Granite Construction Incorporated has been awarded a $72 million contract by the US Army Corps of Engineers (USACE) to build new outlet structures at the Addicks and Barker Dams in Houston, Texas.
Granite will be responsible for the construction of new intake towers, steel-lined conduits, parabolic chute slabs, stilling basins, cutoff walls and downstream filters, in addition to the grouting and decommissioning of the existing outlet structures in place at both dams. There will also be an additional seepage cutoff wall at Barker Dam.
Construction is scheduled to begin by the end of 2015. Following completion of the new structures, the temporary cofferdams will be removed and the site restored. Completion of the project is scheduled for May 2019.
