MBTA Kendall/MIT Station Entrance

Scope/Solutions

As part of the Kendall Square Initiative—a collaborative development created by the Massachusetts Institute of Technology (MIT) and private partners—the MBTA Kendall/MIT station was upgraded with a new headhouse designed to improve accessibility and serve as a gateway to the east side of MIT’s campus. Visitors exiting the station will be oriented by a 160 ft long canopy that points toward the famous Infinite Corridor. SGH served as the structural engineer of record for the canopy and headhouses.

The design was driven by a desire to create a feature icon with a sleek canopy and slender columns. SGH collaborated with Perkins&Will on the design. Highlights of our work include:

  • Consulting on early concepts and material options, including stone and titanium, porous aluminum, and fiber-reinforced polymers (FRP)
  • Using machine learning (supervised linear regression) to evaluate more than 200 million options for the complex canopy geometry to achieve the fewest and thinnest possible columns, considering the interrelated behavior between the column locations bounded by existing site conditions and the stiffness of the roof
  • Providing structural layout options to the architect via a web-based program that we developed at SGH to help us present complex three-dimensional solutions
  • Designing the FRP canopy structure on slender steel columns with strategically located bulkheads to stiffen the roof
  • Collaborating with the project team, including a boat builder in Maine who fabricated the canopy in two halves and transported it by barge to Cambridge, Massachusetts
