Abstract
In one embodiment, a modeling process adds unique numbers for field welds or flange bolt-up connections to a virtual construction model of an infrastructure construction project. Based on the virtual construction model and a fabrication data file that describes a portion of the infrastructure construction project, a QC drawing generation process generates a QC drawing for the portion of the infrastructure construction project that includes balloons linked to locations of field welds or flange bolt-up connections, each balloon including the unique number of a corresponding field weld or flange bolt-up connection. A copy of the QC drawing is provided to a field inspection worker. Subsequently, a marked-up copy of the QC drawing is received back that includes field inspection results associated with the unique number of each field weld or flange bolt-up connection. The marked-up copy may be maintained in a document control system.
