19 Lower Level Mech.PDF

The image is a detailed architectural floor plan for the Target Materials Center (ALTR) Lower Level Mechanical drawing, prepared by the U.S. Army Engineer Division. The blueprint shows a complex, grid-based layout with numerous rooms, zones, and areas, including some sections marked as "NOT EXCAVATED". The document appears to be a record drawing, microfilmed, with technical grid lines, room annotations, and structural details across a large, comprehensive floor plan. The drawing is marked with revision information, contract details, and a standard architectural grid system for precise spatial mapping.
