The project of the reuse of an architectural environment must consider the set of residual services provided by the building. The activation of a documentation process allows you to be aware of what an environment offers. The spatial and material analysis of the current state must be accompanied by a material, technological and tech-system survey. In the case study of the Castiglioni Chapel in Pavia (Italy), the various diagnostic outputs were associated with the detailed survey, with the aim of planning interventions for the site conservation project. Conservation takes place both with physical actions and with museumization processes. The action methodology involved numerous phases such as detailed digital survey, technological analysis, and digitization through three-dimensional models. All the analyses carried out are integrated in an immersive virtual system structured by layers and scenarios. The chapel can be orbited with AR platforms, which allow you to enhance valuable frescoes and see the different levels of analysis in real time. All the processes underway in this project are aimed at making the space a place of knowledge with real and digital use.

Digital 3D reconstruction in architecture is a powerful tool for monitoring construction sites, tracking project progress, and ensuring quality control. This method involves the use of digital survey technologies, such as drones, laser scanners, and 3D modelling software, to acquire precise and detailed data on the construction process. If we consider surveying to be a phase of documenting the existing, it is possible to talk about an architectural census as the process of collecting and analysing data on buildings and structures. This information is crucial for management and planning, as it can help identify issues related to building safety, accessibility, and sustainability. The research project aims to quickly obtain a database of documentation and historical, dimensional, morphological, and material knowledge of a university building in the historic centre of Pavia that is now disused, to develop an information system for quick census and monitoring.

This research aims to define a low-cost replicable methodology for obtaining fast multiscale information models. The experiments carried out were conducted by researchers from Dada LAB and PLAY experimental Laboratories of the University of Pavia, Department of Civil Engineering and Architecture, on the case study of the irrigated landscape of the Pavia plain. The entire work process was developed according to a low-cost purpose, starting from fast acquisition activities with UAV instruments, to the processing of photogrammetric data, urban and detailed scale modelling with open-source software, to the census, filing, and computerisation of the model. The resulting product is configured as a multiscale reality-based information system. A census card is associated with each constituent element of the model (crops, canals, valuable hydraulic artefacts). Connection to the GIS platform allows the user to query the model. The result is a digital system oriented to facilitate the management of the agricultural and irrigation landscape, and to digitally document and preserve the heritage of historical hydraulic existing artefacts. Two different GIS platforms for structuring the information system were tested. The first involved a high-budget solution using ESRI ArcGIS Pro/ArcSCENE software, and the second involved using QGIS software, an Open-Source Geographic Information System, to develop an accessible information system without license fees, to evaluate the advantages and disadvantages of low-cost processes.

The present contribution illustrates the documentation and setting up of a digital database of a portion of Bellisomi-Vistarino Palace in Pavia (Italy), a relevant historical asset due to its artistic value. Despite recent restoration work, there are still disused portions of the complex, including the garden, the loggia and the rooms on the ground floor that overlook it. These portions are the elements this paper deals with. The approach to a small portion of the building is a pilot case from the perspective of a broader work of integral documentation of the whole complex. The aim is to define digital support for diagnostic and restoration planning activities from the perspective to enhance and create a new cultural attraction for the city, using the Foundation of the University of Pavia, already settled in the Palace and their organizational skills and networks. This is achieved by structuring a tridimensional digital twin and database connected to it to monitor the assets and generate digital environments for cultural and touristic valorisation.

This contribution presents a process of documentation and conservation of the built Cultural Heritage, tested on a partially disused case study located in the urban fabric of the city of Pavia. The actions defined led to the design and implementation of a tridimensional Information System obtained integrating data collected across different research areas, reality-based models and with the goal of enriching a tool for the documentation and management historical buildings owned by the University of Pavia. The process of documentation, three-dimensional digitisation, and census of the architectural elements on an urban and-architectural scale defines a tool for standardised analyses on building complexes of the same property and for large-scale planning of monitoring and valorisation activities. The research is based on the use of tridimensional Information System, as one of the indicators of the 2030 Agenda, in line with target 11/11.4, to activate a process of reuse and sustainable management of urban heritage.
