Our Work in Action: One Dalton

During the One Dalton project in Boston, the job of the belt truss, designed to span the 24th to 26th floor, was to control excessive drift due to lateral load and help minimize the risk of structural damage due to wind or earthquakes. It was a critical component to the high-rise and was critical to completing the building on schedule. Designed in 2D, the belt truss consisted of rebar that was meshed too tightly together, which would not have allowed the concrete to flow in between the bars. The Suffolk team had an intuition that the belt truss could not be built the way it was designed, and we used 3D modeling to prove that logic before construction started.
