The Second Wuhu Yangtze River Highway Bridge under construction in Wuhu, China includes a 13-kilometer-long bridge, with extensions of 23 and 21 kilometers on the north and south banks respectively. The bridge is the world’s largest assembly of whole steel beam sections and the longest cable-stayed span with four cable planes. With a short construction schedule and tight budget, 3D modeling and BIM methodologies were crucial to enable the efficient design and construction of this unique and complex project.
Anhui Transport Consulting & Design Institute used Bentley’s 3D bridge solution for visual designs and reviews. Using MicroStation and GEOPAK the design team overlaid digital elevation models (DEM) on satellite images so that they could select and determine bridge construction schemes. The 3D modeling environment enabled all project participants to exchange data efficiently and communicate effectively. This also enabled the consultation and review departments to clearly understand the design and control key project milestones. They then modeled the construction to avoid the risks and difficulties of building such a complex project.
Using Bentley 3D modeling software, Anhui Transport Consulting & Design Institute was able to design and review 20% more efficiently, which shortened design delivery time by eight weeks. The resulting 3D information models should reduce operation and maintenance costs by USD 2 million. The MicroStation-based 3D information management system enabled the efficient searching and sharing of information, reducing project management risks.
The team used Bentley 3D design software applications including GEOPAK, MicroStation, and RAM to design and model the bridge and extensions. Using MicroStation, they created a customized 3D information engineering management system to improve efficiency and optimally allocate resources. ProjectWise provided a collaborative environment and helped provide clear workflows, while also enabling control and management processes that reflected the project progress.
