A method and system provide for reducing gaps between two mating parts. Either or both parts may be nondestructively inspected at a plurality of locations on a surface to gather a data set relating to the part thickness. The data set may be used to calculate a set of as-built thickness values for the part and a set of deviations from a design model. A mating area may be determined for mating surfaces of the parts. One or more layers of sacrificial material in the mating area may be prepared for any deviations greater than a design allowance. The system may include a ply cutting device and an additive manufacturing device coupled to a computer to receive the sacrificial material layer data and shim data and to cut the one or more layers of sacrificial material and to construct the shim. A shim may be constructed for any deviations equal to or greater than a minimum shim thickness. The one or more layers of sacrificial material may be applied to the part, cured, and machined to a desired thickness. The shim may be applied between the part surfaces. The parts may be fitted and assembled together.
