    Construction and Design General Contracting of Retrofit Project at Haiyu East Line Municipal Road, Haitang Bay

    Sanya, Hainan Province, China

Project Summary

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.

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.

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.

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.

  • TME optimized design and construction of Sanya City’s CNY 1.235 billion roadway project in Haitang Bay, China using Bentley’s integrated technology to implement a collaborative approach, saving millions in design and construction costs.
  • Bentley’s flexible, interoperable modeling and analysis capabilities improved overall design efficiency by 70 percent, saving nearly CNY 1 million in design costs.
  • Leveraging Bentley applications reduced procurement costs by CNY 10 million, saved CNY 2 million resolving an emergency issue, and shortened the construction period to save CNY 3 million in construction costs.
  • Reality modeling reduced travel costs by CNY 100,000 and design time by 15 days.
  • Implementing a coordinated BIM approach with ProjectWise as the collaborative platform accelerated accurate information mobility among the 20 different disciplines.
  • “Bentley’s software for civil infrastructure has incomparable advantages in the design and construction of municipal roads and pipe rack engineering. It can provide one-stop solutions that can express the design intention in a better manner, improve design efficiency, and reliably solve the problems faced in the construction process.”
