Abstract: Various examples are provided related to virtual performance compatibility checking and management for modular construction. In one example, a method includes segmenting boundaries of as-built and as-planned models of a construction element; determining features of each boundary segment of the as-built and as-planned models; determining similarity ratios for matching pairs of boundary segments of the as-built and as-planned models; comparing a total similarity ratio based upon the similarity ratios for matching pairs of boundary segments with a specified threshold; and snapping the as-built model in position in a point cloud in response to the comparison. A system comprising computing or processing circuitry can execute a program or application to implement the similarity/compatibility checking methodology. The similarity/compatibility checking methodology can be implemented within a construction performance modeling and simulation (CPMS) framework.
