The project benefits of Building Information Modelling (BIM)

Theoretical developments in Building Information Modelling (BIM) suggest that not only is it useful for geometric modelling of a building's performance but also that it can assist in the management of construction projects. The purpose of this paper is to explore the extent to which the use of BIM has resulted in reported benefits on a cross-section of construction projects. This exploration is done by collecting secondary data from 35 construction projects that utilised BIM. A set of project success criteria were generated and content analysis was used to establish the extent to which each individual project met a criterion. The most frequently reported benefit related to the cost reduction and control through the project life cycle. Significant time savings were also reported. Negative benefits were mainly focused on the use of BIM software. Cost/benefit analysis, awareness raising and education and training are important activities to address the challenges of BIM usage.

► We explore the project benefits of Building Information Modelling (BIM).
► We analyse 35 construction projects which report on the use of BIM.
► Cost reduction and control are the most commonly reported benefit.
► Time savings and enhanced communication are significant positive outcomes.
► Challenges from using BIM-related software produce negative benefits in some cases.
