PROPOSED LIBERTY HALL,EVERETT COMMUNITY COLLEGE _: Everett,Washington INTRODUCTION This report presents the results of our geotechnical engineering services for the proposed Liberty Hall at Everett Community College (EvCC) in Everett, Washington. The site is shown relative to surrounding physical features on the Vicinity Map, Figure 1 and the Site Plan, Figure 2. The general configuration of the proposed building is shown on Figure 2. Project Description We understand EvCC is planning to build Liberty Hall in the areas presently occupied by the Royal Motor Inn and Triangle parking lot located west of Broadway and south of the Student Health and Fitness Center. Our understanding of the project is based on discussions with SRG Partnership and EvCC. We understand the proposed 3-story building will encompass about 70,000 square feet. The footprint of the building will be about 190 feet by 210 feet in plan. The building program includes classrooms, labs for nursing and health sciences, and faculty offices. We understand the column loads will range up to 200 to 250 kips. Grading at the site will consist of cuts up to 9-feet deep in the western portion of the building footprint. Below grade walls are anticipated on the west end of the building. The project will seek a LEED silver or higher certification. Purpose and Scope The purpose of our services is to evaluate soil and groundwater conditions as a basis for developing design criteria for the geotechnical aspects of the proposed Liberty Hall. Field explorations and laboratory testing were performed to identify and evaluate subsurface conditions at the site in order to develop engineering recommendations for use in design of the project. Our services were performed in general accordance with our proposal dated March 5, 2010. Written authorization to proceed was provided by SRG Partnership on April 12, 2010. FIELD EXPLORATIONS AND LABORATORY TESTING Field Explorations Subsurface soil and groundwater conditions at the site were evaluated by drilling seven borings, designated B-1 to B-7, in the vicinity of theproposed building. The borings were completed to depths ranging from 24 to 311/2 feet below the existing ground surface using truck-mounted drilling equipment. The approximate locations of the borings are shown on the Site Plan,Figure 2. Details of the field exploration program and logs of the borings are presented in Appendix A. Laboratory Testing Soil samples were collected during drilling and taken to our laboratory for further evaluation. Selected samples were tested for the determination of moisture content, fines content (material passing the US. No. 200 sieve), and Atterberg limits. A description of the laboratory testing and the test results are presented in Appendix B. GEOENGINEERS. June 10,2010 ; Page 1 FOe No.5836-010.00
