The bridge swivel construction method is invented mainly for solving the problem that fine management of bridge swivel site construction is difficult at present. The comprehensive management comprises the steps of viewing the scene of the electronic sand table and combining the comprehensive management with the three-dimensional visualization technology. The technical management comprises the steps of checking the scene of the electronic sand table, intersecting the background by a three-dimensional visualization technology and checking collision. And the progress management compares and analyzes the actual progress and the planned progress according to the compiled construction progress plan, and automatically calculates the delay period. And the cost management directly counts the quantity of the generated projects by using the built model. And safety management monitors the swivel beam support, establishes association between the BIM and the equipment and forms an information base for safety quality management. The method has the advantages of assisting managers in effective decision making and fine management and ensuring that management elements such as construction plans, progress, quality and the like can be managed and controlled.
