Using Effort Distribution Analysis to Evaluate the Performance of Building Information Modeling Process

摘要

Adopters of BIM need to find the most appropriate implementation strategy that is economically efficient for their organization in order to achieve satisfactory organizational and project outcomes. This paper explores why and how the distribution of effort spent on various project activities over a project's life cycle can be used at both project and organizational levels as one of the metrics for evaluating, benchmarking and improving the performance of BIM implementation process. Using a case study, it explores how project time accounting data can be used to visualize and analyze effort distribution pattern. The findings shows the benefit of BIM effort distribution. Based on the visualization, unusual distribution of efforts can be identified and organizations can understand the productivity of their processes. The unusual effort distribution alert can support root-cause analysis process to identify and correct the root causes. On that basis, corrective and preventive actions can be implemented, and BIM process can be improved. The analysis of effort distribution can also help organizations compare BIM projects with non-BIM projects. It can be used to manage cash flow, and to structure fees and support return on investment analysis. Effort distribution analysis can increase project participants' understanding of project dynamics from a resource allocation perspective.
