Established in 1978, Colantonio is a $75 million firm offering preconstruction, general contracting and construction management services.  We specialize in the academic, affordable housing, municipal and historical restoration markets, with a focus on complex renovations.

In these competitive times, we offer our clients the benefits of experience, self performance and low personnel turnover.



Our Project Managers average 24 years of construction experience; our Project Superintendents average 32 years.   Every one of our projects gets an "A" team.   We keep PMs and Supers together as a team whenever possible, providing a smooth and efficient process for our clients.


Self Performance

We self perform in many trades, including carpentry and site work.  First-hand knowledge allows us to develop more accurate cost estimates, reduce exposure to schedule delays and ensure the highest quality of work. 


Low Personnel Turnover

One way that Colantonio retains its talented staff is by assigning manageable workloads (for example, only 1 or 2 projects are assigned to each Project Manager).  Preconstruction and project management personnel focus more of their time on each project, discussing issues face-to-face on a daily basis.  A team that works well together fosters collaboration among all project stakeholders and results in high productivity.
