3D and VR models in Civil Engineering education: Construction, rehabilitation and maintenance

Where educational validity is concerned, a school of engineering can reasonably be expected to constantly update computational resources in frequent use in the professions. Virtual reality (VR) technology could be applied as a complement to three-dimensional (3D) modelling, leading to better communication whether in vocational training, in education or in professional practice. Techniques of 3D modelling and VR were applied to the development of models related to the construction process. The 3D models created to support rehabilitation design emerge as an important tool for the monitoring of anomalies in structures and to assist decisions based on the visual analyses of alternative solutions. The VR model created to help the management of lighting systems in buildings allows the visual and interactive transmission of information related to the physical behaviour of the elements, defined as a function of the time variable. Didactic interactive models showing construction works were also developed. These applications allow the visual simulation of the physical progression of each type of work and also assist in the study of the necessary equipment needed and how it functions on site. The introduction of CAD and VR techniques in school is helpful to students in order to prepare them to consider these technologies as important supports, later in their professional practice.
