Project overview
Structural steel detailing across multiple building levels and uses.
Cache & Pearl is a three-story mixed-use development in downtown Jackson, Wyoming, combining ground-floor retail and parking with 18 residential units above.
The building also includes a basement, rooftop deck, pool, and spa.
Working with Allied Steel, Anatomic modeled and detailed the structural and miscellaneous steel package using Tekla Structures. The scope included complex seismic connections, design-assist steel, and extensive coordination across changing slab elevations.

DETAILING SCOPE
Structural and miscellaneous steel across a mixed-use building.
Seismic and special connections
HSS braced-frame connections, yield gusset plates, moment-welded connections, and special braced-frame connections within the Seismic Force-Resisting System.
Design-assist light structural steel
Development of light structural steel details in coordination with the engineer and architect.
Six stair towers
Steel stairs, landings, and railings, plus an additional two-flight stair with a gate.
Deck and elevator coordination
Coordination of steel interfaces with deck and elevator suppliers.
Thermal break connections
Detailing of connection conditions incorporating thermal break bearing pads.
TECHNICAL COMPLEXITY
Coordination and detailing challenges.
Multiple slab elevations
Changing floor levels created complex relationships between structural framing, connections, stairs, and adjacent building systems. These conditions required accurate three-dimensional coordination.
Seismic connection interfaces
The project incorporated several specialized connection types associated with the seismic system. Their geometry and detailing requirements had to be coordinated with the surrounding steel framing.
Stair towers across changing levels
Six stair towers, complete with landings and railings, required careful coordination of stair geometry, support conditions, and floor elevations.
Design-assist and supplier coordination
Model exports supported collaboration with the engineer and architect as the design-assist scope developed. Coordination with deck and elevator suppliers helped resolve interfaces affecting fabrication and installation.
OUR APPROACH
Model-based coordination from design development to detailing.
Tekla Structures was used to model the steel package and support coordination with the wider project team.
Model exports helped the engineer and architect review developing conditions, particularly where changing slab elevations and specialized connections affected other building elements.
The coordinated model also provided the basis for fabrication and erection information.
