1.4. Architectural Decorative Art

This decorative art is part of the fabric of a structure, permanently attached to the structure or building systems, or designed as part of an architectural space. Decorative art ranges from objects of great craftsmanship and historical importance to mass-produced objects. Often the name of the designer or maker is unknown. Conservation treatment may be appropriate for the highest level of decorative art. Approximate numbers are based on the Capitol Superintendent’s CAFM inventory, and will be refined based on the U.S. Capitol Building Preservation Guide, completed in FY 2014. Only about a third of the lighting fixtures are historic and considered heritage assets appropriate for restoration. The more utilitarian fixtures are at times moved or replaced.

1.5. Architectural Features

Historic architectural features include woodwork, shutters, columns, capitals, brackets, historic floors (e.g., the U.S. Capitol’s Minton tile floors) and special architectural surfaces (e.g., marble and scagliola). The Capitol Superintendent (or the Senate Sergeant at Arms) maintains these assets. While an accurate count of these features does not exist, the numbers are large. For example, there are at least 450 interior columns and pilasters with carved capitals. In recent years, special attention has been paid to the restoration of historic scagliola.

2. Capitol Grounds

The Capitol Grounds cover approximately 290 acres on which the U.S. Capitol, Senate and House Office Buildings and Capitol Power Plant reside. The Grounds include sculpture and monuments and living assets such as trees and plantings. Heritage assets include such elements as ornamental fountains, drinking fountains, outdoor seating, stone retaining walls and light fixtures.
