Originally built in 1938, the existing East 138th Street Bridge is being replaced to eliminate vertical clearance issues and optimize vehicle and pedestrian traffic demands. NYSDOT wanted to use a digital twin as the primary construction document. Located in a heavily congested area, the team needed to create the construction sequencing plan and accommodate existing utilities, compounded by COVID-19. They needed a hybrid modeling approach to generate a digital twin of the complex superstructure and pedestrian components.Already familiar with Bentley applications, they used OpenBridge Modeler, OpenRoads Designer, and ProSteel to generate an accurate 3D model. iTwin Design Review provided a central platform for over 180 reviewers. Bentley’s integrated technology helped identify and resolve costly issues prior to construction. SYNCHRO 4D facilitated visual, dynamic construction sequencing and traffic control planning for better project coordination. The digital twin is a tool for asset management and bridge inspection.
