410 • A <br /> Mr. Art Skotdal ' <br /> Skotdal Real Estate <br /> Plan Check Number: B1906-031, Second Building Review - Structural <br /> October 18, 2019 <br /> Geotechnical <br /> 1. No additional comment. <br /> Architectural <br /> Architectural comments issued in the first structural review letter will be addressed in the second <br /> architectural review as needed. No additional architectural comments are provided herein. <br /> Structural <br /> General: <br /> 1. No additional comment. <br /> 2. This comment has not been completely addressed. The original comment stated that the <br /> geotechnical design parameters shall be specified in Section 01004"Geotechnical Investigation" <br /> of the Structural Notes on Sheet S1.01. See IBC Sections 107.2.1 and 1603.1.6.The following <br /> comments shall be addressed: <br /> a. The active pressure is specified as 35 pcf. This value corresponds to an unrestrained wall <br /> condition. See Figure 3 of the geotechnical report. The design shall be based on a <br /> minimum value of 55 pcf for unrestrained walls. Note that this appears to be the value <br /> used in the supplemental structural calculations. <br /> b. Continuing with the previous comment, the shoring system is temporary per the <br /> geotechnical report, and therefore the basement walls must be designed for full soil loads. <br /> Furthermore, Section 14 of the geotechnical report states that the basement walls should be <br /> designed with the same pressures used for the shoring systems. Figure 4 specifies the <br /> active soil pressures at deeper walls where two rows of tiebacks are provided. This criteria <br /> shall be specified and used for the design of the walls where recommended by the <br /> geotechnical engineer. The structural design may need to be revised. See additional <br /> comments below. <br /> c. The seismic, traffic, and building surcharges shall also be specified. <br /> 3. This comment has not been completely addressed. Section 01005"Required Submittal <br /> Procedures"includes the list of deferred submittals. See IBC Sections 107.2.1, 107.3.4, <br /> 107.3.4.1, and 107.4. The following comments shall be addressed: <br /> a. The note shall include a statement requiring the engineer-of-record to review the deferred <br /> submittals and verify conformance with the construction documents. <br /> b. The list includes ground improvements and prefabricated steel plate wood trusses. These <br /> items does not appear to be included in the project scope and shall be removed. <br /> c. No additional comment. <br /> d.
