L’HBIM (Heritage Building Information Modelling) assume sempre

The Papal Basilica and the Sacred Convent of Saint Francis in Assisi in Italy are characterized by unique and composite particularities that need an exhaustive knowledge of the sites themselves to guarantee visitor's security and safety, considering all the people and personnel normally present in the site, visitors with disabilities and finally the needs for cultural heritage preservation and protection.

The research is oriented towards the definition of appropriate methodologies useful to seize the opportunities that the paradigm of industry 4.0 offers to the building industry.

The disruptive factor of the current industrial sectors is the constant spreading of ICT technology into produc-tion cycles. Following this trend, several companies improved their productive factors towards the optimiza-tion of processes through the digitalization of themselves, also thanks to public and private funds.

The construction sector is, currently, one of the most important sectors of the world
economy, although it is managed by dated systems compared to innovation that pervades
other sectors such as, for example, the automotive. Till now, in fact, it is estimated that
about 30% (McKinsley, 2017) of resources globally used in these processes, is dissipated
due to management inefficiencies, which can be found both in the design phase and in the
executive as well.
This inefficiency is not a new problem, but a constant condition in the construction realm,

L’industria delle costruzioni, attanagliata da una persistente crisi, ha nelle opportunità date dalla rivoluzione digitale l’occasione di efficientare l’intero comparto. Tali opportunità non sono insite tanto negli strumenti, quanto nelle innovative metodologie di gestione dei processi, legate agli sviluppi delle tecniche di intelligenza artificiale. Nell’articolo si presenta dunque l’elaborazione di un prototipo di integrazione tra Agenti autonomi e BIM: il risultato è la simulazione di alternative progettuali, a seconda delle diverse possibilità di ottimizzare le risorse a disposizione.

New opportunities nowadays provided by the introduction of highly sophisticated software tools have not brought yet to a substantial change in the design process still anchored to old traditional paradigms. Design activity is still rigidly organized in 'boxes', defined by semantic barriers. To support the designer's activity, improve communication, predict building behaviour and performance a new generation of simulation a support system tools seem necessary. To this aim, a general support system framework based on the Swarm Simulation Modeling approach is presented.

Nowadays, the building process shows a low success rate in terms of reliance of imposed time and cost forecasting. The causes are multiple: the lack of collaboration between the actors, the use of tools not suitable for managing the complexity of the contemporary building, the fragmentation of the market and an overall technological delay in production techniques, still linked to a "craft" vision of the building or anchored to a vision of the industrial system of the second or third industrial revolution.

The di.FM (Digital for Facility Management) protocol is an innovative approach for maintenance management, through the creation of a digital twin interconnected to the existing building. The goal is to create a BIM model that is constantly updated on the
state of the building, therefore capable of collecting related information and monitoring the state of use of the elements and components present.

The opportunities provided by the introduction of IT tools into the building process have not brought yet substantial changes in building design process, which is still
