BIM-compliant recording of construction progress. The KorFin® BM app is used to create performance reports for a KorFin® project. This means that all specialist objects are reported as “built” or a performance range of a constructed earth or superstructure volume is fixed. The identified services are then imported into KorFin® and can be further evaluated. This means that the current status of the construction site can be modeled at the push of a button.
