As part of the Danish Classification Project a report describing the information flow in a traditional building project has been published. By defining the final product as the building as well as the documentation, the value chain throughout the different phases of a Construction project is identified. Between the design and Construction phase the value-perception changes from adding value to the documentation to adding value to the physical Construction. To reduce the amount of work converting the documentation to the exact information, the contractor needs to carry out each activity; a classification hierarchy based on the ISO 12006-2 standard is currently being defined. The hierarchy is being developed in preparation for introducing an object-oriented datastructure with ”Work Result” as a common object for carrying information throughout the building lifecycle. ”Work Result” is the outcome of the activities (the transformation of resources) in the Weekly Work Plan used in the Last Planner System. At the same time the ”Work Result” object is the link to integration between object oriented product models and process models, in this case the three levels of planning proposed in the Last Planner System.


Value chain, documentation, information flow, objects oriented, classification, and strategies of implementation.
