Mr. Brian Bodge <br /> Plan Check Number: B1901-029, First Building Review <br /> March 6, 2019 <br /> Geotechnical <br /> 1. The project does not appear to include a geotechnical investigation of the project site soils. <br /> Based on the location of the project site, the design soil load bearing values shall not <br /> exceed the presumptive values of Table 1806.2. The design values shall not exceed those <br /> for Class 5 materials without classification of the site soils or performance of a geotechnical <br /> investigation by a qualified geotechnical engineer. The allowable soil bearing strength shall <br /> not exceed 1,500 psf. The design of site retaining walls shall include active and hydrostatic <br /> pressures, seismic surcharge pressures, and traffic surcharge pressures per IBC Sections <br /> 1610.1, 1803.5.12 Item 1, and 1807.2.2. The design values shall be specified in the <br /> construction drawings. See IBC Sections 1603.1.6, 1603.1.8, 1803.1, 1803.5.1, 1803.5.2, <br /> and 1806.2. <br /> Architectural <br /> General: <br /> 1. Work on existing buildings shall comply with the IEBC. The IEBC provides three alternative <br /> methods for performing work: the Prescriptive Compliance Method (Section 301.1.1), the <br /> Work Area Method (301.1.2), and the Performance Compliance Method(301.1.3). The <br /> method selected for the project should be specified on Sheet T-1.0. A statement should be <br /> provided clarifying the types of work that are included in the project (e.g., repairs, <br /> additions, change of occupancy, etc.) and referencing the appropriate IEBC sections. The <br /> comments provided herein presume the project will comply with the Work Area Method of <br /> Chapter 5. Based on a review of the construction drawings, the proposed project appears <br /> to include the following work: Level 2 Alternations (Chapter 8) and Change of Occupancy <br /> (Chapter 10). Additional and alternative types of work required for the project shall be <br /> identified by the designer-of-record. Additional comments may be pending. See IBC <br /> Section 101.4.7 and IEBC Section 301.1. <br /> 2. The occupant load for each level of the building shall be stated in the construction drawings. <br /> Based on Occupancy Classifications"B"and"M"for the Main and Basement Levels, <br /> respectively, the respective occupant load factors per IBC Table 1004.1.2 are 100 and 60 <br /> applied to the gross floor areas. The estimate occupant load for each level is 10 and 19, <br /> respectively. The occupant loads shall be verified and stated in the construction drawings. <br /> See IEBC Section 106.2.1. <br /> Fire Protection: <br /> 3. The project includes a change of occupancy for the Basement Level from "B"to"M". This <br /> results increase in hazard for the exterior walls per IEBC Table 1012.6. The north wall has a <br /> separation of less than 10 feet with the adjacent building. Presuming that the adjacent <br /> building requires a minimum 5-foot fire separation distance to the imaginary lot line <br /> between the buildings, the fire separation distance for the building is less than 5 feet. <br /> Therefore, the north Basement Level wall shall be a minimum 2-hour wall per IBC Table <br /> 602. Details for the wall construction shall be submitted for review. The details shall <br /> reference listed assemblies substantiating the fire rating. <br /> V 3200 Cedar Street 0425.257.8800 O everettpw@everettwa.gov e <br /> Everett,WA 98201 425.257.8882 fax everettwa.gov 0 <br />
