U.S. Capitol Exterior Preservation Project FAQs

Why is part of the Capitol Building covered in scaffolding?
The Architect of the Capitol (AOC) is preserving the building's exterior stone and metals. The project will prevent water infiltration, slow deterioration of the stone and corrosion of the metals, repair damage and remove soil and stains.

What is the purpose of the project?
The project is designed to prolong the life expectancy and preserve the historic features of the building. The project cleans, repairs and preserves the historic stone on Senate Extension and connecting corridor and the architectural metal throughout the building.

Why is the project starting now?
Previous surveying identified this project as critical and delaying this preservation would cause the building to deteriorate further and more of the U.S. Capitol Building’s historic fabric would be lost.

What are the benefits of the project?
This project will preserve the stone and architectural metals of the building and allow it to continue to function as the home of the United States Congress, the symbol of our democracy and for the enjoyment and education of future generations of Americans.

What will the Capitol look like during constructions?
The project will require scaffolding to execute the work. At night the scaffold and building will be lighted to assist workers as they perform their tasks. A scrim will cover the scaffolding to control dust and water spray.

What are the impacts of this project on visitors and staff?
To minimize the disruption to Congressional business, much of the project work will be performed at night, Monday through Saturday. Quiet tasks will be conducted during daytime hours. The windows will be screened to maintain privacy and safety during the project. Most doors will remain open for both entry and exit, while others will be for exiting only. 

Will the rest of the Capitol Building be covered in scaffolding?
Future phases of this project will cover different portions of the building with scaffolding.

How can we ensure the project delivers good value to the taxpayer?
The authorized budget for this phase of the project is $16.6 million.

The AOC is committed to maximizing taxpayer value. Following full and open competitive bidding, a highly qualified contractor was selected to perform the project. The AOC will maintain close oversight to ensure the project quality is the highest possible, the project remains on time, within budget, and minimizes disruption to the work of Congress.
