About this file
This is a mechanical ductwork plan drawing for the West Roxbury VA Medical Center in West Roxbury, Massachusetts. The drawing, designated MH131.3A, depicts the upper mezzanine level ductwork layout for Phase 3, Area A of the "Replace Boilers and Upgrade Controls" project. The document is part of the bid documents issued for construction as of November 14, 2025, with an addendum dated March 2, 2026. The project number is 0506-0012, and the drawing was prepared by Miller-Remick LLC Consultants as the Engineer of Record, with architectural and civil engineering by MABBETT & ASSOCIATES, fire and life safety by KOFFEL ASSOCIATES, electronic security by GRW, tunnel structural and civil engineering by PEC, physical security by FORCE PROTECT, and hazardous materials by WBRC.
The drawing illustrates ductwork configurations including 24-inch diameter boiler exhaust stacks extending through the roof, multiple 32x32-inch ducts for supply and return air, 4-inch combustion air and exhaust ducts, and a 14x12-inch duct running to the upper mezzanine level. The plan references multiple related drawing series (M-001 for general notes, MP500 for details, MP600 for flow diagrams, and M-700 for schedules) and notes that contractors must verify all dimensions, clearances, and as-built conditions in the field rather than scaling the drawing. The plan encompasses the area between the existing boiler plant, new boiler plant, and tunnel connecting to Building 1.
