A formalised model of the information and materials handling activities in the construction process

A model of the information and material activities that comprise the overall construction process is presented, using the structured analysis and design technique (SADT) activity modelling methodology. The basic model is refined into a number of generic information handling activities such as the creation of new information, information search and retrieval, information distribution and person‐to‐person communication. The viewpoint could be described as that of information logistics. The model is then combined with a more traditional building process model, consisting of key phases such as design and construction. The resulting two‐dimensional matrix can be used for positioning different types of generic IT‐tools or construction‐specific applications. The model can thus provide a starting point for a discussion of the application of information and communication technology in construction and for measuring its impact on the overall process and its related cost.
