Post-Pandemic COVID-19 Virtual Documentation Through 3D Laser Scanning and 3D Photogrammetry for Site and Building Assessment

Abstract

The pandemic has certainly become a paradigm shift in multiple sectors and industries, including the built environment. Therefore, this chapter highlights one of the methods which was adopted during the pandemic in continuing the architecture, engineering, and construction (AEC) practice without disregarding the site assessment due to the pandemic circumstances. This chapter is to discuss the potential of adopting 3D laser scanning and 3D photogrammetry in the making of a virtual site and building model for various purposes, including building inspections, virtual visits, and defect inspections. The case study of six projects is used to demonstrate the usage of the two methods: 1) 3D laser scanning, and 2) 3D photogrammetry. The results show the potential for the site and building assessment in adopting virtual advanced technologies pertaining to the post pandemic COVID-19 and various future circumstances and challenges in the field of the built environment.
