ISO 29481-2:2012 specifies a methodology and format for describing ?coordination acts' between actors in a building construction project during all life cycle stages.

It therefore specifies

• a methodology that describes an interaction framework,
• an appropriate way to map responsibilities and interactions that provides a process context for information flow,
• a format in which the interaction framework should be specified.

ISO 29481-2:2012 is intended to facilitate interoperability between software applications used in the construction process, to promote digital collaboration between actors in the building construction process, and to provide a basis for accurate, reliable, repeatable, and high-quality information exchange.
