KRAZAN&ASSOCIATES,INC. <br /> Proposal No. G21870WAL <br /> Everett Water Main Replacement"W" <br /> Everett,WA <br /> October 5,2021 <br /> Page 3 <br /> B. Field Exploration: We plan to conduct nine (9) soil borings at the Water Main <br /> Replacement"W" project locations using a subcontracted drill rig to investigate the <br /> subsurface soil and groundwater conditions. Soil samples will be obtained using the <br /> Standard Penetration Test (SPT) as described in ASTM Test Method D1586. An <br /> experienced geotechnical engineer or geologist will visually classify soil samples <br /> obtained in the field,maintain logs of the soil borings and locate the borings on a site <br /> plan relative to the existing site features. Representative samples of the subsurface <br /> soils encountered in the geotechnical explorations will be collected and sealed in <br /> plastic bags for transport to our office laboratory. <br /> Environmental services, such as chemical analysis of soil and groundwater for <br /> possible environmental contaminants, are not included in our scope of services for <br /> this project. Soil cuttings will be and managed in accordance with WA DOE <br /> requirements by our drilling subcontractor provided that they are not contaminated <br /> We will note the City Engineering Dept. immediately if indications of contamination <br /> are noted(e.g., odor or staining) in the soil cuttings. If necessary, a change order <br /> will be submitted or analytical testing and disposal <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 geotechnical engineering design and construction <br /> recommendations for the 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 /> Krazan&Associates,Inc. <br /> Offices Serving The Western United States <br />
