4 <br /> EXHIBIT C <br /> GEOTECHNICAL ENGINEERING SCOPE OF WORK <br /> CITY OF EVERETT <br /> UP NO. 3575, WATER MAIN REPLACEMENT "0" <br /> Introduction and Background <br /> The City plans to install new ductile iron water pipe and abandon in-place existing cast iron pipe <br /> within the City limits in downtown Everett along the following route: <br /> • Rockefeller Avenue from Hewitt Avenue to Everett Avenue <br /> The new mains are expected to consist of approximately 900 lineal feet of 8-inch diameter ductile <br /> iron water main. The new alignment will be within right-of-way will have between 36 and 48-inch <br /> cover. Construction methods include standard trench excavation. <br /> Scope of Services <br /> The purpose of geotech services is to evaluate subsurface soil and groundwater conditions as a <br /> basis for providing geotechnical engineering recommendations for design and construction of the <br /> water main replacement. Geotech's proposed scope of services will include, but not be limited to, <br /> the following tasks: <br /> 1. Review Previous Geologic and Subsurface Information <br /> a. Review subsurface information, existing construction data, and other available <br /> geotechnical reports in the vicinity regarding subsurface soil and groundwater <br /> conditions. <br /> 2. Plan the Exploration Program and Obtain Permits <br /> a. Complete a site visit to locate the proposed borings, plan the traffic control <br /> operations, and develop right-of-way permit applications, as required. <br /> i. Provide recommendation to number and locations of borings. Include rationale <br /> in Geotech's choice in the number and locations of borings. <br /> ii. Locate all borings within paved surface so as to measure and record paved <br /> surface types and thickness. <br /> b. Submit permit applications, traffic control plans, and boring exploration plans to City <br /> of Everett for review. <br /> 3. Field Explorations and Laboratory Testing <br /> a. Complete a site visit to meet with utility representatives and clear boring locations. <br /> The City's Survey Consultant will hire a private utility locator to aid in clearing the <br /> borings due to the numerous utilities. Coordinate with City's Survey Consultant to <br /> allow boring completion prior to surveyor's field work completion so as to eliminate <br /> additional trip by surveyor. <br /> b. Explore subsurface soil and note groundwater conditions at the site by drilling up to 4 <br /> borings to depths of 10 feet. Complete field explorations under the direction of a <br /> geotechnical engineer or geologist. The explorations will be located in the field by <br /> measuring or pacing from existing site features such as driveways, structures and <br /> other site features shown on the drawings. Geotech representative will maintain a <br /> detailed log of each exploration and obtain samples of the various materials <br /> encountered. Record pavement depths and pavement types encountered. The <br /> samples will be returned to geotech's office for additional examination and analysis, <br /> 56 <br />
