Krane CEO, Eshan featured in assessing productivity on Webcor Transbay Block 8 Project

Lean aims to maximise value while minimising waste. Hence, it is essential to use Lean tools and techniques for achieving higher value in construction projects. Being one of the Lean techniques, time studies are of utmost importance in terms of measuring productivity and construction project success. This paper aims to assess the use and effectiveness of time studies in Lean construction projects along with a case study. According to the case study analysis, it is observed time studies are effective techniques to identify value and non-value-adding activities. The study also indicates that it is critical to conduct time studies for implementing proper Lean strategies. Time study is not a direct tool to improve processes; however, it is an irreplaceable indicator, which helps identify waste and select best strategies accordingly. Hence, the main contribution of this study is to highlight the important role of time studies in terms of providing a roadmap for identifying waste and increasing productivity accordingly. Besides, a framework and strategies with respect to waste types are proposed to promote the use of time studies. The study is expected to encourage construction professionals in terms of utilising Lean practices and specifically time studies in their projects.
