Abstract
Construction projects result in the generation of wastes, which can be broadly classified into physical and non-physical wastes. Non-physical wastes present a different challenge than physical waste due to their intangible nature. This study focuses on understanding the importance of the classical Lean Construction (LC) wastes and their degree of influence on the Transformation-Flow-Value (TFV) aspects of construction projects using empirical data. A structured questionnaire was designed and completed by 60 participants from the public and private sectors in Nigeria and analyzed using the Relative Importance Index (RII). The statistical analysis indicated that 'Making-Do' is the most critical non-physical waste during the transformation process of construction, followed closely by 'Non-Utilized Talent'. 'Waiting' and 'Transportation' are the two most essential aspects in the flow aspect of construction, while 'Overproduction' is the most crucial waste category affecting the value aspect of construction. The findings of this study can be used for improving the productivity of construction projects by focusing on techniques to reduce the most critical non-physical wastes.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
