r <br /> City of Everett <br /> do Murray Smith and Associates <br /> August 10, 2007 <br /> Page 2 <br /> b. Trenching and temporary excavation techniques; including shoring, temporary slopes, <br /> and pipe support. <br /> c. Discussion of geologic and seismic hazards associated with the site, including <br /> recommended mitigation measures,if needed. <br /> d. Recommendations for foundation support including bearing capacity and expected <br /> settlement at the lift station location. Lateral earth pressures and backfill requirements <br /> for the lift station structure and pipelines. Also provide a discussion on the effects of <br /> buoyancy, as appropriate. <br /> e. General earthwork recommendations, including site preparation, structural fill <br /> recommendations and compaction requirements, suitability of on-site soils for reuse in <br /> trench backfill, mitigation of unsuitable soil conditions, impacts of weather and <br /> construction activities on site soils, and temporary and permanent cut slope requirements. <br /> f. Drainage and erosion considerations, including construction dewatering considerations <br /> andestimated permeability coefficients based on laboratory sieve analyses. <br /> g. Provide a summary of subsurface conditions encountered as information becomes <br /> available, and attend three design team meetings, as requested. Prepare a written report <br /> presenting our conclusions and recommendations along with supporting boring logs, <br /> laboratory data, and other appropriate figures. <br /> h. Review preliminary plans and specifications and provide comments and additions with <br /> respect to geotechnical considerations. <br /> City Responsibility: <br /> 1. Secure right-of-entry from private property owners, as needed. Review proposed boring <br /> locations. <br /> 2. Provide field locate marks for buried utility lines on the lift station site. <br /> Deliverables: <br /> 1. Eight(8)bound copies and one(1)loose copy of the Draft and Final Geotechnical Reports. <br /> Assumptions: <br /> 1. The anticipated subsurface conditions and the associated risks are generally known for this area. <br /> However, if the subsurface exploration program reveals unusual subsurface conditions, which <br /> may increase the risk of construction, the expansion of the exploration program will be <br /> considered. <br /> PROPOSED BUDGET <br /> Our services will be performed and billed based on actual hours worked multiplied by hourly rates for a <br /> total amount not to exceed $16,500. We will not exceed this estimate without a change to the scope of <br /> services. We will not proceed with a revised scope without your prior authorization. <br /> t'�G <br /> File No.0661-068-00 GEOENGINEERS <br />
