Abstract. Precise and detailed information for infrastructure assets, as well as information about the property interests attached to them are crucial to prevent unnecessary costs, disruptions, and delays when planning, constructing, and managing such objects. Various models encapsulating infrastructure objects information are available, mostly during their design stage, and could be also reused in other stages of the Spatial Development Lifecycle (SDL), such as the Land Registration. In this respect, and as ISO 19152:2012 Land Administration Domain Model is currently under revision, it is well-timed to consider the modelling of infrastructure objects within the scope of the upcoming Edition II of the standard. Given this background, the aim of this paper is to initiate the discussion on the registration options of infrastructure objects in the context of the LADM revision. Attention is given on specific categories of transport infrastructure objects, identifying the information required to be reused in other stages of the SDL, sourced from BIM/ IFC files used in the design stage. As currently IFC does not support infrastructure information, in order to investigate how such information is stored in IFC models based on the modellers’ decisions and the software used, two models of transport infrastructure objects coming from the industry were inspected and based on these findings, the conceptual modelling followed, based on the LADM concept. The paper aims to provide insights on to the limitations of the current use of IFC for transport infrastructure objects and propose the future steps to overcome them.
