Construction Operations Building Information Exchange (COBie) is an international standard relating to managed asset information including space and equipment. It is closely associated with building information modeling (BIM) approaches to design, construction and management of built assets, and was devised by Bill East of the United States Army Corps of Engineers, who authored a pilot standard in June 2007.[1]

COBie helps capture and record important project data at the point of origin, including equipment lists, product data sheets, warranties, spare parts lists, and preventive maintenance schedules. This information is essential to support operations, maintenance and asset management once the built asset is in service.[2]

In December 2011, it was approved by the US-based National Institute of Building Sciences as part of its National Building Information Model (NBIMS-US) standard.[3]

COBie has been incorporated into software for planning, design, construction, commissioning, operations, maintenance, and asset management. COBie may take several approved formats include spreadsheet, STEP-Part 21 (also called IFC file format), and ifcXML. In early 2013 BuildingSMART was working on a lightweight XML format for COBie, COBieLite, which became available for review in April 2013.[4]

In September 2014, a code of practice regarding COBie was issued as a British Standard: "BS 1192-4:2014 Collaborative production of information Part 4: Fulfilling employer’s information exchange requirements using COBie – Code of practice".[5]
