Haley & Aldrich, based in Burlington, Mass., has acquired Seattle-based Hart Crowser to offer environmental and geotechnical engineering consulting and construction services to clients in all major U.S. markets. Hart Crowser will operate as a division of Haley & Aldrich through the end of 2021 and will then be known as Haley & Aldrich. Terms were not disclosed.
Clients and the staff of both companies will have full access to the firms’ expanded geography and technical expertise. Together, Haley & Aldrich and Hart Crowser have more than 800 staff and 37 office locations. Their practitioners live and work in every U.S. state and perform work internationally.
“Adding Hart Crowser’s high-end geotechnical capabilities — in particular in seismic design — and deep knowledge and experience in the Northwest and Pacific will delight Haley & Aldrich clients,” said Larry Smith, chief executive officer of Haley & Aldrich. “This merger will allow both companies to offer our clients throughout the U.S. an even greater depth of technical expertise across a broad range of environmental and geotechnical engineering services.”
Among the firms’ achievements, Haley & Aldrich developed the first regenerable resin technology application for 1,4-dioxane and per- and polyfluoroalkyl (PFAS) remediation, now a widely adopted approach. The company later formed ECT2, a wholly owned subsidiary, to develop and market the technology, and sold ECT2 in 2019.
Hart Crowser engineers work with governments and communities around the world after major earthquakes and tsunamis to guide them in establishing innovative and standard practices to protect their people, buildings, and infrastructure from future natural disasters.
“During our work together on past projects, we discovered incredible similarities between our two companies in culture, core values, and practice,” said David Winter, Hart Crowser president and CEO. “The merger is simply a great fit, and the Hart Crowser team looks forward to a future of growth together.”
