Our History


The evolution of TCA Group

The first bridge Greg Benjamin and Keevin Stanhope worked on together was the Martinsdale Bridge, which was constructed for Fish Wildlife and Parks in 1998. This bridge is located on Martinsdale Lake Road about ¼ mile east of the Town of Martinsdale, Montana. The bridge crosses an irrigation canal that supplies water to the Martinsdale Reservoir. At this time Keevin was working for Tracey Cowdrey and Associates and Greg Benjamin was working for Stahly Engineering & Associates. TCA, Inc has been bidding and constructing bridges designed by Stahly Engineering & Associates on a regular basis ever since.


Combining the construction services of TCA Group with the design services of Stahly Engineering & Associates provides our clients and industry with quality, efficient and sustainable services that provide value for years to come.


Building positive relationships by delivering quality services is the key to our success. Personal involvement from owners and project managers in individual projects performed and the communities we serve strengthens our commitment to our clients’ goals.


Stahly Engineering has completed design and construction administration on over 50 bridges in the last 10 years. Our bridge team has become a valuable asset to many Montana County road and bridge departments, assisting with preparation of bridge inventories, inspection of bridges, management of emergency bridge replacement, funding, design, and construction inspection. Keevin and TCA have been performing bridge construction since 1995 and have been teaming with Stahly on bridge projects since 1998.


TCA Group provides a bridge building operation and expanded services into a market sector in which Stahly Engineering has established relationships.
