How Personal Background Shapes BIM Adoption: Linking Implementation Intentions and Concerns Through Behavioral Theory

Abstract

Background and aim - Experts have ignored construction professionals' (CPs) interest and concerns in uncovering BIM implementation, relying on the assumption that once BIM is promoted, it will be implemented. This study contends that CPs are critical actors in BIM implementation, and it investigates their concerns and intentions toward BIM implementation, as well as the impact of their intentions and personal background on their concerns.

Methodology - By combining the Theory of Planned Behavior (TPB) and the Concerns-based Adoption Theory (CAT), the study gained insight into the role of positive and proactive personality and psychological capital in the formation of BIM implementation intentions and concerns. The BIM implementation intentions and concerns of the CPs were linked and captured in three hypotheses. Multiple Linear Regression was used to test the hypotheses.

Results - The CPs were concerned about their services, professional knowledge, and investment in BIM resources. The CPs are eager to learn more about BIM, why it is being proposed, and what it means for them. All of the CPs' intentions were discovered to have an impact on their concerns. BIM implementation programmes allow time for individual experience and interest in BIM, as well as give CPs enough time to learn BIM and become comfortable with BIM cycles.

Conclusion - The study concludes that the CPs' intention to implement BIM will not be realised until all of their critical issues are resolved.
