PARAMETRIC PARADIGMA: EXCEPTIONAL COFFERED CEILING ARCHITECTURE VS HBIM

The scientific community is confirming the advantages of using BIM in the processes of conservation, management, and intervention over architectural-historical heritage. However, many difficulties remain in the transcription process of elements of the built environment, especially when the objective of the model is to support decision-making processes in restoration operations. Even for apparently simple elements, the procedures are not trivial; the need to define the most adequate operational strategies remains. In the context of this study, a possible approach concerning the documentation of a coffered ceiling has been proposed, a case study which takes into consideration the need to discretize information (to make it effective, transmissible, and understandable) and the potential offered by the combined use of further software automatization

HBIM (Historical Building Information System) represents a very promising tool for the management of Cultural Heritage, both for daily operations and for the planned preservation of the asset itself. However, it requires a specific effort to adapt tried and tested tools and methods for new construction to existing Cultural Heritage buildings. First of all, the starting point of the process (new construction projects versus surveys of existing buildings) changes, and consequently the requirements for geometric and informative modelling change. Especially in the field of Cultural Heritage, an in-depth and reasoned design of such (geometric and informative) models is necessary, to respond properly to the needs identified in the processes for planned conservation. To this end, an appropriate semantic classification of the building elements must be carried out prior to modelling, taking into account both documentation and geometric description requirements. The aim here is to propose a system for managing the information component of the model that takes its cue from the internal logic of BIM (Building Information System) Authoring (Autodesk Revit©) software and takes into account the operating practices of professionals in the conservation sector. In particular, a system which no longer takes into account the traditional two-dimensional classification of elements, but which directly affects threedimensional technological elements is proposed. This is the case of the remains of the convent of S. Maria, near Lake Garda, where the geometric modelling was structured according to this new model of management of information content. In this way it was possible to give a complete description of the reality of the building (and its surroundings), making it more usable and readable by the operators

HBIM for Planned Conservation: A New Approach to Information Management

Laboratório HE.SU.TECH.: pesquisa acadêmica combinada com a prática aplicada na documentação, representação e preservação do patrimônio arquitetônico - o caso da Villa Forni Cerato de Paladdio

Este artigo traz um estudo aprofundado sobre documentação, representação e práxis de conservação do patrimônio arquitetônico no campo da pesquisa acadêmica aplicada. A ênfase são os avanços tecnológicos na documentação digital aplicada ao Patrimônio Cultural. Destaca-se a importância em se conciliar o conhecimento da pesquisa acadêmica com o trabalho técnico aplicado. O mapeamento arquitetônico é uma das primeiras ações realizadas no processo de conhecimento de um bem e, como tal, ele torna-se imprescindível para as subsequentes operações de conservação, restauração e gestão. Este artigo apresenta uma experiência de técnicas integradas de mapeamento digital para a digitalização de uma arquitetura de Andrea Palladio: a Villa Forni Cerato. Esta experiência foi realizada pelo Grupo de Pesquisa Heritage Survey Technology (HE.SU.TECH.) do Politecnico di Milano - Polo di Mantova que desenvolve atividades de pesquisa e consultoria com instituições ligadas ao patrimônio italiano desde 2000. O caso da Villa Forni Cerato é particularmente interessante porque, neste caso, a digitalização foi integrada com outras fontes documentais, tais como as plantas e secções originais da própria Villa. O levantamento da Villa exigiu a integração de muitas tecnologias diferentes usadas no campo geomático para o Patrimônio Cultural. Este estudo de caso, em particular, tornou-se uma oportunidade para testar técnicas fotogramétricas com diferentes conjuntos fotográficos, adquiridos tanto do solo como por meio de Sistemas Aéreos Não Tripulados (UAS). Este trabalho tem sido objeto de discussão dentro do projeto de intercâmbio entre as duas universidades: Politécnico de Milão e Universidade de São Paulo.This article runs an in-depth examination of documentation, representation and conservation praxis of Architectural Heritage in the field of applied academic research. The focus is put on technological advances in digital documentation applied to Cultural Heritage. The architectural survey is one of the first actions taken in the knowledge process of an asset and, as such, it becomes essential for subsequent conservation, restoration and management operations. This paper describes an experience of integrated digital surveying techniques for the digitalization of an architecture by Andrea Palladio: Villa Forni Cerato. This experience has been carried out by the Heritage Survey Technology (HE.SU.TECH.) Group, from Politecnico di Milano - Polo di Mantova that has been carrying out research and consulting activities with institutions related to Italian Heritage since 2000. The case of Villa Forni Cerato is particularly interesting because, in this instance, digitization was integrated with other documental sources. The survey of the villa required the integration of all the different technologies used in the geomatic field for cultural HeritageThis case study, in particular, became an opportunity to test photogrammetric techniques with different photographic sets, acquired both from the ground and by means of Unmanned Aerial Systems (UAS). This work has been the subject of discussion within the exchange project between the two universities: Politecnico di Milano and Universidade de São Paulo.Este artículo trae un estudio en profundidad sobre documentación, representación y praxis para la conservación del patrimonio arquitectónico en el campo de la investigación académica aplicada.
