Dome Restoration Project Updates

Update: January 2015

Scaffoldin​g and Restoring Phase
The Dome Restoration Project team is currently working behind the large containment area to remove lead paint and apply primer before repairing the cracks. As additional containment areas are mounted, the Architect of the Capitol is now using a new fabric to reduce the possibility of tearing during installation that can be caused by high wind gusts. This new material has a pink hue and will be used for most of the remaining containment areas, except near the top of the Dome where the plastic material would be better suited for enclosure at that location.

Construction task lighting is visible on the Capitol Dome in support of the Dome Restoration Project. The 720 LED construction task lights are installed to help workers as they restore the Dome at night.

Dome Restoration Project​ Mobilization

In support of the Dome Restoration trucks deliver equipment and supplies to the East and West Fronts of the U.S. Capitol. These deliveries occur between 6 a.m. and 3 p.m. Flagmen direct pedestrians to use the sidewalk during the delivery process for safety. If a pedestrian is unable to use the alternate sidewalk due to the need for wheelchair accessibility or other accommodation, then the flagmen will direct the truck traffic to stop and allow the pedestrian to safely pass on the sidewalk. Additionally, a staging area has been established on the northwest lawn of the U.S. Capitol for the duration of the project.
 
The plan below shows the truck route (red), the pedestrian route during deliveries (blue) and the staging area (yellow).
