Hart Crowser

What Hart Crowser does

Hart Crowser is a U.S. environmental and geotechnical engineering consultancy founded in 1974, now operating as a division of Haley & Aldrich following an integration that combined Hart Crowser's Pacific Northwest and Pacific Islands expertise with Haley & Aldrich's national platform. The firm provides project-based professional consulting across geotechnical engineering (foundation design, earthquake engineering, ground improvement, rock engineering, geotechnical instrumentation, support of excavation), contaminated site management (site characterization, remediation, PFAS, emerging contaminants, vapor intrusion, sediments, environmental due diligence), brownfields redevelopment, construction-phase services, EHS compliance, water resources, sustainability, disaster and climate resilience, and lean process consulting. Hart Crowser is specifically recognized for its performance-based seismic design methods applied to U.S. high-rise buildings, a technically demanding niche within structural and geotechnical engineering.

The business operates on a professional services revenue model, delivering engagements through direct client relationships rather than productized offerings, with services quoted per project based on scope and complexity. The combined Haley & Aldrich / Hart Crowser entity employs approximately 800 staff across 33 U.S. office locations, with Hart Crowser's distinct headcount in the 101–250 range per firmographic data. GTM is enterprise field sales targeting government infrastructure, real estate developers, industrial/manufacturing, energy, mining, data centers, aerospace, and education/healthcare/cultural institutions. No productized software, API, or AI platform is offered — delivery is labor-based consulting.

Post-merger, Hart Crowser clients gain access to the full national cadre of environmental and geotechnical staff across nine markets, while Haley & Aldrich gains deeper Pacific Northwest and Pacific Islands domain coverage. Marketing is conducted through a corporate website, LinkedIn/Twitter/Facebook presence, publications, and industry engagement, with leads captured via a service-area/segment-qualified contact form.
