Cumberland-based Sevee & Maher Engineers Inc. has added 16 employees through two acquisitions — one in Maine and one out of state — with further expansion on the radar.
The company, whose work spans projects from solar installations to an award-winning commercial greenhouse for Estabrook’s in Pownal, announced both deals Monday.
In Maine, Sevee & Maher acquired the civil and traffic engineering and survey practices of James W. Sewall Infrastructure in Bangor, expanding its civil engineering operations while adding traffic engineering and surveying capabilities.
Sevee & Maher also acquired Uhl & Associates, a water resources company based in Lambertville, N.J.
Terms of the deals were not disclosed, but a spokesperson said all five employees of the New Jersey firm and 11 employees from Sewall Engineering’s civil, traffic/transportation engineering and survey teams will remain under the new ownership. That brings Sevee & Maher’s workforce total to 131 employees, including a recent hire.
Sevee & Maher, ranked No. 11 among Maine’s largest engineering firms in the 2026 Mainebiz Book of Lists, provides civil engineering, site investigation and remediation, environmental regulatory compliance, water resource development, industrial hygiene, power engineering and other services to commercial, industrial, governmental and residential clients nationwide.
The firm acquired Chicago-based Bono Consulting Civil Engineers in 2022, and Environmental Safety & Hygiene Associates, formerly based in Westbrook, in 2018.
Expansion strategy
Asked about further expansion, Sevee & Maher President Erik Clapp said the company will continue to evaluate potential acquisitions.
The firm “is always looking to better serve our clients and for opportunities for our employees to advance their careers,” he said in a statement emailed to Mainebiz. “These opportunities often come through acquisitions.”
As a general rule, Clapp said the strategy is to evaluate opportunities based on geographic and service-area priorities, with an emphasis on “client-focused service and employee culture.”
