Will Building Information Modeling (BIM) transform cost estimating in Australia?

Purpose of this paper. The aim of this research is to investigate the use of Building Information Modeling (BIM) as an aid to improve cost estimating practices on construction projects in Australia. The research assesses the extent to which BIM is being used as an aid to cost estimating in Australia and also other regions around the world, its ability to improve cost estimating practices and whether its use will become more prominent for cost estimating in the future, and associated reasons. Design/methodology/approach. A hybrid research methodology was adopted, including an online questionnaire survey and in-depth interviews with both of senior construction industry professionals in Australia. Findings and value. Findings indicated the use of BIM allows cost estimating to be improved by making cost estimates faster to produce as well as making them able to be produced earlier in the design process, which combined, allows for more influential and effective decision making, reducing the probability of the need for re-design and the associated time and cost overruns of doing this. Originality/value of paper. This study provides a useful reference to industry practitioners about how BIM can assist cost estimating in construction projects. Conclusions. BIM's abilities for cost estimating, therefore, can increase a project's likelihood of success and increase the value of cost estimating to a project.
