Digital Twins

A digital twin is a digital counterpart of a physical object kept current with live data, so that the state of the building and its digital representation do not drift apart. The field studies how geometry, asset data, sensor data and models are brought together, and which decisions genuinely improve as a result. It differs from BIM in that a twin follows use, not construction.

FM is the only function that experiences the building in use, and therefore the only one that can keep a twin current. At the same time FM is usually not the client for the model: it inherits a handover model that is out of date within a year. ISO/TR 41016:2024 places this technology within the wider overview of FM technology and treats it as one option in a portfolio, not an end state. That framing helps FM invert the investment question: which decision improves, and is a twin the cheapest route to it?

• Which decision demonstrably improves with a current model, and how often is that decision taken?
• Which data layer must genuinely be live, and which may remain static?
• Who owns the model after handover, and who pays to keep it current?
• How is divergence between model and reality detected rather than assumed?
• Which personal data arises unintentionally from linked usage data?

• Put the information requirement in the construction or refurbishment contract; the operational phase is too late.
• Budget upkeep as a structural operating cost, not as a project cost.
• A twin changes the verification relationship with providers: the client can see for itself what happens, provided the data belongs to the client.
• Sensor data about use nearly always touches privacy; treat that as a design question, not an afterthought.

• Demand organisation

  Only a client with its own information position can use a twin as a verification instrument.

  When the provider manages the model, information power shifts with the contract.

• ISO 19650-3 — information management in the operational phase.

The standards section arrives in Part 7.

• A handover BIM model presented as a digital twin, while there is no live data link.
• A 3D visualisation sold as a decision instrument without underlying asset data.
• Savings claims from vendor material based on a single pilot building and used as a portfolio figure.

Independent evidence of operational benefit remains scarce: many published cases come from vendors or subsidised pilots, and rarely with a credible baseline. Open research questions are the cost of staying current across a building life, interoperability between BMS, CAFM and model environment, and whether predictive use of twins holds up outside new-build with full sensor infrastructure.
