The dam package was awarded at Rs. 596.99 crore, HRT package at Rs. 343.11 crore, power house package at Rs. 315.64 crore, hydro-mechanical package at Rs. 242-34 crore, E&M works at Rs. 593.80 crore and transmission package at Rs. 548.97 crore.
In a meeting with the Central Electricity Authority, the project officials apprised the authority the current status of the project. In the dam package, being executed by Jaiprakash Associates, the diversion tunnel is nearing completion and river diversion is planned for June 2013. In HRT package, being executed by Gammon India, out of five adits, two adits have been excavated and HRT excavation has started from these two adits. In the power house package, being executed by Jaiprakash Associates, main access tunnel has been completed and excavation of power house cavern has started. The excavation of surge shaft is expected to start soon. Work on other fronts such as adits and tail race tunnels are in progress.
