On Sheet 2/A300 and 4/S200, it appears that CMU walls are present from site photos along <br /> the west elevation. However,existing 2x4 exterior studs are being called out. Please <br /> clarify. Also, CMU wall construction appears to be new, please provide calculations <br /> addressing the design of the wall for gravity and out-of-plane lateral forces. <br /> 25. On 4/S200, CMU walls appear to be new and installed as part of the bearing wall system of <br /> the structure, please provide details and calculations addressing out-of-plane wall <br /> anchorage connections to brace the wall per ASCE 7-10 Sec 12.11.2.1. <br /> 26.The LVL ridge beam size shown on 2/S100 does not match the size shown on the permit <br /> calculations (R1 Beam).

Also, <br /> please identify which shear walls the full length drag strut.is"dragging" load to as it <br /> appears that no shear walls are directly connected to shear wall parallel to the drag strut <br /> line depicted. Please clarify. <br /> 29. On 1/S100, the new 2'-0"square footings provided do not meet the minimum steel ratio of <br /> Pmin = 0.0018 per ACI 318-14, Table 24.4.3.2. Please revise and update as required. <br /> 30. On 1/S100, there appears to be ex joists spanning to new beams (7 x 91 PSLs).
