<br /> City of Everett Exhibit A— Scope of Work
<br /> Water Main Replacement K October 5, 2010
<br /> UP No. 3443 Page 3 of 9
<br /> walks and trails, utility poles, street lights, guy wires, buried utility vaults,
<br /> telephone pads, electric transformer boxes,junction boxes, valve boxes,
<br /> hydrants, water services, blow-offs, PRV vaults, meter boxes, water shut-offs,
<br /> individual service lines, power poles, overhead and buried
<br /> power/telephone/cable/fiber optics, traffic signals, loop detectors in pavement,
<br /> traffic control boxes, lane markings, crosswalk markings, guard rails, Jersey curb,
<br /> traffic signs, surface markings from utility locates, mailboxes, fences, landscaping
<br /> items, top and bottom of rockeries/retaining walls, brick pavers, driveway edges,
<br /> trees, shrubbery, PC and PT of street, sidewalk and trail centerline, curb radii,
<br /> and 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 10 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. Prepare environmental assessment; including researching known contaminated
<br /> soils sites within the project vicinity and monitoring for contaminated soils during
<br /> the borings.
<br /> 3. 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.
