Legends 267
Kansas City, KS
Legends 267 is a mixed-use residential development located in the heart of the Legends district of Kansas City, Kansas, adjacent to the KC Sporting Soccer Complex and the Kansas Speedway. The project consists of a five-story cold-formed steel (CFS) load-bearing structure constructed over a three-story precast parking garage. The residential portion spans approximately 300,000 square feet and houses 267 units, while the 240,000 square foot garage provides ample parking for residents and visitors.
McClure served as the engineer of record for structural and specialty CFS design, working closely with Rosemann & Associates Architects and the full project team. One of the primary challenges was designing a CFS system that could effectively transfer loads to a precast podium—without relying on more costly concrete or CMU lateral systems. McClure performed iterative analyses to optimize the CFS strap-braced shearwall layout, reduce point loads, and coordinate with the precast engineering team to ensure compatibility with double-tee construction tolerances and camber.
Innovative detailing was required to resolve misaligned structural elements between the residential units and the garage below. Custom embed and base plate solutions were developed to safely handle punching shear and uplift forces while maintaining constructability and aesthetics within finished living spaces. Additionally, McClure designed connections that allowed the lateral forces from the CFS shearwalls to transfer through the podium diaphragm and into the precast shearwall system via topped slabs and headed studs. The resulting design not only met structural demands but also demonstrated how cold-formed systems can be successfully integrated above precast podiums, setting a precedent for future multifamily developments.

Highlights
- Performed iterative analysis to reduce CFS shearwall loads on the precast podium and accommodate camber tolerances
- Analyzed garage for deep-buried lateral forces from soil pressure in addition to wind and seismic loads
- Led coordination across precast, CFS, and balcony design teams to align with owner-selected construction types
- Provided extensive construction administration to support complex system integration
- Coordinated design of a connector bridge between the new and existing garages, addressing elevation and foundation constraints
