El levantamiento arquitectónico del patrimonio construido. Un instrumento preciso de la realidad

Nelson Melero Lazo — Wed, 28 Dec 2022 00:00:00 -0300

El levantamiento arquitectónico de un edifi cio constituye el instrumento básico
e indispensable para garantizar una adecuada intervención en un bien de valor
patrimonial. No solo conforma la base documental técnica, sino que también
defi ne, en gran medida el desarrollo y el éxito de todas las etapas posteriores
de trabajo. Para la realización de estos trabajos se han utilizado a través del
tiempo diferentes instrumentos y medios, los que han ido evolucionado con
el desarrollo del conocimiento y de la tecnología, encaminados a alcanzar cada
vez mejores resultados que refl ejen de manera más exacta la realidad que se está
documentando. Este proceso transcurrido entre la realización de los trabajos
de levantamiento de forma tradicional a uno más desarrollado digital, y sus
resultados prácticos obtenidos, son analizados en el presente trabajo.

La digitalizzazione del patrimonio come strumento per la conoscenza, un’esperienza sull’architettura ferroviaria siciliana

Sara Morena, Laura Barrale — Wed, 28 Dec 2022 00:00:00 -0300

The process of digitisation of the artistic and cultural heritage has enriched the possibilities
of representation and communication of architecture, increasing the modes of reproduction,
fruition as well as the possibilities of protection and preservation. The study of this research
draws attention on the continuous progress of technology in the cultural fi eld and highlights
the important collaboration that exists between digital and analog representation, identifying,
with this synergy, a virtuous path that allows, through the use of different methodologies, to
be able to know and analyze the historical phases of a building. In particular, the attention
was directed to the Caltanissetta Centrale station, a signifi cant junction of the Sicilian railway
network both for the connection of the island and for the sulfur trade. With its late modernism,
the station under study is part of the story of Art Nouveau stations in Sicily, and it becomes a
witness to economic and social changes in the region, thus making itself an asset to be protected
and disseminated. Through the study of iconographic documents, historical photos, and graphic
analysis it was possible to retrace, through a backward process from the laser scanning survey to
the study of photographic restitution, the main historical phases that characterised the evolution
and extension of the factory. Through such 3D graphic representations, it was also possible to
reproduce the characteristics of the building and highlight the changes that occurred over time
and the evident divergences that existed between the building and the original design idea.

Narrar la arquitectura y el ambiente: el dibujo del pensamiento y las emociones

Pia Davico — Thu, 29 Dec 2022 00:00:00 -0300

Cada dibujo es una narración, compuesta por signos, colores, transparencias,
relaciones entre las partes; en cada dibujo se crea un equilibrio entre imágenes
y pensamientos capaces de establecer un nexo entre el espíritu del ejecutor y el
de los observadores. El realizado a mano, gracias a su personalidad y unicidad,
y a la capacidad de crear una relación entre la materialidad y la inmaterialidad de
imágenes y pensamientos, todavía hoy se revela un instrumento de comunicación
indispensable e insustituible; su narración e interpretación se amplifi can
dependiendo del modo en el cual cada persona recibe los estímulos visuales y
emotivos transmitidos por el dibujo mismo.
Aunque el advenimiento de representaciones digitales cada vez más innovadoras
hace que se ponga en discusión, el dibujo del boceto constituye, y todavía sigue
siendo (lo documentan muchos estudios recientes), un elemento fundamental
para el arquitecto, gracias a su inmediatez y las vibraciones interpretativas
implícitas en el mismo, defi niendo un vínculo indisoluble entre pensamiento
y gestualidades gráfi cas, y transmitiendo además de los aspectos formales,
pensamientos y emociones.
La intención de esta aportación es poner en evidencia el modo en el cual dicho
vínculo resulta basilar en el lenguaje arquitectónico, tanto en el proyecto como
en el estudio de lo existente, para transmitir los puntos fundamentales de
arquitecturas o de espacios urbanos, y las implicaciones emotivas instauradas
entre el hombre y el ambiente.
Tomando como referencia cultural los bocetos de proyectistas que han dejado
un signo en la historia de la arquitectura contemporánea, y al mismo tiempo
mediante el análisis de algunos ejemplos de arquitectos menos notos, surge de
manera evidente el modo en el cual todos “fi rman” su dibujo mediante un
estilo personal de concebir el espacio y de expresarse utilizando precisamente
el dibujo como instrumento de comunicación capaz de subrayar los aspectos
peculiares de la construcción y del ambiente. Una confi rmación, por lo tanto, del
papel insustituible del boceto arquitectónico como manifestación del articulado
e indisoluble proceso que une la mente y la mano.

Sistemi di documentazione per scavi archeologici preventivi: piattaforme GIS per la gestione dello scavo del Santa Margherita a Pavia

Francesca Picchio, Francesca Galasso, Giulia Porcheddu — Wed, 28 Dec 2022 00:00:00 -0300

This paper discusses methodological aspects by illustrating the fi rst products of a research
project developed as part of a collaboration agreement between the DICAr - Department
of Civil Engineering and Architecture of the University of Pavia and the enterprise GEA
s.r.l. Archaeology, for the documentation of the archaeological excavations in the former Santa
Margherita Institute in Pavia (Italy). The activities, carried out by the experimental laboratories
DAda-LAB and PLAY, regarded the documentation of the archaeological evidences, dating
back to the 4th century AD, brought to light by the interventions of conversion and remodelling
of the historical and architectural complex. The need to produce documentation apparatus to
support the excavation activities is boosted by the fragility of the archaeological site, apparently
meant to disappear to allow space for the construction of an underground car park.
The research aims to develop a methodology for the organisation of the data acquired in the
multiple excavation campaigns, the production of databases useful to archaeologists for the
chronological interpretation of the excavation, the detection of archaeological emergencies and
the development of an information system that combines models and databases. Since March
2022, data acquisition campaigns have been undertaken to progressively survey the phases of
excavations. Data sheets were then developed for stratigraphic units and deposit units, and
an effective GIS system was developed to represent the complex nature of the site by making
clear the relationships between the stratigraphic units. The fi rst results of the research outline a
methodological process that leads to the development of a digital ‘container’ in which it becomes
possible to include the data collected during the campaign by reducing the time gap between
acquisition, recording, processing and synthesis of information.

La documentazione del patrimonio culturale perduto mediante fotogrammetria e intelligenza artifi ciale

Francesca Condorelli — Mon, 20 Feb 2023 00:00:00 -0300

This research aims to give an analysis and assessment through the extraction of metric
information from historical images and to experiment with its potentialities in the heritage fi eld
with the aim of valorising historical iconographical documentation. In particular the paper
deals with photogrammetry applied to historical images. A classifi cation and a state of the art
of historical archives material considering their possible use in metric documentation and thus
suitable for photogrammetry is performed. A photogrammetric workfl ow is proposed to process
historical images and the maximum metric quality level reachable by the photogrammetric
processing is investigated. Two case studies in Paris were chosen: the UNESCO Heritage
Tour Saint Jacques and the pavilions of Les Halles of the architect Victor Baltard. The two
studies represent different situations of heritage because the tower was transformed over time
but still exists and the pavilions were destroyed in 1971. Thus, it is possible to compare the
different results obtained from the implementation of the workfl ow to the two case studies.
