CONSTRUCTION COST MANAGEMENT SYSTEM AND CONSTRUCTION COST MANAGEMENT METHOD

摘要

To suitably set allocation of a consumption tax difference when consumption tax alteration occurs in the middle of construction over multiple years.SOLUTION: A construction cost management system 100 calculates a consumption tax difference on the basis of alternation information and a design amount allocated each year, and outputs a worksheet including the consumption tax difference and areas for inputting values to allocate the consumption tax difference amount to each year. The construction cost management system 100 determines whether or not the values inputted in the input areas and values inputted based on the consumption tax difference amount are appropriate. If it is not appropriate, the construction cost management system outputs an error message, and if it is appropriate, reflects the inputted values on a construction design document.SELECTED DRAWING: Figure 1
