Project
As part of the ecological restoration and urban repair in China’s Sanya City, Tianjin Municipal Engineering Design & Research Institute (TME) was awarded the CNY 1.235 billion engineering, procurement, and construction (EPC) contract to retrofit a 9.42-kilometer municipal road in Haitang Bay. The road project includes bridges, culverts, drainage, water supply, comprehensive pipe rack, and other works. TME needed flexible, collaborative technology to efficiently coordinate design and construction among the multi-discipline project team as it faced complicated terrain and geological challenges requiring complex engineering analysis and technical solutions.
Solution
TME leveraged Bentley modeling applications to implement a collaborative building information modeling (BIM) approach. ProjectWise was used to manage and coordinate the multiple disciplines and reality modeling and point clouds for better visualization and more intuitive communication. TME effectively analyzed pipeline collisions, more accurately calculated earthwork and material quantities, and efficiently solved conflicts with Bentley’s flexible, integrated capabilities to optimize design and construction.
Outcome
Working in a collaborative 3D environment helped avoid pipeline collisions, saving CNY 600,000; avert a 15-day construction delay, saving CNY 2 million; optimize raw water transmission line design, shortening design time by one month; avoid an emergency shutdown, saving CNY 3 million; and adjust a pipeline procurement scheme, saving CNY 10 million. Using reality modeling software saved travel costs and accelerated earthwork measurements while ProjectWise facilitated information mobility, streamlined workflows, and enabled real-time optimization of design schemes. Using Bentley technology, TME delivered the project one-and-a-half months ahead of schedule.
Software
Using MicroStation and PowerCivil, TME performed comprehensive cross-collision analyses of the pipe rack and pipelines to resolve difficult design problems, reducing design time by 30 days. With the help of gINT, the team provided timely solutions to underground box culverts and covered drain issues to save construction time. The precise modeling capabilities of Bentley Subsurface Utility Engineering (SUE) and HAMMER helped avoid an emergency shutdown while OpenPlant controlled cutting and material costs of steel plates. Bentley’s point cloud applications and reality modeling capabilities enabled better understanding of the entire project, improving design efficiency by 20 percent.
