This thesis investigates the critical success factors (CSFs) for the successful implementation of Building Information Modelling (BIM) in construction project management, with a focus on the digital transformation of traditional manual processes. BIM is a powerful tool that integrates multiple aspects of construction management, improving efficiency, collaboration and decision-making throughout the project lifecycle. Through an extensive literature review and the application of the Analytical Hierarchy Process (AHP), this research identifies and prioritises key criteria that influence the success of BIM adoption, including process improvement, strategic alignment, technology integration, organisational change management, regulatory compliance, and user training and support. The study highlights the significant benefits of BIM, such as improved workflow efficiency, reduced project duration, improved data accuracy and better alignment with organisational goals.
