SJRA Surface Water Facility

McCarthy served as the prime Construction Manager-at-Risk for San Jacinto River Authority's new Surface Water Facilities project. To supply raw water to the treatment plant, the project required construction of a marine intake structure and pump station approximately 300 feet out from the lake shore. Features include an 18,000-square foot pump building atop a concrete platform in 50-60-foot water depth supported entirely by 60-inch diameter drilled shafts. A new 40-foot wide, four-span pre-cast girder bridge provides access from the existing dam crest road to the structure.

McCarthy's self-perform work included all concrete work (except the drilled shafts), including the bridge and pump station concrete superstructures, furnishing and installation of pumps and process piping, as well as furnishing and installation of HVAC equipment and duct work.
