About TN Cost Group

TN Cost Group was built by people with real construction experience.

With more than 20 years of combined experience, our managing partners bring a practical understanding of how projects are built — from the field to the office. Our careers started in the trades and grew into construction management and preconstruction, giving us a unique perspective on both the estimating process and the realities of execution.

We created TN Cost Group after seeing contractors face the same challenges repeatedly — more opportunities to pursue, but not always enough estimating and preconstruction capacity, missed bids, and the high cost of adding full-time staff.

Today, we provide estimating, preconstruction, bid management and business development support as an extension of our clients’ teams, helping them pursue more work and operate more efficiently.

Based in South Florida, TN Cost Group supports contractors nationwide.
