Structural SteelApproximately 1,260 tons
Project overview
Structural steel detailing for a major airport expansion in Montana.
The East Terminal Expansion responds to growing passenger traffic at Bozeman Yellowstone International Airport. The multi-phase project includes Concourse A, baggage claim, passenger screening and airport administration areas.
Inspired by Montana’s mountain lodges, the terminal combines steel, timber and concrete with expansive glass curtain walls offering views of the Bridger Mountain Range.
Working for WMK & Co., Anatomic provided structural steel detailing for approximately 1,260 tons of steel. The Tekla Structures model included steel columns supporting composite steel and glulam beams, extensive vertical bracing and tube steel framing for the curtain wall system.

Technical complexity
Coordinating new steel with existing CMU and extensive glulam framing.
Extensive steel-to-glulam coordination
Changes in steel or timber information required ongoing coordination to maintain compatible member positions and connections.
Glass façade support alignment
Tube steel framing had to satisfy curtain wall requirements while remaining coordinated with the primary structural steel.
Frequent design revisions
Connection modifications and member-position changes continued during detailing, requiring continual model and drawing updates.

Project delivery
A successful project delivered for the first phase of the airport expansion.
The structural steel detailing scope was completed for the 2025–2026 phase of the project.
The broader East Terminal Expansion is a multi-phase investment currently projected for completion in 2030. Preparations for phase 2 are underway.
