Our Story

AHBL was founded in 1969 to bring a collaborative approach to the development of built environments. Our staff of 140 works together on projects of local and regional significance, serving both public and private clients from offices in Tacoma, Seattle, Tri-Cities and Spokane. AHBL is committed to creative design, cost effective solutions, capturing, and maintaining the sense of community, and integrating our area’s natural and cultural heritage into our ever-changing urban landscape. Our relationship-based practice is grounded upon the values of honesty, integrity, and making our clients’ needs our number one priority.

Our firm embraces a responsibility to contribute to our region and enhance the lives of community members that live, work, and play in or communities. As experts in civil and structural engineering, we are often called in to provide assessments of buildings or capital facility assets to determine overall condition and lifespan of buildings or exterior assets including site paving, storm ponds and other site features.  Our teams help identify visible and discernable components and elements requiring maintenance, repair, replacement, upgrades, or other planned action. We have contributed to facility condition assessments for transit agencies, cities, and school districts throughout Washington state.
