The Construction is an industry that depends on interorganizational relationships to enable its product. Most of the projects are held from networks, especially those for large scale projects of infrastructure, with flexible relationships for cooperation, and the modus operandi of virtual enterprises. However, there is a lack of studies on the analytical approach of networks considered their life cycle and the operation and reconfiguration phases for these large projects. The paper aims at developing a Reference Model for the phases of operation and reconfiguration of a construction network, specifically a subway infrastructure project. The model used a development process and is represented with the EKD Methodology (Enterprise Knowledge Development). A Case Study was used as reference. The Model enables the coordination of network activities from the perspective of collaboration. Other research opportunities emerge aiming at obtaining advances in scope and scale, considering this Case Study as an initial effort.
