Original 1930 Steam Drawing for Reference.pdf

This is a technical architectural drawing depicting a basement plan with duplex vacuum pump systems. The document is dated 1930 and serves as a reference drawing for an original building's mechanical systems.

The drawing shows the layout and piping configuration for dual vacuum pumps located in the basement, with detailed annotations regarding system components and modifications. Key elements highlighted in red include notes on water storage capacity, pump removal status, capped lines, and components no longer in place. The plan identifies specific equipment such as the 1" non-return trap, 28" strainer, pump oil catch basin, P.V. steam line, and connections to various traps throughout the building. Section B-B provides additional detail on the vacuum return system configuration. The drawing references related steam and return line continuations shown on a basement plan and indicates that the vacuum system is currently used for a package connection from a trench. The document is marked as drawing number 2-7-2-048 from "Total Direct Radiation 999" and is drawn to a scale of 8"=1'0". This appears to be a historical facility documentation or reference drawing rather than a solicitation document requiring contractor response.
