Project overview
A substantial steel package across multiple alpine buildings.
Big Springs Village Phase 2 is a 420,000-square-foot mixed-use development at the base of Yellowstone Club in Big Sky, Montana.
The project comprises Buildings 5, 6 and 7, a Central Utility Plant, 35 residential condominiums and associated amenities and support spaces.
Working with Allied Steel, Anatomic provided structural steel detailing across the residential buildings and Central Utility Plant.
The scope included complex multi-slope roofs, specialized seismic connections and extensive coordination with architectural wood and stone fascia.

Detailed Model
Steel ConstructionTECHNICAL COMPLEXITY
Coordination and detailing challenges.
Seismic and gravity framing interfaces
Special Moment Frame connections formed part of the Seismic Force-Resisting System, requiring coordination with the surrounding structural framing.
Specialized BRB connections
Buckling-Restrained Brace frames introduced additional connection detailing requirements within the project's seismic system.
Architectural fascia coordination
Extensive wood and stone fascia required coordination between structural steel and architectural elements across the buildings.
STEEL DETAILING
Specialized connections within complex alpine roof structures.
The detailing process brought together skewed roof framing, Special Moment Frame connections and Buckling-Restrained Brace connections within a coordinated steel package.
Across the residential buildings and Central Utility Plant, Anatomic also coordinated steel interfaces with extensive architectural fascia systems, including wood and stone finishes.
These overlapping structural and architectural requirements made accurate connection detailing and interdisciplinary coordination central to the project.
