COMP³ runs on a structured regulatory model. The model holds four kinds of object: duties, the triggers that decide when a duty applies to a project, the actions a duty requires, and the evidence that proves the action was taken.
Each object is mapped to its primary statutory source. Those sources are the Building Regulations 2010 (as amended), the Building Safety Act 2022, and CDM 2015, together with the standards those instruments reference. A duty exists in the model because a source puts it there, and each mapping is recorded.
Every duty carries its own verification log. Verified has a narrow meaning here: the duty has been checked against the primary source on legislation.gov.uk or gov.uk. Secondary commentary, guidance summaries, and trade explainers are useful for orientation, and we do not treat them as sources.
Verification status is visible in the product on every duty, so you can see the state of a duty at the point you are relying on it. Where a duty has not been verified, the product says so.
Independent review by a chartered subject matter expert is a release condition for production. No production version ships without it.
That review has not yet gated a production release, because there is no production release. COMP³ is in validation with founding users. Sessions use realistic mock data scenarios, and no live project data is required. We would sooner state the gate plainly than imply a review that has not happened.
COMP³ does not replace professional judgement, legal advice, specialist design review, or Building Control and BSR approval. It gives you a structured starting point and a record of how you got there. The duty to discharge the BRPD role remains yours.
If the model gets something wrong on your project, we want to hear it. Tell us at info@comp3.co.uk.
