Representing Intangible Heritage: Questions Concerning Method

The research explores issues concerning the relation between text and images – an interesting field of enquiry little explored to date – involving archaeological heritage that has not survived and is therefore based on descriptions of artefacts and sites. Nowadays, this heritage can exist again thanks to digital technologies (relational databases) and methodologies (conceptual modelling) that allow the construction of 2D and 3D models. Studied here are the relations between the text and conceptual categories, between description and classification of objects in order to understand how all words and terms influence the results of interpretation and interaction between different profiles in the construction of models. In this context digital methodologies are discussed to assess the actual state of archaeological information systems and reflect upon possible future directions

The problem of identity in architecture towards globalization: the experience of the house in Moledo by Eduardo Souto Moura

Globalization creates cultural comes-and-goes around the world, promoting transitory, ephemeral and floating identities that we may call “hybrid identities”, which become the major characteristic of our contemporary world. So how do we deal with the huge pressure of worldwide architectural context whilst preserving our own character? What can we do to claim the diversity of architectural culture and the maintenance of local traditions? What methodological tools are available to avoid the alienation of nowadays’ architects from their traditions for the sake of genuine architecture? By analyzing the House in Moledo we’ll reflect on the identity of Portuguese traditional architecture and the way Souto Moura faces this topic. The houses he designs are the result of a long and arduous process of analysis, refinement and decision. It can be interpreted as a set of variations on a theme, like Mies van der Rohe did, resulting in a simplicity that isn’t easy to achieve. By observing the evolution of his research, it seems obvious that it comes down to a kind of pattern that reveals a specific typology. But what does it have to do with local architecture? In this house, six tons of stone were used in blind side walls, erected with irregular blocks of granite anchored in dry, supporting the place’s high demanding along a vast expanse of a steep hillside overlooking the Atlantic coastline through its terraced agricultural banks. By sustaining an outcropping of rock in the back of the house as an extra visual reaffirming, plus the link between the environment and the interior of the house, he praises the masonry work as the main value of its architecture. But is this enough to define it as Portuguese architecture? Through this experience, which achieved a harmonic architectural balance and its worldwide recognition as a farsighted case-study, we intend to reflect on the direct effects globalization induces on the local cultural identity, and the challenges we’re facing.This work has the financial support of the Project Lab2PT - Landscapes, Heritage and Territory laboratory - AUR/04509 and FCT through national funds and when applicable of the FEDER co-financing, in the aim of the new partnership agreement PT2020 and COMPETE2020 - POCI 01 0145 FEDER 007528.info:eu-repo/semantics/publishedVersio

Quality vs Quantity: Advantages and Disadvantages of Image-Based Modeling

In the last few years, survey has changed radically thanks to progress in the field of 3D, massive data acquisition methods. The scientific debate focuses on the control over data quality by comparing Structure from Motion acquisition methods with consolidated methods. Collecting and interpreting a large amount of information helps us deeply understand our cultural heritage. This system of knowledge that we create has to achieve a dual objective: to document heterogeneous data with guaranteed repeatability and to ensure data quality during data capture and model processing. This information includes cultural resource data: dimension, information on construction, material characteristics, color; etc. The case study, the Abbey of Santa Maria della Matina, focuses on the shift from quantitative data, acquired in a semi-automatic manner, to qualitative data, controlled under uncertainty. In this framework, all branches of the “Science of Representation” ensure metric, spatial, and formal control of the built models

HBIM come processo di conoscenza. Modellazione e sviluppo del tipo architettonico

Il volume raccoglie gli esiti di uno studio sulle potenzialità derivanti dall’integrazione del BIM (Building Information Modeling) nei processi di documentazione, comunicazione e gestione del patrimonio costruito, indagando l’estensione del concetto di modello digitale rispetto alla stratificazione della conoscenza resa possibile dall’approccio HBIM (Heritage Building Information Modeling). Il tema viene affrontato con un duplice obiettivo: delineare un protocollo operativo legato alle possibilità di gestione dell’architettura esistente, potenziate dall’integrazione con le metodologie per l’acquisizione massiva di dati, e condurre una riflessione riguardo quale sia la corretta impostazione dell’HBIM affinché possa considerarsi un vero e proprio metodo per la conoscenza, la lettura e l’analisi del patrimonio architettonico. La sperimentazione affronta questi problemi in relazione a diversi casi di studio appartenenti all’architettura rinascimentale e al razionalismo italiano che, sebbene afferenti ad epoche storiche e a stili differenti, hanno in comune importanti caratteristiche: la standardizzazione del tipo, l’impostazione progettuale basata sul forte rigore geometrico, la definizione di regole compositive basate sulla classificazione e la ripetizione degli elementi formali. L’approccio seguito considera gli aspetti strutturali, le soluzioni compositive e i caratteri formali, ripercorrendo il processo progettuale a cui è subordinata la realizzazione dell’architettura

Tradition and Innovation: From Worksite Plans to Digital Models

The study and analysis of archaeological elements often ranges from very large sites to small objects. This difference in size and type is also present during survey and representation. This idea sparked the proposed study of worksite plans that constitute the only firm link between historical architecture and its representation. The objective is to develop a new interpretation of worksite plans merging massive acquisition technologies with digital representation. The topic is associated with studies on the origins of architectural drawing based on the interdisciplinary union between architecture and archaeology. The objective is to critically interpret worksite plans in order to establish and classify a study methodology. Based on these premises, we examined the key relationship between the metric/formal construction of a 2D drawing (plan) with a 3D model (ideal model). The study is part of the now consolidated drawing/survey/design process which is based on objective/real drawings and leads to a 3D/ideal mode

Scomposizione e ricostruzione del patrimonio architettonico. La struttura dei processi HBIM tra rilievo e modello.

Numerosi studi nell’ambito del patrimonio costruito affiancano l’HBIM ai dati di rilevamento, pur non essendo ancora delineato un metodo di lavoro univoco. La presente ricerca identifica la scomposizione dell’architettura, basata su criteri strutturati, e la sua ricostruzione, attraverso modelli ideali, i momenti principali del processo HBIM. L’efficacia dell’approccio proposto viene potenziata legando tale processo ai dati di rilievo, per avere un continuo confronto tra modello di progetto ed as-built. La metodologia, applicata secondo un approccio crescente rispetto alla complessità degli edifici analizzati, confronta il processo seguito su due casi di studio, e viene valutata rispetto alle problematiche al centro del dibattito sull’HBIM: il rapporto tra la modellazione semantica e la continuità delle superfici che definiscono l’architettura esistente; la relazione tra la standardizzazione delle componenti e le irregolarità geometriche e materiche; l’affidabilità dei modelli costruiti e le valutazione dello scarto tra la definizione di un modello ideale, caratterizzato da una forte componente interpretativa, e l’oggettiva precisione del rilievo

L'architettura romana al tempo del BIM

Lo studio indaga la validità del processo HBIM nel complesso ambito dell’architettura archeologica. Individuare una varietà di elementi, comunemente utilizzati nel processo costruttivo, costituisce la base di una procedura che mette in relazione la loro riconoscibilità stilistica e geometrica con le azioni del tempo e le stratiicazioni

La struttura dei processi HBIM tra rilievo e modello. Scomposizione e ri-costruzione del patrimonio architettonico

Digital models have now become indispensable for all the activities that aim to the knowledge, documentation and planning of interventions on the existing architectural heritage. Currently, 3D modeling and data sharing allow to describe architectural structures as a complex process, based on geometric, cultural, historical, theoretical features, able to extend the knowledge of architectural assets. HBIM (Heritage Building Information Modeling) enrich the management of the existing reality and the design of interventions from the general to the detailed scale, through the complete interaction among different professional figures involved. This research aims to define the main critical issues of the HBIM in relation to the built heritage, trying to define its implications with the representation and optimizing the use of data obtained from the consolidated integrated survey operations. The focus is identifying the decomposition of the architecture, based on structured criteria, and its reconstruction, through ideal models, as the main moments in the HBIM process. The analysis of historical buildings belonging to different historical periods and with different formal and typological characteristics offers the opportunity to test the structure of the process, validating it and guaranteeing quality in all its phases
