Mr. Ismail Mohammad 2713 Maple Street, LLC Plan Check Number: B2101-051, Second Building Review February 10, 2022 Structural The proposed project includes structural work. The overlay of structural information on the architectural plans is not sufficient to specify the proposed structural work. In addition, the framing appears to be incomplete, including but not limited to the area around the stairs at the Second Floor. The construction of the new interior and exterior walls, foundations, and stair landings is not included. Structural drawing should be submitted that include framing plans, sections, details, construction schedules, fastening schedules, materials requirements, general notes, special inspection requirements, etc. The drawings should substantiate compliance with the prescriptive requirements of the IRC. Alternatively, an engineered design may be performed for portions of the structural design per Section R301.1.3. See Sections R106.1.1 and R301.1. 2. 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. 3. Details for the construction of the new walls should be included. The details should specify connections for the top and bottom framing plates to the existing structure. See IRC Sections R106.1.1 and R301.1. 4. The proposed design includes modifications to the existing wall bracing. The drawings should be revised to show the modified wall construction. The braced wall lengths should be specified. See IRC Section R106.1.3. 5. The new and modified bearing and braced walls require new foundations. Details for the foundations should be included in the construction drawings. Anchorage is required per Sections R403.1.6 and R602.11.1. See Sections R403 and R404. 6. Framing details for openings in the walls including headers, and king and jamb studs, should be included in the construction drawings. See Section R602.7 and R602.7.5. 7. Continuing with the previous two comments, it is presumed that the braced walls and foundation anchors will comply with the prescriptive limits of the IRC. If an engineered design is performed for the anchors per Section R301.1.3, hold-down and shear anchor designs are required per ACI 318-14 Sections 17.2.3.4.3 and 17.2.3.5.3, respectively. The holdown design should include vertical seismic effects per ASCE 7-10 Section 12.4.2.2. See IBC Sections 1604.1, 1604.4, 1613.1, and 1901.2. 8. The Main Level wood sill plates and floor sleepers in contact with concrete are required to be preservative -treated or naturally -durable materials per Section R317.1 Item 3. 9. Wood framed construction should specify a minimum clearance of 6 inches and 2 inches above exposed earth and impervious surfaces, respectively, per Section R317.1 Item 5. 3200 Cedar Street © 425.257.8810 O everetteps@everettwa.gov Everett, WA 98201 425.257.8857 fax everettwa.gov/permits Page 5 of 6
