Cannon Renewal Project Overview

Cannon Renewal Project Overview

Cannon House Office Building 1908

The Cannon House Office Building, the oldest Congressional office building outside of the Capitol Building, is in need a complete renewal. The century-old building is plagued with serious safety, health, environmental and operational issues that are rapidly worsening. Without action, the essential systems housed behind the walls and in mechanical rooms will continue to crumble and fail, impacting Members, staff and constituents.

Need for Renewal

The Cannon Building has not received a comprehensive systems upgrade since the 1930s, and many of the building's systems are original – dating back to 1908 or earlier. The systems are past the end of their useful lives and the increasing risk of their failure jeopardizes the building's long-term functionality and safety. Other necessary work includes upgrading infrastructure systems andrepairing the exterior stone façade.

Cannon Renewal Project

The Cannon Renewal Project will provide an effective workplace for the next century to serve the needs of the U.S. House of Representatives and support Congressional operations.

The renewal process is scheduled to take approximately 10 years, with each of the five phases (0-4) aligned to fall between Congressional move cycles. Phases 1-4 of the project will require that affected wings of the building be vacated. Members and their staffs will remain in the upper campus, while some Committee and support staff will relocate to the Ford House Office Building or the O'Neill Federal Building.

Phase 0 is scheduled to begin after the 2014 election and will have a low impact on building occupants. This phase includes installing building utilities, primarily in the basement and the moat area of the courtyard. This phase enables future work to connect to the new systems, minimizing shutdowns and disturbances.

Phases 1-4 impact a quarter of the building, one side at a time, starting with the west wing in 2017 (New Jersey Avenue) followed by the north wing, east wing and concluding with the south wing. Members in the CHOB will not be relocated until December 2016 in advance of the Phase 1 construction. Construction activities are expected to take place during normal business hours, with the noisiest work activities occurring after business hours.
