According to an example, three-dimensional (3D) scan data representative of an in-service structure that is captured by a scanning device is accessed by a processor circuit. Based on the 3D scan data, in-service computer-aided design (CAD) data representative of an in-service surface corresponding to the in-service structure is generated by the processor circuit. Based on the in-service CAD data representative of the in-service surface, at least one of a serviceability level or remaining life estimate of the in-service structure is determined. |
