Abstract
Abstract. The emerging field of digital fabrication is a process where three-dimensional datasets can be directly transferred to fabrication equipment to create models or even 1:1 building elements. In this paper, we will discuss the results of a collaboration between the Carleton Immersive Media Studio (CIMS), the Dominion Sculptor of Canada, and the Heritage Conservation Directorate (HCD) of Public Works and Government Services Canada (PWGSC), that utilizes digital fabrication technologies in the development of a digitally-assisted stone carving process. The collaboration couples the distinguished skill of the Dominion Sculptor with the latest digital acquisition and digital fabrication technologies for the reconstruction of a deteriorated stone bas-relief on the façade of the East Block building of the Parliament Buildings National Historic Site of Canada. The intention of the research is to establish a workflow of hybrid digital/analogue methodologies from acquisition through rehabilitation and ultimately to the fabrication of stone elements.
Highlights
Digital acquisition technologies such as laser scanning and photogrammetry have become integral to heritage documentation
Coupling the acquisition technology with digital fabrication technology can potentially expand the contributions of heritage documentation in the preservation of heritage assets
The monitoring of heritage assets (Salonia et al, 2011), the creation of 2-D line drawings (Angelini et al, 2011), online interactive models (Abate et al, 2011) and the creation of BIM models (Fai et al, 2013), is a non-exhaustive list illustrating the broad spectrum of uses for digital acquisition datasets
Summary
Digital acquisition technologies such as laser scanning and photogrammetry have become integral to heritage documentation. Coupling the acquisition technology with digital fabrication technology can potentially expand the contributions of heritage documentation in the preservation of heritage assets. The monitoring of heritage assets (Salonia et al, 2011), the creation of 2-D line drawings (Angelini et al, 2011), online interactive models (Abate et al, 2011) and the creation of BIM models (Fai et al, 2013), is a non-exhaustive list illustrating the broad spectrum of uses for digital acquisition datasets. Using the datasets from heritage recording for digital fabrication has had significantly less study. The fabrication of replicas for museums (Allard et al, 2005), (Cooper et al, 2006), and archaeological study (Fatuzzo et al, 2011), has been documented but the fabrication of substantive building materials as part of heritage conservation work is a nascent field
