CONSTRUCTION HISTORY IN ARCHITECTURAL CONSERVATION: THE EXPOSED AGGREGATE, REINFORCED CONCRETE OF MERIDIAN HILL PARK
Meridian Hill Park in Washington, D.C., constructed 1915–36, is currently undergoing a long-term restoration plan for both its landscape and concrete elements under the direction of the National Park Service, the administrator of the park. Research was undertaken to document the construction history of the exposed aggregate, reinforced concrete work in order to guide future restoration work. Historical documents, including construction records, photographs, contemporaneous articles, organizational files, and correspondence, were consulted to develop the construction history. An on-site survey of the park provided further documentation of the construction history as evidenced in the physical fabric of the park. The research and on-site survey focused on the construction of the perimeter walls at Meridian Hill Park, as all major phases of experimentation and dissemination of the developed techniques took place there.
