However, BIM adoptions have not been 11 generally embraced by many Architecture, Engineering, and Construction (AEC) firms, 12 particularly in developing countries; and studies that investigate the important drivers to BIM 13 adoptions among construction professionals through quantitative approach are limited. The 14 study purpose is to address the aforementioned gap. 15 16 Design/methodology/approach -The study used a literature review, a pilot study and a 18 questionnaire survey. The primary data were carried out using structured questionnaire 19 distributed to the four different, selected BIM adopters' AEC firms. These comprised 20 architectural firms, facility management firms, quantity surveying firms and structural 21 engineering firms in Lagos, Nigeria. Data obtained were analyzed using mean score, standard 22 deviation, Kruskal-Wallis test, and factor analysis.23 24 Findings -The study identified 23 drivers to BIM adoption and the relative importance of 25 the identified drivers was gauged from each selected BIM adopters' AEC firm category. The 27 result of the Kruskal-Wallis test showed that there is no statistically significant difference in 28 the perceptions of the four selected AEC firms in the mean ranking of the identified 23 29 drivers to BIM adoption. The findings from factor analysis categorized the identified drivers 30 into two major factors to include: cost and time savings, a...
