The group said that its subsidiary Cavico Energy Construction had been awarded the approximately US$2.5M contract by the Ministry of Agriculture and Rural Development.
Da Ban dam is 26m high and 348m long, and was built in the 1980s as part of an irrigation project in the Ninh Hoa district, north of Khanh Hoa province.
