The Architecture, Engineering, Construction, and Operations (AECO) industry lags in digital adoption despite its potential to enhance productivity and efficiency. This study develops a roadmap for digital transformation within the AECO sector, informed by both a thorough literature review and a survey of industry practitioners across various geographical regions and project types. The research examines challenges hindering digital progress, including low research and development spending, resistance to change, and a skills gap in digital technologies. The study investigates how digitalization challenges differ across various company sizes and project types, including residential buildings, infrastructure, and specialized infrastructure. The proposed roadmap outlines key steps for successful digital adoption, encompassing strategic planning, technology selection, skills development, and process optimization. Emerging technologies like Artificial Intelligence (AI), Virtual Reality (VR), and digital twins are explored for their potential to revolutionize construction practices and enhance productivity. Insights from this research provide a practical guide for AECO stakeholders to overcome barriers to digital adoption and accelerate their digital transformation journey, leading to improved efficiency, collaboration, and sustainability within the industry.
