MUST tests and enhances a participatory service for the maintenance and management of the built heritage. The application, designed to acquire and organize the information collected by users by connecting a database of failure processes to the network, represents an opportunity for sharing with the established community according to an open data and citizen science perspective capable of contributing to the optimization of maintenance planning processes.
Over time, guaranteeing a pre-established quality for the built environment, by predicting and preventing performance modification processes is, in fact, a commitment that calls into question the development of a culture and maintenance practice based on control and planning. In this context, digitalization supports the reorganization of management coordination services at the building and urban scale, redesigning roles, relationships and synergies between expert knowledge, technicians, administrators, users. The lengthening of the life cycle of buildings is a MUST for the community, to which the application responds with the expanded sharing of knowledge and programming.
The MUST application, aiming at new ways of using the built environment and at the renewed expectations of the settled community in terms of safety and willingness to invest in the treatment actions, configures a complex redesign of the maintenance coordination service based on the paradigms of culture sharing:
 mutual trust; the spread of methods of shared use of the asset is accompanied by a direct sensitivity of the subjects towards maintenance, regardless of the use of a third party called to perform the role of manager or judge;
 sharing of knowledge and tools, as an opportunity to multiply energies and resources; the same service is enriched in content and improves with practice;
 peer to peer relationship, overcoming traditional intermediaries and established service delivery channels; the user is able in real time to reach the manager of the maintenance service and interact with the technicians.
