Abstract:
In the execution of bridge or overpass decks several construction processes are applied. A geometric model 4D (3D + time) in a Virtual Reality (VR) environment which simulates the construction of a bridge deck composed of precast beams was implemented. The model allows viewing and interaction with the various steps and the main elements involved in
the construction process. In order to develop the virtual model, the components of the construction, the steps inherent in the
process and its followup and the type and mode of operation of the required equipment were initially examined, in detail. Based on this study, the 3D geometric modelling of the different elements that make up the site was created and a schedule that would simulate an interactive mode of construction activity was established. As the model is interactive, it allows the user to have access to different stages of the construction process, thus allowing different views in time and in space throughout the development of construction work, thereby supporting understanding of this constructive method. Since the model is didactic in character it can be used to support the training of students and professionals in the field of Bridge Construction. The VR
application is currently used to support Bridge classes.
