Wiles Mensch Corporation – DC (WM) provided surveying and civil engineering services for the modernization of the National Geographic Society Headquarters in Washington, DC. The project served to improve the public, visitor, and employee experience, by designing within the context of the urban environment and incorporating innovative features to revitalize the existing community. The design-build project included renovations to the campus grounds, courtyard, and existing building facades to create a cohesive campus identity. Revitalization of the urban campus aimed to unify the diverse collection of buildings on the site, which ranged from 20 to 100 years old.

The WM survey team provided boundary, topographic, and utility surveys, as well as an ALTA/ NSPS survey and Survey to Mark (STM). Civil scope included EIF coordination, traffic control plans, dry utility engineering, and construction administration. A site plan was provided referencing the schematic level external features of the site, including walkways, driveways, plazas, streetscape and other open spaces. WM was responsible for completing a review of the Stormwater Management installation for the Engineer’s As-built Certification. WM staff visited the site to provide an initial inspection of the stormwater management facilities, in order to confirm the as-built information as provided by the Contractor.

As a historic site, the project required approval from the Historic Preservation Review Board (HPRB), the Advisory Neighborhood Commission (ANC) & the DuPont Conservancy. The National Geographic Society Headquarters was the first project to be certified under the LEED for Existing Buildings (LEED-EB) rating system.
