Research on Collaborative Mechanisms of Railway EPC Project Design and Construction from the Perspective of Social Network Analysis

With the promotion of Engineering Procurement Construction mode in railway construction projects, collaborative management between design and has faced increasing challenges due to complexities participants various professional fields involved EPC projects. This paper aims analyze issues present project construction. Utilizing social network analysis methodology combined with Wuli–Shili–Renli (WSR) system methodology, a model was established explore relationships management. study investigates network-influencing factors proposes targeted measures enhance efficiency. The findings indicate that coordination communication mechanisms, organization building, interface systems represent core elements significantly impact These are closely related other factors. research not only advances theory, but it also introduces new ideas for engineering practice.
