| dc.description.abstract | The construction industry has vast potential for improving productivity and efficiency, and in the
era of Construction 4.0 the spotlight has been put on the integration of state-of-the-art digital
technologies and automation to improve productivity, efficiency, and sustainability. The use of 3D
laser scanning to collect as-built data on construction sites have been given increased attention over
the last few years, with numerous potential areas of application.
The aim of this study was to investigate how 3D laser scanning can be used to streamline the
production process of buildings. This also includes existing buildings with rehabilitation needs or
missing/lacking as-built documentation. To achieve the aforementioned aim, a scoping review and
interviews with stakeholders within the construction industry involved in the production process of
buildings were conducted. Furthermore, a small scale experiment were conducted to gain insights in
the processes of Scan-to-BIM and Scan-vs-BIM, as well as to map the necessary knowledge needed
to operate the equipment and to process collected point cloud data.
The study concludes that 3D laser scanning can be used to collect high quality as-built documentation
of existing buildings in an efficient way. Furthermore, 3D laser scanning is a crew efficient tool that
reduces the possibility of deviations, that are difficult to spot with the human eye, being overlooked,
which leads to fewer cost overruns and more flow in the production. | |
