The Marina Bayfront Pedestrian Bridge in Singapore is the first of its type in the world. At 280 meters long, the bridge features a unique double-helix exoskeleton constructed from stainless steel, which gives structural support to a six-meter-wide deck spanning 65 meters between piers. By balancing the unraveling forces of the opposing helices, the bridge is being constructed out of significantly less steel.

The central workflow featured a streamlined flow of information between various packages used in the design process. Bentley’s GenerativeComponents allowed the Arup team to begin modeling the complex detail geometry even before the final geometry was finalized. Import/export facilities of the software allowed Arup to analyze the geometry in a number of ways and provide accurate information to internal and external parties in an an easy-to-undestand format. Other software deployed included MicroStation, InRoads, and Bentley Structural.
