Geotech was engaged as Principal Contractor for the Yallourn Weir Upgrade project. Geotech designed, constructed and installed a 30m long steel cofferdam in order to undertake the removal of the existing steel drum gate and construct a new concrete spillway whilst maintaining full water supply level. The project was made challenging because of the lack of existing and historical data from when the dam was originally constructed in the 1920’s and again during the two previous upgrades in the 1950’s.
An innovative steel A-frame temporary cofferdam was designed, constructed, installed and commissioned by Geotech after preliminary dive investigations were performed. This cofferdam enabled full supply of the weir during all construction works, ensuring the power plant would not go off line during construction works.
