Exhibit A-1 <br /> KRAZAN&ASSOCIATES, INC. UP3730 <br /> Proposal No.G20165WAL <br /> Everett Water Main Replacement"V" <br /> Everett,WA <br /> March 13,2020 <br /> Page 3 <br /> cleared, Krazan would be available to coordinate with the City's Survey Consultant <br /> to allow boring completion prior to the completion of the surveyor's field work. <br /> B. Field Exploration: We plan to conduct 13 soil borings at the Water Main <br /> Replacement "V" project locations using a subcontracted drill rig to investigate the <br /> subsurface soil and groundwater conditions. An experienced geotechnical engineer <br /> or geologist will visually classify soil samples obtained in the field and maintain logs <br /> of the soil borings. Representative samples of the subsurface soils encountered in the <br /> geotechnical explorations will be collected and sealed in plastic bags. <br /> C. Laboratory Testing: Samples of the materials encountered in the soil borings would <br /> be collected for appropriate laboratory testing to determine the engineering <br /> characteristics of the on-site soils. These samples will be transported to our <br /> laboratory for further examination and testing, and to determine the physical and <br /> engineering properties of the on-site soils. It is important to note that the actual <br /> testing schedule would be dependent on the type of soils encountered within the soil <br /> borings. As engineering analyses and laboratory testing proceeds, we may identify <br /> additional tests that may be appropriate for the project. <br /> D. The data from the soil borings and laboratory testing, along with our experience with <br /> similar projects, will allow us to evaluate the geotechnical engineering properties of <br /> the subsurface soils and provide design and construction recommendations for the <br /> project. <br /> 4. Provide Geotechnical Design Recommendations <br /> We will conduct the necessary engineering analyses utilizing the data acquired from the <br /> geotechnical explorations and subsequent laboratory testing to characterize the site soils, <br /> determine the presence and depth of groundwater and its potential impact on the <br /> proposed construction and prepare earthwork recommendations. <br /> In addition to the geotechnical engineering analyses, our report will include a section <br /> addressing the geologic setting of the site and associated geologic hazards. The report <br /> will include the results of our field exploration and laboratory tests, and geotechnical <br /> conclusions and recommendations for the design and construction of the project. At a <br /> minimum,our report will provide the following information: <br /> • Geotechnical parameters for trench shoring design including lateral <br /> pressures,and partial shoring considerations; <br /> • Excavation and temporary slope considerations; <br /> • Pipe support including bedding and backfilling,and discussion regarding any <br /> areas of inadequate pipe foundation conditions encountered in the <br /> explorations; <br /> • Construction dewatering considerations including depth to groundwater <br /> observed during drilling and estimated permeability coefficients based on <br /> laboratory sieve analyses; <br /> • Soil corrosiveness <br /> Krazan&Associates,Inc. <br /> Offices Serving The Western United States <br />
