CAD2 is a subject related with BIM technology and is connected with using information incorporated in the models of the designed buildings. Project stage and the stage of construction require numerous corrections and alterations of introduced data and geometry of particular elements. Adequate support offered by software and appropriate use of maturity levels in BIM technology allows the designer for fast coordination and information management in the 3D model which is especially useful in the context of public tender commissions and designer’s supervision throughout the construction stage. With adequate support of designing software, BIM technology is becoming a powerful tool which allows fast coordination while changing data and information in the modelled object in order to avoid design conflicts.
