Colorado DOT will provide roadway improvements, enhancing safety and reducing crashes along an eight-mile section of the I-70 corridor near Floyd Hill that is prone to severe congestion and bottlenecks. AtkinsRéalis is the lead designer and faced site constraints and challenging topography while needing to minimize the impact to environmentally sensitive areas and existing roadways. They also faced a complex design compounded by coordinating multiple disciplines and stakeholders. To address these challenges, Atkins needed integrated digital technology.

AtkinsRéalis utilized iTwin to create digital twins to gain visibility, Bentley’s open modeling applications to facilitate collaborative modeling and data management, and LumenRT for visualization. Working in a connected digital environment with ProjectWise saved USD 1.2 million managing more than 1,000 file sheets, 5,500 hours in coordination time, and 97% of effort developing and publishing digital twins for review. Atkins could clearly convey design intent, foster community integration, and quickly update models to mitigate environmental and social impact.
