BPMN 2.0 to Redefine Italian Design-Bid Procurement in an Innovative Model-Based, Open-Source Approach

An inherent complexity characterizes the construction industry with struggling information management, worsened by low digitalization, lack of interoperability, and formalized processes.The digital transition of process management is crucial to define data-driven tools, enabling consistent information creation, sharing, and exchanging.The paper focuses on the Italian Design-Build procurement, exploiting BPMN 2.0 to propose its redefinition in a model-based, opensource approach.It aims to provide a breakthrough, unlocking the still under-exploited potential of BIM and digital tools.Information exchanges can be identified, and also bidding models information requirements.The innovations introduced are discussed, highlighting how efficiency, transparency, and consistency can improve.
