PBS기반의 QDB를 통한 수량산출 및 내역정보 개선 방안 연구

Abstract

In construction project, the cost estimation process is consisted as follows: drawings production, quantity tate-off, and cost estimation. As a result of cost estimation, the BOQ and BOM documents are produced. However these documents have no relationship with the quantity take-off records, and it is difficult to check the accuracy or history of the cost and the quantity data. With this problem, quantity take-off process are repeated everytime when it is required until project is finished in most of the domestic construction projects. If it is possible to track the quantities of BOQ and BOM items, this repeated processes could not be required. In this study, we suggested the PBS based Quantity Database(QDB) method for the efficiency of quantity take-off and BOQ Information. The Product based Breakdown Structure(PBS) could be adopted on the quantity take off and BOQ information in order to track the related data, and this would be useful for check the accuracy of the quantities and costs calculated before. Also this method could provide the various analysis methods for quantities and cost data during the construction project.
