Abstract

Estimating the cost of a building is a very important step in the process of a construction project. The results of the cost estimates are used as important information in the overall aspect of the construction project. Because of this, accurate cost estimates are very important. However, existing cost estimates basically include the possibility of human error. In addition, there is a problem that the accuracy of the cost estimation varies greatly depending on the expertise of the estimation expert. And the accuracy of the calculation of the quantity due to errors in the design book for the calculation of the quantity is reduced. BIM is a solution to solve the problem of existing estimates. BIM-based cost estimates can be calculated automatically using the property information of the BIM model, thus ensuring the accuracy and reliability of the project cost prediction. The purpose of this study is to verify the accuracy of the BIM-based detailed cost estimation. For this purpose, this study derived a detailed cost item that can be computed on a BIM. In addition, the effects of BIM-based detailed cost estimation were analyzed through actual case project. As a result of comparative analysis of the cost estimates of the demonstration complexes, the difference between the existing estimates and the BIM detailed estimates was 99.5%.
