Title: BIM Log Mining: An Application of Data Science and Social Network Analysis in Design Productivity Assessment
Abstract:
A new data mining approach is presented to measure design productivity and collaboration. Instead of relying on manual collection of data and non-verifiable presumptions about design process, the new approach capitalizes on large volumes of data available in the event logs of computer programs used by designers in developing building information modeling (BIM) models. Event log files are used as a cost-effective source of productivity data to create new process mining algorithms for identifying fundamental attributes describing individual designers’ patterns in the execution of design tasks. Empirically-verifiable links are explored between design productivity and the electronic traces that designers have left behind, while taking into account unique characteristics of the project and distinctive attributes of the collaborative design team. It is shown that the identified patterns in the execution of design commands along with the quantified characteristics of design collaboration network have significant effects on explaining and predicting the variability in design productivity. The data mining assessment tool can assist BIM project managers to:
1) Estimate time and resources needs to complete design tasks;
2) Monitor design progress and control design quality; and
3) Determine the most desirable configurations of the design team considering the unique features of the project.
