Computer Script Development in Dynamo-Revit Software for Building Foundation Design

Building Information Modeling (BIM) technology has transformed the construction industry, offering efficient data management and design processes. This study focuses on applying BIM to foundation design by developing a scripted prototype in Dynamo and Autodesk Revit to calculate the size of shallow foundations. The research integrates Revit for modeling and Dynamo for weight calculation, with the total weight exported to Microsoft Excel for foundation design based on Terzaghi’s bearing capacity theory. A closed-form cubic equation rapidly and accurately determined the foundation size. Unlike traditional hand calculations, the developed script offers faster and more precise results. The study highlights the potential of BIM tools to streamline foundation design processes, with the example case of a square-shaped foundation under vertical load in Chiang Mai, Thailand. Future research could explore the application of this method across various soil types and more complex building models.
