The consultant was awarded the contract by Song Bung 4 Hydropower Management Board, which is part of Electricity of Viet Nam (EVN).
Song Bung 4 is under construction in Quang Nam province, and the 156MW project involves construction of an RCC dam, a 7.2m wide headrace tunnel, a 16m diameter surge shaft and a powerhouse (65m by 20m). The dam height was given as 114m and the headrace as 3.2km although previously the Asian Development Bank (ADB) has noted the dimensions as 110m and 3.1km, respectively.
Mott MacDonals said the contract on the US$267M project involves design reviews, technical advice and assistance with procurement, resettlement advice and monitoring, environmental management advice and monitoring, construction supervision and also knowledge transfer.
It added that the contract is under a programme funded by ADB. The bank recently approved a US$191M loan for the project, which is due to be completed over 2013-14. The balance of funds will be provided by EVN and the Viet Nam Development Bank.
