Simulation of mobile crane operations in 3D space

A 3D model allows users to visualize the construction process during a given period of the schedule. This paper presents a methodology to aid practitioners in preparing lift studies with crane selection, positioning, and lift optimization using a 3D space. The 3D visualization helps to identify collision free paths and optimize lifting activities based on optimal crane paths with cycle time and speed of each crane activity from simulation models in Simphony. The proposed methodology provides to help lifting engineering and project manager select the best possible crane. A case study-based approach is utilized to illustrate the proposed methodology. The case study involves construction of a four story, sixty-eight unit building for older adults in Westlock, AB, Canada. The 3D visualization model was provided for the construction team more than two months before the scheduled day of lifting, which assisted the contractor in selecting the optimum crane and successfully completing all lifts (thirty modules, 25 tons each) in just two working days.
