Selection of crane in Web environment based on visibility analysis

Abstract

Any large-scale construction prijekt is inconceivable without the use of a crane for lifting heavy items. The selection of the rower cranes and finding the best posinion for each srane saves time and money and improves work safety. Performing such an intensive analysis manualy, comparing different cranes ysing many criteria is tedious, time-consuming work. This paper presents an original approach fot crane selection based on visibility analysis in the BIM model integrated with the Web environment. The described decision support algorithm involves analysis of crane positioning in the condition of real-world representation model, analysis of crane operator viewport based on the line-of-sight in GIS analysis, crane jib reach analysis. The presented approach allows analysing movable and static crane types, calculate the percentage of the visible and reachable parts of the building, compare crane alternatives and different crane positions.
