Haley & Aldrich Inc. is committed to delivering the value our clients need from their capital, operations, and environmental projects. Our one-team approach allows us to draw from our 800 engineers, scientists, and constructors in 33 offices for creative collaboration and expert perspectives. Since our founding in 1957, we have one goal in all we do: deliver long-term value efficiently, no matter how straightforward or complex the challenge. In 2020, Haley & Aldrich acquired Hart Crowser, an engineering and environmental consultancy with extensive expertise in the Pacific Northwest and recognized for its cutting-edge performance-based seismic design methods.
