Mapping Between the CIMSteel Integration Standards and Industry Foundation Classes Product Models for Structural Steel

摘要

The CIMsteel Integration Standards (CIS/2) are the product model and electronic data exchange format for structural steel project information. CIS/2 is intended to create a seamless and integrated flow of information among all parties of the steel supply chain involved in the construction of steel framed structures. The Industry Foundation Classes (IFC) are the product model developed by the International Alliance for Interoperability to facilitate interoperability in the building industry. The recent interest in Building Information Modeling in the AEC community has shown there is a need for a mapping between the CIS/2 and IFC product models. While the CIS/2 and IFC product models have different views of modeling structural steel, a useful mapping between the two product models was developed. The mapping will permit structural steel models from CIS/2-aware design, analysis, detailing and fabrication software packages to be imported into IFC-aware software packages to do model coordination between the structural steel and the other parts of the building such as floors, walls, windows, doors, and HVAC systems. The mapping has been implemented as a CIS/2 to IFC file translator. IFC files generated from CIS/2 have successfully been imported into many IFC-aware software applications including several of the major CAD applications used in the AEC industry.
