An Information Reference Model for Architecture, Engineering, and Construction

This paper describes the results of the information modelling work group from the International Workshop on Models For Computer-Integrated Construction in Finland, October 1992. At this workshop, researchers from around the world presented their individual modelling efforts. These models’ parallel goals and abundant similarities led the participants to combine their individual results into a single cohesive reference point to act as a basis for future work. The result is IRMA, an Information Reference Model for Architecture, Engineering, and Construction. IRMA can serve as the core of a conceptual project model, which can be used as a framework for data standards, as a kernel for modelling, and as a basis for implementing computer applications. It defines generally applicable relationships between products, activities, resources, and participants in a building project.
