Overview

Originally constructed in 1869, the U.S. Treasury Department’s headquarters building contained basic infrastructure not updated since the early 1900s and had also suffered from fire in 1996. The renovation was performed in four phases to minimize disruption to Treasury staff.

We provided structural design services to Shalom Baranes Associates for the seven-year modernization of historic building.

Highlights

  • Our scope consisted of structural evaluation, design, full-scale load testing, and construction administration to support office space enhancements, design of new stairs and egresses to meet fire/life safety requirements, MEP upgrades that included replacement of the chiller and cooling tower, installation of new elevators, and restoration of architecturally and historically significant aspects of the building.
  • The project also includes the removal of columns and design of full-perimeter underpinning to accommodate an electrical switchgear and transformer room.
