construction processes%process modeling%subsequent modifications
This paper presents an approach to handle different types of subsequent modifications in con-struction processes. It is focused on a formalized approach with the objective that effects of subsequent modifications are detected automatically. The approach presented in this paper makes use of an existing modeling technique specifically focused on construction processes. The modeling techniques result in a process description where all technological interdependencies between construction activities are consid-ered and where consistency between the sequence of activities and the history of components is guaran-teed. This modeling technique is expanded by an existing concept for handling versions and dependencies between objects. The integration of these different concepts makes it possible to track effects of relevant types of subsequent modifications in construction processes on a formalized basis. Effects of subsequent modifications are detected by algorithms, different versions can be compared by algorithms and different versions are stored so that subsequent modifications are documented. The innovation of the approach pre-sented is the completeness. Effects of different relevant types of subsequent modifications in construction processes are tracked on a formalized basis.
