City of Redwood City Redwood Shores Branch Library PROJECT TEAM Fred Brovold, G.E., Senior Project Engineer, will be the project geotechnical manager. C. Barry Butler, P.E., G.E., Senior Principal Geotechnical Engineer, will provide our internal quality assurance review for this project. Fred and Barry will be supported by other members of our professional and administrative staff. SCOPE OF GEOTECHNICAL SERVICES Our detailed scope of services is presented below. File Review and Geologic Site Reconnaissance We will review previous information for the site and other projects in the site area to obtain geotechnical information and data applicable to the site and planned development. We will also perform a visual reconnaissance of the site and vicinity for evidence of site features indicative of potential geologic hazards. "Your work went extraordinary Field Exploration well and you came through in a lurch brilliantly." The revised building locations are outside City of Santa Clara the area where our previous boring was drilled for our preliminary geotechnical investigation. We therefore propose to further characterize the subsurface conditions with a conventional rotary-wash boring in the south building area, a cone penetration test in the north building area, and two shallow (15 feet deep) hollow-stem-auger borings in the parking areas. CPTs provide a nearly continuous subsurface profile, which can be used to estimate soil types and engineering properties and ground liquefaction potential. We will obtain relatively undisturbed soil samples from our conventional borings for visual classification and laboratory testing, as necessary. We will also obtain bulk samples from our lS-foot-deep borings for R-value testing and to evaluate pavement thickness requirements. We will mark the boring and CPT locations and notify you and Underground Service Alert (USA) prior to beginning fieldwork so that public or private underground utilities can be identified. We will also apply for drilling permit with the County of San Mateo. For the purpose of this agreement, it is the responsibility of utility owners to mark their utilities. We are not responsible for utilities not properly marked at the ground surface. To reduce the risk of damaging unidentified underground utilities during drilling, we will also contract with a private utility locator. Borings and the CPT will be permitted and backfilled with cement grout in accordance with San Mateo County guidelines. This proposal specifically excludes the assessment of environmental characteristics, particularly those involving hazardous substances at the site.
