The methodology is tested on a case study in order to illustrate its effectiveness. Modular-based heavy industrial projects, which involve a large number of lifts on congested and/or dynamic site layouts, require not only the design and selection of efficient mobile crane operations, but also rapid and accurate responses to design changes in the planning stage of the project to ensure successful project completion. Existing tools have not yielded strategies which support informed decisions to select the most suitable mobile crane operation (e.g., the cycle time of the crane lift) among several alternatives. This research develops a 3D-based crane evaluation system (3D-CES) which designs, verifies, and simulates 3D visualization of mobile crane operation not only to support the selection of the most efficient crane operation, but also to plan the crane lift schedule during crane lift studies based on identification of safety and productivity aspects. These aspects are shown to increase efficiency, timeliness, and profitability of construction through effective collaboration and communication.
