My project is about college building .this model is done by using tekla 21.0.it is a five storey building .it can accomodate over 10000 students .it has all accomodations such as library ,sports facilities, health center, administrative and academic units. The shape and structure gives as architectural spice to the model. The stairs are done with special architectural design and are unique. Some architectural components are exported from Revit architecture using IFC format and are included in this model to add architectural spice to the structure.
