Automating ISO 7817 Compliance: A Practical Workflow Using Dynamo, Revit, and LLMs

Producing and controlling data from project models at a defined level is still largely a manual and error-prone process. This session will present ISO 7817 (Level of Information Need), the emerging standard beyond traditional Levels of Detail, and show how BIM execution plan requirements link to a Revit model. The session will explore a closed-loop workflow that tracks data from requirements to reporting. The method includes transferring information requirements from Microsoft Excel into Revit elements as parameters using Dynamo, guiding modelers by showing what data to input and why within element properties, collecting data back into Excel, and automatically generating performance reports by doing a row-by-row comparison of “Required” and “Provided” data using a large language model (LLM).
