Section 1/A303 specifies use of pressure -treated sill plates for the walls. The following comment should be addressed: a. The section specifies a minimum clearance of 6 inches. However, the section and West Elevation 2/A204 indicate the clearance may be less than 6 inches, placing the vertical wall framing, sheathing, and siding less than the minimum clearance to exposed ground. Note that the existing grade slopes towards the west side of the building per Site Plan 1/A000, and foundation drains are not provided, which may result in the accumulation of sediment and water. The minimum clearance should be provided or the wall construction should use preservative -treated or naturally -durable wood. See IRC Section R317.1(5). b. South Elevation 1/A204 and Section 1/A304 indicate that the wall framing will be level with the driveway slab -on -grade. The vertical wall framing, sheathing, and siding are within the minimum 2-inch clearance. The minimum clearance should be provided or the wall construction should use preservative -treated or naturally -durable wood. See IRC Section R317.1(5). c. Cut ends of preservative -treated wood should be coated with a preservative treatment complying with AWPA M4. The requirement should be stated in the construction drawings. See IRC Section R317.1.1. 8. Section 1/A303 specifies a wall assembly that is presumed typical for the entire building. The following comments should be addressed: a. The design is presumed to comply with the continuous sheathing method of IRC Section R602.10.7.
