Collaborative BIM Workflows Help Lower Cost of the Zhengzhou-Xixia Expressway Project

The expressway project team faced a variety of challenges to ensure the accurate design of the model and used Bentley’s civil applications to include subgrade roads, bridges, tunnels, and culverts within one model and ensure collaboration across all disciplines in highway design.

OpenRoads was used to build a 3D model defining the cross sections of roads and importing data related to horizontal and vertical sections. The project team also used the model for bidding. OpenBridge Modeler was used to build parametric models for bridges with higher efficiency than past work processes. ProStructures was used for models for steel bars in bridges and to detect collisions and errors in design, decreasing the number of errors...
