2015 – Rehabilitation of Calueque Dam: Challenges and successes

P C Blersch, W van Wyk , R Steenkamp

Construction of the partially completed Calueque Dam on the Cunene River in Angola was abandoned in 1976 due to the hostilities in Angola. In 1988 the dam was bombed, causing significant damage to the bridge deck, other structures and equipment. Work to complete and rehabilitate the dam commenced in late 2012 and included major earthworks, extensive concrete repairs and refurbishment and installation of mechanical equipment, including ten spillway radial gates and two outlet gates with lifting equipment, emergency gates and cranes, including electrical and control systems. A number of challenges were encountered in planning and executing the project but were overcome largely as a result of detailed historical project information having been retained well beyond the norm and through the involvement of a key member of the original project team in the current project.
