2017 NCSEA Excellence in Structural Engineering Awards
Project Category: New Buildings under $20 Million

Designed as the shining new heart of Boston’s Financial District, The Exchange at 100 Federal Street is a structural steel and glass pavilion that will function as a public gathering and event space, delivering a contemporary addition responding to the form of the existing 37-story, 1971 office building. The angular volume is a solid steel space frame with exposed bolted connections, where honest structure is celebrated, and shape and detailing were carefully considered for efficiency. This project highlights the benefits of collaborative design loops, integrating owner, design, and construction teams to activate a pedestrian commuter thoroughfare with a landmark structure.

The structure for the steel frame is entirely solid plate steel, ranging from 28”x4” to 12”x1.25”, with exposed side plated, field bolted connections. It rises from 35ft tall at the main entry to over 50ft tall at the highest point, leaning 10ft out over the plaza.

The Exchange will be featured in an upcoming Structure magazine article and will be opening to the public in the spring of next year.
