Abstract
Building Information Modelling (BIM) has not been sufficiently proliferated in the developing construction communities. This is owing to the lack of incorporating the key success factors (KSFs) of BIM implementation in a phase-based roadmap to support implementing BIM in practice on a step-by-step approach. With this in mind, this work aims at (1) defining the KSFs for implementing BIM within the developing economies' socio-economic environment, (2) investigating the interrelationships among the KSFs, and (3) establishing the KSFs in a phased approach to devise a roadmap for their implementation on a step-by-step basis. First, 18 KSFs for implementing BIM have been specified by systematically investigating the pertinent literature and interviewing six well-qualified practitioners in BIM from Egypt, as a developing country. Second, from ten Egyptian BIM experts, data on the influences of the KSFs on each other have been gathered, employing a matrix format-based questionnaire. Third, the experts' evaluations have been processed, utilizing the Decision-Making Trial and Evaluation Laboratory (DEMATEL) technique. Proficiently, DEMATEL through its causal diagram portrayed the cause-and-effect relations map of the KSFs. Besides, it divided the KSFs into four clusters, each of which signifies a phase in the BIM implementation journey along with its corresponding priority as well as the priorities of the KSFs that it encompasses. The causal diagram indicated that phase one related KSFs of the BIM implementation journey: research and development investments, senior management support, and firm's fiscal support contribute to the whole success of the developed BIM implementation roadmap. This study equips construction practitioners in the developing economies with a four-phased roadmap for applying the KSFs of BIM implementation journey in practice on a step-by-step basis. This contribution helps in better prioritizing their decisions and optimizing the allocation of their resources when applying BIM in their business. Hence, at a fast pace, BIM can be proliferated in those countries.
