The development of the IFC 4.3 candidate standard sets the pathway for interoperability amongst different infrastructures that have been harmonized under the buildingSMART project proposals. Furthermore, the use of laser scanning as a tool for the monitoring of infrastructures has also been rising. This paper showcases a combination of BIM and remote sensing for infrastructure in a road scenario. A semi-automatic approach is presented for the IFC 4.1 compliant modelling of traffic signs and guardrails, along with the inclusion of some semantics via property sets. The input data for the IFC modelling procedure is obtained from the automatic processing of a 3D point cloud, that extracts road alignment, traffic signs, and guardrails, and from standardized dimensions for certain assets. The point cloud processing is validated for the guardrail identification and the IFC modelling is described alongside an UML, exemplifying the possibility of modelling the as-is state of the road infrastructure.

IFC 4.3候选标准的制定为在buildingSMART项目建议下已协调的不同基础架构之间的互操作性设置了途径。此外，激光扫描作为监视基础设施的工具的使用也在增加。本文展示了BIM和遥感技术在道路场景中的结合。提出了一种半自动方法，用于对符合IFC 4.1的交通标志和护栏建模，以及通过属性集包含一些语义。IFC建模过程的输入数据是从3D点云的自动处理中获得的，该3D点云提取了道路路线，交通标志和护栏，并从某些资产的标准尺寸中提取了数据。
