Industrial Engineering/Manufacturing Techniques for Enhancing Construction Project Performance

Previous research isolated five significant factors contributing to non-value adding (NVA) activities. (RS265-1, p. 3)

1. Incorrect materials
2. Inadequate equipment
3. Lack of appropriate tools
4. Absence of information
5. Insufficiently qualified personnel

RT-265 created a table of possible IE solutions that could resolve challenges often faced on a project site. Samples of these techniques are shown in the table below. (RS265-1, p. 8)

RT-265 took advantage of the “Five Whys” process to identify root causes of common project challenges. This process was utilized to determine which of the standard IE techniques could possibly resolve the challenges. (RS265-1, p. 12)

Part of the implementation tool developed by the RT was flowcharts. These flowcharts are utilized in the quick identification of project site challenges. The charts are a visual flow based on the team’s “Five Whys” process. (RS265-1, p. 13)

There is a return for implementing IE techniques to eliminate NVA. However, RT-265 determined that the ROI of implementing IE techniques couldn’t be determined on a process or project wide basis. The ROI is unique to each application and its many variables and site exclusive challenges. The best approach may be for each company to create their own hypothetical example using predetermined constants. In the "big picture," RT-265 would indicate very minimal costs to implement this type of program; therefore benefits result in a priceless return.

RS265-1, IE Techniques for Construction Jobsites

Shows the benefits of using 22 IE techniques to improve jobsite problems. (RS265-1, Appendix, p. 31)
