KRAZAN & ASSOCIATES, INC.Proposal No. G24295WAL <br />Everett Watermain Replacement “X” <br />Everett, WA <br />March 22, 2024 <br />Revised April 2, 2024 <br />Page 3 <br />Krazan & Associates, Inc. <br />Offices Serving the Western United States <br />B.Field Exploration: We plan to conduct twelve (12) soil borings at the Water Main <br />Replacement “X” 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 engineer or geologist will visually classify soil samples obtained in the <br />field, maintain logs of the soil borings and locate the borings on a site plan relative to <br />the existing site features. The boring logs will include pavement types and thickness. <br />Representative samples of the subsurface soils encountered in the geotechnical <br />explorations will be collected and sealed in plastic bags for transport to our office <br />laboratory. Soil cuttings will be collected and managed in accordance with WA DOE <br />requirements. <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 notify the City immediately if indications of contamination are noted — e.g., <br />odor or staining is noted in the soil cuttings. If necessary, a change order will be <br />submitted for analytical testing and disposal <br />C.Laboratory Testing:Samples of the materials encountered in the soil borings would <br />be collected and transported to our laboratory for appropriate laboratory testing to <br />determine the engineering characteristics of the on-site soils. The testing will include <br />moisture content, particle size distribution, and consistency of cohesive soils. It is <br />important to note that the actual testing schedule would be dependent on the type of <br />soils encountered within the soil borings. As engineering analyses and laboratory <br />testing proceeds, we may identify additional tests that may be appropriate for the <br />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 />a)We will provide a geologic description of the site vicinity based on published <br />information, and previous experience in the area. We will conduct the necessary <br />engineering analyses utilizing the data acquired from the geotechnical explorations <br />and subsequent laboratory testing to characterize the site soils, determine the <br />presence and depth of groundwater and its potential impact on the proposed <br />construction and prepare earthwork recommendations. <br />b)We will provide recommendations for earthwork and site preparation including <br />suitability of on-site soils for reuse in trench backfill, placement and compaction of <br />trench backfill, and mitigation of unsuitable soil conditions. An evaluation of the <br />effects of weather and/or construction equipment on site soils will be included. <br />c)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.
