Project
The 27.9-kilometer main channel road of the Ningbo-Zhoushan Port is part of a CNY 16.8 billion marine infrastructure project in China’s eastern city of Zhoushan to improve transportation and promote rapid development of the regional economy. Tianjin Tianhe-Cloud Building Engineering Technology is responsible for implementing BIM processes and China State Construction Bridge is responsible for construction. Faced with structural and technical complexities on a short construction schedule, amid extreme weather conditions and site constraints, the organizations required integrated 3D BIM design and construction analysis technology to deliver this large-scale offshore construction project.
Solution
The companies formed a professional team to carry out a BIM methodology using Bentley modeling and management applications. Using OpenBuildings Designer, MicroStation, Navigator, and Bentley’s civil and structural analysis applications, the team created a 3D model and performed collision analysis and construction simulation. Reality modeling technology was used for construction verification to ensure accuracy, while ProjectWise provided the collaborative management platform facilitating dynamic real-time communication among all project participants. Bentley’s integrated digital solution established a comprehensive 3D BIM strategy, driving intelligent construction for what is set to be the world’s largest deep-sea spanning bridge project.
Outcome
Bentley BIM technology resolved 120 drawing problems and 624 collisions prior to construction. Using Navigator and MOSES for construction simulation optimized the construction plan, saving nearly CNY 5 million in costs and accelerating construction progress by 10%. Bentley’s interoperable modeling and analysis applications improved design reliability, eliminating safety risks and promoting quality construction. The software’s visualization features streamlined construction processes, optimizing scheduling and planning to increase construction efficiency by 20 percent. Having a 3D collaborative BIM model and working in an open, connected data environment dramatically reduced paper resources and meeting times.
Software
The BIM team used OpenBuildings Designer and MicroStation to create a fundamental 3D model of the project. OpenBridge Modeler was used to model the bridges while SACS was instrumental in performing structural analysis to ensure the infrastructure could withstand the extreme weather and geological conditions in the offshore environment. ProStructures facilitated design and reinforcement of concrete structures enabling the team to achieve zero rework cutting the prefabricated reinforcing steel bar. Using LumenRT to render animated visualizations of the 3D model enhanced communication of deliverables to the project owner. ProjectWise established a connected digital 3D BIM environment to optimize information sharing and increase productivity.
