Page 3 - The visual simulation of the construction process needs to be able to produce changes to the geometry of the project dynamically. It is then important to extend the usefulness of design information to the construction planning and construction phases. The integration of geometrical representations of the building together with scheduling data is the basis of 4D (3D + time) models in construction domain. 4D models combine 3D models with the project timeline [2].
