Ongoing projects
buildingSMART is committed to enhance its standards to enable standardized infrastructure asset data management throughout the life cycle of the facility.
A comprehensive neutral data schema capable to present semantic and geometric aspects is necessary to enable data exchange and open access in the context of planning, realization and maintenance of road, rail, bridge, tunnel and other linear infrastructure works.
ongoing infrastructure projects
In order to achieve its mission the Infrastructure Room of buildingSMART carries out the following standardization projects:
Extensions of the IFC (ISO16739) data standard:
IFC-Alignment NEW! bSI Candidate Standard (open for review now) IFC-Bridge IFC-Road
Other standardisation work:
InfraModel (enhancement of LandXML)
IFC Alignment
The first buildingSMART IFC for Infrastructure extension project is the P6 "IFC Alignment" project. It will act as a baseline for further projects, such as IFC-Bridge and IFC-Road, and provides the data model for 3D and 2D alignment information for spatial location of infrastructure assets.
Status: bSI Final Standard Overview presentation
development goals
Main achievements of the IFC Alignment 1.0 are:
Ability to exchange alignment information from planning to design, to construction, and finally to asset management phase Ability to link alignment information to other project information such as cross sections and full 3D geometry of construction elements (realized by upcoming IFC-Bridge and IFC-Road projects) Ability to query alignment information providing data such as linear referencing for positioning Ability to allow open data access of alignment information from asset management databases Ability to map IFC alignment models to InfraGML (developed by OGC), and LandXML (latest InfraBIM version from buildingSMART Finland)
Official documentations
The buildingSMART P6 IFC-Alignment project developed the specification to enhance the current IFC4 (ISO 16739) data standard, including process definition, exchange requirements, data model, and model view definition with samples.
In July 2015, the IFC Alignment 1.0 has been accepted as a buildingSMART Final Standard.
The following documents are published:
Exchange Scenarios [informative] Conceptual Model [normative] IFC Extension Summary [informative] IFC Model View Definition [normative]
Cooperation
nternal: There is a strong collaboration within the buildingSMART Infrastructure Room and upcoming projects on IFC-Bridge and IFC-Road to use the alignment schema for upcoming infrastructure standards.
External: The work on the IFC Alignment Extension has been carried out by the P6 project team in strong collaboration with OGC LandInfra Group. The use cases and the conceptual model are results of the joint work.

IFC Alignment 1.0
Documents published for the public review of the IFC Alignment 1.0 standard. All comments are listed in the IFC4 issue database.
Status: bSI Candidate Standard The IFC Alignment 1.0 standard is currently in the final approval stage by buildingSMART.
- public review
The public review process of the IFC Alignment buildingSMART Candidate Standard was open from January 26th to March 6th, 2015. Based on the results of the public review the IFC Alignment Schema has been presented and reviewed at the buildingSMART International Summit, March 23-25, 2015 in Watford, UK. A resolution has been passed to initiate the process of final acceptance as a buildingSMART Final Standard.
These documents for the "IFC Alignment Extension" candidate standard are available for review:
IFC-Alignment Exchange Scenarios (with use cases and process maps) IFC-Alignment Conceptual Model (UML Schema and documentation, joint work with OGC) IFC-Alignment IFC Extension Summary (applying the conceptual model to IFC4 Standard) IFC-Alignment IFC Model View Definition (including EXPRESS + XSD Schema and example data sets)
All feedback has been logged into the IFC issue database.
