Natural Language BIM
AI systems that allow users to query and interact with BIM models using natural language.
Definition
Natural Language BIM uses large language models and AI to enable users to ask questions about BIM models in plain English. Instead of navigating complex software interfaces, users can simply ask what they want to know and receive instant answers. These systems can query model data, generate reports, find elements, and even modify models based on natural language instructions, making BIM more accessible to all project stakeholders.
In Depth
Natural Language BIM allows users to query BIM models using everyday language instead of complex Revit filters or schedules. Instead of navigating through Revit's schedule creation workflow to find all exterior walls with a fire rating of 2 hours, a user can ask "show me all 2-hour rated exterior walls" and get the result immediately.
The value is in accessibility. BIM models contain enormous amounts of structured data, but accessing that data typically requires advanced Revit skills. Project managers, specifications writers, and field engineers — people who need information from the model regularly — often cannot extract it themselves. Natural Language BIM gives every team member direct access to model data through simple questions.
This also enables cross-discipline queries that are difficult to run manually. "Which rooms on the second floor have both sprinkler coverage and a fire alarm pull station within 75 feet of an exit?" involves querying architectural, fire protection, and fire alarm models simultaneously. Natural Language BIM handles the query logic and returns the answer, saving the coordination time that would otherwise require meetings between three different discipline leads.
Examples
Asking 'How many doors are on the second floor?' and getting an instant answer
Requesting 'Show me all the HVAC equipment in mechanical room 201'
Querying 'What is the total area of all conference rooms?'
