ground development. With OpenBridge, the design team strengthened the founda- tions of bridge piles, while OpenBuildings was leveraged to restore all aspects of the subway system affected by construction. A Single Source of Truth Saves Time and Money Teams from numerous disciplines col- laborated in ProjectWise to ensure a single source of truth. Individual models were brought together in LumenRT to form a digital twin that visualized all elements of the project. Though design teams worked in different file formats, CUCIMG used the interoperability of Bentley applications to seamlessly combine all contributions into
a single format. Compared to traditional 2D modeling, 3D visualization helped the design team improve designs and work efficiency. Additionally, the efficient visual twin presentation improved loading times and lessened hardware re- quirements compared to CUCIMG’s late-stage BIM presentations during past projects. The design team incorporated all necessary asset information for construction, operations, and maintenance into a digital twin, which is expected to extend the lifecycle of all assets. By collaborating within ProjectWise, CUCIMG improved the design management process and increased internal work efficiency by 20 percent. ProjectWise also helped CUCIMG to detect and resolve 16 design clashes within the pipeline system. Automated design within OpenRoads reduced the construction drawing time by 120 resource hours. By us- ing the digital twin to guide the construction process, the design team shortened the time required for planning, construction, and approval by 15 percent. Work with the digital twin determined that building the foundations of the elevated road and the underpass tunnel simultaneously would prevent problems during construction. In total, CUCIMG’s work with 3D modeling lowered design costs by 23 percent and construction costs by 10 percent. Project Summary Organization: Chengdu Urban Construction Investment Management Group Co., Ltd. Solution: Digital Cities Location: Chengdu, Sichuan, China Project Objectives: • To design a CNY 1.38 billion infrastructure package, including 4.3 kilometers of new roads. • To improve efficiency by incorporating BIM techniques throughout the design process. Products Used: ContextCapture, Descartes, gINT, LumenRT, MicroStation, OpenBridge, OpenBuildings, OpenRoads, ProjectWise Fast Facts: • The CNY 1.38 billion infrastructure redevelopment project included building 4.3 kilometers of new roads, pedestrian paths, and underground infrastructure. • Building within the dense commercial area required minimizing the impact of overpasses on buildings and constructing tunnels two meters away from a subway line. • To manage the complex project, CUCIMG leveraged 3D modeling throughout the design, which was a first for the organization. ROI: • 3D visualizations of all project assets helped determine where to place bridge supports and how to connect 64 roads designed for varying speeds. • A connected data environment improved work efficiency by 20 percent, detected and resolved 16 design clashes, and reduced drawing time by 120 hours. • Overall, 3D modeling applications helped lower design costs by 23 percent and construction costs by 10 percent.
