Project Details
Owner: U.S. Department of Treasury
Contract Amount: $122,568,820
Date of Award: February 1999
Final Completion: March 1, 2006
Architect: Shalom Baranes Associates, Washington, DC
Grunley Construction, in a joint venture with Turner Construction, began a four-phased complete renovation of the U.S. Department of Treasury Main Building in February 1999. A National Historic Landmark, this building was originally designed between 1839-1842 by Robert Mills, the architect of the Washington Monument and the Old Patent Office Building. Subsequent additions were completed in 1861, 1864, and 1869; the Attic story, now the Treasury Building's fifth floor, was added in 1910.
The scope of the project included:
- A new heating, ventilation, and air conditioning system;
- A new electrical distribution system;
- A new state-of-the-art communication and data system;
- Fire/life safety upgrades, including fire alarm and sprinkler systems and improvements to provide emergency egress;
- A new plumbing system, including new plumbing fixtures; and
- Modifications for compliance with ADA requirements.
Key elements of this project included the concealment of MEP and life safety systems while preserving the building's historic fabric, causing minimal disruption to existing building elements, repairing and restoring existing damaged and deteriorated finishes and completing all work with minimal disruptions to Treasury operations.
Being located adjacent to the White House required that all operations be conducted within a highly secure environment. All deliveries, utility shutdowns, access to occupied areas, etc. needed to be scheduled several days in advance, and all workers were required to obtain security clearances prior to obtaining access to the building.
In 2002 the project won the "AEGIS" Award for Overall Jobsite Safety - General Contractor from the DC Metropolitan Subcontractors Association. In 2003, it won an AIA Award of Excellence in Historic Resources from the Washington Chapter of the American Institute of Architects (AIA). In 2006 it won Honorable Mention in the AGC Washington Contractor Awards. Most recently, the project won a 2007 Award of Excellence as Best Renovation - Urban, Over 150,000 SF from the MD/DC Chapter of the National Association of Industrial & Office Properties and was named as "Renovation Project of the Year" by Mid-Atlantic Construction.
