November 7, 2024 <br />HWA Project No. 2024-P272-21 <br />Scope of Work 2 HWA GeoSciences Inc. <br />FIELD EXPLORATIONS: <br />• Collect and Review Available Geotechnical Data: HWA will review readily available <br />geotechnical information along the project corridor. This review will include online <br />geotechnical databases, geologic maps, and HWA library. <br />• Perform Geotechnical Site Reconnaissance and Mark Utility Locates: HWA will <br />conduct a geotechnical site reconnaissance of the project area. This reconnaissance will <br />be used to identify geotechnical challenges and to assist in planning the geotechnical <br />exploration program. While on site, HWA will mark the proposed exploration locations <br />and arrange for utility locates using the Utility Notification Center. HWA assumes <br />load/unload and travel to site requires 1 hours in each direction. <br />• Plan Geotechnical Field Exploration Program: HWA will plan and coordinate the <br />geotechnical exploration program for the project. The exploration program will consist <br />of pushing two cone penetrometer tests (CPT), one at each outfall location, advanced to a <br />depth of 100 to 125 feet below ground surface to provide data for design of the proposed <br />improvements. The planning efforts include coordination with subcontractor and the City <br />of Everett. <br />• Generate Exploration Work Plan Memorandum: HWA will prepare a Geotechnical <br />Work Plan Memoranda, which will include a project specific Health and Safety Plan, for <br />the proposed field work. The work plan will be submitted to the design team and <br />appropriate jurisdictions for review and approval. The work plan will detail the type, <br />location, and extent of proposed field explorations along with logistics necessary to <br />perform the work. HWA assumes traffic control measures will not be needed for <br />conducting the exploration work. The work plans will also be used for utility locating <br />clearances and for permitting that may be necessary to access the exploration locations. <br />We assume the required permits will be provided at no cost to HWA. <br />• Conduct Geotechnical Explorations: HWA will conduct 1 day of CPT testing <br />consisting of a total of 2 CPT explorations, one at each outfall location, to assess the <br />subsurface soil and groundwater conditions. The proposed CPT tests will be advanced to <br />a depth of 100-125 feet or the practice refusal of the equipment whichever is shallower. <br />All CPT tests will be conducted within the Right-of-Way of the City of Everett or on <br />private properties within the proposed project area, in coordination with the City. The <br />City will provide all necessary permits for the exploration work, including street-use <br />permits, right-of-way permits, right-of-entry permits, and temporary construction <br />easements (if required), at no cost to HWA. <br />HWA assumes conducting the proposed CPT tests will take 1 mobilization and 1 working <br />day to complete and the work will NOT require traffic control flaggers.
