including overstrength; see ASCE 7-16 Section 12.3.3.3. Alternatively, a prescriptive design complying with the prescriptive limits of the IRC is required. 3. The footing depth has been addressed. However, there are other issues with the foundation that should be addressed.The foundation reinforcement is not clear in the drawings and should be depicted to clarify the required placement. The slab should be reinforced. The reinforcement in the foundation does not appear adequate for the manufacturer's installation of the holdowns; see additional commentary above regarding holdown design. 4. This comment has not been addressed. The studs exceed the prescriptive limits of the IRC. An engineered design is required to substantiate the wall framing. The design should consider concurrent out-of-plane loading from wind with gravity loading. The stairs should not be considered to provide lateral support for the stairs. Additional Comments: 1. It appears that the building is intended to have gas appliances and equipment. Smoke and CO alarms should be provided per IRC Sections R314 and R315. A heat detector is required in the garage per Section R314.2.3. The locations of all alarms should be shown on the plans. A note should be included requiring the alarms to be hardwired, interconnected, and provided with back-up battery power as required. Alarm clearances should comply with Section R314.3 Item 4 and Section R314.3.1. 2. 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. c. The exterior walls will require stability bracing where the wall framing is not continuous from the foundation to the roof sheathing(i.e.,the exterior walls are topped with end trusses). Details and calculations for the bracing should be submitted for review. Note that the bracing is not designed by the truss manufacturer, nor is the truss stability bracing intended to address this requirement. Please contact me to schedule a meeting to discuss any questions. Thank you. — Drew Martin, P.E.,S.E.
