The present invention generally relates to the process of analyzing all systems and sub systems in the construction of a building to identify conflicts or design errors, and correcting the errors at the design stage so the construction can be completed with minimal or no issues. Through the analysis of the framing, walls, windows, HVAC, plumbing, electrical and other systems or sub systems that are typical in the construction of a building, the framing can be designed to anticipate the HVAC and plumbing, and the frame members can be built with the cutouts or contours to accommodate these systems. The present Invention uses the unique feature of conflict check in which the members or elements which has conflict are identified and a list of all conflict members is prepared. The List also shows the condition under which the given conflict occurs.
