Bim parametric modelling of a railway underpass [Modellazione parametrica in ambiente bim di un sottovia ferroviario]

Building Information Models allow designers to achieve greater efficiency among various design alternatives and to derive the optimal solution. Building Information Models contain the data necessary not only for design, but also to support bidding, construction, and subsequently maintenance and management of the operation of the building or infrastructure. This research involved exploring the concept of parametric Building Information Modelling, also known as generative design or algorithmic design, based upon a “reverse engineering” approach applied to a railway underpass in the north-eastern part of Slovenia. Under the BIM approach, international standards are applied wherever possible (e.g., Industry Foundation Classes-IFC, classification system, model naming conventions)
