Virtual environment in Civil Engineering education : Construction of a wall , a bridge and a roof

This paper describes the application of virtual reality technology to the development of teaching models related to the construction activity and to the design of roofs. The models, showing construction processes, allow the visualization of the physical progression of the work following a planned construction sequence, the observation of details of the form of every component of the works and carry the study of the type and method of operation of the equipment applied in the construction. The roof model supports student to draw up plan drawings of roofs and the correspondent 3D model, tasks which relies on an understanding of the three-dimensional nature of the respective constructive process. The models present distinct advantage as educational aids in first-degree courses in Civil Engineering. The main objective of the practical application of the models is to support class-based learning and in addition, the students can interact with the models using there own PC. The models are adequate to be used in distance training based on e-learning platform technology. The involvement of virtual reality techniques in the development of educational applications brings new perspectives to Engineering education.
