    Application of BIM Strategy on the Transformation of Meiguan Expressway to Urban Road Design Project

    Shenzhen, Guangdong, China

Project Summary

Project
CCCC First Highway Consultants was contracted to provide design consulting services for a CNY 9.4 billion Meiguan Expressway retrofit and expansion of an existing expressway. The expansion would span approximately 8.5 kilometers and included eight interchanges between the Meilin Inspection Station and Qinghu in Shenzhen, China. The design had to consider a complex environment – including 3,700 underground pipelines, eight grade-separated junctions, and heavy traffic – and be completed within nine months.

Solution
CCCC provided design services from planning through preliminary design and construction for the expansion of the original expressway and the newly built auxiliary roads. Due to the dense road network, heavy traffic flow in the project area, and a compressed design cycle, CCCC implemented a collaborative BIM approach, using Bentley applications to achieve the municipal engineering design in a 3D environment. The team then used exploration data to model the complex underground 3D environment.

Outcome
The use of Bentley applications to implement a 3D collaborative design workflow reduced rework, optimized information sharing, and saved design time. It also enabled project delivery to be 43 days ahead of schedule while reducing costs by CNY 2.2 million. In addition, CCCC saved on the design modification workload (estimated to be 120 days), the preliminary design review (estimated to be 60 days), and the pipeline design error inspection (estimated to be 150 days). The BIM model also allowed the team to carry out a construction simulation and virtual traffic mitigation, which will help the construction team minimize impacts on the community.

Software
The project team used Bentley’s integrated BIM applications and reality modeling technology, including MicroStation, OpenRoads, Subsurface Utilities Design and Analysis (SUDA), and OpenBridge Modeler for parametric 3D design in all directions. The reality mesh, combined with a 3D geographical model, provided a real and intuitive design basis, making the design scheme more accurate, reasonable, and economic. The team also used ProjectWise as the common data environment to manage, store, and share information among the different design disciplines and stakeholders.
