The District of Columbia Department of General Services ("Department" or "DGS") is issuing this Request for Proposals to a construction manager to demolish an existing prefabricated one-story building located on the site at 2750 South Capitol Street, SE, Washington, DC 20032 and construct a new salt storage facility on that location. The Project will require the construction of a new 7,500 ton capacity salt storage facility that is approximately 54 feet wide by 204 feet long and 37 feet tall. The Project will also include an adjacent one-story storage structure with bathroom facilities. This adjacent structure will also house a 20,000 gallon capacity brine storage tank. ISTUDIO Architects has been selected at the designer for the Project, and must be substantially complete no later than August 30, 2016.
