Wiles Mensch Corporation – DC (WM) provided surveying and civil engineering services for the design of a new 140,000 SF facility, to serve as the permanent home for the International Spy Museum. The new innovative civic learning center features three levels of exhibit space, which rests on one level of retail, educational and lobby areas. The museum is topped with administrative offices and a large flexible space to accommodate specials events. The site of the museum is located on the high traffic, pedestrian friendly, L’Enfant Plaza.

WM completed a boundary, topographic, and utility survey as an existing conditions base for the design team. Survey-to-mark (STM) and ALTA/NSPS surveys were also completed for the project. The survey team also provided full-service subdivision, and full-service building plats. WM was responsible for the design of key site/civil features including grading, utility infrastructure, and stormwater management design. Due to the site’s adjacency to Federal property, extensive coordination with various local and Federal permitting agencies was required to obtain approval for the design.

The International Spy Museum was designed to achieve LEED Silver certification.
