The document discusses barriers to BIM implementation globally and in the GCC region specifically. Some key barriers in GCC include the traditional design-bid-build procurement strategy, unclear employer requirements, and the need for fast project delivery timelines. Adopting BIM also introduces changes to the roles and processes in the AEC industry. The document argues that a unified BIM standard for GCC projects should be adopted, with requirements defined and enforced by engaged employers to fully realize the benefits of BIM.
