4 <br /> ENGINEERING <br /> PUBLIC SERVICES DEPARTMENT <br /> Structural <br /> General: <br /> 1. Structural and geotechnical special inspections are required for this project. A statement on <br /> special inspections is provided in Note 13 "Special Inspection" of the Structural General Notes <br /> on Sheet S1.0. The statement shall include a table listing each type of special inspection and <br /> shall specify the extent of each inspection (e.g., continuous, periodic) per IBC Section <br /> 1704.3.1. The table shall include special requirements for seismic and wind resisting systems <br /> as required by IBC Sections 1704.3.2 and 1704.3.3, respectively. See IBC Sections 107.1, <br /> 1704.2.3 and 1704.3. <br /> 2. Note 15 "Concrete" of the Structural General Notes on Sheet S1.0 specifies a concrete strength <br /> less than 4,500 psi. The project appears to include concrete elements that are exposed to <br /> freeze-thaw cycles, and qualify as Class F2 concrete per ACI 318-14 Table 19.3.1.1. Per ACI <br /> 318-14 Table 19.3.2.1, the minimum concrete strengths for Class F2 concrete is 4,500 psi. The <br /> minimum concrete strength on Sheet S1.0 should be revised as required. See IBC Section <br /> 1901.2. <br /> 3. The Second Floor Framing Plan on Sheet S2.2 references Section 3/S4.2 along the interior <br /> double walls. The section shows the joists parallel to the wall while the plan shows the joists <br /> perpendicular to the wall. The section or the reference should be revised. See IBC Section <br /> 107.2.1. <br /> Gravity System: <br /> 4. The Second Floor Framing Plan on Sheet S2.2 appears to be missing floor joists at the top and <br /> bottom of the stair landings. The plan should be reviewed and revised as needed. See IBC <br /> Section 1603.1. <br /> 5. Sheet S2.2 shows Type B5 glulam beams at the middle of the units. The center and east units <br /> do not appear to include post supports at the west ends of the beam per Sheet S2.1. The <br /> design should be reviewed and revised as needed. See IBC Section 1603.1. <br /> 6. The south wall of the Third Floor on Sheet S2.3 appears to be missing headers at the double <br /> windows. See the the Front Elevation on Sheet A3.1 for clarity. Also, the post between the <br /> double windows should be specified. The plan should be reviewed and revised as needed. <br /> See IBC Section 107.2.1. <br /> 7. Sheet S2.4 shows Type RB1 glulam beams at the middle of the units. The beams do not <br /> appear to have post supports at the west ends per Sheet S2.3. The design should be reviewed <br /> and revised as needed. See IBC Section 1603.1. <br /> cjofICITY OF EVERETT • 3200 Cedar Street • Everett, WA 98201 • (425) 257-8810 • Fax (425) 257- <br />
