C11"Y (),F EEXWO llw* Itemized below is our response to the review comments in the November 16, 2016 letter for the above referenced project. Our response appears in bold. Sheet 51.2 _ Schedules 27. Holdown Schedule a. Clarify on the plans the callout for the 'MSTM40' holdown. A corresponding strap tie with the indicated capacity could not be found in the manufacturer catalog/inventory. There was a typo in the holddown schedule. The holddown specified is a MSTCM40 concrete strap holddown. The holddown schedule has been updated and a new note has been added to the schedule to refer to detail 1/54.2 which shows the attachment of the holddown strap to the lower basement wall. We have also provided the sheet from the Simpson catalog for the holddown in the attached supplemental calculations for your reference. b. Provide on the plans the information for 'Note 4' referenced in the 'Anchor Bolt' column to guide proper review, construction, and inspection. The holddown is a strap that attaches to the lower basement concrete wall, therefore there are no anchor bolts used. The reference to "Note 4" has been removed, and the holddown table has been updated to show that there are no anchor bolts. Sheet 52.1 Notrndation Plan 28. Foundation Plan a. Clarify on the plans the callout for the middle 2'-0" diameter 6'-6" auger cast footing below the ends of the N -S oriented PT 6x14 HF#2 beams (beam 'D. FL. BM -3' on sheet '1.26' of the provided structural calculations) used to support the west end of the 'Patio' floor framing and below the west end of the roof framing ridge beam 250 4th Avenue South, Suite 200 Edmonds, WA 98020 ph. 425.778.8500 1 f. 425.778.5536 www.cgengineering.com 110 Sunset Remodel December 29, 2016 Structural Response #1 Page 2 of 3 (beam 'DR. BM -1' on sheet'1.7' of the provided structural calculations). It appears to be undersized for the loads noted at that location in the provided structural calculations. There was an error in the calculation of the required pole area on page 1.68 of the original structural calculations. This calculation has been updated and has been included in the attached supplemental calculations, and on sheet S2.1 and detail 1/S3.1. The new footing size is 2'-9" diameter x 6'-0" deep. b. Clarify on the plans the callout for the north -most 1'-9" x 1'9" x 10" deep isolated footing below the ends of the N -S oriented PT 6x10 HF#2 beams (beam 'D. FL. BM - 4' on sheet '1.26' of the provided structural calculations) used to support the 'Patio' floor framing. It appears to be undersized for the loads anticipated by the represented construction. The point load below the middle post of the roof framing ridge beams does not appear to have been accounted for. The point load below the middle post of the roof framing is picked up by R. HDR -4 and does not come down at that location, however that load was not accounted for in the south most 1'-9" x V- 9" x 10" deep isolated footing. This calculation has been updated and has been included in the attached supplemental calculations, and updated on sheet S2.1. Sheet S2.2 Main Floor ramie Pian 29. Main Floor Framing Plan a. Clarify on the plans the indicated location of work to be completed per detail callout '2/S4.2'. It does not appear to correspond to that anticipated at that location. This detail shows the 5-1/8" x 12 GLB framing into the PT 6x14 Beam. The section cut is shown correctly. However, the section cut for detail 1/S3.1 has been updated to be shown in the right direction. b. Clarify on the plans the callout for the 2x12 HF #2 joists (joist'D. FL. J-2' on sheet '1.26' of the provided structural calculations) to be used below the east -most portion of the 'Patio' at the entry to the structure. They appear to be over spanned and fail in bending. The joists specified on the plans appear to be different than those specified for that location in the provided structural calculations. The plan on sheet S2.2 has been updated to match what was shown in the structural calculations (Dbl. 2x12 HF#2 joists @ 16" OC). c. Indicate on the plans the required installation of a continuous 23 -foot 2 -inch multispan 6x10 DF#2 beam (beam 'MF. BM -7' on sheet'1.40' of the provided structural calculations) to be used as a girder to support the floor framing below'Banquet A. The use of three individual shorter beams results in beams that appear to be over spanned and that fail in bending. 250 4th Avenue South, Suite 200 Edmonds, WA 98020 ph. 425.778.8500 1 f. 425.778.5536 MWONEERING www.cgengineering.com 110 Sunset Remodel Structural Response #1 December 29, 2016 Page 3 of 3 A shorter beam has been checked and shown to be adequate. This calculation is included in the attached supplemental structural calculations. Indicate on the plans the required installation of a continuous 21 -foot 4 -inch multispan 6x10 DF#2 beam (beam `MF. BM -8' on sheet'1.40' of the provided structural calculations) to be used as a girder to support the floor framing below'Banquet B'. The use of three individual shorter beams results in beams that appear to be over spanned and that fail in bending. A shorter beam has been checked and shown to be adequate. This calculation is included in the attached supplemental structural calculations. Sheet S2.3 -- Ceilin Framin Plan. 30. Ceiling Framing Plan — Clarify on the plans the callout for the 4x10 HF #2 beam (beam 'R. HDR -3' on sheet '1.11' of the provided structural calculations) over the sliding glass door in the south wall of 'Banquet A'. It appears to be over spanned and fails in bending. The beam specified on the plans appears to be different than that specified for that location in the provided structural calculations. The plan on sheet S2.3 has been updated to match what was shown in the structural calculations (3-1/2" x 9-1/4" PSL Beam) If you have any questions or comments regarding the responses to this review please do not hesitate to call.
