KRAZAN & ASSOCIATES, INC.Proposal No. G24295WAL Everett Watermain Replacement “X” Everett, WA March 22, 2024 Revised April 2, 2024 Page 4 Krazan & Associates, Inc. Offices Serving the Western United States will include the results of our field exploration and laboratory tests, and geotechnical conclusions and recommendations for the design and construction of the project. At a minimum, our report will provide the following information: Geotechnical parameters for trench shoring design including lateral pressures, and partial shoring considerations; Excavation and temporary slope considerations; Pipe support including bedding and backfilling, and discussion regarding any areas of inadequate pipe foundation conditions encountered in the explorations; Construction dewatering considerations including depth to groundwater observed during drilling and estimated permeability coefficients based on laboratory sieve analyses; The evaluation of soil corrosiveness will include laboratory testing for soil pH, chloride and sulfate content. Soil resistivity testing is not planned as part of this scope, but can be performed if needed, under a separate contract. The glacial soils anticipated in these project areas typically have a low potential for corrosion; Recommendations for seismic design considerations based on the 2021 IBC, including site coefficient and ground acceleration; Recommendations for erosion control during construction. We plan to submit the geotechnical engineering report via email as a pdf file. Hard copies of the geotechnical report can be provided on request. The services will be performed in accordance with generally accepted standards of the geotechnical engineering profession. All reports will be signed and stamped by a State of Washington registered professional engineer. 5.Geotechnical Communications, Design Report and Meetings A Statement of Qualifications and the resumes of key personnel are attached to this proposal. Our geotechnical engineer and geologist will be available to provide a summary of the subsurface conditions encountered in the explorations and answer questions after the field work is completed. During the construction phase of the project, our representative will be available, under a separate contract, to travel to the site on an as- needed basis to observe the soil conditions to confirm that they are consistent with the findings of our geotechnical evaluation. A separate cost estimate for construction monitoring can be given at a later date, at your request. Krazan would be available to coordinate with the City’s survey consultant to allow time to locate the borings and establish ground elevations. 6.Project Milestones The project schedule in Exhibits A-1 indicates the Notice to Proceed (NTP) will be available by April 15, 2024.
