Who We Are

We haven’t met a challenge yet that we didn’t like.

Our Professional Engineers are registered in 35 states, five Canadian Provinces and they have local and international experience solving engineering challenges. Colby Co. also offers Architecture with registrations in the New England states, including Maine-licensed Architects. Our experience has been that there is always more than one way to solve a problem. Finding creative and appropriate solutions is what motivates us.

*We have licenses in the states and territories marked with orange.

Colby Co. streamlines the design process by offering the major building engineering and architecture disciplines with an in-house staff. There are few substitutes for having the electrical, mechanical, fire protection, structural and civil engineering and architecture disciplines under one roof. Working in close proximity encourages constant communication between the engineering and construction services disciplines.


From boiler design to building renovations, energy audits to arc flash analysis, chiller system design to construction administration, one of our strengths is the diversity of project experience on which we can draw.
