Our Approach

Callahan is committed to building strong, long-lasting client relationships, and to consistently delivering solutions that exceed expectations. It’s why we are a leader in construction management, and why on average, 85 percent of our work comes from repeat clients.

Here are just a few of the solutions
we've created for our clients

We are a full-service firm, and offer a unique range of enhanced preconstruction services that allow us to deliver even better value to our clients. Our architectural, civil engineering and M/E/P/S peer review teams work in consultation with owners and designers to develop a precise set of plans, and coordinate everything from cost analysis and site selection, to the feasibility studies required for financing and permitting.

These preconstruction services bring us new ways to increase efficiency, provide value engineering, and address possible challenges related to project cost or schedule in the field. Combine this with our experienced, relationship-focused team, and it’s no wonder clients depend on us to complete projects with even the most complex constructability, budget, and schedule challenges.
