WBCM designed and coordinated window replacements and pre-cast concrete repairs for the United States Postal Service Headquarters building in Washington, DC. The building is a 14-story, 850,000 square-foot building with 480 windows containing 2,200 lite of glass. The design had to meet stringent requirements for construction due to the highly visible nature of the building.
WBCM detailed the replacement of existing single-pane glass with one-inch, insulating, low E glass. The replacement resulted in significant energy savings for the building.
WBCM designed extensive pre-cast concrete panel repair that included approximately 64,000 linear feet of joint sealant replacement, 185 locations of spall and crack repair, 360 linear feet of soffit panel crack repair, and 1,020 linear feet of balustrades removal and replacement. The repairs resulted in a more environmentally protected, weather-resistant building envelope.
WBCM incorporated considerations for construction worker and public user safety in the construction documents. Overhead protection and construction operations safety measures were included at the building entrances and noise regulations were imposed relating to the pre-cast concrete repair. All windows were replaced from inside the building, which required extensive coordination with USPS employees.
WBCM was responsible for the coordination of required consultations with the National Capital Planning Commission and the Chief Building Inspector for the Washington, DC Permits Division.
