High fragmented and hardly accessible information often leads to struggling management of diffused assets. BIM and GIS integration is promising to develop effective digital Asset Management Systems (AMS) to facilitate information sharing and collaborative management. This paper presents a replicable methodological approach to develop a pilot BIM-GIS, web-based AMS for the University of Turin. The main aim is to overcome document-based and fragmented management, avoiding ineffective decisions during the operational and maintenance phase. The key step of integrating data from several heterogeneous sources in an accessible, centralized database is deep in described. Furthermore, two demonstrators are illustrated, discussing the first results and AMS potentials.

Digital Twins (DTs) and process digitalization are promising to bridge the gap towards Product Lifecycle Management (PLM) in construction industry. In a PLM view, DTs should born in the early design as virtual Prototypes (DTPs) useful as the basis for future DT Instances (DTIs) to manage the whole lifecycle. DTPs could help to overcome a discrete project performances view and enable an holistic one, exploitable for bids evaluation besides performance and sustainability optimization. The research adopts a PLM view to define a methodology aimed at developing a DTPs System which could lead a disruptive change in tenders evaluation, enhancing Green Public Procurement adoption.
