Lipman 1  \nABSTRACT  \nThe 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.  \nKEY WORDS  \nharmonization, interoperability, product model, structural steel, IFC, CIS/2 .  \nINTRODUCTION  \nA recent NIST study concluded that there was at least $15.8 billion lost in 2004 due to inadequate interoperability in the commercial, institutional, and industrial facilities industries (Gallaher et al. 2004) . Two-thirds of the costs are borne by owner-operators, which incur these costs mostly during ongoing facility operations and maintenance. During the design life-cycle phase, architects and engineers incurred almost $1 billion in interoperability costs. Of that $463 million were for the cost of manually reentering information.

Using BIM does not mean that there will be one software package that contains the entire model and that will perform all functions. Rather a construction project will require a suite of software packages that will need product models to be exchanged between them.  \nIn the steel construction industry, product models now have legal standing rather than traditional 2D drawings if not explicitly stated in the construction contract. The recently added Appendix A to the American Institute of Steel Construction’s (AISC) Code of Standard Practice states that the model shall “govern over all other forms of information, including drawings, sketches, etc.” The concrete and architecture industries are looking to the steel industry for guidanc","cbCaiqWBxgry7rsa","https://ap.wps.com/l/cbCaiqWBxgry7rsa","pdf",161863,11,"English","# Abstract\n# Keywords\n# Introduction\n# Notation and Scope\n# CIS/2 Product Model","[{\"question\":\"What are CIS/2 and IFC in the context of structural steel information exchange?\",\"answer\":\"CIS/2 is a product model and electronic data exchange format for structural steel project information.
