EXHIBIT A-1 <br /> Aspect <br /> CONSULTING <br /> June 30, 2020 <br /> Arnie Roshak, P.E.,Associate Engineer <br /> City of Everett,Public Works—Utilities Engineering <br /> 3200 Cedar Street <br /> Everett,Washington 98201 <br /> Re: Proposal for Geotechnical Engineering Services <br /> Grand Avenue Utilities Replacement, UP No. 3711 <br /> Grand Avenue between 19th Street and Hewett Avenue <br /> City of Everett, Washington <br /> Project No. 170095-02 <br /> Dear Ms. Roshak: <br /> As requested, Aspect Consulting,LLC (Aspect)has prepared this proposal for the City of Everett's <br /> (City) Grand Avenue Utilities Replacement, UP No. 3711 (Project). The following proposal <br /> includes our project understanding, scope of work,cost estimate,and schedule for completing the <br /> tasks and services. <br /> Project Understanding <br /> We understand the City plans to install new water, sanitary sewer, and storm pipe on Grand Avenue <br /> from 19th Street to Hewitt Avenue. The Project will replace aging cast iron water mains, and <br /> address condition and capacity issues in the combined sewer system. The project will include <br /> stormwater separation,with installation of a new storm main. The new combined sewer main will <br /> replace the aging dual sewer mains along Grand Avenue. In the future,the storm and sewer pipes <br /> will convey flow to the proposed Port Gardner Storage facility. Aspect previously completed a <br /> geotechnical evaluation 1 for the water main replacement, previously referred to as Water Main S <br /> Replacement. <br /> Based on the plans and profiles provided by the City,the additional storm and sanitary sewer <br /> utilities will extend as deep as 20 feet below existing ground surface(bgs), significantly deeper than <br /> our previous explorations. Therefore,the City would like additional explorations to evaluate <br /> subsurface soil and groundwater conditions as a basis for geotechnical engineering <br /> recommendations in the design and construction of the storm and sanitary sewer main replacement. <br /> Proposed Scope of Work <br /> The purpose of our geotechnical services is to evaluate subsurface soil and groundwater conditions <br /> as a basis for providing geotechnical engineering recommendations. Our work is broken into the <br /> tasks outlined below. <br /> 'Aspect Consulting,LLC,2017,Geotechnical Letter Report—Draft,Water Main Replacement"S",Grand Avenue between 19th Street and <br /> Hewitt Avenue,Everett,Washington,Aspect Project No. 170095,dated May 11,2017 <br /> —�— Aspect Consulting,LLC 710 2nd Avenue Suite 550 Seattle,WA 98104 206.328 7443 wvvw.aspectconsulting.com <br />
