Wiles Mensch Corporation – DC (WM) provided civil engineering services for the construction of the new US Census Bureau Headquarters facility in Suitland, Maryland. This project was designed to accommodate the increasing need of space for Census Bureau employees. The project was built in two phases, and totals 1.5 M SF over 80 acres.

Phase I consisted of 771,000 SF of office building and parking garage space. Phase II consisted of 730,000 SF of office building and parking garage space. The buildings were designed to meet the criteria for GSA’s Design Excellence and Construction Excellence programs and to achieve the LEED Silver rating.

WM supported the project from master planning through construction, including the preparation of the site, utility, and grading plans. Coordination with county, state, and Federal Government review agencies, such as Maryland-National Capitol Park & Planning Commission, Maryland Department of the Environment, and the Washington Suburban Sanitary Commission, was necessary to obtain the required permitting and approvals for this plan.

The US Census Bureau Headquarters Office Complex was awarded an “On the Boards Citation” under the 2002 GSA Design Award program in recognition of the building’s innovative design and integrated approach to achieving the client’s goals and objectives, and proposing comprehensive solutions to complex and challenging requirements.
