Salas O’Brien’s sixth merger in 2022 creates a team of over 1,650 across North America

Maine-based Allied Engineering has joined the company. This expands Salas O’Brien’s presence in New England and creates a combined firm of more than 55 offices with over 1,650 team members and 370 registered professionals.

The Allied team’s capabilities and portfolio complement Salas O’Brien’s existing mechanical, electrical, plumbing, and structural engineering work across North America. The merger increases our combined team’s ability to provide comprehensive, integrated, multi-disciplinary engineering services.

As the next step in Salas O’Brien’s strategy to be local everywhere, with international resources, the Allied team will continue to be managed by its current leaders and will adopt the Salas O’Brien name after a transition period.

This merger marks the sixth company to join Salas O’Brien this year.

“Allied Engineering has built an impressive reputation as the go-to firm for building engineering design solutions across New England,” said Darin Anderson, Salas O’Brien chairman and CEO. “Their team of experts takes a lot of pride in their work, and we are excited to join with them and continue their tradition of engineering excellence.”

Salas O’Brien continues to grow as part of an ambitious plan to create the most respected engineering firm in the world, as measured by clients and team members.

“Salas O’Brien’s broader spectrum of in-house services will benefit the clients and communities we serve,” said Catherine Faucher, president of Allied Engineering. “Our entire leadership team looks forward to building upon the strong legacy of service Allied Engineering has established over the past six decades.”

For decades, the Massachusetts College of Art and Design showcased contemporary art exhibitions, but the lack of air conditioning, restrooms, and elevators prevented guests from having an optimal experience. These issues spurred the college’s largest private fundraising campaign yet, engaging 424 donors to renovate the 110-year-old space.
