L’entrata in vigore del DM 560, lo scorso dicembre 2017, ha introdotto in via obbligatoria la digitalizzazione degli appalti pubblici, la quale prevede l’adozione della tecnologia BIM dal 1° gennaio 2019 per opere superiori a 100 milioni di euro e gradualmente per quelle di minore importo fino al 2025. Inoltre il lavoro condotto da UNI, al fine di stabilire le linee guida italiane in ambito BIM, renderà presto obsoleta la modellazione bidimensionale CAD, generando così l’immediata necessità di un passaggio a questa tecnologia per gli studi di progettazione che ambiscono a mantenersi competitivi non solo sul mercato nazionale. Da recenti statistiche emerge che gli studi più strutturati stanno già affrontando questo cambio di paradigma legato principalmente alla fase di progettazione esecutiva; l’elaborato di tesi al contrario si propone di integrare questo approccio nell’iter progettuale fin dallo studio di fattibilità, momento cardine per la definizione degli obiettivi e delle caratteristiche estetiche, tecniche ed economiche. Tali scelte dovranno necessariamente essere rispettate per tutti gli step di avanzamento del progetto. A tal proposito, si può affermare che con il metodo tradizionale, il flusso di informazioni che governano il progetto non è sempre chiaro e condiviso da tutti gli attori coinvolti, determinando, a lungo andare, la perdita di informazioni chiave al fine di mantenere invariata la qualità dell’intervento. Pertanto si è sviluppato un modello tridimensionale il quale è la pre-costruzione dell’edificio in una realtà virtuale, che permette di identificare i problemi e le possibili soluzioni in via preventiva, tenendo conto dell’intero ciclo di vita del manufatto. Grazie all’implementazione della Work Breakdown Structure (WBS) nel modello BIM, ogni componente è identificato con un codice univoco, il quale rende l’elemento sempre riconoscibile in tutte le fasi del progetto. Queste premesse sono state il filo conduttore per la progettazione bim-based di un’unità abitativa, residenza prefabbricata modulare, a basso impatto energetico; inoltre sono state di supporto per lo sviluppo di un metodo facilmente replicabile, il quale consente di apportare cambiamenti di varia natura, con il conseguente adattamento del progetto alle specifiche esigenze di utenza e luogo. Tale metodo si dimostra dunque un utile strumento per la definizione delle componenti più indicate, considerando l’edificio nel suo intero ciclo di vita.

Abstract
The recent adoption of DM 560, which dates back to December 2017, introduced the obligation of digitalization for public calls to tender; from 1st January 2019 the new legislation requires BIM adoption for every project with a cost exceeding 100 million euros and gradually – until 2025 - it will also be applied to projects with lower costs. All of the work by UNI, that is meant to establish new Italian guidelines upon BIM, will soon let become traditional CAD modeling outdated and will hence generate a strong need for this new technology among design firms in order to stay competitive worldwide. The most recent statistics show that biggest national firms already started to face the transition to BIM, especially while developing the detailed design phases; on the contrary this thesis proposes BIM method’s application to projects right from the conceptual phase, which represents a key moment for the definition of design targets together with building’s aesthetic, technological and economic features. All of these necessarily need to be respected along the whole design process. Following the traditional method could in fact lead to a misconception of project details among all the involved stakeholders and the consequent loss of key information for the management of design final quality. In order to test the validity of the proposed approach a 3d model has been built, representing the virtual pre-construction of the building, which easily allows to detect project’s clashes and conflicts together with their early resolution and control along its whole life-cycle. Thanks to the implementation of Work Breakdown Structure (WBS) into the BIM model every single component is identified with a unique code, that allows its detectability through all design stages. These premises acted both as a common thread for the BIM-based design of a sustainable, modular precast housing unit and as a support for the development of an “easy to replicate” method; in particular it allows to make changes regarding the different themes embedded in the design, being therefore able of adapting to the specific needs of various users and sites. This method has proven itself of being a very useful tool for the definition of multiple ad hoc components during the entire building life cycle.File | Dimensione | Formato | |
