September 5, 2024 BCE a Gannett Fleming TranSystems Company 6021 12th St E, #200 Fife, WA 98424 (253) 922-0446 Attn: Mr. Ben Hedin, PE Proposal for Geotechnical Services City of Everett Transit 33rd Street & Cedar Street Everett, Washington Doc ID: BCE.COET.P.doc INTRODUCTION We are pleased to submit this proposal for geotechnical engineering services for the proposed charging station Infrastructure Project to be constructed at the above site address. Our understanding of this project is based on our conversations with you, our review of the Site Plan prepared by the City of Everett, our September 4, 2024 pre-proposal site reconnaissance, and our experience in the general area. SCOPE OF SERVICES The purpose of our scope will be to evaluate the surface and subsurface conditions across the site as a basis for developing geotechnical conclusions and recommendations. Specifically, we recommend the following scope of services: 1. Field Preparation – We will prepare a Proposed Exploration Plan for approval by the project team. Once approved, w e will contact the local utility locating service and attend requisite training necessary to work on site, as required. 2. Site Reconnaissance – We will walk the site to observe the current conditions and mark all exploration locations. 3. Subsurface Exploration – Our subsurface exploration program will include multiple elements developed to generate the data necessary for the geotechnical analyses required for the project. Specifically, our subsurface exploration program will include the following. • Up to three Dynamic cone penetrometer (DCP) tests will be performed within the proposed pavement areas to depths of 3 feet below existing grade or refusal, whichever comes first. • Up to three test pit explorations to depths of approximately 7 to 10 feet below the existing ground surface. A small scale Pilot Infiltration Test (PIT) will be completed within one of the test pits
