Marquee at Block 37
Delivered through the Design/Build methodology for developer and owner CIM Group, the Marquee at Block 37 apartment tower is the realization of the final component to the existing mixed-use retail, office, and transit station development at Madison and State in Chicago.
The 767,000-square-foot complex occupies an entire city block in the heart of the State Street retail corridor in Chicago’s Loop. Built above the existing retail mall and subway transit line, the tower consists of 41 floors housing 691 apartments. Building amenities include a large outdoor pool, spas, steam and sauna facilities, cabanas, grill terrace, fire pits, and outdoor cinema projection. Indoor amenities include fitness club room, lounge, game room, party room, cinema, and library. The fitness, spa, steam, sauna and fire pit lounge are located at the top of the tower, offering residents stunning views of Lake Michigan and the cityscape of the downtown business district.
The site’s existing conditions posed significant design challenges. The east third of the tower is built over an existing, column-free, below-grade loading dock. To achieve building a tall tower without the usual foundation-level support, SCB’s design used four 27-foot high by 90-foot long steel trusses. The high-strength steel was manufactured in Luxembourg and then cut and milled in Green Bay, Wisconsin. The pieces were then trucked to Chicago and built on-site with bolted connections. The central third of the tower is built with conventional concrete, while the west third lies over a future high-speed rail tunnel. Due to the unique angle of the tunnel and clear span requirements, the concrete structure at the fifth floor is comprised of a six-foot transfer slab.
Another challenge derived from the original development brief, which allowed for a mixed-use hotel and residential tower. The brief called for ground floor shuttle elevators to transfer between floors of the respective hotel and residential tower lobbies, thereby limiting the area allocated for the ground floor lobby. In contrast to the existing brief, CIM Group required an all-residential program, with all levels to be accessed directly from the single, under-scaled ground floor lobby. SCB’s design team was charged with maximizing the allowable 900 units without use of a skylobby. SCB’s solution achieved 691 units, ultimately hinging on elevator configuration to maximize entitlements.
