Digital twins are most reliable when the virtual model mirrors the actual asset in real time. The key problem is when the current as-built data isn’t kept up to date. If field changes, deviations during construction, or unexpected conditions aren’t recorded promptly, the twin drifts from reality. That mismatch can lead to incorrect maintenance, planning errors, safety risks, and poor decision-making because actions are based on outdated information rather than what’s physically present. Keeping as-built data current requires strong processes for capturing changes, updating drawings and the model, and feeding accurate field or sensor data into the system. Updating BIM with as-built data and responding to design changes are part of good practice, while real-time data can be imperfect in practice; the core issue here is the lag in updating as-built information.
