Abstract: Provided is a progress rate roll-up system for calculating a Level 3 progress rate based on a Level 4 progress rate. The progress rate roll-up system includes a Level association unit, a mapping association unit, and a Level 3 association unit. The progress rate roll-up system further includes at least one of a BEME database (DB), an EWS DB, an EIPS DB, a mapping DB, a EIPS_No_Group_MH DB, a CPVAL DB, and a EIPS_No_MH DB. Accordingly, because not only the Level 4 progress rate but also the Level 3 progress rate may be calculated, more accurate analysis data may be provided to complete a project within an allocated budget and a given construction period.
