Bhutan, Dagana District - bt/13


The Dagachhu Hydro Power Corporation (DHPC) invites sealed bids, deadline 30th September, 2008, for design, build and completion of Lot I (civil works), consisting of engineering, procurement and construction of a diversion weir, connection channel and tunnel, desilter, shafts, powerhouse, maintenance and control buildings, water supply, sewerage and sewage treatment system, lighting and small power distribution system. The civil engineering component of the project is difficult due to extreme gradients and unstable slopes. Water from the Dagachhu is diverted by a small dam at an altitude of approx. 825 m above sea level through a short tunnel into the de-silting basin. From there, the water will flow through the main tunnel (approx. 7,700 m) and through the steel penstock (approx. 360 m) into the powerhouse.
