Abstract
Open Building Information Modelling (OpenBIM) is a collaborative project management process. Its application to road infrastructures is currently limited. OpenBIM standards for infrastructure are still under development. One of these standards is the Industry Foundation Classes (IFC), which is a data architecture for modelling infrastructure projects. The current and upcoming releases of IFCRoad focus on structuring data for the design and construction phases of an infrastructure’s lifecycle. Semantics of the O&M process phase are not fully integrated within these standards. This paper proposes an extension of the IFC schema to enrich this standard with semantics inherent in the O&M phase of road infrastructures. This extension, based on IFCInfra4OM ontology, allows the OpenBIM process to be fully applied to road infrastructures. Its implementation on a case study relative to the A7 Agadir–Marrakech Highway in Morocco enables, on the one hand, analysis and compliance with O&M management requirements on the basis of a single container: the IFC-BIM-based model. On the other hand, it allows comparison of the OpenBIM process with that of ClosedBIM for the integration of O&M data into BIM for a road infrastructure.
Highlights
While the first is characterised by using proprietary software considered as “black boxes” in terms of processes and data structure, the second allows transparent and sustainable data exchange since it is based on standards [6,7]. This is an advantage of Open Building Information Modelling (OpenBIM), because it guarantees the interoperability of data exchange between the stakeholders of a project, regardless of the software used
This paper proposes an extension of the Industry Foundation Classes (IFC) standard to allow for the management of operation and maintenance (O&M) for road infrastructures through OpenBIM
Three new object classes, that result from IFCInfra4OM ontology, are added; (2) three
