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.

It was developed a didactic prototype that allows the visualization of the physical changes of the construction of a common external wall. In order to obtain models, which would be able to visually simulate the geometric evolution of the construction activity, techniques of geometric modeling and virtual reality were used. The visualization of the distinct physical steps of a construction is shown as 3D models following a specific planned schedule. The model makes it possible to view the physical evolution of the work, to follow the planned construction sequence and to visualize details of the form of every component of the works. It can be manipulated interactively allowing the student/teacher to monitor the physical evolution of the work and the construction activities inherent in its progression. The developed model brings new perspectives in the teaching activity as a support to expose new curricular programs or complex sequence construction.

But, when the clarification of a detail or the constitution of a construction step in needed, these models are not appropriate because they do not allow the observation of the construction activity. Models that could present dynamically changes of the building geometry are a good support on education in civil engineering domain. Techniques of geometric modelling and virtual reality were used to obtain interactive models that could visually simulate the construction activity. The applications explain the construction work of a cavity wall and a bridge. The models present distinct advantage as educational aids in first-degree courses in Civil Engineering. The use of Virtual Reality techniques in the development of educational applications brings new perspectives to the teaching of subjects related to the field of civil construction.

But, the visual simulation of the construction process of a building need models which are able to produce dynamic changes to their geometry. This paper reports how techniques of geometric modelling and virtual reality were used to obtain models that could show their physical evolution over time and which would be able to simulate construction processes visually. Two types of work, concerning the construction of a cavity wall and a bridge, were developed as virtual models for educational purposes. These models make it possible to view the physical evolution of the work, to follow the planned construction sequence, to visualize details of the form of every component of each work and to support the study of the type and method of operation of the equipment necessary in the construction process. These models have been used to distinct advantage as educational aids in first-degree courses in Civil Engineering. The use of virtual reality techniques in the development of educational applications brings new perspectives to the teaching of subjects related to the field of construction.

A aplicação desenvolvida corresponde ao modelo de uma parede dupla de alvenaria, uma das componentes de uma construção corrente. De modo a poder simularse visualmente a construção da parede, o modelo geométrico gerado é composto por um conjunto de elementos representando cada um uma componente construtiva. Por recurso a um sistema virtual, são aplicadas sobre o modelo da parede propriedades especÃficas próprias de um ambiente de simulação virtual. Por interacção directamente com o modelo, é possÃvel controlar a progressão do processo construtivo da parede e aceder a informação relativa a cada elemento, nomeadamente, a sua composição e a fase da sua execução ou montagem em obra, de acordo com determinado planeamento. Demonstra-se, com este exemplo, como a tecnologia de realidade virtual pode ser vantajosamente utilizada na elaboração de material didáctico de grande interesse na formação na área de processos construtivos. Palavras-chave Novas tecnologias de ensino, realidade virtual, simulação visual de processos construtivos.

O modelo geométrico do tabuleiro da ponte foi criado através de um sistema de modelação de tabuleiros de pontes implementado no âmbito de um projecto d! investigação no ICISTIDEC . Na programação da simulação visual da actividade de construção da ponte foi utilizado o sistema de realidade virtual EON Studio. A aplicação prática do modelo virtual da construção de uma ponte tem como alvo a formação em processos construtivos num ensino presencial e numa formação à distância apoiada em tecnologia e-learning.

It was developed a didactic prototype that allows physical changes in a building component. This prototype illustrates the construction of a common external wall. First, a 3D geometric model composed with the several elements needed to construct it was defined and, then, virtual reality capacities were applied over it. The virtual model allows students to interact with it visualising the sequence of the construction process, accessing to quantitative and qualitative information of each construction stage, observing the configuration details of the building components and how they connect together. The didactic application contributes to support disciplines concerning with Civil Engineering.

In order to obtain models, which would be able to visually simulate the construction process of two types of construction work, the re- search turned to the techniques of geometric modeling and virtual reality.

In the present study, two engineering construction work models were created, from which it was possible to obtain three-dimensional models corresponding to different states of their form, simulating distinct stages in their construction. The use of techniques of virtual reality in the development of these educational applications brings new perspectives to the teaching of subjects in the area of civil engineering.

Current computer tools and models are not able to follow changes in the geometry of a building or structure during the construction process. A Virtual Reality technology application in the construction-training domain is described. A prototype was developed. It serves as a didactic tool for civil engineering students of disciplines concerned with building's construction. Geometric Modelling and Virtual Reality techniques are used on the visual simulation of construction processes and to define user-friendly interfaces in order to access construction information, which could prove useful to civil engineering professionals. The construction of a double brick wall is the case studied. The wall is defined as a 3D geometric model formed with the several components needed to construct it. Using the wall's virtual model it is possible to show, in an interactive way, the sequence of the construction process and observe, from any point of view, the configurations in detail of the building components. This is a didactic application in the construction processes domain of great interest to civil engineering students. So, using the developed virtual model, allows students to learn about construction planning of a specific situation in the space provided by the virtual environment. This communication is then oriented to teaching construction techniques by means of virtual environments. It is expected that the implementation of the prototype will be able to contribute to support teaching disciplines concerned with Civil Engineering. Another objective in creating these kind of virtual applications is to show in which way new technologies afford fresh perspectives for the development of new tools in the training of construction processes.
