Ms. Corrie Stark Plan Check Number: B2006-047, Second Building Review November 24, 2020 11. The type of the hot water system should be specified in the drawings per Section R306.4. Seismic restraints should be specified for tank water heaters per Section M1307.2. Structural 1. The construction drawings should include a section of structural notes specifying general requirements for the project. See IRC Table R301.2(1) and EMC Section 16.01.010(]). Standard requirements provided in this comment are based on IRC-based design criteria; criteria from other standards (e.g., ASCE 7-10, etc.) should be specified when used. The general requirements should include but are not limited to: a. Reference design standards and edition (e.g., 2015 AWC NDS). b. Gravity loads (e.g., live, snow, superimposed building weight, etc.). c. Snow design criteria. The design should consider a minimum snow load of 25 psf (EMC) unless an engineered design is performed per IRC Section 301.1.3. d. Wind design criteria. The design wind speed is Va,d=85mph (Vint=110mph) (EMC). The wind exposure category for the city of Everett is typically B, except for buildings located near open terrain or with unobstructed water views. See IRC Section R301.2.1.4 and Table R301.2.1.3. e. Weathering exposure. The weathering condition for the city of Everett is"moderate". f. Seismic design criteria. The Seismic Design Category is DZ (EMC). g. Specified material strengths (e.g., minimum concrete strengths per IRC Table R402.2, etc.), grades (e.g., all wood framing DFL #2 or better, etc.), and other general information for use in the structural construction (i.e,. all proprietary hardware specified in the drawings should be [fill in]-brand products or approved equal, etc.). 2. The exterior wall framing has been modified to remove existing openings and add new openings. Wall framing details complying with Section R602.3. Headers should comply with Section 602.7. King and jack studs should comply with Section R602.7.5. Alternatively, construction not complying with these sections should have an engineered design per Section R301.1.3 and IBC Chapter 16; calculations substantiating the design should be submitted for review. See Section R106.1.1. 3. Continuing with the previous comment, the exterior framed walls should be founded on decay- resistant sill plates located at least 8 inches above the exterior grade per Section R317.1(2). Wall framing not complying with this requirement, including sheathing and siding, should be decay-resistant materials per Item (5). 4. Framing plans for the existing roof construction should be submitted for review. The framing should comply with Section R802.5 and Table R802.5.1(5). Collar ties should be provided as needed per Section R802.3.1. Braces and bearing partitions should be provided as needed per Section R802.5.1. The framings should have uplift resistance per Section R802.11. Alternatively, trusses should be substantiated per R802.10 and R802.10.2, or an engineering evaluation should be performed per Section R301.1.3 and IBC Chapter 16; calculations substantiating the design should be submitted for review. See Section 106.1.1. 5. Framing plans for the existing ceiling construction should be submitted for review. The framing should comply with Section R802.4 and Table R802.4(1) or R802.4(2).
