Reviewing available published geologic data for the project vicinity and the design drawings of the existing bridge. Preparing a Health and Safety Plan prior to conducting field activities. Preparing a Traffic Control Plan in accordance with Work Zone Traffic Control Guidebook, MaineDOT, March 2015, and the MUTCD (FHWA). Engaging a drilling subcontractor to complete preliminary (Phase 1) and final design (Phase 2) subsurface exploration programs. Providing full-time observation during the subsurface exploration programs and classification of the soil samples in general accordance with Maine Department of Transportation (MaineDOT) guidelines. Engaging third-party laboratories to perform Atterberg limits, grain size analyses, and water contents of representative soil samples, and elastic moduli of rock in uniaxial compression on representative rock samples. Reviewed the results of the subsurface explorations, prepared a subsurface profile, and developed soil properties for geotechnical analyses. Developed geotechnical recommendations for the design and construction of a new integral abutment bridge supported on rock socketed H-piles. Preparing this geotechnical design report presenting the results of the subsurface explorations and our geotechnical analyses and recommendations.
