Abstract
The purpose of architectural competition is to choose the best design to satisfied with the goal of a project. If the matters which are not satisfied with the owner's requirement can't be found out in the evaluation phase, however, a good sum may have to be paid for design change. Additionally, as time goes on, the possibilities for modification of the original design will be decreased. For this reason, it can be critical to shorten the design errors with the accurate work in the early part of design phase for success of a project. On this, BIM using extensively since the late 2000's could be a good alternative. BIM(Building Information Modeling) can minimize design errors through managing data with 3D-based information. Actually, domestic public institutions recognize the advantages of BIM, and are increasing ordering quantity BIM-based project. However, some of the BIM-based projects which were already performed with great expectations have showed some problems. With this background, it is needed to find out the effectiveness for reducing design errors with applying BIM process to the project. Thus, in this study, it will be found out that in what parts of the architectural competition, the effectiveness of BIM process shows up. And, it will be found out that in what parts of the architectural competition, the problems shows up through comparing 2D-based design process and BIM-based design process.
