  Abstract

Although BIM-based QTO and estimates have various advantages, they are not actively applied due to the absence of standard data models and the attribute requirements. In order to establish BIM-based QTO and estimates, criteria for input attributes and data format are required for quantities produced by BIM software to be delivered to the estimation software without loss. This research suggests standardization for the BIM-based data distribution system in terms of data composition criteria and data format. For the purposes, the study was carried out as follows. 1) Previous research using IFC Qset and case studies on BIM-based QTO and estimate were analyzed. 2) BIM-based design, QTO and estimation processes and the exchange requirements for road projects are defined applying the IFC development Methodology. 3) Pset and Qset were developed according to IFC Pset extension methodology. 4) I/O testing of exchange information in BIM software was performed to verify the process of extraction of quantities from models. In the future, it is planning to verify research including quantitative measurement of application effects. In stages of research, the results of this research intend to be a basis of BIM-based QTO and estimate guidelines for road domain and contribute to ensuring accuracy and reliability of the estimation work by reducing manual work and increasing BIM-based automatic work linked to estimation software.
