Unnikrishnan, S and Sudhakumar, J (2025) Identification of wastes and its causes in Indian construction industry based on lean construction practices. International Journal of Construction Management, 25(5), pp. 562-571. ISSN 1562-3599
Abstract
This manuscript proposes lean construction (LC) methods in construction projects to reduce non-value-added activities or wastes, improve communication and raise team effort. The optimization hybrid approach is golden jackal optimization. The key objectives are to identify distinct non-value-added activities as well as the fundamental causes of each waste. Construction managers were interviewed, and it was determined that they were completely unaware of LC principles. A questionnaire survey is used to determine the respondents' overall understanding of lean building practices, numerous wastes in the construction industry, underlying reasons of every waste. The obstacles were identified by an existing literature research and then defined among several professional groups. It concluded that reducing the obstacles will result in less waste, as well as increased efficiency and productivity in the building industry. The proposed approach is utilized for predicting the wastes based on LC. The performance of the proposed technique is implemented in MATLAB and compared with existing techniques.

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
