SFG20 without a spatial twin is faith-based maintenance
Hard FM teams complete SFG20 schedules every day, but the audit trail is mostly trust. A photoreal twin turns each PPM visit into evidence.

SFG20 is the gold-standard maintenance specification for hard facilities management in the UK. Tens of thousands of buildings run their PPM schedules to it. The schedules are clear, the asset categories are defined, the frequencies are agreed. So far, so good.
The honesty problem starts at the next layer down. When a planner allocates a quarterly inspection of, say, a fire damper, an engineer attends, opens a CAFM ticket, and closes it as complete. That is the evidence trail: a ticket and a tick.
FM directors know this. They also know that on a busy multi-tenant portfolio, the gap between "ticket closed" and "asset actually verified in place, in working order, in the right location" is real. The reputational and regulatory risk lives in that gap. The Building Safety Act 2022 golden thread, ISO 41001 and any insurer condition that follows a loss all want more than a ticket.
A photoreal 3D twin of the building gives every engineer a known canvas. Each asset has a fixed location, a fixed identifier, a recorded condition and a recorded last-seen image. When a damper inspection is scheduled, the engineer is routed to the exact ceiling tile, with a reference image of how it looked last time. The closing step is a capture — a five-second mobile snap or scan — that updates the node in the twin.
The CAFM ticket is still closed. But now it is closed against an artefact, not a checkbox. Three things shift:
The static twin is useful on day one. The bigger prize comes when live IoT — building management system, sub-metering, air quality, occupancy, leak detectors, door contacts — is overlaid onto the same coordinate frame. The damper now has its airflow trend. The fire door has its open-time history. The plant room has its acoustic baseline. Anomalies surface where they actually are, geometrically, instead of as a row in a BMS export.
For client-side FM directors managing TFM contracts across portfolios this is a step change in oversight. For service-side directors at the major hard FMs — the Equans, Mities, ISSes, CBREs and Sodexos — it is a route to higher-margin, evidence-led service tiers without adding headcount.
The same spatial twin that satisfies an SFG20 PPM run also feeds the Building Safety Act golden thread for higher-risk buildings, the L8 water hygiene log, the asbestos register location, the CDM 2015 site information at refurb start, and the insurer's pre-renewal survey. One capture, multiple obligations served.
Most FM tech debates focus on which CAFM, which BMS, which IWMS. The data layer underneath is the part that is missing, and the part that determines whether the compliance evidence is real.
In our pilots, the fastest wins come from three categories: fire safety assets (compartmentation, damper, AOV, signage), water hygiene assets (TMVs, calorifiers, dead-leg risers), and back-of-house plant. All three are statutory, all three are inspected on schedules, and all three have known evidence weaknesses in classical CAFM.
If your FM portfolio is being asked harder questions by the BSR, your insurer or your board, the next step is not another CAFM module. It is a baseline scan of one of your highest-risk buildings.
