For one of New York’s most overcrowded schools, MBB leveraged the flexibility of structural steel to create a 97,000-square-foot addition to house new classrooms, a gymnasium, and two cafeterias for nearly 2,000 students.

Despite its scale, complexity, challenging site, and high-performance features, the 67-story project is moving ahead of schedule and under budget. Partners on the project attribute this achievement to tight coordination, a steel-first sequence, and an all-star design and construction team.

The original Tappan Zee Bridge, revolutionary in its day, was well past the end of its operational life. Its challenging site called for structural creativity, a modern cable-stayed design, and careful environmental precautions.

With a broad brief for a cultural facility the DSR/Rockwell team enlisted top notch collaborators to produce a muscular, fine-tuned kinetic structure. Its steel-ETFE combination combines high performance and striking aesthetics.

Rockefeller University's new state-of-the-art laboratory facility was assembled in 19 midnight installments as 19 prefabricated steel modules were transported across the East River.

Acting as a threshold to the museum's recent expansion, the stair's minimal expression was achieved through structural innovation that allowed a vertical steel spine to hang from the roof structure to support stairs and landings without lateral bracing.

A collaboration between SHoP, ARUP, and Ken Smith Workshop extends open space to an urban porch at Pier 35 on the Lower East Side of Manhattan.

Heatherwick Studio's nickname-garnering form gives visitors a variety of superb views, a slight risk of vertigo, and a workout. Its design and construction team solved tricky problems of rigidity, safety, and buildability to create an urban mini-environment where visitors can climb into a realm of surprise.
