Abstract: The decrease in the quality of civil structures, due to degradations on the surface or inside caused by natural environment or external effects, is unavoidable. Therefore, maintenance management activities are important to fix and rehabilitate the degradations. In order to maintain structures, data management techniques such as IFC-Bridge models have been developed. However, they are not yet compatible with the current Industry Foundation Classes (IFC) standard. This paper focuses on the degradations that occur in harbor retaining walls and proposes adding an extension to the IFC model to host the data related to such degradations. The proposed extension uses current IFC class IfcBuildingElementProxy to represent the shape and the attribute of the civil structure and its degradations. Additionally, this paper aims to solve the interoperability issue between the new extended IFC product model and the current IFC standard in order to optimize the civil structure maintenance management. A case study has been conducted to gather information about cracks on the surface of harbor retaining walls using laser scanners and importing the gathered data to the IFC model of the harbor.
Keywords: Product model, IFC, IfcBuildingElementProxy, Degradation, Maintenance management.
