Pre-inspection | Conduct pre-inspection in accordance with SWS 2.0100.4 Work Area Inspection and Stabilization Gaps, cracks, and holes in fire separations located within the work area will be visually identified and incorporated into air sealing work scope, including those that span two conditioned or unconditioned spaces Where drawings are available that identify specific fire-resistance ratings (i.e., 1 hour, 2 hour), materials and methods will be employed to preserve or restore such rating Where drawings are unavailable or do not identify specific fire-resistance ratings, the fire-resistance rating of the assembly may be inferred from the current construction (i.e., single 5/8 sheetrock, concrete masonry unit), and materials and methods employed will be consistent with restoring or preserving such inferred fire-resistance rating Repairs necessary to stabilize work areas and protect or preserve integrity of energy improvement will be completed before subject work begins | Provide a safe and stable work environment Repair moisture and structure-related issues |
