3 <br /> City of Everett Exhibit A—Scope of Work <br /> Water Main Replacement K November 12, 2010 <br /> UP No. 3443 Page 3 of 9 <br /> bottom of rockeries/retaining walls, brick pavers, driveway edges, trees, <br /> shrubbery, PC and PT of street, sidewalk and trail centerline, curb radii, and <br /> existing survey monuments inside and within 100 feet of the proposed <br /> construction area. <br /> 4. Provide survey mapping at 1" = 20' scale for ANSI D, 22" x 34" size drawings. <br /> Show all topographic data that was collected: right-of-way, centerline, property <br /> boundaries, easements, and City-provided GIS data, 2-foot contour intervals <br /> (with major contour lines at 10-foot intervals). Field verify street addresses. <br /> Coordinate with City of Everett CAD manager for drawing templates and drawing <br /> setup. Submit the first survey base map version electronically for City review to <br /> determine design conformance with City Standards (sheet size, layout, layer <br /> conventions, line types, etc.). Consolidate survey and mapping information in the <br /> Survey Binder as outlined in the City CAD and Survey Standards. <br /> 5. Create City of Everett Prototype Standards for project use. <br /> D. Geotechnical Engineering Services <br /> 1. Work with subconsultant, GeoEngineers, to obtain soil and groundwater data by <br /> auger borings (maximum depth of 10 feet assumed, up to 6 borings). Provide <br /> two additional borings near potential jacking pit locations along 3rd Avenue SE, <br /> south of 41st Street; these borings are planned to be 25 feet deep to provide <br /> adequate information for shoring design. This subtask will include researching <br /> local soils data, obtaining permits for drilling, procuring the services of a drilling <br /> company, traffic control, installing a piezometer in one of the deeper borings for <br /> subsequent groundwater monitoring, and up to four site visits to perform <br /> groundwater level monitoring. <br /> 2. Contract with GeoEngineers to provide soils report including boring logs, <br /> laboratory test results (moisture content, maximum density, particle size <br /> distribution, corrosion potential), and recommendations (backfill, mitigation of <br /> unsuitable soils, excavation and temporary slopes, erosion control, and <br /> dewatering as needed). The report will also contain recommendations relating to <br /> the boring/jacking operation. <br /> Deliverables: <br /> • Two hard copies of draft soils report for review by City <br /> • Two hard copies and one electronic copy of final soils report <br /> E. Preliminary Design <br /> 1. Collect and review data provided by the City, including GIS and mapping data, <br /> record plans, and electronic templates. <br /> 2. Check for potential utility conflicts based on utility field locates, utility as-built <br /> drawings, and survey information. <br /> 30 <br />
