A Golden Thread Record That Builds Itself

The Building Safety Act requires a continuous, accurate digital record of information about a higher-risk building, from design through construction and into occupation, so the right people can access the right information at the right time. It's a record-keeping and traceability requirement, not a single document.

Higher-risk buildings under the Act, generally residential buildings at least 18 metres or 7 storeys tall. Mirage builds the golden thread record from whatever documents your project already produces, regardless of which specific threshold applies to you.

No. Those are named legal roles under the Act with responsibilities Mirage doesn't take on. What Mirage does is build and maintain the underlying record those roles depend on, so the information is complete and traceable when it's needed, rather than being a manual assembly job under deadline.

Every document, decision, and change already indexed is retrievable with its full history, so assembling the golden thread evidence for a Gateway submission or a Building Safety Regulator request pulls from a maintained record instead of being rebuilt from scratch each time.

Yes. Missing approvals, undocumented design changes, and information that doesn't reconcile between design and as-built records are surfaced as they occur, not discovered during a review.

Yes. It connects to the document management, BIM, and common data environment tools already in place on the project. No new system for design and site teams to learn.

This would be Mirage's first UK golden-thread deployment, delivered remotely against your existing document management and BIM tools, the same delivery model already running with clients in France, Spain, Morocco, and the US. No site presence is required to build or maintain the record.

4 to 6 weeks to a production deployment: indexing your existing project documentation first, then a parallel pilot on one active project before full rollout.

Pricing starts with a fixed-price pilot on one active project, so you see the golden thread record built from your own documents before committing to anything larger. After that, it moves to an annual subscription priced by volume, quoted in your first conversation with us.
