Mr. Randy Heltne Everett Housing Authority Plan Check Number: B1807-032, Second Review October 17, 2018 14.This comment has not been completely addressed. See IBC Sections 107.2.1, 1603.1, 1604.1, 1613.1, and 2306.1, ASCE 7-10 Chapter 30, and AWC SDPWS-15 Section 3.4.1. The following comments shall be addressed: a. The overframing design on Sheet A-7 is incomplete. The required construction of the overframing is unclear; see Comment 13 for additional information. The west end of the west-most ridge member may bear directly on the sheathing; blocking shall be provided at the load points as needed. The structural design shall be reviewed and revised as needed. b. Calculation page 6 appears to indicate that the existing single 2x8 joists are overstressed and shall be doubled. The framing plans do not indicate double framing at the roof joists. 15. No additional comment. 16. No additional comment. 17. No additional comment. 18.This comment has not been completely addressed. The floor framing plan on Sheet A-4 specifies a new steel beam at the existing exterior east wall. See IBC Sections 107.2.1, 1603.1, 1604.1 The following comments shall be addressed: a. This comment has not been addressed. The calculations do not include an additional 15 psf partition load per IBC Section 1607.5. The beam design should be revised. b. No additional comment. c. The plan appears to specify the south post as a 5 1/8x5 1/4 while the north post is a 5 1/4 —square. Verify the required post size. d. Verify that Detail 5/S4.2 provides the end support condition for the W12 beam. The detail shall be referenced in the framing plans. e. Continuing with Comment 18d, the following should be addressed for Detail 5/S4.2: i. Verify if stiffener plates should be provided for the W12 bottom flange. These may be required if the beam does not directly bear on the post. Note that stiffeners may still be required if the beam bears directly on the post. ii. Verify the connection capacity, including bolt bearing, if the beam does not directly bear on the post. Calculations substantiating the capacity shall be submitted for review. iii. Vertical-slotted holes shall be provided in the connection plates if the beam is intended to transfer loads through direct bearing on the post. 19.This comment has not been completely addressed. The following comments shall be addressed for the headers shown in the floor and roof framing plans on Sheets A-2, A-4 and A- 7, respectively: a. The south wall header shall be specified.
