(AL-SI) completed an additional subsurface exploration <br /> progra�n at the subject properry to complete this addendum report. The purpose of this <br /> exploratory work was to provide additiona( information concerning the subsurface soil <br /> conditions in areas previously occupied by buildings during our previous field study. This <br /> information was then used to refine geotechnical engineering recommendations for foundation <br /> support for the proposed new building. This report also summarizes augercast pile design <br /> recommendations previously provided to the project structural engineer. Our findings and <br /> recommendations are oudined in the following sections of fliis letter. <br /> The site has been previously explored and studied by AESI. AESI's previous study was a <br /> report tided "Subsurface Exploration, Geologic Hazard, and Preliminary Geotechnical <br /> �ngineering Report — Everett School District Maintenance Facility" dated May 1, 2001. <br /> Information obtained during d�is previous study will be augmented by this current scope of <br /> work. <br /> T6is repoR preseuts d�e results of our additional subsurface explorations and geotechnical <br /> engineering study for Ihe proposed maintenance faciliry. The approximate locations of the <br /> explorations accomplished for this study and our previous study are presented on the revised <br /> ( Site and Exploration Plan, Figure 1.
