BIM implementation in a New Zealand consultingquantity surveying practice

5D BIM generating cost data via the building information modelling (BIM) process has the potential to be used by quantity surveyors (QSs) to streamline their workflows and increase their provision of a quality service. Consultant QSs experienced in the use of 5D BIM, from the New Zealand office of a large global practice, were interviewed on their perceptions of the benefits of, and barriers to, 5D BIM implementation within their firm. Findings suggest that 5D BIM has numerous benefits over traditional methods, chiefly through the increased efficiency and visualisation that BIM provides, along with the rapid identification of design changes. However, realisation of these perceived benefits is limited to date, due to several barriers hindering 5D BIM implementation: incomplete design and insufficient model object data in the BIM model; a lack of standards to facilitate electronic measurement; legal issues, and a lack of government support. Increasing 5D BIM implementation, in tandem with increasing use of collaborative project working through integrated project delivery, will, however, facilitate these benefits being achieved to a far greater extent in the future. Further research is recommended to identify the BIM skills which QSs will need in the future to reach the full potential of 5D BIM.
