Mr. Larry Thibeault Plan Check Number: B2111-005, First Building Review April 7, 2021 3. The building is required to have braced walls complying with IRC Section R602.10. The construction requirements of the braced walls, including anchorage to the foundations, should be included in the drawings. Note that connections to existing foundations using post-installed concrete anchors will require an engineered design. The locations of the braced walls should be specified in the plans. See Section R106.1.3. 4. Foundations should comply with IRC Chapter 4. Details should be provided. The foundations should comply with the minimum frost depth requirements. Note that the foundation against the existing building foundation may not comply with prescriptive requirements and require an engineered design per Section R301.1.3. The new foundations should not undermine the existing foundations. 5. Wood-framed construction on foundations should comply with Section R317.1, including clearance per Item 5. 6. The new garage is anticipated to be a concrete slab-on-grade. The construction should be specified. The slab should be sloped towards the door per Section R309.1. 7. Details for the construction of the new walls should be included. The details should include connections for the top and bottom framing plates to the supporting structure. See Sections R106.1.1, R301.1, and R602. 8. The Addition Framing Plan on Sheet A-5 specifying 9.5"TJI joists. The joist specification is incomplete. In addition, the joists are required to support a minimum 60 psf live load per Table R301.5 in addition to dead loading. Documentation substantiating the joist capacities should be submitted for review. See Sections R106.1.1 and R301.1. 9. Details for the construction of the stairs should be included. The joist spacing and spans should not exceed Table R302.3.1(2) considering a minimum 40 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. 10. Details for the design of the guards should be included. Calculations should be submitted for review. The guards, connections to the supporting framing, and the supporting framing, should be designed for a minimum 200-pound load per Table R301.5. See Sections R106.1.1 and R301.1. 11. The construction drawings should specify coating cuts, notches, and holes in preservative- treated wood with a treatment complying with AWPA M4.
