The use of Building Information Models (BIM) for design and construction processes are growing as a whole, especially in terms of mobility platforms that help with managing the construction process. One area, however, that is lagging in the use of BIM for automated or semi-automated processes such as estimating. Literature has explored some reasons for this lack of adoption of BIM for estimating as issues with the user trusting the model’s accuracy when that model is created by someone else when using a federated model approach. In order to enhance user confidence of BIM results with automated processes two areas were examined: (1) the use of historic data to create a reliability model based on risk and financial impact of systems and (2) examining factors of project delivery that influence the use of BIM. This paper discusses a two part survey that examined the project delivery system and various other factors as to how they relate to the user’s confidence in the accuracy of a model. Results indicate that personal relationships are more influential than contractual obligations. Finally, findings of the survey that identify common trends of respondents in terms of setting up a project delivery to maximize the utilization of BIM are included.
