Design For Waste Reduction And Efficiency Improvement For The Construction Usage Of The Tower Crane, George Merida, Roman Richard

Industrial and Manufacturing Engineering

Webcor Concrete Group’s on-site tower crane is currently experiencing unknown forms of inefficiency. The project team used the DMAIC methodology to implement Define, Measure, Analyze, Improve, and Control in order to guide and structure the project. After the project team formulated a problem statement, observations were collected of tower crane deliveries resulting in 470 individual data points. The data was then analyzed using basic statistics, histograms, and lean manufacturing tools in order to identify wastes and inefficiencies. Once the wastes and inefficiencies were identified, root cause analysis was performed. The identified root causes were then used as the basis for …
