April 12, 2016 HWA Project No. 2016-P044-21 testing of potentially contaminated soils will be completed under a management reserve budget and not the primary approved budget. • Groundwater monitoring: Upon completion of each of the groundwater monitoring wells, HWA will install groundwater monitoring transducers to collect groundwater data for a period of at least 8 weeks. HWA assumes two site visits to download and collect the transducer data throughout the project. • Generate Boring Logs and Assign Laboratory Testing: HWA shall prepare summary boring logs and perform laboratory testing to evaluate relevant physical properties of the site soils. Laboratory testing will include moisture contents, grain-size distribution, and Atterberg Limits. All laboratory testing will be performed in general accordance with the corresponding ASTM procedures. • Develop Geologic Cross-Section: From the results of our slope reconnaissance and existing subsurface data, HWA will develop geologic profiles where appropriate. These preliminary profiles will show near surface soil conditions and will be provided in the preliminary geotechnical report. • Complete Preliminary Geotechnical Engineering Assessment: HWA will complete preliminary geotechnical analysis to asses the geotechnical conditions of the site and identify any geotechnical issues that will need to be addressed during design. This assessment will be conceptual in nature and will exclude any and all soil structure interaction analysis. • Preliminary Geotechnical Engineering Report: HWA will generate a preliminary geotechnical engineering report that will contain the results of the geotechnical engineering investigation, including description of surface and subsurface conditions; a site plan showing exploration locations and other pertinent features; summary boring logs; and laboratory test results. The report will provide a narrative and geotechnical recommendations for each of the above described geotechnical aspects of the project. • Project Coordination Meetings: HWA will attend up to one project coordination meeting at the City of Everett offices. This meeting will be meant to convey the geotechnical considerations of the site to the City and possible design team. • Final Design Geotechnical Engineering: HWA will complete geotechnical engineering analysis required to provide design recommendations for the project. These analysis will include slope stability analysis, settlement analysis, lateral earth pressure analysis, bearing capacity analysis,temporary shoring analysis and dewatering recommendations.
