“…The Cultural Heritage Object is somewhat more ambiguous: the objects could be of type Heritage Building, Cultural Landscape, Urban Heritage (multiple buildings) or Technical heritage (e.g., a bridge). In IFC4.3 these objects could be classified in the IfcFacility class [57]. However, as this class is not yet available in IFC4, we consider the IfcBuilding class to be the most appropriate.…”

Cultural heritage building information models (HBIMs) incorporate specific geometric and semantic data that are mandatory for supporting the workflows and decision making during a heritage study. The Industry Foundation Classes (IFC) open data exchange standard can be used to migrate these data between different software solutions as an openBIM approach, and has the potential to mitigate data loss. Specific data-exchange scenarios can be supported by firstly developing an Information Delivery Manual (IDM) and subsequently filtering portions of the IFC schema and producing a specialized Model View Definition (MVD). This paper showcases the creation of a specialized IDM for the heritage domain in consultation with experts in the restoration and preservation of built heritage. The IDM was then translated into a pilot MVD for heritage. We tested our developments on an HBIM case study, where a historic building was semantically enriched with information about the case study’s conservation plan and then checked against the specified IDM requirements using the developed MVD. We concluded that the creation of an IDM and then the MVD for the heritage domain are achievable and will bring us one step closer to BIM standardisation in the field of digitised cultural buildings.

The Architecture, Engineering and Construction (AEC) is in its transition from 2D design processes to 3D object-oriented modelling. Building Information Modeling (BIM) is steadily gaining importance, replacing the conventional Computer-Aided Design (CAD) practices and getting implemented in every aspect of the very complex software and stakeholder landscape (Jaud et al., 2019). As one of the main principles, BIM describes the idea of integrating all information relevant to the life cycle of a structure, such as a tunnel, bridge, building or road, in a digital (BIM) model. The digital model is to ensure, among other things (Amann, 2018):• that all relevant data is available to all project participants; • that all data is in a consistent state (data integrity should be guaranteed); and • that the data can be used efficiently. TUM Open Infra Platform (OIP) is an open source application for viewing and analysis of different BIM models used in the civil engineering field. OIP supports reading, visualization, navigating, and handling of:

The open data exchange standard Industry Foundation Classes (IFC) has been recently significantly extended to also cover infrastructure facilities such as roads and railways. The results of these activities form part of version 4.3 of the standard. Linear placement of objects is one of the most important concepts in infrastructure asset modelling. As such, Release Candidate 1 of IFC 4.3 has been critically analysed. In this paper, we address several issues that were identified together with the participants of the IFC Infrastructure Extension Deployment and IFC Rail Phase 2 projects. We present an improved model removing unnecessary doubling of concepts and reusing many already established entities. We showcase the new model on two example scenarios from one of the projects and determine better adherence with the IFC legacy. The proposed improvements have been adopted in Release Candidate 2 of the IFC 4.3.
