The construction industry is rapidly changing due to Industry 4.0, with new technologies impacting supply chain management. However, the specific effects of computing, digitalising, and integrating tools on construction supply chain performance are not yet clear. This study explores how these technologies interact using survey data from construction professionals and path analysis. The findings show that computing technologies significantly improve performance areas like cost efficiency, flexibility, and reliability. Integrating technologies, which include IoT, RFID, and machine-to-machine communication, also have positive impacts on responsiveness and coordination. In contrast, digitalising technologies, such as augmented and virtual reality, and mobile applications, show limited effects because of issues with compatibility and implementation. These results underline the need to focus on well-developed and strategically relevant technologies to see real improvements. This study contributes to both theory and practice by clarifying how Industry 4.0 tools affect performance and providing guidance for construction firms responding to digital transformation.
