description: Building 400 is an “S” Structure designed and constructed 1954-1955 at what was then the Medina Base National Stockpile Site (NSS). The Medina Base was built by the Atomic Energy Commission and the Armed Forces Special Weapons Project 1954-55 as one of thirteen installations where nuclear weapons components were stored, maintained and assembled. The Medina Base was constructed during the second generation of these special weapons storage bases, which were commonly referred to as “Q” Areas. This designation was due to the requirement for personnel to have a “Q” level security clearance because of the secret nature of work that occurred at these areas. This Historic American Buildings Survey report was prepared as mitigation in accordance with a finding of adverse effect under Section 106 of the National Historic Preservation Act of 1966, and the subsequent Memorandum of Agreement. This finding was made in response to the proposed demolition of Building 400 due to its obsolete nature in regard to current building needs and requirements at the Lackland Training Annex, and the desire to remove it from Air Force inventory and the need for its maintenance and upkeep. Archival and other research for Building 400 was undertaken by Julian W. Adams, Senior Architectural Historian for Geo-Marine, Inc. Research was undertaken between the dates of September 20-26, 2005, both on-site at Lackland Air Force Base and the Lackland Training Annex, and during production of the document at Geo-Marine Inc., Plano, Texas. Primary materials (including original plans and Real Property Accountability Records) and several secondary sources (both published and unpublished reports) were used.
