Project Summary



Project
Chengdu City in China has recently seen a dramatic population increase due to a recent economic revitalization. As a result, the local water supply capacity could no longer meet the expanded water demand of 400,000 tons per day. To meet this need, the government determined that constructing a large-scale water supply plant was essential. MCC Capital Engineering & Research Incorporation Limited was retained on an engineering, procurement, and construction contract for the Jinqiang Shouan Water Plant. This CNY 350 million water plant includes 23 facilities, and the project required collaboration among engineers from 12 distinct specialties. The Chengdu government wanted to ensure that the new water plant would have the least possible negative impact on the environment due to the nearby Wolong National Nature Reserve and the Chengdu Research Base of Giant Panda Breeding.

Solution
MCC implemented a collaborative 3D digital design strategy using Bentley’s building information modeling (BIM) applications to provide a solution for the intricate piping system and pool structure and multidiscipline project team. Bentley’s Connected Data Environment based on ProjectWise enabled collaboration among all team members and facilitated a flow of information among all the design specialties. MCC used OpenBuildings (formerly AECOsim Building Designer) and OpenPlant applications plant and building design software to layout the water facility plant using Bentley’s collaborative 3D model capabilities to design the complex piping system and pool structure. After completing the design, Navigator conducted clash detection, ensuring a streamlined construction process that eliminated rework. The project team also combined BIM technologies with coding techniques, creating a component library that was referenced in all stages of the plant’s lifecycle.

Outcome
Bentley’s design applications, including OpenPlant and OpenBuildings Designer, contributed to boosting design efficiency by approximately 20 percent and reduced design time by one month. Once the design was completed, MCC used Navigator for model checking and clash detection and LumenRT for cruise simulation. Navigator identified 200 errors, omissions, and collisions. MCC had a zero-collision construction experience by using Navigator in advance. This saved about 7 percent of construction time and 2 percent in project costs due to avoided design and on-site rework. In construction, MCC had no design problems compared to similar projects. As a result, MCC shortened the construction timeline by 40 days. Moreover, Bentley software diminished material use by 8 percent. The Jinqiang Shouan Water Plant has solved the water use problem in the Wenjiang District of Chengdu and has supported the city’s growing development, improved quality of life, and solved water supply shortages in the area.

Software
With such a complicated structure, drawings were difficult to understand, but a 3D model made it simpler for the multidiscipline design team to see all aspects of the plant. For the design process, MCC used OpenBuildings Designer for architecture; OpenPlant Modeler for the pipelines; ProStructures for the steel structure; AutoPIPE for the system diagram; Bentley Raceway and Cable Management for cable laying; Bentley Substation for electric; MicroStation for equipment; Power GEOPAK for terrain; and OpenRoads Designer for road design. Integrating this software within a connected data environment on ProjectWise certified the uniformity and standardization of the 3D model. Navigator’s visualization capabilities were used for design review, and Bentley’s project and asset management applications streamlined workflow processes in design and construction and are continually referenced in the operations and maintenance stages.
