E 5. Section 1/A303 should specify a continuous #4 reinforcing bar at the top and bottom of the foundation. The bars should be specified as minimum Fy=40ksi steel. The section should specify a minimum cover of 3 inches. See IRC Sections R403.1.3.3, R403.1.3.5.1, and R403.1.3.5.3. Response: Additional rebar added, notes added. 6. Section 1/A303 should specify minimum %-inch bolts with a minimum 7-inch embedment per IRC Section R403.1.6. The bolt spacing should not exceed 6 feet, and provide at least two bolts in each wall panel section located not more than 12 inches from the end of the sill plates. The bolts should include 3-inch washers per Sections R403.1.6.1(1) and R602.11.1. Anchor hardware should specify corrosion protection per Section R317.3.1. Response: Foundation Plan added to set (sheet A101) showing anchor bolt locations & specifications Walls: 7. 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). Response: The design has been revised to double pressure -treated sill plate and pressure -treated sheathing. The siding is fiber cement. 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). Response: See response to #7a. 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. Response: Noted on Foundation Plan (newsheetA101) 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. The drawings should specify this as the typical construction, or the braced wall lines on each side of the building should be designated. See IRC Sections R106.1.1, R602.10.1, and R602.10.7. Response: Noted as "typicar
