Development of a conceptual model for evaluating the success of BIM-based construction projects

PurposeResearch into project success (PS) has a long pedigree as has research into the impact of building information modelling (BIM) on projects. Yet, despite the many revealed advantages BIM is known to deliver to projects, the relationship between the level of BIM application within a project, BIM's ability to impact a project at that level and the consequent effectiveness and range of success factors BIM is able to bestow across levels remains unmapped. Given the importance of evaluating the success of BIM-based construction projects (BBCPs) and the necessity to ensure the continual improvement of the BIM process, there is a need to identify the relationship between the level of BIM employed on a project and the specific PS factors that BIM is able to impact at that level.Design/methodology/approachThis study puts forward a conceptual model for evaluating the success of BBCPs. A thematic synthesis approach is taken, using Scopus and other databases, and retrieving relevant articles from some 50 journals.FindingsEight success criteria for BBCPs were extracted and categorised according to BIM's ability to impact them across four levels of project application. Mapping BIM's variable impact at these four levels against the eight success factors produces a model for evaluating the PS of BBCPs. The model posits that the success of a BBCP is a function of the extent to which BIM is applied to the project. Moreover, the findings indicate that an increase in the number of PS criteria (PSC) for a BBCP is a derivative of BIM effectiveness, and not BIM impact.Originality/valueThis work constitutes seminal research to examine the concept of PS and PSC for BBCPs with the view to developing a model for evaluating the PS of BBCPs.
