Structural Engineering

Seeley Building in Helena, MT

Slate Architecture and Stahly Engineering structural staff have partnered on this large residential building project in Helena, MT.


Montana City School

Stahly Engineering served on a multi-disciplinary team providing professional design services for the Montana City School expansion which included an extensive lobby area and 8 additional classrooms. This project was completed on an accelerated timeline made possible by consistent involvement of the design professionals and contractor.

Parking Garage at Broadway and Cruse

A thorough evaluation of the parking garage at Broadway and Cruse, owned by the State of Montana and managed by the Department of Administration, was conducted by structural engineers at Stahly Engineering. The structure's deficiencies included drainage issues which had compromised concrete and steel members of the structure. Following the recommendations of Stahly Engineering, the Department chose to remove and replace the entire concrete deck and adjust steel beams to improve future drainage. The construction project was administered by Stahly Engineering.

Dept of Military Affairs Rappelling Tower

The Department of Military Affairs utilized Stahly Engineering for structural design and construction inspection of a Range Air Assault Tower at Fort Harrison. The Tower is a 55 ft tall concentrically braced steel tower that provides climbing, FastLine, and rappelling training for the military's special forces units.  Click here for a video of the tower in use!
