to regularly collect site data during construction to record project construction at different construction periods,” commented Chen. Using LumenRT, CRCTDG integrated the reality and BIM models to simulate the construction process and monitor progress, optimizing construction through effective planning. With Bentley’s open applications, CRCTDG established digital work- flows and a construction management platform that eliminated infor - mation silos caused by traditional construction methods. The interop- erability of MicroStation helped streamline and integrate models from multiple applications, providing a single data source throughout the project lifecycle. By employing iModels, they enabled digital delivery and a cloud-based platform, resulting in mobile review and enhanced cost control. The digital workflow allowed them to combine construc - tion process data with the BIM model to achieve high-precision con - struction quality control and create a unified, intelligent bridge model that can be used through operations and maintenance. Industrializing Chongqing’s Bridge Infrastructure Industry By establishing a 3D BIM-based construction management platform to monitor construction of the Taihong Yangtze River Bridge, CRCTDG improved construction management quality and efficiency, eliminated the information silos and bottlenecks of conventional construction, and established lifecycle BIM operations and maintenance. Having a visual representation of the project provided all participants with an experience that simulated being on site, regardless of their location. The improved visualization helped reduce the time spent traveling to the site by 23 days, as well as optimized planning and scheduling. Through parametric modeling and automated processes, they im- proved design efficiencies, reducing bridge design time by 300 hours and saving CNY 500,000. Establishing digital workflows streamlined communication and collaboration to help complete the bridge design 30 days ahead of schedule. Bentley’s solutions provided dynamic digital management of construc- tion planning and resource allocation to effectively carry out progress control and lower construction costs. Working in the digitally simu- lated construction environment, as well as predicting and overcom- ing potential problems in advance, saved nearly CNY 1.8 million in construction management costs and shortened the construction period by 47 days. Applying BIM modeling methods, CRCTDG established a 3D digital context to clearly communicate the development process and manage engineering information throughout the entire project lifecycle, ensuring quality and safety. The complete visual model lays the foundation for the intelligent manufacturing and construction management of similar large steel bridge projects. “[Using Bentley applications], lean construction, precise management, and control of modern infrastructure have been truly enabled, which promotes indus- trialization of the infrastructure industry,” said Chen.
