BIM is a modeling technology that allows architects and builders to visually create, analyze, and share building models. BIM is gaining a growing importance which may be reflected in the increasing number of owners who demand BIM use. However, despite the perceived uptick in demand for BIM, an industry wide adoption has not yet been reached. Likewise, the adoption of BIM enhanced business practices within both design and construction has been limited. While there are multiple barriers to BIM use, resistance to change has been identified by scholars as a major restraining force. Indeed, BIM prompts for substantial changes in the ways architects and constructors think and work which may question their performance and challenge their identities as competent workers. In this research, we address these dynamics, we use identity theory to gain an understanding on how identity accounts for acts of resistance and adoption of BIM in AEC industry.
