1 INTRODUCTION

ANTRA Engineering & Consultancy Limited, founded by five civil engineers, started its

journey in 4th quarter of year 2009, to reach the target of providing quality and reliable

engineering solutions by means of

blending the experience of its founders

with the enthusiasm of breathing a new

life into the engineering market.

Producing tailor made solutions for

engineering problems requires existence

of high concentration, sound engineering

background and up-to-date know how of

all related disciplines involved. ANTRA's

mission in the contracts undertaken is

to search for state of the art

engineering practices for provision of technically reliable, sustainable and economical

engineering solutions. Sound cooperation established with the Clients, strong

communication abilities and devotion to corporate procedures are keys of ANTRA for

reaching to the targets set.

Since ANTRA founders have participated as

design engineer, project manager and

coordinator for more than 10 years in many

multi-national and large scale engineering

projects; ANTRA has high-level experience, on

contrary to the youtfulnness of the company, in

engineering and management of complex

international projects. Rising on this

experience, ANTRA contracted and compeleted

feasibilities, final and detailed designs for many

energy facilities. Among the completed/ongoing

projects till foundation of the company,

following can be listed:

preparation of feasbility, final design (including electrical and mechnical installations and hydromechanical design) and detailed design (including hydromechanical

design) for run-off river and storage type hydroelectric schemes, with both free

flow and pressurized conveyance lines,

design services for dams, small ponds and irrigation systems, geotechnical consultancy services and designs for ground improvement, various consultancies for checking structural/hydraulic design of various

engineering structures and for electromechanical and hydro-mechanical equipment

for hydropower schemes

2 FIELDS OF ACTIVITY

ANTRA, by basing on its background, is providing engineering and consultancy services

within the following fields:

Energy Facilities Dams and Weirs Infrastructure and Transportation Structures Geotechnical Engineering and Ground Improvement Planning and Development of Land and Water Reources

In addition to preparation of planning studies, feasibility reports, final design and detailed

(application) design, technical specifications, tender documents and carrying out

consultancy services during the tendering stage (selection of Contractors) in the above

fields; ANTRA is also providing services for preparation of loan application reports and due-

diligence reports especially for energy investments.

2.1 Energy Facilities

Although the services of ANTRA regarding energy facilities are mainly concentrated in

hydropower, its range is not limited to that and covers wind and thermal power plants as

well.

While serving in a wide spectrum in hydropower projects for determination of hydroelectric

potential of a site, dimensioning of structures and preparation of profitability analyses

(benefit/cost ratios, internal rate of return), preparation of feasibility and loan application

reports, final design and detailed design and provision of consultancy services for selection

of Contractors; ANTRA's scope for wind energy facilities are limited to detailed design

phase such as design of roads and auxiliary structures (culverts, bridges, etc.),

foundations for wind farms and structural designs of auxiliary structures. For thermal

power plants, ANTRA can provide detailed design engineering services for various

steel/reinforced concrete structures under the guidance of the final designer and full

designs for waste (ash or any other) storage dams, drainage and cooling water lines, etc.

2.2 Dams and Weirs

ANTRA has vast experience in the design of storage (dams) and diversion (weirs) facilities

which play an important role for use, control and management of water resources as per

requirements. In addition to dams and weirs constructed for the purpose of power

generation, there are various other dams and weirs constructed for domestic/industrial

water supply, irrigation, flood detention and waste storage in mining industry.

With a team of engineers specialized in computer aided analysis and design, ANTRA is

providing all engineering/consultancy services ranging from planning to commissioning for

5

concrete and fill (clay-core, CFRD and concrete face gravel dams, RCC) type of dams; for

concrete, gated and Tyrolean type of weirs and for both's auxiliary structures (spillway,

diversion tunnel/channel, cofferdams, sluiceways, etc.).

In projects where special design is required, ANTRA is capable of modelling dam,

appurtenant hydraulic structures and even the fluid (water) in 3D.

2.3 Geotechnical Engineering & Ground Improvement

Proper geotechnical and foundation design considering the loadings of construction and

operational phases of a facility are being carried out by ANTRA. Design of appropriate and

economical solutions for load bearing, settlement and seepage problems of

foundations/structures are designed by our experts.

Ground improvement techniques designed by ANTRA cover well-known and proven

supporting and reinforcing techniques such as piles, mini piles, ground anchors, stone

column and jet-grout.

2.4 Infrastructure & Transportation Structures

Increase of quality of life and sensitivity towards environmental issues raised expectations

and demands for urban infrastructure. Clean, healthy and abundant water supply &

distribution, and disposal of waste water, sewerage and solid wastes in an environmental

friendly manner are the most important of these demands. Transmission lines, city

reservoirs and distribution networks, waste water and storm water networks, pumping

stations, potable and waste water treatment plants constructed to meet modern urban

infrastructure requirements are among the facilities designed and supervised by ANTRA.

ANTRA is also performing designs for service roads, access roads and relocation roads,

bridges, tunnels and other appurtenant structures that may be required within the scope

of dam and weir projects carried out.

2.5 Land & Water Resources

Appropriate and sustainable management of land and water resources became more

important by global warming issue and increasing drought. Proper planning and

management of water and land resources can only be implemented by appropriate

planning of engineering facilities and taking into account the ecological demands.

With its staff specialized in the fields of water resources and hydraulic engineering, ANTRA

provides all engineering and consultancy services from reconnaissance study to

commissioning for all sort of power generation, irrigation, drainage, flood protection and

sediment control and water supply (covering facilities like pumping stations, treatment

plants, flood protection structures) projects aiming to develop land and water resources.

3 PROJECTS

ANTRA completed various final design, detailed design, due-diligence and feasibility

studies for more than 20 projects since its establishment and still continues to provide the

same for many other projects. Founders of ANTRA contributed as design engineer, deputy

project manager, project manager and coordinator for many internationally carried out

large scale engineering projects such as Ermenek Dam and HEPP Project (218 m high

double curvature thin arch dam, 300 MWe power plant, tunnel spillways, ~10 km long TBM

driven pressure tunnel) and Erik Weir and HEPP Scheme (as part of Ermenek Project),

Hakkari Dam and HEPP, Doanl Dam and HEPP and ukurca Dam and HEPP. In addition to these projects, many national scale projects such as Kkaksu Dam and HEPP (CFGD

body), Kale Dam (CFRD body), Aslanck Dam and Arkun Dam (CFRD body) were

contributed as well. ANTRA founders are also experienced on Indian Projects as they acted

as design coordinator/manager within international consortiums during the biddin stages

of Kishanganga HEPP Proejct, Pakal Dul Project, Tehri HE Pumped Storage Project, Lata

Tapovan HEPP, Rammam Stage III HEPP and Khasiyabara-Rupsiabagar HEPP Projects.

Majority of ANTRA's current portfolio is composed of final and detailed design works

carried out for private energy companies. In addition to these relatively long term

projects, short-duration consultancies and engineering services such as development of

alternative schemes, feasibility revision and preparation of due-diligence reports are also

forming ANTRA's business scope.

Within the short duration since establishment, national and international scale companies

like SKEN (skenderun Enerji), alk Enerji, Adal Holding, Yksel naat, Bereket Enerji, Ata naat, nal naat, Sargn naat and Energo-Pro tasted the service quality of ANTRA.
