Network models with both time and cost dimensions have not been used extensively on industrial construction projects. Analysis of 33 companies participating in the study revealed that network model requirements were incompatible with information currently generated by the organization. Moreover, the organizational structure of a company was a strong determinant as to the level of model sophistication adopted. For example, companies with decentralized estimating and scheduling used bar charts and simple time-based models. Incompatibility of model inputs requirements and available data was not a problem since the source and use of such information was at the same point in the structure.
