The Federal Reserve Board is executing a comprehensive renovation of two historic Washington, D.C., buildings: the Eccles Building (constructed 1935–1937) and the 1951 Constitution Avenue Building (constructed 1931–1933). Both structures are listed on the District of Columbia Inventory of Historic Sites, with the latter also on the National Register of Historic Places.
Project Goals
The renovation aims to modernize systems, improve safety, and consolidate operations, while preserving the historical and architectural integrity of both buildings. Key initiatives include:
-
Removal of hazardous materials like asbestos and lead.
-
Replacement of outdated systems, including electrical, plumbing, HVAC, and fire suppression.
-
Structural upgrades to meet current accessibility, safety, and security standards.
-
Restoration of historic features, such as marble façades, conference rooms, and original elevators.
-
Enhancements to public spaces along the National Mall.
Historical Significance
Both buildings played pivotal roles during World War II, hosting critical meetings such as the Arcadia Conference (1941–1942) and the Trident Conference (1943), where Allied military strategies were formulated. The 1951 Constitution Avenue Building also supported the Manhattan Project and later housed the Atomic Energy Commission and the National Science Foundation.
Project Oversight and Accountability
The project is overseen by the Board of Governors and the Office of Inspector General, with regular reporting to Congress. Extensive consultation has been conducted with federal and local agencies, including the National Capital Planning Commission and the Commission on Fine Arts, to ensure both preservation and compliance.
Procurement and Scope
Contracts have been competitively awarded across 32 U.S. states and D.C., sourcing materials such as structural steel, plumbing, and electrical systems nationally. The project consolidates Fed operations, reducing reliance on leased office space and lowering long-term costs.
Preservation Approach
Historic spaces like the Eccles Board Room and Octagon Room in the Constitution Avenue Building are being meticulously restored. Features removed during construction—lighting, wood panels, and flooring—will be reinstalled to maintain authenticity. Certain rooftop features and water elements were scaled back to manage costs and streamline construction.
