Russell Rotunda Preservation and Fire Protection Project

Scaffolding for the Russell Rotunda Preservation and Fire Protection Project

The Architect of the Capitol is currently installing a new automatic fire sprinkler system in the Russell Senate Office Building, adjacent to the Kennedy Caucus Room and the Russell Rotunda. 

During the installation, the AOC will utilize the opportunity to preserve architectural features throughout this space in the Russell Building. Historic preservation efforts include repairs to ornamental plaster, gilding and stone cleaning around the third floor of the Rotunda and foyer area near the Kennedy Caucus Room. This area of the project is scheduled to be complete in spring 2014 and scaffolding will be removed upon its completion.

The next areas to be repaired are the Carriage Entrance followed by the 4th floor of the Rotunda.

Updated March 2014.
