The U.S. Army Corps of Engineers (USACE), Pittsburgh District, has a project to provide new steel upper machinery housings for the Gantry Crane hoists at Conemaugh Lake. Construction includes removal of existing housing to floor line, fabrication and installation of new housing (steel fabrication), removal of portions of steel diamond plate flooring and replacement with open grating, installation of floor hatches for access by personnel and access to the limit switches and replacement of electrical conduit, wiring and lighting. The upper machinery houses for the main hoists on the Gantry Cranes at Conemaugh Dam are extensively corroded and exhibit heavy loss on the housing steel (supports and steel plate cladding). The deterioration of the housing is allowing water to affect the hoist electrical and mechanical equipment. The flooring and access hatches are obsolete and allow vermin to habit within the housing which causes impacts to access the limit switches. The North American Industrial Classification Code (NAICS) is 237990 – Other Heavy and Civil Engineering Construction. The Small Business Size Standard is $45,000,000.00.
