This is a technical drawing document showing infrastructure plans for Building A-4504 at Andrews Air Force Base, Maryland. The document contains multiple engineering views including an installation photograph, a site location map, a building plan view, a plumbing schematic elevation, and a domestic water backflow device detail. The drawings are dated 06/15/2004 and reference Drawing Number BF-1 as part of a plumbing drawing series (Sheet 01 of 01).

The technical plans illustrate the layout of Building A-4504, which appears to be a multi-unit residential or barracks facility with numerous individual units arranged in rows. The document includes specifications for water and sewer infrastructure, a typical elevation of an Apollo reduced pressure principle backflow device (Serial Model Sheet No. A-1001-J), and plumbing details for a domestic water backflow prevention system. The site location map identifies Building A-4504's position within the broader Andrews AFB facility. This document serves as design and construction reference material for water and sanitation infrastructure work at the installation, with the project reference number MF# 079605.
