Description: GPI provided mechanical, electrical, plumbing, and fire protection engineering services for this design/bid/build project at the 840,000 sq ft William J. Green Federal Building. The design team was selected under GSA’s Design Excellence program. The site houses 13 federal agencies, including the Federal Bureau of Investigation, Internal Revenue Service, Drug Enforcement Administration, and Department of Homeland Security. The scope includes an extensive overhaul to provide more efficient layout and an overall modernization of the building including renovating the conference center, fitness center, and cafeteria. As a part of the renovation/restack the electrical and HVAC distribution systems was replaced in their entirety to improve energy efficiency and comfort. In addition, significant portions of the building central plant was replaced, including chillers, cooling towers, electrical infrastructure, and emergency power distribution. The project offered an array of challenges attributed to programming, phasing, and budget with each agency having separate needs and requirements for maintaining a seamless transition during the phases of development. The building remained at nearly full occupancy during the renovation stage, along with several agencies that operate on a 24/7 basis.
