Haley & Aldrich and Hart Crowser Join Forces to Offer Their Renowned Environmental and Engineering Consulting Services Nationwide

Haley & Aldrich, headquartered in Burlington, Mass., has acquired Hart Crowser, headquartered in Seattle, for undisclosed terms. Hart Crowser will operate as a division of Haley & Aldrich through the end of 2021 and will then be known as Haley & Aldrich. The two firms have complementary services covering the environmental and geotechnical engineering consulting and construction spectrum. Their mutual commitment to client satisfaction and solving complex issues will now benefit a wider range of U.S. clients in all major markets.

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.

Each firm has earned a reputation for excellence and has advanced the environmental and engineering practices over the decades through their innovative approaches to solving their clients’ toughest challenges. For example:

  • 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.
  • Through Haley & Aldrich’s Lean Journey Pathway applied training program, Lean practitioners train Haley & Aldrich staff at all levels to incorporate Lean principles into their daily work, resulting in greater respect for people, reduced waste, and higher quality and value.
  • Hart Crowser has the most experience in cutting-edge performance-based seismic design methods for high-rise buildings in the U.S. and was the first in the Northwest to use the conditional mean spectrum analysis method.

“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. 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,” said Larry Smith, Chief Executive Officer of Haley & Aldrich.

David Winter, Hart Crowser’s President and Chief Executive Officer, said, “During our work together on past projects, we discovered incredible similarities between our two companies in culture, core values, and practice. The merger is simply a great fit, and the Hart Crowser team looks forward to a future of growth together.”
