Building Information Modeling (BIM) of recent years has become a buzz word often believed to be new technology but in fact BIM has been in development since the late 70s, technologies such as Revit and ArchiCad began in the 80s, 30 years ago. Even with its history, the concept and use of BIM is only now reaching a tipping point in the Canadian construction industry, from National BIM Standards International BIM Report 2017, 78% of Canadians surveyed believed BIM is the future of project information with already 67% of respondents currently using BIM.
Building Information Modeling is the process of collaboratively developing and managing an integrated digital model containing a built asset's geometry and lifecycle information. The model acts as a 'single-source of truth' and supports the many practices that are involved in the design, construction, operation, and managerment of a built asset. The underlying principle of BIM is the data driven approach to project delivery as opposed to the traditional, 2D/representational approach that has been the norm. While a single, unified model is still some ways off due to a number of practical, technical, and organizational issues, there is increasing empirical evidence that BIM, deployed within an appropriate environment, can lead to important gains in efficiencies. These gains are attributable to the high quality and streamlined information flows that result in fewer errors and support global optimization of asset lifecycle practices.
