About this file
This document is a mechanical removals plan for Building 60 at Portsmouth Naval Shipyard in Kittery, Maine, prepared by Naval Facilities Engineering Systems Command (NAVFAC) Mid-Atlantic. The drawing (MD108) depicts the Second Floor Mezzanine and shows the locations and scope of mechanical equipment, ductwork, and piping to be removed as part of the B60 Repairs project (Project No. 1740579).
The general scope of work requires removal of all HVAC and industrial process equipment throughout the spaces shown, including air handling units, fans, controls, wiring, ductwork, hoods, and piping. Specific removals identified under CLIN 002 include industrial process exhaust and make-up air systems, ceiling fans with associated controls and wiring, and exhaust fans with associated ductwork, hoods, controls, and wiring. The mechanical subcontractor is responsible for identifying, making safe, cutting loose, and capping all items specified for demolition, while the general contractor shall be responsible for actual demolition and removal to an authorized salvage facility. Additional requirements include coordinating with architectural drawings for patching of floor, wall, and ceiling penetrations; coordinating removal with hazmat requirements; and conducting testing of the existing pumped steam condensate system return line back pressure, with results reported to the contracting officer prior to commencing removals. The drawing was finalized on October 1, 2025, with Amendment 008 dated March 10, 2026.
