A2.5.pdf

This is an architectural drawing document for wall types used in construction, specifically a reference sheet showing detailed wall assembly specifications for a federal building project.

The document presents multiple wall type configurations labeled L, M, N, O, J1, H0, H1, H2, H3, I1 through I9, and V2, each illustrating different interior and exterior wall construction methods. The wall types are classified by location (interior or exterior) and include detailed technical specifications for stud framing, insulation materials, vapor barriers, fire blocking, and finishing materials such as drywall board. General notes provide critical construction requirements including framing specifications (6-inch studs required), insulation installation guidelines, vapor barrier placement protocols, fire blocking mandates, electrical outlet routing instructions, and compression joint details. The specifications reference existing 5/8-inch plywood roof sheathing for certain applications and detail requirements for wall-mounted systems and acoustic insulation. The drawing is part of a larger architectural set for Ben Delson Jr./High School Phase 3 at Eielson Air Force Base in Alaska, prepared by USKH architecture firm. The reference number is A2.5, dated September 23, 1998, and indicates this is a standard construction specification sheet intended to establish uniform wall assembly standards throughout the project.
