Abstract

Designing modern water supply systems is a complex process involving precise flow rate determination, pipe sizing, and head loss analysis. Currently, these tasks remain largely manual; existing tools lack full automation, leading to higher costs and technical errors. This study develops an integrated BIM-based solution that fully automates hydraulic calculations and simultaneously updates the building information model, thereby increasing design efficiency and enhancing documentation quality. By leveraging Dynamo-based automation to overcome the limitations of Revit’s native 'Pipe Sizing' and enforce compliance with Vietnamese standards (specifically TCVN 4513:1988), the tool significantly streamlines the hydraulic design process. Beyond basic sizing, it automatically identifies the most hydraulically adverse pipe run to accurately determine critical system pressure. This comprehensive workflow reduces manual iteration and ensures calculation accuracy and model consistency throughout the project lifecycle.
