Van Winkle Stadium & Lambert Field

TD&H provided design, a traffic study update, and construction administration, along with design and construction for a new field complex at the Lambert Fields on the MSU campus.

Great Falls Water Treatment Plant

This project won the American Council of Engineering Companies of Montana Grand Project Award Winner (2019).

Briarcliff Fire Station

TD&H seamlessly integrated concrete foundations, CMU shear and bearing walls, long-span open-web steel joints, and a wood-framed mezzanine structure into the 6,000 sq. ft. addition to the Briarcliff Fire Station.

Peasley Creek Fish Passage Bridge

The project was to improve fish passage by replacing an existing box culvert and complete construction during the fish window. The project, funded jointly by the U.S. Forest Service and the Nez Perce Tribe, replaced the existing box culvert with a larger-span pipe arch.
