Implementation of Building Information Model (BIM) in terms of quantity takeoff (QTO) and estimation at construction consultant company in Vietnam

Abstract

This research focuses on the implementation of BIM on quantity takeoff (QTO) and estimation process in construction consultant companies in Vietnam from the perspectives of investigating BIM as a new method and the application of BIM to the Vietnamese working condition. A literature review was analyzed in order to understand and investigate the research problem and an online survey was distributed in order to find out the main inhibiting reasons for the adoption of BIM in Vietnamese construction consultant company. Overall, the lack of demand in the construction market is the main obstacle, followed by the high initial investment and the concern of risk in investing in the new technology. Besides, the conception of inability to integrate the Vietnamese Standard Construction Codes with BIM tools, the difficulty in approving estimation and a gap in understanding of BIM workflow are also the main limitations. Besides, some mitigation measures to overcome these limitations and barriers are also developed based on the analysis and synthesis of the literature review. In addition, BIM application is initially used in the design, however, it is not considered widely as the method for QTO and estimation process in construction consultant company.
