1. A system for determining serviceability and remaining life of an in-service structure comprising:
a processor circuit; and
a memory coupled to the processor circuit, the memory comprising machine-readable instructions that, when executed by the processor circuit:
access three-dimensional (3D) scan data captured by a scanning device representative of an in-service structure;
based on the 3D scan data, generate in-service computer-aided design (CAD) data representative of an in-service volume comprising an in-service surface corresponding to the in-service structure;
access nominal CAD data representative of a nominal volume comprising a nominal surface, wherein the nominal volume corresponds to a nominal structure, and wherein a portion of the nominal surface corresponds to the in-service surface; and
replace the portion of the nominal surface with the in-service surface to generate modified nominal CAD data representative of a modified nominal volume comprising the in-service surface;
compare the modified nominal volume of the modified nominal CAD data to the in-service volume generated from the 3D scan data;
determine, based on the comparison, whether the modified nominal volume of the modified nominal CAD data corresponds to the in-service volume of the in-service structure within a predetermined tolerance;
in response to determining that the modified nominal volume corresponds to the in-service volume within the predetermined tolerance, determine at least one of a serviceability level or remaining life estimate of the in-service structure based on the modified nominal CAD data; and
display an indication of the at least one of the serviceability level or remaining life estimate of the in-service structure.
