BIM-Based Data Mining Approach to Estimating Job Man-Hour Requirements in Structural Steel Fabrication

  • Author / Creator

  • In a steel fabrication shop, jobs from different clients and projects are generally processed simultaneously in order to streamline production processes, improve resource utilization, and achieve cost-effectiveness in serving multiple concurrent steel-erection sites. Reliable quantity takeoff on each job and accurate estimation of shop fabrication man-hour requirements are crucial to plan and control fabrication operations and resource allocation on the shop floor. Building information modeling (BIM) is intended to integrate multifaceted characteristics of a building facility, but finds its application in structural steel fabrication largely limited to design and drafting. This research focuses on extending BIM’s usage further to the planning and control phases in steel fabrication. Using data extracted from BIM-based models, a linear regression model is developed to provide the man-hour requirement estimate for a particular job. Actual data collected from a steel fabrication company was used to train and validate the model. Two Excel macro-enabled workbooks were also developed to provide decision-making support in fabrication planning.
