a low pylon, cable-stayed structure. This method can save time, money, and space while minimizing disturbance of environmentally sensitive areas. The site posed numerous obstacles to construction progress, includ- ing seasonal weather extremes, ice flows, limited channel width, and a protected river basin. To overcome the hurdles and meet the project delivery deadline, the team had to accomplish key objectives: • rapidly build a bridge model within tight time constraints; • create a digital environment to manage and exchange all civil design in- formation; and • define a BIM strategy that enabled the 3D monitoring of incremental bridge launching. The clear solution was adopting BIM methodologies to manage the bridge construction effectively. Bentley provided the applications that Long Jian Road & Bridge required to perform the civil construction tasks, while also providing technical support and comprehensive solu- tions to the other construction units on the project. Long Jian Road & Bridge implemented Bentley’s platform for BIM- enabled construction management and trained personnel in BIM methodologies. The goal was to meet well-defined objectives for cost, quality, and safety while reducing material waste, deploying machin- ery effectively, and utilizing manpower efficiently. The project team researched and developed standardized 3D design modeling methods that enabled members to collaborate effectively. The design team leveraged OpenBridge Modeler’s 3D parametric modeling capabilities to achieve the required degree of accuracy for the bridge’s superstructure. The integration between OpenBridge Mod- eler and OpenRoads enabled precise positioning of the substructure and customization of more than 60 structures. As a result, the team improved efficiency by 50 percent compared with traditional methods by implementing parametric modeling tech- niques. Finite element analysis with RM Bridge simulated the pile foundations, main beams, and other structures to optimize structural strength, rigidity, and stability. Modeling steel structures and structural reinforcements with ProStructures helped to reduce material waste and construction rework, saving 30 tons of material. ProjectWise enhanced collaboration and coordination among the dif- ferent disciplines involved in construction of the bridge, roads, cul- verts, civil works, and related infrastructure. Together with MicroSta- tion, ProjectWise became the platform for 5D construction information management, creating a common data environment that allowed all participants to share, review, and update information in real time. This collaboration improved modeling efficiency by 35 percent and acceler- ated decision-making among management teams. MicroStation provided the comprehensive modeling environment that enabled 5D progress tracking, incremental launch monitoring, inspec-
tion and quality reporting, plus cost control. Real-time inspection review and approval allowed follow-up work to proceed quicker. The project team used Bentley Navigator to coordinate construction orders, reduce scheduling conflicts, and improve progress management. Visualizing reality Reality modeling with ContextCapture was instrumental in digital ter- rain modeling and site planning, as well as managing safety, security, and digital assets. The 3D reality mesh of the site was used to optimize earthworks and site utilization. LumenRT enabled the project team to create life-like visualizations for improved project understanding and communication with government officials and members of the public.
MicroStation’s comprehensive modeling environment was utilized during the design phase and enabled 5D progress tracking and quality reporting.
The project team used visualization capabilities to communicate complex working procedures and provide visual data. iModels, 3D PDFs and printing, construction simulations, and virtual reality ap- plications improved understanding of design intent, project progress, and desired outcomes. These capabilities were especially helpful when communicating with the many levels of management on each side of the China-Russia border. The visualization technology for technical project management decreased time spent on meetings and inspections and increased quality assurance. With fewer conflicts, construction Long Jian Road & Bridge leveraged Bentley applications to meet the dual challenges of a short construction period and a complex work- ing environment. BIM workflows allowed the management team to perform 25 percent more efficiently. The team also achieved benefits at each phase of the project, including accurate 3D models, optimal material quantity calculations, and efficient deployment of personnel and machines, which reduced rework and costs. progressed on schedule. Measurable returns Bentley applications optimized the bridge design, which will ensure that the structure fulfills its form and function goals, as well as achieve
