Building Regulations Notes Agent
A policy-governed AI agent that references Approved Documents A to T to produce annotated Building Regulations notes from within Revit. Cost-tiered model routing and prompt caching keep it fast and economical on high-volume queries.
Building Regulations queries arrive constantly on live projects. The question is always the same: does this design decision comply, and where is that set out? Looking it up manually is reliable but slow. This agent makes it fast without removing the human judgement.
The agent is mounted inside Revit via MCP and has direct access to Approved Documents A to T. When a query arrives, it selects the relevant document, locates the applicable clause, and returns an annotated note that can be attached to the model or the drawing register.
A confidentiality gate flags any query that touches fire, structural or CDM risk for human review before the note is used. The agent gives an answer; a named person decides whether to rely on it.
Cost-tiered model routing means routine queries use a lighter model and only complex multi-document questions route to the full reasoning model. Prompt caching reduces token overhead on repeated queries against the same document.
