The building knowledge lives in one person's head.
Most estates depend on a small number of people who know where the isolation valves are, which riser feeds which floor, and what is actually behind the door marked Store 3. Drawings are out of date, O&M manuals are PDFs nobody reads, and asset registers are spreadsheets with no spatial context.
When that person leaves, retires, or is on another site, the knowledge goes with them — and every contractor visit starts with someone walking the building to explain it.
How FM teams use the twin
Contractor briefing before arrival
Send the link with the work order. The contractor sees access routes, plant position, clearances and hazards before they price or attend.
Asset data in position
Tag plant with make, model, serial, install date, service history and a link to the manual — attached to the physical location, not a row in a spreadsheet.
Remote triage
Helpdesk staff can see the reported area immediately, judge whether it is a genuine call-out, and send the right trade first time.
Emergency and safety information
Mark isolation points, stopcocks, valves, panels, fire equipment and escape routes so they can be found under pressure.
Mobilisation and handover
When a contract changes hands, the incoming provider inherits a documented estate instead of a walkaround and a box of files.
Measurements on demand
Take dimensions from the twin for replacement plant, access routes and equipment delivery without another site visit.
A twin does not replace your CAFM system. It gives it something the spreadsheet never had — a place.
Tags in the twin can link straight out to the asset record, work order or document you already hold elsewhere, so the twin becomes the way people navigate to your existing systems rather than another system to maintain.
The roof is usually the least inspected part of an estate and the most expensive to get wrong. We inspect it by drone — no access equipment, no working at height — as a standalone job or alongside the interior capture. See drone roof inspections.
Document the estate once, properly.
Tell us how many buildings and roughly what area, and we will scope a phased capture programme.
