EXHIBIT A-1 KRAZAN&ASSOCIATES, INC. Proposal No. G18689WAL Everett Water Main Replacement"U" Everett,WA August 16,2018 Page 3 C. Laboratory Testing: Samples of the materials encountered in the soil borings would be collected for appropriate laboratory testing to determine the engineering characteristics of the on-site soils. These samples will be transported to our laboratory for further examination and testing, and to determine the physical and engineering properties of the on-site soils. It is important to note that the actual testing schedule would be dependent on the type of soils encountered within the soil borings. As engineering analyses and laboratory testing proceeds, we may identify additional tests that may be appropriate for the project. D. The soil boring and laboratory data and our experience with similar projects will allow us to evaluate the geotechnical engineering properties of the subsurface soils and provide design and construction recommendations for the project. 4. Provide Geotechnical Design Recommendations We will conduct the necessary engineering analyses utilizing the data acquired from the geotechnical explorations and subsequent laboratory testing to characterize the site soils, determine the presence and depth of groundwater and its potential impact on the proposed construction and prepare earthwork recommendations. In addition to the geotechnical engineering analyses, our report will include a section addressing the geologic setting of the site and associated geologic hazards. The report 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; • Construction dewatering considerations including depth to groundwater observed during drilling and estimated permeability coefficients based on laboratory sieve analyses; • Recommendations for seismic design considerations including site coefficient and ground acceleration; • Recommendations for erosion control during construction. We plan to submit the 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. Krazan&Associates,Inc. Offices Serving The Western United States
