s. It appears that there are existing columns in the basement that do not have foundation support that are shown in the proposed floor plan to remain in service. Please indicate where the existing footings occur on the drawings. 6. On 12/S2.1, it appears that there are missing welds from HSS stringbacks to the proposed plate assembly to the floor framing. In addition, the assumed soil pressure of 35 pcf noted on page C5 of the permit calculations indicates that the wall is intended to behave in the active soil pressure condition. The proposed strongbacks at the top of the wall appears to restrain this response, which may increase the soil pressures into an at -rest soil pressure condition. Please clarify the connection as well as that the soil pressure used as the basis of design. 7. Beam, B-4, appears to be overstressed by 20% for the design loading, but then indicates that adding (6) 2x10 beams over (5) 2x10 beams increases the capacity. Please indicate in the drawings how these beams are to be connected between each other for construction. 8. For the proposed collar tie indicated on Detail 8/S2.1, please provide design calculations validating the design of the member in sustained tension as this does not appear to be present in the permit calculations. 9. Detail B/A5.2 does not appear to have a foundation or stem wall indicated in the detail. Please clarify the foundation system used in this detail and depict it on the drawings. 10. Please provide diaphragm design calculations for the existing structure at each level indicating that the existing wall and floor diaphragms are able to withstand the forces transferred from the revised lateral load path. Architectural Review 1. The proposed window well as drawn does not appear to be capable of resisting design loads specified in the IRC. Provide window well details and section drawings as needed to show construction that meets minimum code requirements. 2. The energy code credit chosen (option 1c) requires the following components: -R-10 rigid insulation around the perimeter and under the entire slab -on -grade. Show the insulation in all section drawings where insulation is required (see Correction No. 9 above). -Below grade walls are required to be insulated with R-12 continuous rigid insulation on the interior and then a framed wall with minimum R-21 insulation is constructed on the interior of the rigid insulation. Please revise section drawing to reflect this requirement. The stairs in the basement of the easternmost dwelling will need adjustment to allow the required depth of insulation. The plans show that you selected option 5b, but the description and the credits shown are from option 5c. Please correct.
