Sellen Construction
Seattle, Washington
This project involves redevelopment of an early 1940s warehouse to provide up to 200,000 square feet of new office space for the US Army Corps of Engineers, as well as a childcare facility and cafeteria. Our work includes assessing an innovative closed loop geothermal system, and conducting infiltration tests to support the design of stormwater management facilities.
Bird Construction
Joint Base Lewis-McChord, Washington
Hart Crowser provided geotechnical design for this $28 million Unaccompanied Enlisted Personnel Housing project. This 65,000-square-foot barracks for 178 soldiers also included a dining facility to serve 456 soldiers.
Korte Company
Whidbey Island, Washington
Hart Crowser provided state-of-the-art seismic design engineering for a major aircraft facility upgrade. The work included geotechnical engineering services for a seismic upgrade and retrofit, including additional explorations to evaluate subsurface conditions and a detailed probabilistic seismic hazard assessment (PSHA). Hart Crowser also prepared a construction contingency plan, detailing procedures to be followed if suspected environmental contaminants were encountered during excavation and renovation.
Schreiber, Starling & Lane Architects PC
Seattle, Washington
Hart Crowser provided geotechnical design and construction support for three new buildings for this college campus expansion over a period of 5 years. The work inlcuded the Apprenticeship and Education Center (Building A, 21,000 square feet) and the Puget Sound Industrial Excellence Center (Building C-1, 8,000 square feet, and Building D-1, 18,000 square feet). The facility is on a site in the Duwamish Waterway basin that is known for seismic hazards such as soil liquefaction.
Seneca Real Estate Group, Inc
Seattle, Washington
Hart Crowser provided geotechnical engineering and seismic design services for the new Seattle Central Library project. The uniqueness of the architectural design challenged the geotechnical engineers, requiring that we think innovatively to maintain continuity with the envisioned architectural concepts. We also provided support to the owner during arbitration of a design-build shoring system.
Port of Seattle
Seattle-Tacoma International Airport, Washington
This complex project for the Port of Seattle included geotechnical design of a new baggage screening building at Gate C1, relocation of Alaska Airline facility in Concourse C, and a security scanning module access shaft in South Satellite Terminal. We successfully overcame difficult constraints such as an existing transit tunnel below the excavation, tight construction access, and the need to minimize impact to airport operation.
Ivary & Associates/City of Redmond
Redmond, Washington
Our geotechnical engineering recommendations supported two additions to this building.
Yost Grube Hall/Olympic College
Bremerton, Washington
Hart Crowser provided geotechnical engineering design and construction for the two-story Science and Technology building, the three-story Humanities building, and a bookstore addition on the Olympic College Campus. Rather than use deep pile foundations or require complete excavation of the overlying unsuitable material, Hart Crowser suggested the use of ground improvements so that a more conventional and less expensive foundation could be used for building support.
