This is an architectural floor plan for the Department of the Treasury, specifically depicting an elevation and floor layout for a federal building. The plan shows a symmetrical design with two central elevator/stair cores flanked by four corner stairwells with associated mechanical systems. The layout features two prominent vertical circulation shafts in the middle, each with elevator banks and adjacent mechanical spaces, positioned within a rectangular floor plate. The plan indicates restroom facilities, louvered vents for HVAC systems, and mail delivery stations distributed throughout the perimeter. Multiple exit doors are marked at strategic locations along the building envelope, ensuring compliance with life safety codes.

The drawing is designated as an Assembly Plan for Debt Building - Elevation Preliminary, prepared by the Department of the Treasury's Bureau of Engraving and Printing. The document includes a scale of 1/8" = 1'-0" and is numbered 1000027, indicating this is part of a larger set of architectural construction documents. The plan demonstrates standard federal building design practices with emphasis on vertical circulation efficiency, emergency egress requirements, and mechanical system integration for a multi-story office structure.
