New parametric objects
This number of Dienne has chosen the Digital Twin as the subject of its discussion, a development area that is intertwined with that of BIM, representing a first important evolution in terms of applications.
It is therefore very easy to find in the path leading to the completion of this more general theme, attempts to make the structure of the basic model dialogue with different data, which in fact oblige the implementation of increasingly advanced methods and tools to interface with complex relationships. .
These are the contents of this issue of Dienne; an issue that collects the best papers selected from those presented as part of the 3D Modeling and BIM conference held online on April 14, 2021, organized by Sapienza University of Rome where the in-depth study of HBIM applications crosses areas ranging from parameterization of degradation, to the creation of specific parametric objects, to the use of advanced methodologies through the VPL, to augmented reality applications for management.
The peculiarities of the BIM approach aimed at the recovery intervention on built heritage are highlighted in the contribution of Sara D’Ippolito, Laura Gianzi and Marzia Monaco which illustrates the experiments on the informative reliability of the model starting from historical surveys, information found on the web and digital surveys. In the same direction, the contribution of Chiara Vernizzi and Roberto Mazzi on the former prison of San Francesco del Prato in Parma which shows the maturity in the adoption of BIM processes for existing assets.
A critical evaluation of the BIM approach in the management and enhancement of museum heritage emerges in the contribution of Elisabetta Caterina Giovannini, Massimiliano Lo Turco and Andrea Tomalini who experiment with parametric and algorithmic approaches on the Egyptian Museum; the theme of the dissemination and conservation of cultural heritage, for a real-time visualization starting from an H-BIM model obtained from integrated digital survey techniques, is central in the contribution of Carla Ferreyra, Anna Sanseverino and Andrea di Filippo; on the other hand, the reflection conducted by Paolo Clini, Ramona Quattrini, Romina Nespeca and Mirco D’Alessio on the methods of narrating material and immaterial heritage leads to the innovative experimentation of mixed-reality techniques at the Rocca Torrione complex by Francesco Di Giorgio Martini.
Daniela De Luca and Francesca Maria Ugliotti experiment with the Digital Twin paradigm on Teatro Regio in Turin, configuring a dynamic and interactive model of the building that provides for a constant interaction between real and virtual space.
The working group made up of Andrea Bongini, Vincenzo Donato and Carlo Biagini faces the potential and current limits of some BIM-based approaches in the field of Facility Management by comparing two different processes for the acquisition and management of the parameters necessary for the phases of asset management of existing school buildings
In the context of historical heritage, both at the architectural and urban scale, the issues relating to the assessment of seismic vulnerability and post-earthquake management are of great interest, which require the collection and systemization of heterogeneous data, also through Visual Programming Languages, for the creation and implementation of H-BIM workflows as in the case of the contribution of Filippo Calcerano, Letizia Martinelli, Michele Calvano and Elena Gigliarelli or of an approach to the urban scale as reported in the contribution of Federico Mario La Russa and Giulia Genovese for the creation of a responsive City Information Modeling.
Finally, the contribution by Anna Mangiatordi illustrates the development of a digital model of assisted living for the elderly for the control and management of information flows related to the insertion of Artificial Intelligence systems into the environment, through a BIM data sharing platform based on on open and interoperable information processes.
In the continuation of the next issues, the ongoing evolutionary process that pushes BIM beyond its first vocations will certainly be able to carry on all the research areas undertaken up to now and show us how fertile and interesting developments are here.
