This paper presents a geometric modelling of box girder deck to automate deck design representations. A geometric methodology was developed and implemented in a computer programme. This software allows the geometric description of the deck, using bridge design data usually given at the conceptual stage, and the automation of several drawings and(More)
This paper describes the application of virtual reality technology on the development of didactic 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(More)
Three-dimensional geometric models have been used to present architectural and engineering works, showing their final configuration. 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(More)
Normally, academic applications of computer-aided design in construction provide a visual presentation of the final state of the project and they are not able to produce changes in the geometry following the construction process. It was developed a didactic prototype that allows physical changes in a building component. This prototype illustrates the(More)
The main aim of the research project, which is in progress at the UTL, is to develop a virtual interactive model as a tool to support decision-making in the planning of construction maintenance and facilities management. The virtual model gives the capacity to allow the user to transmit, visually and interactively, information related to the components of a(More)
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. In order to obtain models, which would be able to visually simulate the construction process of two types of construction work, the research turned to the techniques of geometric(More)
The three-dimensional geometric models used to present architectural and engineering work, show only the final form, which does not allow progress in constructions to be observed. However, the visual simulation of the construction process of a building need models which are able to produce dynamic changes of its geometry. This paper reports how virtual(More)
