Based on a synthesis of several change process models reviewed in the literature and the characteristics of
computational environments, a generic change process model is proposed having five stages in a sequence:
identify, evaluate & propose, approve, implement and review. Building an effective construction change
management system is very challenging, and one can hardly find a mature software tool on the market, that
deals with this issue. Existing change management module, that some software claimed to have, is mostly a
feature for change information recording and document approval. Change estimation, impact analysis, postchange analysis, statistics, and more importantly, change traceability are lacking in these solutions. An
integrated change management system requires technical supports from different technologies, including
collaborative workflow, system integration and collaboration technologies, nD modeling, web-based
collaborative project management tools, and online document management tools. We have not arrived at a full
solution for construction change management yet. More work will have to be undertaken to develop
innovative and practical solutions that are adoptable by the industry.
