Hoffmann Architects, an architectural and engineering firm specializing in the rehabilitation of building exteriors, has been selected by the architect of the Capitol to design the restoration of the U.S. Capitol Dome.
Hoffmann Architects has worked with the Architect of the Capitol (AOC) to investigate conditions at the cast iron Dome. Work has included master planning and pilot studies, leading to a phased restoration strategy. Phase I, interstitial space remediation, was completed concurrently with the master plan and included lead-based paint removal and investigation of cast iron defects.
This past fall, Hoffmann Architects was retained to validate, expand, and update the original construction documents. Every aspect of the project will be revisited and analyzed to reflect current code requirements, new energy efficiency mandates, and updated security requirements. Hoffmann Architects will also provide a review of the construction staging approach.
This landmark project aims to restore the Dome of the U.S. Capitol to its original 1865 glory, erasing years of damage caused by exposure to the elements.
Hoffmann Architects is honored to have been selected as the rehabilitation specialist for the protection and conservation of this symbol of American government, its values and ideals.
