title Development of schematic estimation system through linking QTO with Cost DB
source Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 507-516
summary Cost estimate in architectural projects is an important factor for decision-making and financing the project in both early design phase and detailed design phase. In Korea, estimate work based on 2D drawing has generated problems of difference form QTO according to worker’s mistake and know-how. In addition, 2D-based estimation are obtained uncertainty factors of estimation depending on lack of infor- mation due to becoming larger and more complex than any other pro- ject of the architectural project. In order to solve limitations, this study is to suggest an open BIM-based schematic estimation process and a prototype system within the building frame through linking QTO and cost information. This study consists of the following steps: 1) Ana- lysing Level of Detail (LoD) to apply to the process and system, 2) BIM modelling for open BIM-based QTO, 3) Verifying the quality of the BIM model, 4) Developing a schematic estimation prototype sys- tem. This study is expected to improve work efficiency as well as reli- ability of construction cost.
