Main Floor Plan a. The upper floor is comprised of two sub -diaphragms. Please show how the new columns will effectively transfer lateral loads into the foundation. Response: A detail of the column was provided on sheet 4/20 in my July 31s, response. The column is acting as a simple vertical beam supported at the top by a CC connected to the roof framing and the bottom by the main floor diaphragm and steel floor and column framing. There are 4-3/4" bolts specified to attach the bottom of the beam to the steel framing and a CCOQ welded to the top of the HSS6x6 column that takes the load into the roof framing. All welding is to be %4' fillet unless noted otherwise. A note is to be added to the roof and floor framing that the floor/roof trusses in line with these columns are to be designed to transfer 2500 Lb. from the truss into the floor/roof diaphragms. See details attached. Sheet A-5 15. Guard Rail above the open areas. Response: This is a fabricated steel railing per the new detail and specifications provided. Posts will be bolted/welded to the steel beam below. Sheet A-6 19. Column numbers are shown on the attached key sheets. 20. Wood columns are multiple studs in walls. Walls to be attached to the Footings/Slabs with 5/8"x6" Titen Screws at the Required anchor bolt spacing. Strong Bolts or Titen Screws. 21. Steel columns are to be attached to the concrete with 4-5/8" Strong Bolts per the detail provided. ij p } �- 6 Z) -1 1 'l I 142 1, V J f' Henry Byam Response to Comments Dated January 5, 2016 February 16, 2016 Page 2 of 2 Sheet A-7 23. Steel to Steel are columns with cap plates bolted to the steel beams with 4-3/4" bolts per detail on S-2. Steel to Wood beams are Simpson CCO per detail on S-2. 24. Steel Column to top of Stem wall connection is the same as to footing with 4-5/8" x5" Strong Bolts or 5/8"x10" Anchor Bolts. 25. All beam Hangers are HWU Hangers matched to beam depth and height so beams flush with top of wood nailer. Hangers to be welded to steel beams per Simpson requirements. 8102 and B103 are to have %" Plates welded to steel beams and wood beams to be notched to fit in under top flange per detail attached. Sheet A-8 26. New 21.5' Column was detailed in July 31, 2015 comment response. This column extend from the main floor, across the upper floor extending to the roof. The bottom was to be bolted to the steel beam supporting the main floor to transfer the lateral load into the main floor diaphragm. The top was to have a bucket welded on to hold up the roof beam and transfer the lateral load into the roof diaphragm. Sheet A -9A 28. There are two locations that present this detail. Both are in T -walls and can be supported by different height wall studs as shown on attached. 29. There are no studs over 12' tall that are not braced by corners very close to them. Walls are broken up by horizontal continuous beams to take the wind to the wall corners. B65 and b66 are one continuous beam. General 41. Details are shown on the Lateral detail Sheet S-1. This should address all the items you asked me to address. If you have any further questions or I can be of any further assistance please call me at the above number. Rick Heide, P.E.

Shapiro Architects �,��ant o co FROM: Andrew Gahan, Plans Examiner RE: Plan Check: BLD2015-1320 Project: White SFR Project Address: 8545 Talbot Road During a review of the plans by the Building Division for the above noted project, it was found that the following information, clarifications, or changes are needed. A complete review cannot be performed until the revised plans/documents, including a written response indicating where the `clouded' or otherwise highlighted changes can be found on the revised plans, have been submitted to a Permit Coordinator. Reviews by other divisions, such as Planning, Engineering, or Fire, may result in additional comments. Note that the comnments from the original review appear below in italics. Original Non-structural: 1. Please clarify by what means the required energy credits from Table 406.2 of the 2012 Washington State Energy Code will be met. The information provided in your response must be added to the plans. 2. Clarify the method by which the whole house ventilation requirements will be met per the 2012 IRC section M150Z The information provided in your response must be added to the plans. 3.

OK Original Structural: 5. Main Floor Plan a. The upper floor is comprised of two sub -diaphragms. It is clear how the two sub- diaphragrn.s are transferring shear load on three sides and intennedia.tely. However, please clarify the shear path of the lateral load generated by the upper floor diaphragm along the interior halves of the aforementioned sub -diaphragms. Please show how the new columns will effectively transfer lateral loads into the foundation. Provide details of the connections required above, below and at the mid - span diaphragm along the columns. b. It appears that the sub -diaphragms comprising the upper floor do not conform to the aspect ratios provided in the AMPA SDPWS section 4.2.4. Please justify. OK c. Please provide calculations to show that the upper floor diaphragms are not overstressed without blocking. OK 6. Please provide framing layouts for the roof and floor framing from the manufacturer for each level of the structure with engineered lumber/trusses, as a deferred submittal.
