Construction cost estimation in the early phase provides the opportunity to make reasonable decisions related to the project. For estimating this cost, various methods have been developed. But several problems have been recognized like accuracy, relation beteewn design and cost etc. In this study, we developed the method of cost estimating for building parts. The modified method has defferent ratio of space functions to calculate cost more correctly. Also historical cost data is used in this modified method for architects to estimate cost conveniently. By this modified method, we expects architects should easily design buildings based on cost.

There are various standards and manuals on the quantity takeoff for construction estimation. However, a lot of time and money has been spent on retraining because of difference between practice and education. Therefore, the main purpose of this paper is to suggest improvement to analyze problems and limitations of the existing educational content for quantity takeoff. In order to achieve research objective, comparative analysis for quantity takeoff contents is carried out. This study will be extended to assist in effective quantity takeoff in building projects by supplementing the existing issues with quantity takeoff contents and developing a BIM-based quantity takeoff multimedia contents that use diverse media to increase the understanding on the subject for a non-professional.
