Many critical issues still need to be tackled properly in order to manage concurrent engineering projects effectively. These issues include versioning, notification, and propagation, all of which need to be addressed throughout the construction project lifecycle. To this end, the COMMIT project strives to achieve an improved level of support for the versioning of project information at both the conceptual (schema evolution) and the instance levels. Versioning, notification, and propagation are addressed through the CIMM (a generic and context‐independent information management model for supporting collaborative construction projects) and are described in this paper. The main concepts of the construction‐oriented COMMIT Canonical Model (CCM), specialized from the CIMM, are also presented, followed by a description of the first prototype implementation of the CIMM tackling information versioning. This research is ongoing and supported by a well‐established U.K. steering group.
