KRAZAN&ASSOCIATES,INC. Proposal No. G21870WAL Everett Water Main Replacement"W" Everett, WA October 5,2021 Page 2 SCOPE OF SERVICES Our geotechnical services will be performed in general accordance with the scope of services as presented in Exhibit A-1. Below is a summary of the services to be provided: 1. Review Previous Geologic and Subsurface Information A. Review available subsurface information, existing construction data and other available geotechnical reports for the site vicinity. 2. Plan the Exploration Program and Obtain Permits A. Exploration Program: i. The water main alignments are in areas mapped as glacially compacted soils. We plan to explore the site with approximately nine(9)geotechnical borings: • Five (5) borings are planned in Wilmington Avenue with spacing of 300 to 400 feet along the proposed alignment; • Four(4)borings are planned in Hoyt Avenue with spacing of 300 to 400 feet along the proposed alignment; ii. The borings will primarily be located within the paved surface to allow measurement and documentation of the pavement type and thickness. The boring locations have been chosen to minimize interference with traffic flow at the intersections and to provide representative samples of the subsurface conditions. The borings will likely extend to depths of approximately 9.0 feet below the pavement surface depending on soil conditions. B. Submittals: We understand that the City Traffic Engineering Group will provide standard traffic control plans,which will be submitted along with the boring locations to the City of Everett for review for right-of-way permit applications. We plan to notify the public to avoid parking in the planned exploration areas by posting no parking signage with a minimum lead time of 48 hours prior to the start of drilling. We will remove the no parking signage after the work is completed. 3. Field Exploration and Laboratory Testing A. Site Visit to Clear Boring Locations:We will plan a visit to the project site prior to the explorations to mark the proposed soil boring locations for the underground utility locates. The public utility locate service will then be notified of our planned explorations. We also plan to subcontract a private utility locate company to evaluate whether there are subsurface utilities near the soil boring locations. After the boring locations are cleared,Krazan would be available to coordinate with the City's Survey Consultant to allow the boring locations to be surveyed prior to the completion of the surveyor's field work.
