Geotechnical

Pier D, Nimitz Class Carrier Pier

PN&D/US Navy
Naval Station Kitsap, Bremerton, Washington

Hart Crowser was the geotechnical engineer for a new, 1,400-foot aircraft carrier pier. By designing and conducting a detailed test pile installation program, we greatly reduced the required depth of embedment for the high capacity piles. We also assessed the potential environmental effects of dredging and proposed sediment disposal alternatives.

Seattle Aquarium, Pier 59 Seismic Retrofit

Seattle Parks and Recreation
Seattle, Washington

Hart Crowser provided the geotechnical exploration and foundation design for the Seattle Aquarium building and aging pier structure for the Seattle Parks and Recreation Department. Project planning required consideration of construction constraints such as vibration and noise impact to the marine environment, aquarium operations, and limited access. The photo shows driving pipe piles to support the retrofitted pier.
