Historic American Engineering Record

The legislative authority for Historic American Engineering Record (HAER) is the 1935 Historic Sites Act (Public Law 74-292) and the 1966 National Historic Preservation Act (Public Law 89-665), as amended in 1980 (Public Law 96-515).

The HAER program was founded in 1969 by the American Society of Civil Engineers, the Library of Congress, and the National Park Service after it became apparent that industrial and engineering resources demanded a different sort of interdisciplinary documentation approach from that applied to historic architecture. HAER sets out to capture vanishing industrial and engineering treasures nationwide. In the quarter century since its founding, HAER has accumulated documentation on over 4,500 historic industrial sites and structures representing a varied cross section of America's industrial and technological heritage. Each site is preserved on paper in written historical reports, large format photographs, and sets of drawings to capture the significant characteristics of the site. They are an outstanding resource for the American public.

The following reports, photographs, and drawings are the HAER record for the Rocky Flats Plant, covering its history and significant contributions from 1953 to 1992. Much of the early information came from current and former employees of the plant. Special thanks to Jack Weaver, Steve Cunningham, Tim McGrath, Kathy Abeyta, Patrick Ervin, and Patricia Powell.

A set of 17 drawings and a series of current and historic photographs illustrate the plant-overview report. The drawings delineate the geographic location of the Rocky Flats Plant; the Nuclear Weapons Complex; nuclear weapons production flow diagrams; the Cold War time line; the Rocky Flats Plant historic district; various production flow diagrams and building relationships; and health and safety, laboratory, and security aspects of the plant. The photographs depict the original construction, growth of the plant, the relationship of the buildings, and the setting. The individual building reports and photographs follow the plant photographs.

For specific information regarding processes, construction, and history of each structure considered, and contributing resources of the Rocky Flats Plant historic district, see the following documents.
