The use of HBIM and scanning in cultural heritage projects

Abstract

The adaptation of HBIM, (Historic Building Information Modelling), in cultural heritage has been a challenge since such buildings are unique. Historic buildings are known to be some of the more chal-lenging structures to rehabilitate. This has led to a backlog of digital tools in rehabilitation projects. This paper has, therefore, chosen to take a closer look at digitization and how it affects work in historic buildings. The purpose is to see to what extent HBIM has an impact on productivity in a construction process and whether this simplifies or complicates the work. A case study of the ongoing rehabilitation work at the old hospital building in Drøbak, Norway, was chosen. The shape of the building was collected by 3D laser scanning technology. The study also included qualitative in-depth interviews with a selection of involved actors. The interviewees had different roles in the rehabilitation project, which gave informative results and a broader perspective. In addition to this, a search in scientific literature was carried out in which relevant research and theories were analyzed. This method of triangulation meant that the findings could be examined and prepared further, in a methodical way.
