Abstract
Relocation of buildings has been a common practice for centuries and is now frequently used as a means to preserve heritage structures in the face of various economic, social, and environmental risks. In relocating a heritage structure, documentation is of the utmost importance because of the adverse effects that relocation can have. Reality capture technologies provide a powerful tool for rapidly recording real-world phenomena in three-dimensions but have yet to be utilized for the documentation needs of relocation projects. This thesis provides a novel example of these technologies used for not only documentation of, but in an assessment of the impacts of relocation at the Perrenoud Homestead Provincial Historic Resource (PHR). During its disassembly, the Perrenoud Homestead was digitally documented using terrestrial LiDAR (laser scanning) and drone-based photogrammetry. The resulting datasets were then used to explore the impacts of relocation to the structural integrity of the site, through a three-part analysis of visual inspection, angular measurements, and change detection. A discussion was then posed about the consequences of the project on the commemorative integrity of the site, looking at dynamics of reality capture and the physical components of the PHR, as well as changes to the visitor experience and accessibility of this site. Overall, this thesis presents an example of the benefits of reality capture technologies to heritage relocation projects, and advocates for more incorporation of these methods for similar initiatives in the future.
