1. The minimum sone rating of 1.0 should be shown for the whole house fans. IMC Section 403.8.6.5 2. The requirements of WSEC C402.5.1.2 for testing of the air barrier should be shown on the plans. Structural 1. On Sheet S2.1 Grid 1/E and Sheet C4.1 in the Civil Drawing set, there is a "Flow Control Structure" with a rim elevation of 188.50 feet. The top of slab on this sheet is 181'-9". Please clarify if a site retaining wall is required at this location and if the opening shown in this area needs to revised or relocated based on the proposed rim elevation of the"Flow Control Structure". 2. It appears that the redundancy factor, p, of 1.0, per ASCE 7-10 12.3.4.2, was included in the design of the lateral systems in either the concrete or the wood portions of the structure. Please provide supporting calculations to verify that these lateral systems in both orthogonal directions meet the requirements of p = 1.0. Otherwise, please provide design calculations and revise the lateral design as required to satisfy the increase due to the redundancy factor, p =1.3. 3. Based on the use of the Equivalent Lateral Force procedure in ASCE 7-10 Sec 12.8. Please provide drift calculations to verify that the Torsional Amplification factor, Ax, does not need to be increased more than 1.0 per ASCE 7-10 12.8.4.3. 4. Please provide checks for structural irregularities for both structures concrete and wood portions per Tables 12.3-1 and 12.3-2 in ASCE 7-10. 5. Permit calculations for the concrete column design do not appear to include tie design check requirements per ACI 318-14 Sec 18.14.3. Please provide calculations and revise tie designs are required. 6. It appears that concrete dowel designs between PT slab to concrete shear wall elements are using a (p =0.75 rather than the (p-factor of 0.6 per ACI 318-14 Sec 21.2.4.2 as this would correspond to the 0.6 factor used in concrete shear wall designs calculations. Please revise dowel design as required. In order for the processing of your application to continue, it will be necessary to provide the Building Division with two new sets of revised construction documents reflecting the corrections requested. Please include a response letter which indicates how the corrections were resolved.
