BuildingSmart International has published IFC 4.3 as a production standard, which means it is ready for use and for vendors to implement.
The IFC 4.3 programme extends the IFC benefits for horizontal assets, ie infrastructure that stretches across the landscape such as roads and railways and all their associated features. The full scope includes road, railway, ports and waterways, bridges, and the common elements between all these.
The first phase of the projects within the programme defined the IFC entities for use cases, including alignment reference, aggregate structures, earthworks, bridge structural, rail power, rail signalling, rail track, rail telecoms, drainage, maritime elements, and some geotechnics.
The second phase of these projects produced test instructions and delivered software validation of the IFC 4.3 standard. This phase also included the definition of the three base implementation levels: the Reference View, the Alignment Based Reference View, and the Design Transfer View.
