• • Ms. Finsch Tiscareno Associates Plan Check Number: B1801-032, First Review March 13, 2018 c. The design load appears less than the forces resulting from the terrace area between Grids S-7 and S-10. Additional documentation on the design loads should be submitted for review. See also other comments regarding the terrace loads. See IBC Section 1604.1 d. The last beam at each end of the structure supports perpendicular framing at Level 4 and should be evaluated for additional loads. See IBC Section 1604.1. 25. Sheets S210a and S210b show PSL5-1/4 beams supporting the Level 4 walls and roof above. The spans at multiple locations exceed the 14'-8"design length considered on structural calculation page SC137. Calculations substantiating the beams for the increased lengths should be submitted for review. See IBC Section 1604.2. 26. Sheets S210a and S210b include a cantilever roof along Grid S-A/S-5 — S-S.1-2.1. The following comments should be addressed: a. Structural calculations pages SC136 and SC139 for the 4x10 and 2x10, respectively, consider a backspan of 10 feet. The backspan is 6 feet per the drawings. The calculations should be revised. See IBC Section 1604.2. b. The grade for the 2x10 is DFL #1. This material is not included in the schedule in the Wood Framing"section of the Structural General Notes on Sheet S003. See IBC Section 107.2.1 c. Calculations do not appear included for the support beams under the cantilever beams and should be submitted for review. See IBC Section 1604.1. d. Calculations do not appear included for the connections between the cantilever beams and the beam providing hold-down resistance, and the hold-down beam and the walls. Calculations and details for the connections should be submitted for review. It is recommended that the stability of the back-span consider Equation 16-10 with a 0.6-factor on the resisting weight (i.e., floor). See IBC Section 107.2.1 and 1604.1. 27. Sheet S210b shows a cantilevering roof structure at Grid S-A—S-A.6/S.1-2.1 — S.1-3. The following comments should be addressed: a. The framing appears incomplete and should be revised. See IBC Section 1603.1. b. The sizes for multiple beams and joists do not appear to be provided and should be specified. See IBC Section 1603.1. c. Calculations for the framing and connections in this area should be submitted for review. d. It is recommended that the stability of the back-spans consider Equation 16-10 with a 0.6- factor on the resisting weight (i.e., floor). 28. Sheets S208a, S208b, S209a, and S209b show single TJI210 framing at 12-inch spacing with nominal spans of 16 feet or greater at multiple locations. Structural calculation page SC144 requires two pieces of TJI210 at 16-inch spacing, or an effective spacing of 8 inches, for spans not exceeding 15'-8". Alternatively, page SC145 allows two pieces at 12-inch spacing. Calculations substantiating the single pieces for the spans and spacing shown should be submitted for review, or the drawings should be revised to match one of the configurations specified in the calculations. See IBC Section 1603.1 and 1604.2. 29.The floor plans for Levels 2, 3, 4, and the roof, specify the typical headers to be two 2x8 framing. The headers at multiple locations support perpendicular floor joists and roof trusses. 6of11 CITY OF EVERETT • 3200 Cedar Street • Everett,WA 98201 • (425) 257-8810 • Fax(425) 257-8857
