KRAZAN&ASSOCIATES,INC. Proposal No. G21870WAL Everett Water Main Replacement"W' Everett,WA October 5,2021 Page 4 • 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 2018 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 Exhibit A-1 indicates the Notice to Proceed (NTP) will be available by November 1,202I. The fieldwork would commence as soon as possible upon receiving your authorization to proceed, upon obtaining utility clearances, and based on the availability of the subcontracted flaggers and drill rig. We will begin laboratory testing immediately upon completing the field exploration. We intend to submit a Draft Report on or before December 7, 2021. We anticipate submitting our Final Geotechnical Engineering Report by December 21,2021. Krazan&Associates,Inc. Offices Serving The Western United States
