Brief Description of the Project:

The Eastern Power and Electrical Co., Ltd. (EPEC) at Bang Bo, Samut Prakarn Province, is considering development of a natural gas fired combined cycle generating at Bang Bo in response to EGAT’s request for IPP Project. The power plant is 350 MW capacity which using natural gas and diesel oil as fuel.

a) The Environmental Impact Assessment (EIA) were found that air, noise and wastewater impact were minimize. The operation of power plant is not effect on ecology and social aspects. The migration measure and monitoring program were proposed for the power plant during construction and operation.

b) Geotechnical Engineering Design and Construction Supervision of Access Road and Site Preparation for Combined Cycle 350 MW Power Plant of EPEC at Bang Bo, Samut Prakarn Province. For Site Preparation works, the technique of Geotecxtile Bamboo Mattress as a ground improvement method has been employed to build a platform for embarkment and piling works for the Power Plant.

For Access Road and all service roads for the power plant the ground improvement using Menard’s Advanced Consolidation by Vacuum Technique combined with Controlled Modules Cement Columns (CMC) has been employed without high surcharging for preloading soils. At the end of 6 moths the ground was improved by around 1.8m consolidated settlement, i.e. 87% pre-consolidation was achieved.

K. Brief description of services:

(a) EIA

With SEATEC Group (Bangkok Engineering Services and Technology Co, Ltd.)

works including:

1) Project Coordination and management

2) Data collection and field surveys of environmental resources and value

3)Assessment of Environmental Impact and proposed mitigation measures and monitoring program.

(b) Geotechnical Engineering Design and Construction Supervision of Access Road and Site Preparation for Combined Cycle Power Plant Dynamic Engineering Consultants Co., Ltd. (DEC) took responsibilities:

1) Detailed Design and Supervision of Access Road (embarkment)

2) Overall Earth Work Design including all other scope e.g. internal road, water and water ponds, waste water out flow channel. Also perform supervision of construction of the works.

3) Supervision ground improvement work of site preparation and Access / Internal Road using geotecxtile-Bamboo Mattress method for site preparation and Vacuum

– CMC method for Access / Internal Road.

4) Reports preparation.
