Wiles Mensch Corporation – DC (WM) provided civil engineering services for the renovation of Constitution Center in Southwest Washington, DC. The modernization included gutting of the existing concrete shell originally completed in 1969, for replacement with an energy-efficient glass facade. This project proved challenging due to its uniquely large size, as the existing building occupied an entire city block.

WM provided a full scope of civil engineering design services for the project. Specific tasks included design for sanitary and storm connections, grading, and new fire service connection. Additionally, WM assisted the client and design team in preparing exhibits for WMATA’s right of way and in coordinating with PEPCO in regards to the existing ductbank requiring relocation.

WM also participated in the Preliminary Design Review Meeting (PDRM), and provided sketches creating illustrative sections through each street for DDOT and CFA review to depict artistic and technical competence. WM staff also responded to RFIs for the project.

The project received LEED Gold Certification.
