Vietnam hydro plant builder Cavico Corp. has won a fifth construction contract for the 75-MW Dambri hydroelectric project, agreeing to build a rolling weir in 30 months.
Cavico said the US$3.12 million contract, to its Cavico Infrastructure unit, brings its total awards for Dambri to more than US$37 million. (HNN 1/31/08)
The rolling weir is to measure 55 meters high by 214 meters long.
In January, Southern Hydropower Joint Stock Co. awarded Cavico a US$19.2 million contract to build a second section of headrace tunnel for Dambri, in Vietnam’s Lam Dong Province. The tunnel segment is to be two miles long and 12 to 14 feet wide.
Earlier Cavico received a US$11.3 million contract for the first section of the tunnel, a 3.1-mile segment of similar diameter to connect the water intake and the pressure shaft for Dambri. Last year, Cavico received a US$3.75 million contract for a 12-mile access and service road.
Southern Hydropower broke ground January 22 on the US$80 million project, 87 miles northeast of Ho Chi Minh City at Da Huoai. Work is expected to be complete in 2010, generating 338 million kWh annually for the national grid.
