M-112.4.pdf

This is a mechanical engineering drawing showing a partial ductwork and piping plan for the first floor (Phase 4) of Building 9, which appears to be part of a VA facility renovation project. The drawing (numbered M-112.4) details HVAC ductwork and sprinkler system layouts, including detailed piping routes, connection points, and mechanical equipment locations. The plan is part of bid documents for a fully sprinklered system and was prepared by Guidon Consulting for Miller-Reinick LLC, working with the Office of Construction and Facilities Management at the Department of Veterans Affairs.

The drawing includes general sheet notes and sheet keynotes providing specifications for the mechanical systems, and features a key plan showing the building's orientation. This technical document appears to be part of a larger set of construction documents for project #502-17-102, which involves replacing the roof and HVAC system in Building 9.
