Highway Bridge Construction Process Simulation Base on 4D Visualization

It is very important that 4D visualization technology is applied in bridge construction management since traditional tools of construction management cannot present intuitive construction progress. This study established a 4D simulation model for bridge construction management by integrating the construction schedule and resource consumption progress with the bridge 3D model. Based on this model, a 4D simulation system of bridge construction was developed. With this system, a dynamic simulation of bridge construction schedule and resource requirements were realized, which make it more convenient for the users to forecast and inquire construction progress and resource consumption intensively in a visual environment. In brief, it realized visualization management and control in bridge construction. The Bridge Construction 4D Simulation System was applied in the construction management of DaWu River Bridge, a 340m pre-stressed concrete continuous rigid frame bridge.
