406.5.2 uniform ventili on provided on 2 opposing sides require in 20%open ventilation. <br /> Sheets A3.1,A4.1 and A4.2 show openings and ventilation calculations. <br /> Egress: <br /> 2. This comment has not been completely addressed. Per the original comment,emergency egress <br /> lighting shall be provided at the following locations: <br /> a. Garage interior per IBC Section 1008.3.1. Clouded overhead lighting in garage,these have <br /> inverters for the emergency lighting. Added inverter emergency lights to legend. <br /> b.

The West Elevation 2/A4.1 shows a sloping finished grade that crosses through openings in the <br /> exterior wall. Sheets A1.1 and A3.1 show a retaining wall near the southwest corner of the building. <br /> The actual grade along the building should be shown, including the retaining wall. Note that the <br /> geometry of the retaining wall on Sheets A1.1 and A3.1 does not appear consistent with Sheets C1.0 <br /> and C2.0 of the civil drawing set. See IBC Section 107.2.1. Sheet A1.1,A3.1 and A4.1 revised <br /> elevation to show grade at building and revised architectural site plan and floor plans to match <br /> civil. <br /> 2. The South Elevation 1/A4.1 shows a sloping finished grade that crosses through openings in the <br /> exterior wall. Sheets A1.1 and A3.1 show a retaining wall near the southwest corner of the building. <br /> The actual grade along the building should be shown, including the retaining wall. Note that the <br /> location of the retaining wall on Sheets A1.1 and A3.1 does not appear consistent with Sheets C1.0 <br /> and C2.0 of the civil drawing set. See IBC Section 107.2.1. Sheets A1.1,A3.1 and A4.1 revised <br /> elevation to show grade at building edge and no grade conflict. Revised architectural site plan <br /> and floor plans to match civil. <br /> 3. Sheet A3.1 shows an MSE retaining wall at Grid G/7.3 abutting the exterior wall of the building. The <br /> exterior wall construction appears to be wood framing at this location. At a minimum,the end of <br /> the wood framing terminates near the face of the retaining wall, placing this material in close <br /> proximity with water and retained soils. The wood framing, structural sheathing, and siding and <br /> trim shall be constructed of naturally-durable or preservative-treated wood unless sufficient <br /> clearance between the retained soils and the wood is specified. Flashing should be provided to <br /> protected the wood from water seapage through the retaining wall. See IBC Sections 2304.12.1.2 <br /> and 2304.12.1.5. Sheets A3.1 and A4.1 moved MSE wall 15"to the west to avoid any added <br /> requirements as per IBC Sections 2304.12.1.2 and 2304.12.1.5. <br /> Structural <br /> See structural comments and responses from DCI Engineers, attached. <br /> Sincerely, <br /> (...._, 0 <br /> Charles E.
