The geotechnical investigation, evaluations, and recommendations for the Port of Seattle Terminal 18/20 Improvement Project are described and compared with observed performance during construction. Topics covered include tensile failure of precast prestressed concrete piles, slope deformations resulting from dredging and pile driving, and seismic response evaluations. The volume change characteristics during shear of the mostly cohesionless alluvial soils are considered to be of critical importance in evaluating behavior. Based on the Terminal 18/20 project and experience from other port developments in the Puget Sound region, conclusions are drawn regarding geotechnical engineering for future port facilities in similar alluvial soils.
