Conduct pre-inspection in accordance with SWS 2.0100.4 Work Area Inspection and Stabilization
Where applicable (generally above-grade concrete slabs between conditioned and unconditioned spaces), 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
Where applicable, for assembly type and geographic location, test for radon per
