1400 Monroe is a seven-story condominium building in the heart of Chicago’s West Loop neighborhood. The development includes forty-two luxury residences above the ground-floor lobby and parking. SGH is the structural engineer for the building, constructed with prefabricated, load-bearing steel stud wall and floor panels supported on a steel-framed podium.
SGH collaborated with the project team, including Booth Hansen, the architect, and Summit Design Build, the general contractor, to design the structure. Highlights of our work include the following:
- Developing options for below-grade structural systems to accommodate the parking needs while minimizing excavation
- Designing the structure, including the steel-framed podium, concrete masonry unit shear walls, and reinforced concrete ComEd vault and water-detention tank
- Coordinating with specialty consultants and fabricators for the prefabricated, cold-formed steel wall and floor panels to design transfer framing within the cold-formed panels to accommodate custom unit layouts and clear span requirements
- Designing recessed and hung steel balcony systems integrated with the cold-formed framing system
- Designing private roof deck structures with outdoor kitchens, trellises, and access stairs
- Providing construction-phase services, including reviewing contractor submittals, visiting the site to observe ongoing construction, and helping the project team address field conditions
