5 CONSTRUCTION PROCEDURES

5.0 Design and Work Procedure

The temporary road T3 is planned and will be constructed based on the “Design Policy” as

separately submitted on the Contractor letter NNP1-PCL-00126 dated 20th February 2014.

The procedure of construction is shown below.


NNP1-MS-RW038-A1


5.1 Survey Work

Figure-3 Conceptual drawing of survey

Firstly temporary benchmarks for elevation and coordinate are established at

approximately 100m intervals.

Secondly, the centerline of the road alignment is identified on site with offset pegging

considering the design alignment. After completion of the centerline survey, the cross

section survey is carried out by minimum 20~25m intervals. And then, based on cross

section survey results, embankment and excavation area can be identified on site.

In case the original design alignment will not be suitable for the actual site condition, the

design alignment will be modified and corrected inside the designated area by the Owner.

Survey instruments shall be calibrated in accordance with the section 5.3.3 testing

equipment and facilities of the Quality Assurance Program (Document No. NNP1-PRG-

DrQAP-A3) in the NNP1-PCL-00086, dated 16th Jan. 2014.

Owner.


NNP1-MS-RW038-A1


2) Clearing shall consist of the removal and disposal of trees, stumps, logs, bush,

undergrowth, grass, crops and loose vegetable matter above a ground level.

When unsuitable materials stay under a ground level, it will be removed and

replaced with suitable materials.

3) Basically it is confirmed that commercial timber along the T3 temporary road

has been already cleared by the Lao government. If commercial timber is found

on site, the branch shall be trimmed, and the timber trees shall be cut into a

suitable size and stored in the vicinity of the site and it will be informed to the

Owner.

4) Prior clearing, wooden pegging which shows the clearance area will be

installed after inspection by the Owner on the clearance area.

5.2.2 Topsoil Removal

1) Basically, the topsoil including stumps and roots shall be removed and

disposed. Any suitable topsoil which is free from roots and vegetable matter

shall be stockpiled at the specified area and used for planting and/or

embankment. The specified area is to be informed to the Owner.

2) It seems that stumps are not deep and long considering the actual site

conditions, thus all of them can be basically removed and replaced with

suitable material. In case that it is difficult to remove all, its countermeasure

will be discussed with the Owner.

3) Removed topsoil which is suitable material for the construction will be stored at

suitable area along the road where it is distinguished in order to prevent mixing

with unsuitable soil.

4) Keeping clearance to the minimum area is required for the proposed project

activity. The extent of vegetation clearance at each site shall be surveyed and

clearly marked prior to the commencement of clearing. In case that the

existing paddy field is within project area, the ridge of paddy field is to be sifted

and irrigation canal shall be diverted.

8.3 Sub-Plan Detail for T3 Access Road - Environmental

SP01 Erosion and Sediment Control

The control of erosion and sedimentation will be carried out by side ditches and pipe culverts. Mitigation measures for erosion and sedimentation control of slope will include:

An open ditch will be constructed on both sides of the road T3 to divert and collect surface

run-off.

The location of pipe culverts can be referred to the drawing plan

Speed humps will be installed inside of side ditch at 50m intervals to reduce water velocity

during heavy rain periods, allowing sediment to be trapped within the side ditch.

In the case that overflow from side ditches occur the ditch size will be increased or modified

accordingly.

Silt fencing or similar materials may be used depending on site conditions or during the rainy

season.

Weekly inspection are conducted as part of the Contractors Environmental, Health and Safety procedures, and these will include inspections of side ditch and sediment traps. Any maintenance such as clearing of sediment will be at the inspector’s discretion, with frequency of clearing increasing during heavy rain periods.

SP02 Water Availability and Pollution Control Open ditches will be designed to allow water to be diverted, minimizing the potential for

uncontrolled run-off. By diverting turbid surface water run-off this will allow for maximum

infiltration.

All maintenance of excavation machinery shall be conducted at workshops to avoid any

storage of hazardous materials such as oil and fuels on site. The use of re-fueling trucks will

eliminate the need for any fuel to be stored on site.

If repairs need to be carried out on site, an oil pan needs to be used to collect any oil and

reduce spillage.

Temporary toilet/s will be provided on site and workers instructed to use these facilities.

SP03 Emission and Dust Control

Water spraying vehicle will be provided in active construction sites as necessary.

All vehicles, while parked on site, will be required to have their engines turned off.

All workers on the ground will be required to wear the correct PPE such as safety glasses,

ear plugs, and breathing masks if necessary.

Speed limits will be imposed to 25km/h or less for all vehicles to reduce dust along access

roads.

To avoid spillage, haul trucks must not over fill their load.


NNP1-MS-RW038-A1


SP06 Hazardous Material Management

All fuels for road works machinery and excavators are stored at worker camp sites in

specially designed areas.

Mobile re-fueling trucks will be used to reduce the need for fuels to be stored on site.

Discharge of any fuels or oils into the environment will be prohibited

8.4 Sub-Plan Detail for T3 Access Road - Social

SP04 Noise and Vibration

All construction personnel working within the construction area will be provided with hearing

protection if working in noisy condition, defined as greater than 80dBA.

SP13 Unexploded Ordinance (UXO) Survey and Disposal

UXO survey and disposal has been conducted by NNP1 prior to commencing any type of

Project related survey or construction activity.

If any UXO’s are uncovered during earthworks or construction of road T3, all works will stop

immediately and the Owner (NNP1) will be notified. No works will be allowed to resume

without approval from NNP1.

SP15 Traffic and access

Watchmen on the ground will control local traffic and ensure safety of excavators and earth

moving machines.

Regularly monitoring of traffic conditions will be conducted as part of the routine

Environmental, Health and Safety inspection.

Speed limit shall be 10km/h when passing along Project roads

Installation of notice boards near entrance of work site to inform workers and visitors of local

hazards and blasting schedule.

Haul trucks must not be overloaded with excavated material when being transported to

disposal areas


NNP1-MS-RW038-A1


SP16 Training and Awareness All new employees will be required to complete Induction Training from OC/NNP1 prior to

commencing any work on site.

In this training, the Contractor will highlight site regulation/rule, and safety & environmental

issue.
