Ef1GIf1EER5 g Washington Oregon California September 6, 2018 Texas Alaska Charlie Morgan Jr. Colorado 7301 Beverly Lane g Montana Everett, WA 98203 The following structural comments are in response to the initial building permit review: 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': The architect confirmed the flow structure is "well away" from the nearest concrete foundation/retaining wall. 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. Proved redundancy does exist per ASCE 12.3.4.2 "a." in conjunction with table 12.3-3, see hand calculations under"lateral analysis design." 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. This is not applicable due to there being no torsional or extreme torsional irregularity (see comment 4). 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.
