Great Falls


The Great Falls office was formed in 1991 as NTL Engineering & Geoscience, Inc., an employee-owned Montana corporation practicing in the geotechnical, construction materials, and environmental engineering and testing fields. NTL joined Terracon in 2008 and officially changed its name to Terracon in 2013. The Great Falls engineering staff have a wide range of geotechnical experience on projects ranging from large industrial facilities to dams, bridges, highways, landslides, rockfalls, retaining structures, defense facilities, and seismic-related studies with geographic project involvement ranging from Wyoming to Alaska. We provide construction materials engineering/testing and QA/QC services for projects ranging from buildings and pavements to earth structures. In-house testing services include determination of soil/aggregate index and engineering properties, Portland and asphaltic cement concrete mix designs and related testing, along with field quality control services during construction.
