David Pedersen Plan Check Number: B2205-005, First Building Review May 24, 2022 Structural 1. The project appears intended to include prefabricated roof trusses. See IRC Section R802.10. The following comments should be addressed: a. The design criteria for the trusses should be specified in the drawings. See Table R301.2(1) and EMC Section 16.01.010(J). b. The drawings should include a note specifying the following: i. The trusses should be designed by a professional engineer licensed in the state of Washington. ii. The truss construction drawings and calculations should bear the seal and signature of the engineer performing the design. iii. The truss design should be reviewed for conformance with the approved construction drawings and the referenced building codes and approved for construction by the designer-of-record for the approved drawings, prior to fabrication and erection. 2. Details for the construction of the stairs should be included. The joist spacing and spans should not exceed Table R507.6 considering a minimum 60 psf live load. Joists should be based on the net depth after notching for stairs. The minimum required dead load should be determined by the designer and stated in the design criteria. Sistered framing is recommended to control deflections for long spans; fasteners should be specified. See Sections R106.1.1 and R301.1. 3. A general fastener schedule should be provided per IRC Table R602.3(1). Providing a reference to this table in the drawings does not satisfy this requirement. In addition, the make and model of proprietary hardware should be specified where used for connections. 4. See Section 1 on Sheet 3. Drawings should show solid blocking between roof trusses above the braced wall panels in accordance with Figure R602.10.8.2(1). R602.10.8.2 5. The interior braced wall appears to not be continuous to the roof sheathing. A braced wall should be specified on the second story floor. BR602.10, R301.2.2.6 6. The portal frame design appears to not satisfy the minimum length requirements of Table R602.10.3(1) and R602.10.3(3) after applying the adjustment factors. The selected option in Table 2 on Sheet 3 specifies 1-story building but the project includes a 2-story building. 7. See wall bracing schedule on Sheet 3. It is not clear which option (A-F) is specified for BWP1. Plans should clearly state the intended wall bracing method. R602.10.4 8. See Section 1 on Sheet 3. The interior finish should be specified as a minimum 1/2"gypsum wall board. The gypsum wall board may be omitted provided that the required length of bracing is multiplied by the appropriate adjustment factors in Tables R602.10.3(2) and R602.10.3(4). R602.10.4.3 9. Drawings should include construction details of the stepped down footings.
