About this file
This document is a technical architectural drawing (Sheet A-002) for a Naval Facilities Engineering Systems Command (NAVFAC) project focusing on air barrier details for an Inspection Station at Naval Station Norfolk in Cutler, Maine. The drawing provides comprehensive technical specifications for air barrier components and installation, including detailed sections and notes covering foundation, wall, roof, and penetration air barrier requirements.
The technical drawing includes floor plans, building sections, and wall sections with specific air barrier installation instructions. Key technical details include self-adhering membranes, concrete slab air barrier components, closed cell spray foam insulation, vapor barriers, and specific requirements for sealing roof, floor, and wall penetrations. The drawing is part of the P-347 Perimeter Security Improvements project, associated with contract number N40085-19-D-9008 T008, and dated for improvements on 2/26/25, with the most recent revision on 5/19/2025.

A. FOR AIR/MOISTURE BARRIER SYSTEM AND TESTING REQUIREMENTS,
REFER TO SPECIFICATION SECTION 07 27 10.00 10.
B. SEAL ALL ROOF, FLOOR AND WALL PENETRATIONS OR ANY RESIDUAL
OPENING WITH SPRAY FOAM INSULATION CONFORMING TO ASTM E84.
C. DRAWINGS ON THIS SHEET ARE FOR DIAGRAMMATIC PURPOSES ONLY.
D. SELF-ADHERING AIR BARRIER MUST EXTEND 6" AROUND ALL WALL
PENETRATIONS, OPENINGS AND LOCATIONS INDICATED TO SEAL JOINTS
BETWEEN AIR BARRIER MATERIALS.
E. ALL JOINTS AT OPENINGS, TRANSITIONS BETWEEN DIFFERENT MATERIALS
AND PENETRATIONS MUST BE SEALED AS INDICATED.
F. THE ENCLOSURE SURFACE AREAS LISTED ON THESE DRAWINGS ARE
APPROXIMATE FOR THE EXTERIOR WALL (INCLUDING FENESTRATION,
GLAZING, LOUVERS AND DOORS), ROOF AREA AND GROUND FLOOR SLAB.
THE SURFACE AREAS LISTED INCLUDES THE GROSS EXTERIOR SURFACE
OF THE ENCLOSURE AND NO DEDUCTIONS WERE MADE FOR WALL
PENETRATIONS, AIR INTAKES, EXHAUST LOUVERS, MAKE-UP AIR INTAKES,
PRESSURE RELIEF DAMPERS OR ANY OTHER INTENTIONAL HOLES. THIS IS
NOT INCLUDED IN THE AIR BARRIER DESIGN OR CONSTRUCTION.
FENESTRATION IS INCLUDED IN THE AIR BARRIER ENCLOSURE
CALCULATIONS. TESTING COMPANY MUST VERIFY THAT THE AREAS
LISTED MATCH AS-BUILT CONDITIONS AND THAT THE TOTAL SURFACE
AREA OF THE ENCLOSURE IS CORRECT.
