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.

扩展 IFC 标准以通过 OpenBIM 实现道路运营和维护管理

开放式建筑信息模型 (OpenBIM) 是一个协作项目管理过程。它在道路基础设施中的应用目前有限。基础设施的 OpenBIM 标准仍在制定中。其中一个标准是行业基础类 (IFC)，它是一种用于对基础设施项目建模的数据架构。IFCRoad 当前和即将发布的版本侧重于为基础设施生命周期的设计和施工阶段构建数据。O&M 过程阶段的语义没有完全集成到这些标准中。本文提出了对 IFC 模式的扩展，以利用道路基础设施 O&M 阶段固有的语义来丰富该标准。此扩展基于 IFCInfra4OM 本体，允许 OpenBIM 流程完全应用于道路基础设施。它在与摩洛哥 A7 阿加迪尔 - 马拉喀什高速公路相关的案例研究中的实施，一方面能够基于单个容器：基于 IFC-BIM 的模型分析和遵守 O&M 管理要求。另一方面，它允许将 OpenBIM 过程与 ClosedBIM 的过程进行比较，以便将 O&M 数据集成到道路基础设施的 BIM 中。
