Project Details

ACECO was hired by the Clark-Christman Joint Venture to provide demolition, shoring, abatement, and excavation services in the efforts to renovate the Cannon House Office Building (CHOB) which is controlled by The Architect of the Capitol. Located on Capitol Hill, The CHOB is the oldest Congressional office building besides the Capitol Building. This is a 4-phase renewal project in which ACECO has had and will have the pleasure of working on all phases as well as the preparatory phase 0.

The current Phase 3 focuses on the East wing along First Street. The East Wing requires selective interior demolition of the ground floor through 4th floor, structural demolition of the 5th floor and roof, and asbestos abatement. Historical preservation and design changes are the biggest challenges on this project. With the careful efforts of both our day and night shift crews and ACECO’s historic appreciation, we have been able to navigate the demolition activities safely while preserving the history of the building. Built in 1908, the building has seen many minor renovations and changes to design. With the assistance of the Clark-Christman Joint Venture, ACECO has tackled any design changes while maintaining the schedule and production.
