Methodological Aspects of Architectural Documentation

Abstract

This paper discusses the methodological approach that is being developed in the state of Bahia in Brazil since 2003, in architectural and urban sites documentation, using extensive digital technologies. Bahia has a vast territory with important architectural ensembles ranging from the sixteenth century to present day. As part of this heritage is constructed of raw earth and wood, it is very sensitive to various deleterious agents. It is therefore critical document this collection that is under threats. To conduct those activities diverse digital technologies that could be used in documentation process are being experimented. The task is being developed as an academic research, with few financial resources, by scholarship students and some volunteers. Several technologies are tested ranging from the simplest to the more sophisticated ones, used in the main stages of the documentation project, as follows: work overall planning, data acquisition, processing and management and ultimately, to control and evaluate the work. The activities that motivated this paper are being conducted in the cities of Rio de Contas and Lençóis in the Chapada Diamantina, located at 420 km and 750 km from Salvador respectively, in Cachoeira city at Recôncavo Baiano area, 120 km from Salvador, the capital of Bahia state, and at Pelourinho neighbourhood, located in the historic capital.

HBIM Development of A Brazilian Modern Architecture Icon: Glass House by Lina Bo Bardi

“…Several studies have been developed focusing on heritage documentation workflow [16][17][18][19][20], which were important references for the methodological planning of HBIM development for Casa de Vidro. Casa de Vidro's HBIM was developed considering the following steps: modeling planning; data acquisition; model elaboration; pathologies and damage recording; data management; management and process documentation.…”

“…The stage of planning should consider all the objectives and resources to be embraced [20]. The information modeling must be guided by the intended use of the HBIM model.…”

“…Data acquisition involves the capture of primary data on-site and the compilation of secondary sources of information [20]. According to [11,21], surveying existing buildings is a reverse engineering process, as it is developed after the building is established.…”

“…At this stage, the raw data collected on-site was turned into the desired end products [20]. It involved processing, analyzing, and manipulating information to generate outputs.…”

“…After processing the data, outputs must be indexed, stored, published, and distributed to ensure that they can be reused in the future [20]. In this sense, the HBIM model creates a record of historical research, as it encompasses both geometric data and metadata, improving data management.…”
