Abstract
BIM (Building Information Modeling) is a new concept in construction industry and becomes popular worldwide in recent years. BIM is widely used by individuals, businesses and government agencies. It is applied in all phases of construction lifecycle from planning and designing to constructing and maintaining. It contains different structure types of buildings and infrastructures including water, refuse, electricity, gas, communication utilities, roads, railways, bridges, ports and tunnels. The application of BIM in the building industry is relatively widespread while the development of BIM method in the domain of infrastructure is yet in infancy. In this research, we would like to study the compatibility of BIM in modeling the bridge by using Autodesk Revit.
In this chapter, two data exchanging open standards that are mostly used in BIM, in the field of bridge modeling, including IFC (Industry Foundation Classes) and CityGML (Geography Markup Language) are reviewed. A parametric 3D bridge model is established with Autodesk Revit in order to carry out an experiment on bridge information modeling. The Raymond Barre Bridge in Lyon, France is used as case study.
We have divided the process of modeling the bridge to two steps. The first step is structuring the bridge elements, which means to generate the different parts of the bridge including the foundations, deck parts, diaphragms and bowstring; and the next step is to assemble the deck parts and placement of bridge elements. In the modeling process, a large number of customer families are created to represent the missing bridge entities that could result in the information loss in IFC file.
We show that the current IFC is not well developed for bridges and it is needed to define specific entities dedicated to the bridge domain. We also refer to the other research in this domain and their suggestions for extending IFC for bridges such as bridge data dictionary, information delivery manual, missing concepts and new entities for IFC-bridge. The results identify the urgency to improve IFC for infrastructure domain, especially for the IFC-Bridge.
