Recovering contractor billing at Shanagan

Contractor billing is one of the quietest sources of loss on a large site. Invoices arrive for hours worked and loads moved, but without an independent record there is no way to check them against what actually happened.
At Shanagan, we cross-referenced three data sources the operation already had: gate access logs, fleet telemetry, and vision detections at the loading face. Each on its own was incomplete. Together, they reconstructed an objective timeline of activity.
Reconciling that timeline against contractor invoices surfaced over-billed hours and trips that simply hadn't occurred. The recovery paid for the deployment well inside a single quarter, and the ongoing deterrent effect compounds every month.
The lesson generalizes: the data to catch this is usually already being collected. What's missing is a model that fuses it into one record everyone can trust.
