When the Minnesota Department of Transportation received funding to transform TH 169 into a freeway system, they retained WSB to oversee the final design. The project included converting four traffic intersections into interchanges, relocating utilities, and designing roadway, drainage, and bridge elements. With complicated earthworks and construction costs capped at USD 130 million, WSB needed a flexible, iterative design process and accurate material quantity takeoffs.

WSB selected Bentley’s open modeling, visualization, and construction simulation applications to help save the client over USD 4.8 million. Performing clash detection saved 18 months in relocating utilities, while synchronizing the 3D model with 4D construction scheduling identified potential conflicts, accelerating construction activities by three months to save USD 485,569. Using the Bentley iTwin platform to create digital twins early in the engineering process facilitated collaboration that supported seamless data and model integration throughout construction and operations.
