Digitalization for safer restoration practices of industrial buildings using building information modelling (BIM): A review and a case study for gasometers

The refurbishment of industrial heritage structures offers economic benefits and provides future generations with an insight into the industrial history of cities. Industrial heritage projects possess unique attributes and risks, and the procedures for restoring, renovating, and converting these structures differ from those of other construction projects. The study introduces the concept of prevention through design into the BIM model for each element by adding an eighth dimension. Two gasometer projects were analysed as a case study. A team of experts was utilised to identify potential health and safety hazards and risks connected with both construction and post-commissioning operations. This information was then incorporated into the BIM model and safer design proposals, along with necessary safety measures, were embedded in the LOD of each element. This study proposes a method for engaging safety professionals, restoration experts, and site managers in the early design decisions of industrial heritage projects.
