Bolivia reissues call for underground construction of 80-MW Misicuni

Bolivia utility Empresa Nacional de Electricidad (ENDE) has reissued a solicitation for underground construction work at the 80-MW Misicuni multi-purpose hydroelectric project on Bolivia’s Misicuni River. Bids are due September 20.

ENDE issued its original call for underground construction work bids by April 21. It took bids in June for surface construction at the project. In July it awarded contracts to supply a penstock and steel surge shaft liner, and to supervise construction.

The multi-purpose project, already under way, includes Misicuni Dam and a diversion tunnel, which is to deliver water from the Misicuni River through mountains to the Cochabamba Valley for Cochabamba municipal water supply and irrigation of 15,000 acres.

In the current solicitation, ENDE seeks bids for construction of underground works of the power project including: a tunnel extension of 706 meters; construction of supports and anchors to support the penstock over 1,428 meters; a transition pressure pipe of 3 meters; a 150-meter surge shaft; civil works of the valve chamber; and construction of an exit portal.

The reissued solicitation reduces the amount of time for the work to 18 months from 19. It also increases the budget for the work to US$7.4 million from US$6.9 million.
