The International Alliance for Interoperability (IAI) is a non-profit alliance of the building industry including: architects, engineers, contractors, building owners and facility managers, building project manufacturers, software vendors, information providers, government agencies, research labs and universities. Currently, there are 9 member chapters in Australasia, French speaking, German speaking, Japan, Nordic countries, North America, Singapore, South Korea, and the United Kingdom.

Its mission is to integrate the AEC/FM industry by specifying Industry Foundation Classes (IFC) as a universal language to improve the communication, productivity, delivery time, cost, and quality throughout the design, construction, operation and maintenance life cycle of buildings.

The Alliance is committed to taking advantage of the collective power of the industry to produce a standard for communication which will propel it into the future promoting collaborative efforts and global expansion.
