Our Process

Why We Build Bridges, TCA and the Relationship with Stahly Engineering

Over the past decade, several bridge construction company owners in Montana have retired and closed their businesses. As a result, there has been a reduced number of experienced bridge Contractors serving the Montana County bridge market. The unfortunate result is less competition for projects – which contributes to inflated costs to County bridges, causing increased financial challenges for many Counties. Stahly Engineering saw this happening and, with the best interest of the Counties and the public in mind, decided to contribute to the solution.


Stahly established The TCA Group, LLC to transition TCA, Inc.’s operations and equipment to a long-term sustainable bridge construction company to serve the public bridge sector, specifically Montana Counties and off-system bridges in rural Montana.


TCA Group opened at the end of 2021 with a plan for acquiring the assets and hiring the experienced team at TCA, Inc. - TCA, Inc.’s roots were from Tracy Cowdrey and Associates. TCA Group is the steward of equipment, labor resources, construction materials, knowledge, and 20 years of experience from TCA, Inc. Our mission is to continue long-­term construction services for Counties and off-system/rural bridges throughout Montana.


Stahly Engineering became a 100% Employee-Owned business (ESOP - Employee Stock Ownership Plan) in 2020. TCA Group is a separate entity owned by the Stahly ESOP. Greg Benjamin serves as the President and CEO of both companies and is committed to the highest ethical performance of professional duties.

Collaboratively creating high quality, high value project delivery

Traditional Design/Bid/Build

Design/Bid/Build is a traditional project delivery method in which the owner hires an engineer and contractor separately to complete a project. 

There are three main sequential phases to the design–bid–build delivery method:

  • Design phase

  • Bidding phase

  • Construction phase


In this process, a single contractor is in charge of the design and construction of the structure. The engineer, Stahly Engineering, and contractor, TCA, work together from the beginning, as a team, providing unified project recommendations to fit the Owner's schedule and budget. Any changes are addressed by the entire team, leading to collaborative problem-solving and innovation.

Subcontract to Counties

TCA Group leverages their relationships  to deliver projects in a unique way through a non-traditional project delivery method. A recent bridge replacement consisted of partnering TCA Group's resources with the availability of the local County Road and Bridge construction crews.


GC/CM Project Delivery

General Contractor/Construction Manager (GC/CM) delivery methods can give TCA Group and it's clients the option for one project at a time or Term Contract model for multiple bridges over multiple years. This project delivery method is beneficial for complicated or long-term construction projects.


Alternate project delivery

Utilizing alternative project delivery methods with an emphasis on term contracts for multiple bridges enables planning for efficient construction with cost savings that benefit the Owner through lower construction costs.
