The intricacy of the construction supply chain and the interactions among various actors in construction projects highlight the important role of Information Technology capability and efficient information flow integration to guarantee seamless coordination and communication among stakeholders. This study investigates the association between Client/Owner, Contractors, supplier's Information Technology capabilities, and information flow integration. Regression analysis is used to examine the data and ascertain the relationships between these variables. The findings indicate that information flow integration, each entity's Information Technology capability, and construction project performance are positively correlated. Information Technology capability allows key players in a construction project to integrate information and ultimately improves the performance of construction projects. According to the research, better project performance may result from strengthening Information Technology capability and integrating information flow among the Construction Project's partners. The significance of investing in Information Technology Capability and encouraging efficient communication and cooperation between clients, contractors, and suppliers are important takeaways from these findings for patrons in the construction industry.
