A federally owned building built in the 1930’s. It’s currently the HQ for Federal Bureau of Prisons (DOJ) and part of the National Historic Register. We performed our work in an occupied building, HVAC was provided to building occupants throughout the duration of contract. This project involved replacing an outdated and poorly functioning HVAC system, and the installation of blast resistant and thermal windows throughout an historic building.
The HVAC system modernization required the replacement of two chillers, three cooling towers, seven air handling units, all associated pumps and the installation of a new Building Automated System (BAS). This system was state of the art and was expected to provide significant energy savings for the next 30 years. The new blast windows and thermal windows also added to the mechanical system’s energy efficiency. The blast windows provided protection to federal government employees working in this building.
WBG provided operation security programs, progress management meetings, document control, submittal & request for information process, development of independent government estimates, inspection services (Coordination and Review), and project closeout. Results: WBG was on time and under budget. The Project had less than 4.5% change orders. Upon completion the project will net a return for the Treasury $1.2 million that was not spent.
