Seattle
Haley & Aldrich’s hub for Pacific Northwest clients.
Clients rely on our Seattle geotechnical engineers and environmental consultants.
Overlooking the Puget Sound, Haley & Aldrich’s Seattle office provides a base for Haley & Aldrich consultants to partner with clients in the Pacific Northwest region. Among other services, our local professionals focus on:
- Geotechnical engineering
- Climate change and seismic resilience consulting
- Environmental, health, and safety consulting
- Contaminated site management
- Water resources consulting
In addition to many other projects in Seattle, we managed foundation design and monitoring for the city’s Climate Pledge Arena, an award-winning project that built an enduring city landmark. The arena is only blocks from the office, as are many other businesses, restaurants, and local landmarks.
