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 interoper - ability 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 plat - form to monitor construction of the Taihong Yangtze River Bridge, CRCTDG improved construction management quality and efficiency, eliminated the information silos and bottlenecks of conventional con - Project Summary Organization: China Railway Changjiang Transport Design Group Co., Ltd. Solution: Bridges Location: Chongqing, China Project Objectives: • Apply intelligent 3D BIM methodologies to streamline workflows and generate a single data source for lifecycle bridge management. • Simulate construction progress and achieve high- precision construction quality control. Project Playbook: ContextCapture, LumenRT, MicroStation, OpenBridge Modeler, OpenRoads ConceptStation, ProStructures, RM Bridge Fast Facts • The six-lane, 1,436-meter Taihong Yangtze River Bridge will cross the Yangtze River in Chongqing. • The team proposed methods for intelligent information management and collaboration. • Simulated construction monitoring and digital workflows streamlined communication and planning. ROI • ContextCapture and MicroStation reduced bridge design time by 300 hours, helping complete design 30 days early and save CNY 500,000. • Establishing digital construction management saved CNY 1.8 million in management costs and shortened construction by 47 days. • The virtual 3D model ensures quality and safety throughout the project and will promote the industrialization of Chongqing’s bridge infrastructure industry.
struction, 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 improved 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 simulated construction environment, as well as predicting and overcoming poten - tial 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, ensur - ing 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 infrastruc - ture have been truly enabled, which promotes industrialization of the infrastructure industry,” said Chen. With Bentley’s open applications, CRCTDG established digital workflows and a construction management platform that eliminated information silos caused by traditional construction methods.
