Abstract

Construction projects are known for frequent cost overruns, due to different issues including the limitations of conventional cost management approaches. Building Information Modeling (BIM)supported cost management (5D BIM) consists in associating the cost variable with a BIM model in order to optimize the management of construction costs. Although several studies have been conducted in different countries to identify the benefits of, and barriers to, the implementation of 5D BIM, data on its implementation and associated practices in Quebec are missing. The objective of this study is therefore to present the general picture of the implementation of 5D BIM in the Quebec’s construction industry. In order to achieve this objective, an in-depth literature review was conducted, and a questionnaire was developed and distributed to a sample of cost management specialists in the AEC industry in Quebec. The results suggest that that while 5D BIM is recognized to foster the production of better estimates, the automation of estimation is still far from being a reality. Excel is still the main tool for allocating costs to quantities extracted from BIM models and for estimates preparation. Thus, 5D BIM is mainly used for cost estimating, budgeting and cost control but much less for claims management.
