuts and screws will be applied for a certain number of joints

between foundation and frame and between frame and panel.

While the shapes of the compounds of unmanned seismic stations differ site by site, the

compounds are narrow and surrounded with approximately 5 to 6 meters square large

fences. Besides, the space for installing new equipment outside is limited, since

earthquake monitoring equipment has already been located in the available area. Thus,

for certain stations that do not have sufficient space to set additional solar panels,

PHIVOLCS will acquire necessary land or retain the right for land use.

2) Strong Motion Seismometer

PHIVOLCS has 30 manned seismic stations and 6 volcano observatories besides the

above-mentioned 31 unmanned seismic stations. Among all the 36 manned stations, the

29 seismic stations and the 6 volcano observatories have been equipped with strong motion

seismometers through Japan’s grant aid projects. However, more than 10 years have

passed since the provision of the equipment, and thus they are up for renewal. In addition,

the existing equipment does not have real-time telemetering system. Therefore, new

strong motion seismometers will be installed for replacement at all the 36 manned stations,

2-18

and satellite communication system for strong motion seismometers will be newly

established.

All sites for strong motion seismometers are the existing stations where the concrete

foundations for seismometers are available. Thus, these existing foundations will be

utilized to install the new strong motion seismometers.

a. Strong Motion Seismometer (Sensor) and Digitizer (Processor)

Regarding strong motion seismometers (sensor), it has been confirmed that products

which meet the required specifications are manufactured in Japan and that the products can

be procured as the ones manufactured by including the parts made in the affected area of

the Great East Japan Earthquake. As is the case of the Japan Meteorological Agency

(hereinafter referred to as “JMA”), the strong motion seismometers procured by this Project

will be the ones called JMA type seismometers, which have functions of calculating

seismic intensity as well as acceleration waveform data. The strong motion seismometers

are required to show seismic intensity on the monitors at the stations and also to transmit

the information to PHIVOLCS headquarters.

As for the digitizers (processor), products made in Japan have the functions of

transmitting seismic intensity data. However, regarding the transmission of acceleration

waveform data, Japan’s one-of-a-kind formats, such as WIN formats and/or WIN32

formats, are generally adopted. It is essential to consider the Japan-made digitizer’s

connectivity with the existing systems that mainly consist of the products manufactured by

Nanometrics Inc. As a result of hearing surveys to manufacturers of Japan-made

digitizers, it has been confirmed that Seed formats, which are widely used around the world

and are able to exchange data with the systems of Nanometrics, can solve the issue of the

connectivity. Thus, Japan-made digitizers with additional functions corresponding to

Seed format will be procured by the Project.

b. Satellite Communication Systems

As shown in Figure 2－1, additional satellite communication equipment for data

transmission is not required in the 4 manned stations, because the seismic station in

PHIVOLCS headquarters transmits data through LAN, and because the 3 volcano

observatories at Buco, Mayon, and Canlaon have already been equipped with satellite

communication systems. Satellite communication equipment will be installed in the 32

manned stations, excluding the aforementioned 4 stations, for establishment of real-time

monitoring networks with strong motion seismometers. Currently, PHIVOLCS is using 2

kinds of satellite communication services, namely ABS and IP-Star. Considering the

burden of operation and maintenance costs that will be borne by PHIVOLCS, IP-Star,

which is relatively reasonable in communication costs and whose communication capacity

is relatively sufficient within the scope of the existing contract, will be basically adopted.

2-19

However, since IP-Star does not cover some areas in the Philippines, ABS will be adopted

in the areas that are out of the IP-Star-service-coverage areas. Moreover, because

Nanometrics Libra used for ABS has become out of date due to model change of the

product, and because procurement of the spare parts for the model is getting difficult, the

succeeding model, Libra II, will be adopted. The receiving equipment and systems that

are necessary for each satellite communication network will be mentioned below in Section

2-2-2, “5) Earthquake Information Systems”. Concerning procurement source of the

satellite communication equipment, the equipment will be procured as brand specified

products manufactured in the third countries, because both IP-Star and ABS systems need

to be used with the systems of local satellite communication companies and also to be

connected with the existing earthquake monitoring systems.

c. Seismic Intensity Scale

Seismic intensity information is required to be displayed on monitors which will be

installed at the targeted manned stations and also to be transmitted to PHIVOLCS

headquarters (See Figure 2－2). As for calculation formulas for seismic intensity, the

formula based on PHIVOLCS earthquake intensity scale (PEIS), which was developed by

PHIVOLCS with the technical support of SATREPS, is planned to be utilized. However,

after the operation of the formula is started, adjustment of parameters of the formula may

be required to make it possible for the correlation between seismic intensity and actual

earthquake damages to more precisely reflect real situations. The strong motion

seismometers procured by this Project will have functions of updating parameters of the

formula. The details of formula will be mentioned below in Section 2-2-2-2, “5)

Earthquake Information Systems”.

d. Power Supply System

In the manned stations where the strong motion seismometers will be installed by the

Project, electricity is basically supplied with commercial power sources. However, in this

Project, the equipment will not be connected with the existing power systems, but

electricity will be provided by independent solar power systems in order to enable satellite

communication to be as continuous as possible even in an emergency. The capacities of

solar panels and batteries have been decided to be the ones that enable electricity to be

supplied up to 3 days without any sunlight. As is the case for the broadband strong

motion seismometer, special anti-theft type bolts, nuts and screws will be adopted.

Concerning the strong motion seismometers installed in PHIVOLCS headquarters, they

will use the existing power sources in the headquarters, not only because the supply of the

electricity in the headquarters is stable, but also because back-up power supply in an

emergency is secured.

2-20

3) Earthquake Intensity Meter

In the Philippines, no instrumental seismic intensity monitoring network has been

established. Through SATREPS being implemented since 2010, the introduction of 100

sets of earthquake intensity meters has just started. Aiming at earthquake damage

forecasting and swift emergency responses, 240 sets of earthquake intensity meters

including the ones for replacement in emergency will be procured by this Project to

enhance the accuracy of earthquake intensity monitoring.

a. Earthquake Intensity Meter

Earthquake intensity meters are the Japan-made simplified-type seismic meters that were

researched and developed by “IT Kyoshinkei Consortium”, which promotes collaborative

study through industry-university cooperation between the Earthquake Research Institute of

Tokyo University as the leading figure, multiple private companies and research institutes.

Regarding earthquake intensity meters, it has been confirmed that products which meet the

required specifications can be procured as ones manufactured in the affected area of the

Great East Japan Earthquake.

The equipment consists of sensor part and monitor part. It calculates seismic intensity

from acceleration measured with the sensor part, displays the seismic intensity on monitor

screens, and transmits the information to PHIVOLCS via the internet.

The earthquake intensity meters procured by this Project will be interconnected with the

earthquake intensity network being established by SATREPS. The basic requirements for

earthquake intensity calculation and data transmission need will be same as the ones for

SATREPS.

b. Data Transmission Systems

Seismic intensity measured by the earthquake intensity meters are transmitted to

PHIVOLCS headquarters through the internet. The seismic intensity monitoring network

including the earthquake intensity meters procured by this Project is as shown in Figure 2

－2.

c. Installation Method

Any special skills are not required for installation and adjustment of earthquake intensity

meters. Therefore, all the equipment will be handed over at PHIVOLCS headquarters,

and PHIVOLCS will be responsible for site delivery, installation and adjustment of the

earthquake intensity meters. Upon handing over of the equi8pment at PHIVOLCS

headquarters, the guidance and demonstration on installation will be conducted by the

Supplier. Regarding the target sites of the earthquake intensity meters, mobile phone base

stations and/or local government offices have been considered as candidate sites. The list

2-21

of the target sites will be submitted to the Japan side once the sites are selected by

PHIVOLCS.

d. Parameter Up-date

As is the case of the strong motion seismometers, earthquake intensity meters need to be

programmed with the earthquake intensity calculation formulas based on PHIVOLCS

earthquake intensity scale (PEIS). The details of the formula will be mentioned below in

Section 2-2-2-2, “5) Earthquake Information Systems”.

Considering the fact that many earthquake intensity meters will be located at the

facilities that belong to the other entities and they will be connected through the internet,

remote updating methods via the internet will be adopted to change the parameters of the

earthquake intensity formulas, as shown in Figure 2－3.

Figure2-3 Methods of Parameter Upgrading on Earthquake Intensity Meter

4) Earthquake Acquisition Software (for PHIVOLCS Headquarters)

Data obtained by the earthquake monitoring equipment provided by this Project will be

transmitted in real time to PHIVOLCS headquarters and will be processed by the existing

servers. As described above, the existing earthquake monitoring system mainly consists

of the products of Nanometrics Inc. (Canada). Most of Nanometrics’s products adopt the

manufacturer’s original kinds of connectors and cables as well as data transmission format

(NMX format).

On the other hand, as mentioned above, the equipment provided by the Project shall be

basically procured from Japan. Most of Japan-made earthquake monitoring equipment

adopt WIN format which is Japan’s unique format developed by JMA, not NMX format,

while efforts of incorporating into the equipment Seed format and SeedLink format that are

being used worldwide have also been made.

In the existing PHIVOLCS system, monitoring data is acquired by using Naqs Server,

software manufactured by Nanometrics Inc., and then various kinds of data processing and

analysis are performed. However, the software does not have the functions of loading

data in WIN, Seed, and/or SeedLink formats. Therefore, some methods are required to

incorporate the data not in NMX format into the existing servers manufactured by

Nanometrics Inc.

In order to incorporate such data not in NM format into the existing servers, Apollo

Server manufactured by Nanometrics Inc., an advanced version of the existing earthquake

data acquisition software, is indispensable, since Apollo Server can load the data in NMX

format, Seed format, and SeedLink format. The software is planned to be introduced as a

brand specified product manufactured in the third countries.

Regarding the waveform data of strong motion seismometers, Apollo Server will

integrate the data after the data is acquired with Seiscomp3, free software developed by

German Research Centre for Geosciences (GFZ).

In addition, new PC workstations for earthquake data acquisition software will be

procured by the Project, considering the following concerning points; (1) the deterioration

of the existing PC workstations and (2) the memory shortage of the hard desk resulting

from the increase in the number of monitoring stations.

5) Earthquake Information Systems (for PHIVOLCS Headquarters)

a. Processing, Analysis, and Display of Seismic Intensity Data

Since the first instrumental earthquake intensity monitoring network is established in the

Philippines, servers, software, and monitors will be newly procured by this Project. As

for the equipment for the servers, it has been confirmed that products, which meet the

required specifications, have been manufactured in the affected area of the Great East

Japan Earthquake.

A display monitor will be installed at PHIVOLCS headquarters, and the data gathered

with the earthquake monitoring equipment installed by this Project will be indicated on

maps on the screen. JICA logos or ODA marks will be displayed on the monitor screen.

In addition, at the monitoring stations with strong motion seismometers, seismic intensity

will be displayed on the small-size monitors supplied with the digitizers.

2-23

The earthquake information system (seismic intensity display system) provided by the

Project is to be a simplified stand-alone type system which will show only the intensity

data monitored by the strong motion seismometers and earthquake intensity meters

installed by this Project. This is because it has been judged that it will take a considerable

amount of time to develop a comprehensive seismic intensity display system that

PHIVOLCS is willing to introduce. However, in order for future integration with the

comprehensive display system that PHIVOLCS will develop with the technical support of

SATREPS, MySQL will be adopted as the database for the earthquake intensity data.

Due to the limitation of the Project budget, the two mirror centers are excluded from the

target for the assistance of the Project.

b. Calculation Formula for Seismic Intensity and Seismic Intensity Scale

PHIVOLCS adopts “PHIVOLCS Earthquake Intensity Scale (PEIS)” which is the 10-tier

earthquake intensity scale PHIVOLCS has developed based on a Modified Mercalli

Intensity Scale (MMI) by U.S. Geological Survey (USGS). Moreover, PHIVOLCS has

independently developed a Rapid Earthquake Damage Assessment System (REDAS).

However, seismic intensity has been determined by body sense seismic intensity and the

extent of the earthquake damages, and mechanical measurement system of seismic

intensity has not been established yet. Under these situations, PHIVOLCS, with the

technical assistance of SATREPS, has newly developed the PEIS Earthquake Intensity

Calculation Formula based on the formula of the USGS ShakeMap. Additionally, apart

from the calculation formula, PHIVOLCS has also developed another method using

earthquake intensity conversion table (PGA-PGV-PEIS Table). Through a series of

discussions, it has been determined and confirmed that PEIS Calculation Formula and

PGA-PGV-PEIS Table will be adopted as the earthquake intensity calculation methods in

the Philippines for the seismic intensity monitoring system of PHIVOLCS (See

Annex-1and Annex-2 of Appendix 5-2, “Technical Notes (for PHIVOLCS) (signed on

December 7, 2012)”).

In this Project, the said two methods; the PEIS Calculation Formula and the

PGA-PGV-PEIS Table, will be adopted. The two methods are to be reflected in the

specifications of the strong motion seismometers, the earthquake intensity meters and the

equipment for the earthquake information systems installed at PHIVOLCS headquarters.

Here, it is worth noting that seismic intensity has been estimated based on body sense

seismic intensity and the extent of the earthquake damages1. Indicators of seismic

intensity scale shall be correlated with the extent of structural damages and causalities, and

thus it will vary according to the condition of building structure in each country. Thus,

1 Hachimine, T. （1989）. Shindo-no-Keisokuka-ni-tuite [On the New Instrumental Observation of the Seismic Intensity]. Quarterly

Journal of Seismology vol.52 no. 3-4 of separate volume (Japan Meteorological Agency)

2-24

regressive equations need to be adopted, which analyze the correlation with the damages

caused by the earthquakes in the past. However, such data of damages caused by the past

earthquakes have not been accumulated and examined sufficiently in the Philippines.

Therefore, after the earthquake intensity calculation formula is introduced, a correlation

analysis between the earthquake damages and the calculation formula will be conducted.

Moreover, the adjustment of parameters for the calculation formula is assumed to become

necessary to reflect the more actual situations of the Philippines. Considering the

above-mentioned arrangement, the equipment for seismic intensity monitoring procured by

the Project will be equipped with the functions of updating parameters.

6) Satellite Communication Equipment (for PHIVOLCS Headquarters)

As mentioned above, IP-Star will be basically selected as the satellite communication

system installed by this Project. However, at some sites located out of the IP-Star

coverage areas, Nanometrics Libra II for ABS, the succeeding system of Libra which is

currently utilized by PHIVOLCS, will be adopted.

Regarding ABS, the Libra that PHIVOLCS is currently employing has become obsolete,

and consequently the procurement of the spare parts is getting difficult due to model

change of the product. PHIVOLCS is planning to replace the Libra by the Libra II system,

and they have started the procurement process of the splitter for the Libra II. If the splitter

is installed, the existing antenna and modem for ABS can be utilized for both Libra and

Libra II. However, the existing hub stations of PHIVOLCS, namely Carina Hub

manufactured by Nanometrics Inc., are only for the Libra, and thus additional Carina Hub

for Libra II will be procured by the Project as a brand specified product. In addition, it

has been confirmed during the preparatory survey that ABS satellite system has its own

backup system.

On the other hand, there is no need to renew the existing IP-Star system at PHIVOLCS

headquarters. However, since the existing IP-Star systems do not retain redundancy, a set

of the satellite communication receiver equipment for IP-Star will be provided by the

Project.

Both IP-Star and ABS systems need to be operated by local satellite communication

companies and also to be connected with the existing earthquake monitoring systems.

The equipment procured by this Project will be brand specified products manufactured in

the third countries.

2-25

(2) PHIVOLCS Real-time Tsunami Monitoring System

As mentioned above, systematic tsunami monitoring network does not exist in the Philippines,

and establishment of tsunami monitoring network is recognized as an urgent challenge. The

“first” nationwide real-time tsunami monitoring system will be established by this Project.

In the Philippines, tsunami warnings are declared even current situations, however, necessity

of evacuation, warning areas and alert levels are determined with limited information such as

location of epicenter and magnitude, when earthquake with a tsunami risk occurred. Under the

present system, PHIVOLCS notifies tsunami warnings to the Office Civil Defense (OCD) by

FAX and SMS, and OCD announces the warnings to the relevant agencies and the mass media.

This Project will construct the new tsunami monitoring stations at tsunami prone areas

identified based on the hazard maps prepared by PHIVOLCS. Sea-level monitoring data will

be transmitted in real-time to PHIVOLCS headquarters, and it will contribute to higher accuracy

of tsunami warning and its lifting. Continuous and nationwide sea-level monitoring will make

possible to obtain exact and actual tsunami information, and moreover, it will contribute to

disaster mitigation with efficient and quick responses decided based on the real-time monitoring

data. In addition, accumulated sea-level monitoring data will be reflected into the tsunami

simulation, and accuracy of tsunami estimation will be improved. This real time tsunami

monitoring system is expected to be a core of the real-time tsunami warning system which will

be established in the future.

In the initial request, the number of the sites for tsunami monitoring stations was 20.

However, it was revealed through the site survey conducted during the field survey period that

appropriate locations for the equipment could not be secured at one of the candidate sites

(Rapu-Rapu). After the discussion with PHIVOLCS, the number of the sites for tsunami

monitoring stations was confirmed to be 19.

The site surveys were conducted in the presence of PHIVOLCS staff. At the candidate sites

located in the tsunami prone areas, selected by PHIVOLCS based on the tsunami hazard maps,

survey works were conducted to check whether appropriate locations for the equipment are

available or not, at port facilities or other neighboring facilities. The major survey items were

as follows

① Positional relationship between the site and trenches with high risks of earthquake occurrence or between the site and populated cities

② Confirmation of the owner of the land or facilities. Verbal agreement with the owner

on the installation of the equipment on the selected land or facilities

③ Confirmation of frequent berthing area and usage status of the jetty or pier

④ Checking the structural soundness of the harbor facility where ships are not anchored

⑤ Confirmation of the appropriate location(s) for tsunami wave detector

⑥ Topographic survey and sea-level measurement

⑦ Surveys on the appropriate location(s) for tsunami data transmission station (topographic

survey on open land or building where elevation is higher than the one for tsunami wave

detector and possible to install tsunami data transmission station)

The results of the site surveys were carefully analyzed and evaluated based on the following

criteria.

Importance Judgment

Rank a： Importance is very high because the site is facing tsunami prone trenches, or the importance of tsunami observation at the site is very high because of positional relationship with populated cities.

Rank b： The site is facing trenches with risk of tsunami, but it is close to inland sea or within bay.

Technical Judgment

Rank A： All the conditions concerned with the installation of tsunami monitoring equipment are met.

Rank B： Some of the conditions concerned with the installation (location or methods) are not satisfied, but alternative solution can be applied.

The evaluation results of the site surveys are shown in Table 2－7, “Results of Tsunami Site

Survey – Real-time Tsunami Monitoring System”.

All the sites are recognized to have high importance for tsunami monitoring. However,

Maricaban that is located near the inland sea, Basco that is some distance from trenches, and

2-28

Tacloban that is located on the inland sea and in the bay are classified as sites of Rank b in

terms of the importance.

Regarding the technical judgment, all the sites meet the conditions for the installation of the

tsunami wave detectors. Concerning the tsunami data transmission stations, there are sites

where elevated land or the existing facilities, which are suitable for the installation, could not be

identified. These sites are classified as Rank B. However, since most of these sites are facing

the Philippine Trench, whose importance for tsunami monitoring is considered to be particularly

high. As an alternative solution, reinforced concrete elevated platforms will be constructed,

and the equipment will be located on the platforms for the sites ranked B.

As a result of the project cost estimation, it was determined that all the 19 sites will be

included in the Project.

Tsunami Waveform Data ＜Legend＞

Blue：Equipment / System to be covered by the Project Gray：Existing Equipment / System

Figure 2-4 Satellite Communication Network Diagram for Real-time Tsunami Monitoring System

Details of each equipment which comprises the real-time tsunami monitoring system are

mentioned below.

1) Tsunami Wave Detector

The real-time tsunami monitoring system established by this Project will be the first

nationwide tsunami monitoring system in the Philippines. It is ideal that the sensor of the

tsunami wave detector is set at higher position than the assumed tsunami wave heights of

the area. However, considering the fact that this is the first tsunami monitoring network

of the country, the ease of installation, and the number of the installation sites to be secured,

it was determined that a large number of standard electric wave type or supersonic type

tsunami wave detectors to be deployed to the tsunami prone areas.

a. Tsunami Wave Detector

Radio wave type or ultrasonic type tsunami wave detectors, which are normally used by

Japan Meteorological Agency, will be adopted. It has been confirmed that tsunami wave

detectors, which meet the required specifications, can be procured from the affected areas

of the Great East Japan Earthquake.

2-31

In Japan, radio wave type tsunami wave detectors, for which the influence of the

temperatures and winds does not have to be adjusted, have been recommended. However,

the present models of radio wave type tsunami wave detectors are not able to respond to

drastic change of water level. In the case of Japan, especially after the Great East Japan

Earthquake, variety of tsunami monitoring equipment, such as pressure type tide gauges,

ocean bottom pressure, and GPS buoys are adopted as well as radio wave type tsunami

wave detectors in order to supplement each other, and consequently, no problems are

caused with use of radio type detectors. In the case of the Philippines, combined use of

different types of tsunami monitoring equipment is not easily expected at least in the near

future, since it is the first real-time tsunami monitoring system in the country.

If the selection is made among the existing models of tsunami wave detectors, it can be

considered that ultrasonic type tsunami wave detectors, which can respond to drastic

changes of water level, have to be adopted. However, new models of radio wave type

tsunami wave detectors that can meet the requirements are being developed, and it may be

available before the tender for this Project. Therefore, it is determined that both radio

wave type and ultrasonic type can be allowed with the conditions of “to be able to respond

to change of water level with 2.0 m/s or greater”, and this requirement shall be stipulated in

the equipment specification.

b. Radio Communication Equipment

The tide level data measured by the tsunami wave detectors will be transmitted via

radios to the tsunami data transmission stations located in line-of-sight areas within the

distance of several-hundred-meters. The tsunami wave detector and its auxiliary

equipment will be mounted to stainless steel poles. Thus, low power consumption type

radio communication equipment (for telemetry network) will be adopted to minimize the

number of solar panels and batteries.

c. Power Source

Electricity will be supplied with independent solar power systems so that data

transmission in an emergency can be as continuous as possible. The capacities of the

solar panels (chloride corrosion protective type for splash area) and batteries have been

decided to enable supply power for 3 days without any sunlight. As is the case for the

earthquake monitoring systems, special anti-theft bolts, nuts and screws will be adopted.

d. Assumed Tsunami Height and Designed Height of Equipment

As shown Figure 2－5, most of the tsunami waves that reached the Philippines in the

past were below 2.0 meters in height. Based on the past records, the tsunami height for

designs of the tsunami wave detectors has been set as 2.0 meters. If tsunami wave hits

wall, the height will be increased threefold. Thus, the 6.0-meter height is required to

2-32

protect the detector from 2.0-meter height tsunami wave. While the structures and ground

levels of the installation points for the tsunami wave detectors differ site by site, the heights

of the sensors have been set at 6.0 meters above the sea level for all the sites regardless of

different conditions of each site, with technical consideration at safe side. In addition,

though the batteries will be placed within waterproof cases, the bottoms of the cases will be

set at 2.0-meters above the jetties or revetments in order to secure the cases as thoroughly

as possible from being submerged. Additionally, concerning the foundations and poles

for the detectors, the structures have been designed based on the condition of the assumed

tsunami height of 2.0 meters.

Figure 2-5 Heights of Tsunami Waves reached to the Philippines since 1990

2) Tsunami Data Transmission Station

The equipment installed on jetties or revetments are likely exposed to surges, and the

equipment may be submerged if big tsunami waves come. Considering this, the

equipment needs to be waterproofed, but it is difficult to waterproof all the equipment in

terms of costs. Thus, only the essential equipment, i.e. the tsunami wave detectors, will

be installed on jetties or revetments, and the other equipment for data logging and

transmission will be placed on the different location that is several hundred meters far from

the coast line.

a. Data Logger

Data loggers will be installed in order for averaging tide level data received via the radio

communication equipment, as well as for data transmission to PHIVOLCS headquarters

through the satellite communication systems. Data logger shall have long-term data

storage functions (for 1 year) in order to make it possible to retrieve the observed data even

in case of network disturbance of the satellite communication systems.

2-33

b. Satellite Communication System

Satellite communication networks will be established for the real-time tsunami

monitoring network. As is the case of the real-time earthquake monitoring system,

IP-Star will be basically adopted for satellite communications, while ABS Libra II will

cover the sites located out of IP-Star service coverage areas. The equipment will be

procured as brand specified products manufactured in the third countries, because both

IP-Star and ABS systems need to be used with the systems of local satellite communication

companies and also to be connected with the existing earthquake monitoring systems.

c. Power Source

Electricity will be supplied with independent solar power systems so that data

transmission in an emergency can be as continuous as possible. The capacities of the

solar panels (chloride corrosion protective type for splash area) and batteries have been

decided to enable supply power for 3 days without any sunlight. Special anti-theft bolts,

nuts and screws will be adopted, as is the case for the other monitoring sites.

d. Designed Height of Equipment

Both data transmission functions and data storage functions can be secured as much as

practical, even when tsunami waves greater than 2.0 meters reach the areas. For this purpose,

the tsunami data transmission stations will be basically placed on elevated ground or on upper

floors of the existing buildings. If appropriate locations are not available, reinforced concrete

elevated platforms whose height is higher than the bottoms of the battery cases of the tsunami

wave detectors will be constructed, and the equipment will be installed on the platforms.

3) Tsunami Information System (for PHIVOLCS Headquarters)

The data obtained by the tsunami monitoring equipment provided by this Project will be

transmitted in real time to PHIVOLCS headquarters and then will be processed with the

tsunami information system that will be newly established by this Project.

a. Processing, Analysis, and Display of Tide Level Data

PHIVOLCS headquarters will be equipped with servers and monitors, and a system to

display the tide level data monitored at each site will be established. On the monitor

screens, graphic charts of comparison of the monitoring tide levels and the predicted tide

levels will be displayed for all the sites. As for the predicted tidal levels, initial settings

will be made by the Supplier. Specifically, necessary information for predicted tidal

levels, calculated based on harmonic analysis using the available detected tidal data for the

neighboring areas, will be prepared and incorporated into the server by the Supplier.

However, such initial prediction can not be so accurate because initial calculation will be

made based on the data from the neighboring area. After accumulating the actual detected

2-34

data, PHIVOLCS needs to conduct harmonic analysis with such actual data, and

parameters will be adjusted for each monitoring site.

JICA logos or ODA marks will be displayed on the monitor screens.

Due to the limitation of the project budget, the two mirror centers are excluded from the

Project.

b. Satellite Communication Equipment (for PHIVOLCS Headquarters)

Regarding satellite communication equipment in the headquarters for receiving the data,

the equipment for the real-time earthquake monitoring system will be utilized for tsunami

monitoring system as well.

(3) PHIVOLCS Tsunami Simulation Database Development Hardware

In the Philippines, tsunami simulation database has not been established yet. Under the

current situation, the necessity of evacuation, the areas where evacuation will be required and

the alert levels are judged only with the limited information such as the seismic center and the

magnitude. Consequently, warnings have not been transmitted accurately and swiftly.

PHIVOLCS is currently developing a tsunami simulation database with the technical

assistance of SATREPS. However, the PC cluster that is now in use does not have sufficient

capacity to carry out calculations for the tsunami database, and it takes a long time for

processing data. To establish the tsunami database as early as possible, a set of PC cluster with

appropriate specifications will be provided by the Project.

(4) Mobile Drainage Pumps

One of the remarkable disasters in the Philippines is flood caused by typhoons and heavy

rains. After the Great East Japan Earthquake, it was still new in our mind that water drainage

was a great challenge in the tsunami affected areas, and the usefulness of mobile drainage

pumps was recognized anew. For the purpose of strengthening the capacity of post-disaster

response, rehabilitation and recovery, six (6) mobile drainage pumps with drainage capacity of

10 m3/ min. were requested and through discussions during the field survey, it was confirmed

that each mobile drainage pump is to be deployed equally to the three major regions; Luzon,

Visayas and Mindanao.

As shown in the following table, approx. twenty typhoons approach the Philippines annually,

and they bring serious damages to the various areas of the country. Typhoon and flood prone

areas are almost all over the Philippines.

Towards rapid rehabilitation and recovery after flood disasters, it is essential to introduce

mobile drainage pumps which can work for spot inundation of roads and/or low lying areas, as

well as improvement of the existing drainage pumps that are set as infrastructure will aid in

rapid rehabilitation and recovery as well.

Under this background, urgent needs of mobile drainage pumps are confirmed. Furthermore,

the necessity of additional pumps is recognized after the series of floods that occurred in July,

August and December 2012. After careful examination of the Project cost estimation, together

with considerations of the grant described in the E/N and balance of packages for both

Implementing Agencies, it was determined to include eight mobile drainage pumps to be

provided by the Project.

As confirmed during the field survey, this Project will deploy two each mobile drainage

pumps equally to the three major regions; Luzon, Visayas and Mindanao. In addition, the two

mobile drainage pumps are to be deployed to the other regions in Luzon and Visayas that are

most likely to be affected by flood disasters.

According to “the Study on the Nationwide Flood Risk-Assessment and the Flood Mitigation

Plan for the Selected Areas in the Republic of the Philippines” conducted by JICA from 2006 to

2008, 30 river basins have significant inland flood problems among the 120 surveyed flooded

rivers. And, it is reported that most of the river basins have experienced inundation of one to

two days, while not a small numbers of river basins have experienced inundation of more than

one week.

Urban areas in the Philippines, especially cities / municipalities on flat land or along a river or

the ocean, tend to have inland floods very frequently. Though various projects for

improvement of flood mitigation and drainage facilities (such as river channels, gates, diversion

channels, and water drainage pumps) are being implemented in the major cities and

municipalities, there are still flooded spots in such urban areas. Inundation in the populated

areas brings not only water borne diseases but also harm to traffic and communication networks,

and consequently it disturbs rapid and smooth implementation of recovery and reconstruction in

and around the affected cities / municipalities. In fact, some cases have been reported where

serious disasters such as landslides caused by heavy rain occurred, rescue operation teams with

heavy machineries could not reach the sites due to spot inundation.

Under such situations, discussions were made with DPWH based on the said JICA’s

Nationwide Flood Risk Assessment, together with considerations of the recent flood disasters,

and finally the following eight cities/municipalities were selected as the high prioritized inland

flood prone areas.

As for the National Capital Region (NCR), responsibility for flood control and sewerage

management within NCR has been transferred from DPWH to the Metropolitan Manila

Development Authority (MMDA) based on “Republic Act No. 7924”, and formulation and

implementation of policies, standards, programs and projects for an integrated flood control,

drainage and sewerage system in NCR should be implemented by MMDA, in principle. On

the other hand, DPWH is responsible for road maintenance in the country including NCR.

Quick recovery of the road network from disaster, especially within and around Metro Manila

which is a node of the road network, will be a key factor in smooth implementation of recovery

and reconstruction in the entire Luzon, moreover the whole country. As shown in the

following figure, flood prone areas are spread in and around Metro Manila, and it is deemed

necessary for DPWH to have an emergency team for drainage activities in such flooded areas.

Therefore, one mobile drainage pump is to be deployed to DPWH Headquarters aiming at quick

recovery from road and spot inundation in and around Metro Manila.

Figure 2-6 Flooded Areas in Metro Manila and Neighboring Areas (2009 – 2012)

As for Region III (Central Luzon), DPWH originally requested to deploy the equipment to

Olongapo which is one of the flood prone areas, and it was confirmed on the M/D signed on

December 7th, 2012. However, DPWH asked the Team to change the location from Olongapo

to San Fernando, which is also a flood prone area and where the DPWH regional office is

located, is the most appropriate location for Region III. Considerations regarding the

frequency of flood disasters as well as resources for equipment maintenance were made, and

finally, the deployment location for Region III was concluded as San Fernando.

As for the other six selected cities / municipalities, they are well recognized as flood prone

areas, and DPWH regional offices are located in the cities / municipalities. Thus, it is deemed

appropriate to deploy the equipment there in terms of necessity, and the equipment will be well

maintained by each DPWH regional office.

2-2-4-1 Implementation Policy

(1) Principles

1) Organizational Arrangements

Since there are two Implementing Agencies for this Project, namely PHIVOLCS and

DPWH as shown in the Figure 2-7, the National Economic and Development Authority

(hereinafter referred to as “NEDA”) will act as Responsible Agency to coordinate between

the two Implementing Agencies. For implementation of the Project, a Consultative

Committee will be established, and the representative from the Philippine side will be

NEDA.

2) Exchange of Notes（E/N）

The contents of GADPR are decided by the E/N signed between GOJ and GOP. The

E/N enumerated the Project objectives, implementation schedule, terms and conditions, the

amount of the grant, and so on.

3) Grant Agreement（G/A）and Procurement Guidelines

Detailed procedures on procurement and services under GADPR were agreed between

the authorities of the two governments upon signing of the G/A.

Essential points agreed on the G/A are as follows:

2-58

JICA will supervise the implementation of the Project

Procurement of products and services shall be conducted in accordance with “The

Procurement Guidelines of Japan’s Grant Aid for Disaster Prevention and

Reconstruction (Type I-D)” established by JICA

The Recipient will conclude an Agent Agreement with the Procurement Agent

(hereinafter referred to as “the Agent”)

The Agent is the representative acting in the name of the Recipient concerning all

transfer of funds to the Agent

4) Procurement Agent

The Agent is designated to conduct the procurement services for products and services

(including fund management, preparation for tenders and contracts) for GADRP on behalf

of the Recipient. The Agent is an impartial and specialized organization that will render

services according to the Agent Agreement with the Recipient. The Agent is

recommended to the Recipient by GOJ and agreed between the two governments in the

Agreed Minutes (A/M).

5) Consultant

The Japanese Consultant that will be employed to do detailed design and supervise the本

work for the Project shall fulfill its roles in order to implement the Project smoothly and

achieve the purpose of the cooperation under the “Guidelines for Consulting Services

concerning Grant Aid” issued by JICA. The consulting firm therefore shall conduct all

necessary work and make efforts to be trusted by the Agent, the Responsible Agency and

the Implementing Agencies of the Project, considering fairness and neutrality for Japanese

suppliers.

(2) Utilization of Local Consultants and Contractors

In general, technical capability of the construction firms in the Philippines is high enough to

carry out the civil works required for the equipment for PHIVOLCS, such as concrete

foundation work and fencing work. Thus, construction supervision will be done by local civil /

building engineers, not by Japanese engineers.

As for installation works for PHIVOLCS equipment, sufficient technical knowledge and

skills are required for installation and adjustment of each of the equipment, especially for the

sensitive equipment, such as for monitoring system, communication system and servers. Thus,

installation works will be carried out by local contractors under proper instructions and

supervisions of the Japanese engineers from the Supplier.

2-59

2-2-4-2 Implementation Conditions

(1) Equipment Procurement

1) Procurement based on “Basic Guidelines for Reconstruction in response to the

Great East Japan Earthquake”

As mentioned above, in implementing the Project, equipment and materials are planned

to be principally procured from Japan and/or locally. Moreover, details of procurement

conditions are discussed and determined based on the said Basic Guidelines.

2) Products from the Third Countries

As mentioned above, the procurement in the Project will be basically done with the

principal policy of made in Japan. However, the satellite communication equipment will

be procured as brand specified products manufactured in the third countries, since services

of local commercial satellite communication companies are planned to be utilized. In

addition, some of the equipment and software required for connection with the existing

systems will be procured from the third countries by specifying the brands of the products.

(2) Transportation, Installation and Adjustment

The equipment for PHIVOLCS includes special and precision items, and therefore, it is

essential to dispatch the experts / engineers who have necessary technical knowledge for

transportation, installation and adjustment works for such PHIVOLCS equipment.

The equipment procured either from Japan, the third countries or the Philippines will be

tentatively accommodated in a warehouse in Metro Manila. Unpacking and numerical

inspection will be conducted in the warehouse, and then, the initial calibration of the equipment

will be carried out by the Supplier in presence of the Consultant’s engineer before repacking for

each site.

Since the Project sites (including the ones located in isolated islands) are spread nationwide,

and since various kinds of equipment are to be installed at such variety of Project sites, it is

important to make an efficient transportation plan linked with equipment installation plan.

Land transportation (by trucks) and marine transportation (by ferries) will be basically adopted

for domestic transportation from Manila to each site.

2-60

2-2-4-3 Scope of Works

The following table summarizes the responsibilities to be borne by GOJ and GOP for the

Project.

As for the sites located in the areas with security issues, the procurement of the equipment

will be implemented by Japan side, and the equipment for such site will be handed over at the

PHIVOLCS headquarters. PHIVOLCS will take the responsibility for necessary works after

handing over, such as transportation (site delivery), civil works, equipment installation and

adjustment works for such site. Precisely, the sites in the areas with security issues means the

ones located in the areas that MOFA has classified in their travel advice and warning as level 3,

“Recommendation to deferral travel”, or above, such as the western region of Mindanao Island.

2-61

However, if any alterations are made in the areas with security issues specified in the travel

advice and warning due to the changes in the security situations, the areas for installation work

will be reconsidered, if necessary (See Appendix 3-1, “Areas with security issues”).

(2) Quality Control Plan（Construction Works for PHIVOLCS package）

1) Principals

In preparation of the tender documents, the drawings will be developed considering the

conditions of the construction industry in the Philippines and the maintenance costs. As

for the technical specifications, reference will be made to the National Building Code and

National Structural Code of the Philippines, Japanese Architectural Standard Specifications

(JASS), Japanese Industrial Standards (JIS), Philippine National Standards (PNS) and the

standards of the American Society for Testing and Materials (ASTM), for the purpose of

securing high quality of construction.

During the construction periods, the Consultant will examine whether the construction

plans, including the implementing structure, construction and installation schedules, and

the shop drawings that will be submitted by the Supplier satisfy the conditions of the

contract documents and technical specifications, and give necessary approvals.

2) Inspections

On site, the Consultant will review the construction plans and material samples, which

will be submitted by the Supplier prior to the commencement of each category of the

construction work in terms of the conformity of construction materials and construction

quality with the relevant technical specifications and will give necessary approvals. After

the commencement of each category of the construction work the Consultant will conduct

inspections based on the approved construction plans according to the needs, and will give

necessary approvals. For conducting such inspections, the Consultant will develop check

sheets highlighting important check points that are identified based on the approved

construction plans. In this project, all the construction materials can be procured in the

Philippines. To ensure the required quality, random inspections will be conducted as

needed, as well as obtaining warranties issued by the manufacturers.

The construction work for the Project will be limited to very small scale works, such as

construction of equipment foundations and fences. Thus, both the Consultant and the

Supplier will manage the construction work by local engineers and supervisors.

Earth Work

The work plans considering appropriate methodologies for excavation, curing of

excavated surfaces, backfilling, compaction and concrete will be prepared, and the

works shall be conducted accordingly.

2-67

Re-bar Work

The confirmation of mill sheets submitted by the Supplier and random tension tests

will be conducted to ensure the required quality. In addition, the shop drawings

(re-bar placing plan and bending schedules) will be reviewed for approval and

inspection on re-bar arrangement regarding joints, anchorage, quantities and concrete

coverage for each element of reinforced concrete structures.

Concrete Work

The Project sites are located nationwide in the Philippines, and the site conditions

diversely vary place by place. The concrete will be delivered directly from concrete

plants to the sites with good access conditions. On the other hand, regarding the sites

that are not easily accessible, such as remote islands, on-site mixed concrete will be

adopted. The major quality control items of concrete work are as follows. The

following inspection will be implemented by the Supplier in presence of the

Consultant.

(a) Concrete Materials Material Item Method of Inspection

2-2-4-6 Procurement Plan

(1) Sources of Equipment

As mentioned above, the equipment procured by the Project will be principally from Japan.

However, the foundations for the monitoring and communication equipment and the security

fences for preventing burglaries will be locally procured in the country. Regarding satellite

communication equipment, brand specified products manufactured in the third countries, which

are compatible with the existing systems in the Philippines, will be procured either locally or

from the third countries, since services of local commercial satellite communication companies

are adopted. In addition, some of the equipment and software that are indispensable for the

connection with the existing system will be procured as brand specified products manufactured

in the third countries.

The lists of sources of the major equipment procured by the Project are show below.

(2) Transportation Plan

Regarding the equipment for PHIVOLCS, the installation and adjustment will be basically

conducted at each site. However, as mentioned above, the equipment for the sites located in

the areas with security issues will be handed over at the PHIVOLCS headquarters and then the

installation and adjustment will be conducted by PHIVOLCS.

As for the equipment for DPWH, the equipment will be delivered to the DPWH-FCSEC

located in Pasig city, Metro Manila, and initial operation and maintenance training and handing

over will be carried out in DPWH-FCSEC compound.

1) Equipment Procured from Japan (PHIVOLCS Package)

The equipment procured from Japan for the PHIVOLCS package will be shipped from

Yokohama and unloaded at the Port of Manila. The shipment from Yokohama to Manila

takes approximately one week. For custom clearance, one-week is usually required.

After the custom clearance, the Supplier will tentatively accommodate the equipment in a

warehouse in Metro Manila. In the warehouse, all the equipment will be unpacked to

conduct numerical inspection and initial calibration and then will be repacked to forward

the equipment to each site.

Since the Project sites (including the ones located in isolated islands) are spread

nationwide, and since various kinds of equipment are to be installed at such variety of

Project sites, it is important to make an efficient transportation plan linked with equipment

installation plan. Land transportation (by trucks) and marine transportation (by ferries)

will be basically adopted for domestic transportation from Manila to each site.

2-71

2) Equipment Procured from the Third Countries (PHIVOLCS Package)

Regarding some of the equipment and software required for the connection with the

existing monitoring systems and some of the satellite communication equipment, brand

specified products are to be procured from the third countries, because the same company’s

brand products as the existing systems have to be introduced. These products will be

procured mainly from Canada. They will be loaded in the Port of Vancouver. After

unloading and custom clearance in the Port of Manila, as is the case of the equipment

procured from Japan, the products will be tentatively delivered to a warehouse in Metro

Mania and then delivered to each site.

3) Equipment Procured from the Philippines (PHIVOLCS Package)

Some equipment for satellite communications, foundations for equipment and security

fences are to be procured locally.

Such equipment will be procured in Manila and initially accommodated in a warehouse

same as the equipment procured from Japan. The locally procured equipment will be

repacked together with those from Japan for the delivery and transport to each site.

On the other hand, general construction materials will be basically procured within the

areas of each site. Only for sites located on remote islands, such construction materials

are to be procured and delivered by chartered boats from cities on big islands nearby.

4) Equipment Procured from Japan（DPWH package）

The equipment for DPWH to be procured in Japan will be shipped from the Port of

Yokohama and unloaded at the Manila Port. It takes about one week from Yokohama to

Manila for marine transport, and another one week will be required for custom clearance at

Manila. After custom clearance, the equipment will be transported to DPWH

compound(s) located in Metro Manila by the Supplier.

2-72

2-2-4-7 Initial Operation and Maintenance Training Plan

(1) PHIVOLCS

Regarding the equipment for the monitoring sites among the equipment for the real-time

earthquake and tsunami monitoring systems, the Supplier’s engineers who will accompany the

installation teams will make brief guidance about the equipment on site. After the completion

of the installation at all the sites, the initial operation and maintenance trainings on the

earthquake and tsunami monitoring systems will be implemented in Manila or on the sites near

Manila. The trainings will take approximately 3 days each. The brief guidance on site and

the initial trainings in Manila will be conducted together with the installation work. The

adjustment and initial operation of the PC cluster will be also done simultaneously.

(2) DPWH

Prior to handover of the equipment, the engineers that will be dispatched from the Supplier

(practically, engineers from the manufacturer) will conduct the initial operation and

maintenance training for the mobile drainage pumps, and the training shall be held in the

DPWH-FCSEC compound along Pasig River.

2-2-4-8 Soft Component (Technical Assistance) Plan

Both Implementing Agencies (PHIVOLCS and DPWH) have been running similar equipment

/ systems, and they operate and maintain the equipment / systems in a proper manner. And

also, their financial conditions for operation and maintenance are deemed sound. Thus, it was

recognized that both Implementing Agencies have adequate capacity for operation and

maintenance for the new equipment provided by the Project.

As for PHIVOLCS, after the installation of the real-time earthquake and tsunami monitoring

systems, the initial operation and maintenance training will be conducted by from the Supplier

(practically, engineers from the manufacturer). Considering a good practice of operation and

maintenance of the existing systems by the well-skilled staff of PHIVOLCS, and also

considering the technical assistance from the on-going SATREPS which will be continued to

2014, this Project will not provide a Soft Component for the said equipment.

For DPWH, as well as PHIVOLCS, the initial operation and maintenance training will be

provided prior to handover. Since special skills and knowledge are not required for Mobile

Drainage Pumps, this Project will not provide a Soft Component for the said equipment.

2-73

2-2-4-9 Implementation Schedule

Procurement for this Project will be conducted by the Agent (JICS) on behalf of the Recipient,

by the method of open competitive tender. Since there are two Implementing Agencies

(PHIVOLCS, DPWH), and since the types and implementation schedule periods for

PHIVOLCS and DPWH are quite different, it was determined to separate tender packages by

the Implementing Agencies.

This Project aims at disaster prevention and disaster risk mitigation. It is essential to

procure such equipment as soon as possible in order to contribute to improvement of disaster

prevention and disaster risk mitigation. Therefore, it is decided to conduct procurement of the

DPWH package first, while detailed and technical studies for PHIVOLCS package are carefully

carried out.

The most rational implementation schedules for PHIVOLCS and DPWH packages are shown

below.
