Triangle Square is a 298-unit residential apartment complex located in Chicago’s Bucktown neighborhood, just west of downtown. The east-facing luxury units feature uncovered terraces with panoramic views of the city skyline. The building consists of six stories of cold-formed steel (CFS) framing atop a one-story concrete podium. The structural system uses C-stud joists spanning between demising walls, supporting a gypcrete-over-metal deck floor system. A signature sloped roof and nonorthogonal geometries—both horizontal and vertical—added architectural complexity, requiring the building to be divided into five distinct structural analysis zones.

The design incorporated masonry stair and elevator cores paired with cold-formed steel strap-braced walls to provide lateral stability. McClure played a critical role throughout the project, providing early design coordination, load calculations, and detailed structural steel design, including embed layouts and drag strut connections. Leveraging 3D structural modeling and BIM, McClure successfully aligned the building’s continuous staircase and resolved intricate geometries involving non-stacking headers and posts.

During construction, McClure addressed several field challenges, including reinforcement of wall studs and precise alignment of strap-braced wall end posts with structural embeds, helping ensure structural integrity, code compliance, and overall project success.
