About this file
This is a mechanical ductwork plan drawing for a construction project at West Roxbury VA Medical Center in West Roxbury, Massachusetts. The drawing is part of bid documents issued for construction on November 14, 2025, and represents Phase 3, Area A of a boiler replacement and controls upgrade project. The drawing number is MH121.3A, with project number 0506-0012, prepared by Miller-Remick LLC Consultants as the Engineer of Record.
The mezzanine level ductwork plan depicts HVAC distribution systems including multiple air handling units (8-ACU-1 and 8-ACU-2), variable air volume boxes (5-VAV-07 through 5-VAV-12), and ductwork with various dimensions ranging from 6 inches to 32 inches. The plan shows exhaust and return air configurations, combustion air and boiler stack locations, and CFM (cubic feet per minute) specifications for individual terminal units. Key rooms identified include a boiler room, electrical room, IT room, corridors, lockers, shower facilities, and bedroom spaces. The drawing references related mechanical drawings (M-001 general notes, MP500 series details, MP600 series flow diagrams, and M-700 series schedules) and includes one addendum dated March 2, 2026. The scale is 1/4 inch equals 1 foot, and contractors are instructed not to scale the drawing but to verify all dimensions and clearances in the field.
