This document is an architectural drawing showing construction details for an addition to an existing building, dated as-built October 19, 1998. The drawing presents five elevation views and a roof design detail for a structural addition that includes a freezer box extension.

The roof design (Section A) utilizes a TJI joist roof system with 11-7/8" to 25" joists at 16" on-center, featuring EPDM roofing at 60 mils thick and a 3/4" deck. The addition incorporates a scupper system for maintenance access and includes a maintenance access opening measuring 1'-8" x 1'-2". The east, west, and south elevations illustrate the integration of the new freezer box structure with the existing building, showing a galvanized metal cap over the new CMU addition, drainage provisions, and venting requirements. Detail B provides specifications for the roofing assembly including 5/8" sheet rock substrate. Construction notes specify that the roof shall conform to live load requirements, a 5/8" sheet rock must be installed to the underside of trusses above the addition, and TJI represents a truss joist incorporated system. The drawing indicates flashing cutouts into the existing building and shows specific dimensional requirements throughout all elevation views, with scales noted as 1/8" = 1'-0" for most details.
