INVESTIGATION OF PRACTITIONERS’ PERCEPTIONS FOR DEVELOPING BUILDING INFORMATION MODELLING (BIM) - BASED VALUE ANALYSIS MODEL

As the architecture, engineering and construction (the AEC) industry is expanding the size, and more complex in recent years, there are various approaches to enhance efficiency and effectiveness in the AEC industry. Building Information Modelling (BIM) is regarded as one of responses to such a change in the market. While the application of BIM might focus on the enhancement of efficiency and collaboration of all the stakeholders during construction projects, value engineering (VE) has been prevalent to maximise the value of the projects and customers' satisfaction. The South Korean Government has established the regulations to adopt VE as a means of amelioration of the nature of the AEC industry. Although BIM and VE would have a significant impact on the cost optimisation and performance enhancement for construction projects, it is scant that the research in terms of combining BIM and VE for more synergic effect towards the AEC industry. This research was a part of a three years research project to develop an add-on of BIM software which would make it possible to evaluate of individual objects' value. The aim of this research was to confirm the users' perceptions towards BIM and VE as well as to corroborate their usefulness by practitioners from construction firms and design companies in South Korea. In this study, approximately 87% of the research participants has already recognised BIM and its practicability in the AEC industry. Additionally, the respondents were asked their perceptions towards the usefulness of BIM-based VE analysis software. Majority of the survey participants, which accounted for 67.35%, replied that the intended add-on software for BIM would be applicable to analyse the value of their projects. With the users' requirements, the research participants answered the basic unit of VE analysis in conjunction with BIM software. The respondents indicated that components would be the basic unit for assessing and analysing the value of a building. This result was in accordance with our intention to develop BIM-based VE analysis software.
