The undeniable ability of axonometric and perspective views to convey information related to the spatial perception of the city has been recovered using 3D models [23]. The transition from analogue to digital, both in the acquisition and restitution phases, makes it possible to create, in a short time and with millimetric precision, a three-dimensional model of the existing artefact (digital twin) 14 on a 1:1 scale on which, a posteriori, it is possible to link databases containing information on different areas. ...

The documentation of urban morphology is linked to the complex operation of representing the city, which over the centuries has been undertaken using different methodologies, instruments, and purposes. The “IT revolution” has expanded the possibility of overlapping and relating multiple pieces of information in connection to the urban organism on the same support and, on the other hand, has opened up new scenarios linked to the use of urban digital twins to support the analysis and urban planning. The 21st century has marked a momentous turning point compared to the recent past: the advent of artificial intelligence has in fact allowed the introduction, alongside Urban Information Systems, of ‘Predictive’ Systems, capable of formulating new scenarios on the basis of the elements available and pictured on 3D models. At the same time, the technical and technological acquisitions of the last century have contributed to evident experimentation on the metaverse, which, although it still exists in a de-emphasised form, is currently a whole universe under construction and expansion. Its rules are written with every passing day, in which the individual can recreate a reality similar to, or absolutely antithetical to, the one they experience on a daily basis, populating virtual cities that elude the established urban dynamics of physical structures.

Thesis
Full-text available
The aim of the thesis is the definition of a parametric modelling methodology that allows, in a short time and at a sustainable cost, the digital acquisition, modelling and analysis of urban aggregates with the aim of facilitating seismic vulnerability mapping actions in historic centres. The research involves the use of direct data (site surveys) and derived data (available geodata) for the realisation of a parametric City Information Model (CIM). Grasshopper, a Visual Programming Language (VPL) within Rhinoceros, already widely used in the scientific community, was chosen as the working environment for the parametric computational design. The methodology consists of several progressive steps that can be pursued through two innovative methods (Survey-to-CIM and Scan-to-CIM) defined and developed in this thesis. The choice of which method to adopt depends on the availability of project resources and the type of urban centre being studied. The first method, Survey-to-CIM, is intended to be a low-cost solution that integrates different data and acquisition techniques (direct survey, photo-rectification, expeditious 360 photogrammetry, Street-Level imagery, etc.) within a parametric and responsive flow useful for smaller urban centres and without the need for special professional skills. The second method, Scan-to- CIM, is developed to automate the cognitive operations of interpretation and input of survey data performed by the surveyor. This task is carried out by an Artificial Intelligence system that uses Machine Learning techniques (in particular Random Forest) to identify remarkable geometric-architectural features (openings, walls, stringcourses) within point clouds obtained through digital surveying. Both methods lead to the definition of a parametric CIM system developed in VPL. The generated CIM model is equivalent to the definition of a semantic 3D City Model since all generated geometries, from the envelope to the interior, adhere to a semantic structure that defines relationships and dependencies. Since there are no guidelines in literature regarding the semantic structuring of city models in a parametric environment, an innovative format defined CityGH is proposed in this thesis. Based on the CityJSON standard, it proposes the same semantic structure of CityJSON but adapting it to the Data Structure of Grasshopper (Data Trees). This format is therefore proposed as an interchange format within parametric models to facilitate their dissemination and application. Thanks to its semantic structure, the parametric CIM model is capable of storing attributes and metadata that are fundamental steps in facilitating the beginning of the FEM analysis activities. The parametric CIM model defined so far also allows the extraction of structural geometric models, both NURBS and MESH, necessary for the execution of FEM analyses. In particular, a workflow was developed in the thesis that allows FEM analysis both within the VPL environment (Karamba3D, Alpaca4D - OpenSees plugins) and in external software dedicated to structural analysis (SAP2000, FEM-Design).

Historical centers represent the outcome of transformations and stratifications of the cities across the centuries. The knowledge of a historical urban environment requires an analytical methodology articulated on several interconnected levels of investigation to model a multi-layered complexity that encompasses the geometric and stylistic features of places (blocks irregularities, narrow streets, stratified buildings), the accessibility (pedestrial zone, no flyzone), the use of existing data (GIS, cartographies). Today the challenge for historical centers is dual: on the one side to make use of expeditious technologies to acquire data, on the other one to create 3D city models that allow to manage, visualize, enquire and use these data in a unique digital ecosystem. Our research deals with a multi-sensor data acquisition, evaluation and integration with the aim of creating informed and responsive 3D city models (CIM) that constitute a synthesis of the survey conducted and become the support for simulations in various contexts (seismic risk, hydraulic, energy performance).

The contribution concerns the development of methods and protocols for the monitoring of historical built Cultural Heritage with an integrated multidisciplinary approach consisting of documentation activities and analysis procedures. In particular, the latter concern the state of the art, morphology, construction technologies, and the conservation state of materials and construction packages, to structure the corpus of knowledge of the asset under examination. The analysis procedures aim to understand the spatial components of the structure in relation to construction, technological, and material aspects, and to define the digitization actions to be activated on the artifact based on the observed condition. Understanding and monitoring of the cultural asset is achieved through the construction of synthesis frameworks, functional for describing its complexity, which culminate in the use of semi-automated and automated censusing systems of Information Systems for the formulation of monitoring protocols and programmatic frameworks for management.

Il contributo presenta l’esperienza di un gruppo di lavoro che ha avviato e costituito la scuola torinese per il rilievo urbano e ambientale, fondata da Augusto Cavallari Murat al Politecnico di Torino nella prima metà degli anni Sessanta del secolo scorso. L’allora Istituto di Architettura Tecnica del Politecnico di Torino (già Dipartimento di Ingegneria dei Sistemi Edilizi e Territoriali, ora Dipartimento di Ingegneria Strutturale, Edile e Geotecnica) mise allo studio alcuni piani di ricerca accettati e finanziati dal Consiglio nazionale delle ricerche negli anni 1962-1966. Il pretesto era individuare le leggi generative e alternative dei tessuti urbanistici metropolitani, ossia di grandi città europee, e ricondurre tali leggi a schematizzazioni e significazioni più generalizzabili di quanto presente nella letteratura tecnica e storica in quel momento esistente. Cavallari Murat è uno studioso che si applica a diverse discipline. Cresciuto nella scienza e nella tecnica delle costruzioni, i suoi interessi sono stati ampliati all’architettura, alla composizione e alla documentazione architettonica, all’urbanistica, alla sociologia e alla statistica, all’arte. Compendia quindi conoscenze e interpretazioni date da un bagaglio di conoscenze vasto attraverso il linguaggio grafico e la diagrammazione con un approccio sistemico al rilievo urbano, che si rafforza nella interdisciplinarità; la cartografia urbana è uno degli strumenti che sceglie per condividere la ricerca.

This research proposes a parametric modelling methodology based on Visual Programming Language (VPL) for creating City Information Models (CIM) to facilitate seismic vulnerability mapping in historic centres. The methodology consists of two innovative methods (Survey-to-CIM and Scan-to-CIM) developed for integrating direct and derived data, using Grasshopper as the VPL parametric computational design environment. The Survey-to-CIM method is a low-cost solution for small urban centres that integrates different data acquisition techniques within a parametric and responsive flow. The Scan-to-CIM method automates the input of survey data using an Artificial Intelligence system that identifies geometric-architectural features within point clouds. The generated CIM adheres to a specific semantic structure defined as CityGH, an innovative format based on CityJSON 3D city model standards but adapted to the data structure of Grasshopper. The semantic structure of the CIM model allows the storage of attributes and metadata that facilitate the information enrichment and management. The CIM model also allows the extraction of structural geometric models (city block scale) necessary for FEM analysis. Specifically, a workflow was developed to enable FEM analysis in the same VPL environment. Overall, this methodology offers an efficient and sustainable approach for creating CIMs that can support seismic vulnerability mapping and analysis actions in historic centres. This research demonstrated the benefits of adopting an explicit parametric modelling approach for City Information Modelling, enabling to manage digital urban survey data, semantic enrichment and management and FEM analyses. The proposed methods can be pursued based on the availability of project resources and the type of urban centre being studied. The outcome of this research contributes to the debate about parametric urbanism and the role of computational design with CIM methodology. Specifically, the case studies developed offer a practical alternative for seismic vulnerability mapping in historic centres.

Let us imagine a large sports facility and an integrated system to control its maintenance (structures, facilities, furnishings, communication systems), pre-configure temporary set-ups, procurement of goods and materials, check compliance with technical regulations concerning the safety and regularity of sports and recreational events, contracts with sponsors and suppliers, and the work of technical staff. Then, let’s imagine that this mass of data is supplemented by tracking the flows of people attending events, recording their behaviour through the looks they make, the stops they make, the actions they take. This is the theme of the contribution proposed, an experimental application involving a sports facility of international importance and integrating BIM processes for design and maintenance, social and commercial information systems open to the public, marketing and usage analyses based on sensors and big data, and artificial intelligence capable of prefiguring the safest and most comfortable solutions.
