This Federal Office Building and Post Office was originally constructed in 1965 and, at the time, provided the only available space in Pierre for various agencies of the United States. CDC teamed with Sheehy, RSA and Harmon to deliver a turnkey design/build recladding for the General Services Administration Region 8 (GSA). This facade replacement was funded by the ARRA, and bid, designed, and executed within a 24-month schedule on an occupied building. The new curtain wall was designed to reduce the building's total energy consumption by more than 20% and placed the building into the high-performance green building category
