About this file
This document set contains architectural and engineering drawings for plumbing modifications at the KC-46A ADAL Maintenance Hangar (Building 254) located at Pease Air National Guard Base, New Hampshire. The project is being executed by TerraTech and includes detailed mechanical and plumbing plans for the mezzanine level.
The primary scope includes installation of new plumbing fixtures and systems within the mechanical mezzanine and existing restroom areas. Key work items encompass replacement of lavatories with new fixtures while retaining existing sinks and refinishing walls; replacement of shower heads and valves while maintaining the existing shower pan; installation of new compressed air piping (various diameters of CA lines); routing of chilled water (CW) piping at 100 PSI; installation of sanitary sewer piping with field location of existing services and tie-in to existing sanitary infrastructure; condensate drainage routed to floor drains; and gas (G) and stainless steel (SS) piping installations. The drawings specify equipment locations including PWP-1 (positioned over an existing C6 channel beam near grid line E'), hydro-pneumatic tanks, and various support infrastructure. Construction requirements include steel fabrication using A36 electrodes, paint preparation to match existing conditions, and proper removal of paint at weld areas prior to welding. The calculation sheet dated 10/13/2022 provides detailed layout specifications for support systems under the slab at PWP-1 and tank locations.
