Project Summary

    • Beijing Institute of Water – Beijing South-to-North Water Diversion Auxiliary Project- Hexi Branch Project
The Hexi Branch project is part of the Beijing South-to-North Water Diversion initiative to optimize the allocation of water resources in northern China. Completion of this project will improve regional water supply conditions and serve a population of 390,000. The project included three pumping stations, water transmission lines, and five water outlets. Beijing Institute of Water was responsible for drawing designs and initiated a collaborative 3D design strategy.

This project required large-scale terrain modeling and analysis and simulation of pumping station operations. Beijing Institute of Water’s 3D design process was founded on ProjectWise to enable simple collaboration. To meet the parametric design requirements, the project team turned sections of the model drawings into detailed construction models with MicroStation. In addition, the team created a complex pipeline mesh model with MicroStation and calculated the shortest distance from the mesh surface of the pipelines to the water conveyance tunnels by constructing geometric algorithms. This optimized the design proposal modifying and protecting relevant pipelines.

Three-dimensional geological models of the network site were conducted, saving about 60% of the time used with traditional 2D processes. Comparing completed building point cloud models with the design phase models eliminated the use of large amounts of paper, saving time and money. Furthermore, using MicroStation for calculations saved 80% in time over the previously used 2D method.

The team used ProjectWise as the collaborative platform, streamlining workflows and improving efficiency. Surface digital elevation and building models were created from collected point cloud data using Descartes to accelerate design planning through accurate visual displays, and 3D parametric modeling was conducted in MicroStation. The organization utilized HAMMER to analyze and calculate the hydraulic transition processes of the pumping station’s operating conditions. The team examined and designed underground structures and building foundations with STAAD, analyzing displacements under complex load conditions, which offered a baseline for structural reinforcement designs.
