Grunley serves as the design-build contractor for the HVAC retrofit of the Federal Deposit Insurance Corporations FDIC main headquarters building at 550 17th Street NW Washington DC. The project includes seven stories above ground a basement parking garage with two access ramps and a penthouse mechanical room. The 260000 square foot building has had several piecemeal updates over the years including installation of blast-resistant film on the windows replacement of the cooling towers and chillers build-out of the previous cafeteria and installa- tion of a new sprinkler system. Grunley completed the earlier renovations but this is the first large-scale modernization that has been performed. All of the existing HVAC systems will be replaced including ductwork the roof top unit RTU and variable air volume VAV boxes. The windows will be replaced while work proceeds on the renovation of the floors. Energy-efficient blast-resistant win- dows will be installed on floors two through six while the existing curtainwall on the first and seventh floors will be modified to receive energy-efficient laminated glazing. The three existing RTUs inside the penthouse will be replaced. As the building will be occupied during the construction a temporary air supply will be provided to the existing floors until they are switched over to the new HVAC system. We will upgrade the building one floor at a time. The project will seek LEED NC 2.0 Silver certification.
