Sreram, P K and Thomas, A (2021) A framework for identification of critical material waste causes during construction using DEMATEL and social network analysis. In: Scott, L and Neilson, C J (eds.) Proceedings of 37th Annual ARCOM Conference, 6-7 September 2021, Online Event, UK.
Abstract
The construction sector is the second major contributor to India's gross domestic product with the consumption of natural resources such as sand, aggregate, and lime. Along with the consumption of these resources, material waste also occurs during a construction project with its knock-on effect on cost and other detrimental effects on the environment. Understanding various factors causing material waste and the inter relationships would help the construction industry to alleviate the detrimental effects of such causes on sustainable construction. While the literature review has provided the reasons for the material waste, limited research is available on investigating the interrelations between the contributing factors. Therefore, an integrated framework consisting of construction site specific questionnaire survey, decision-making trial and evaluation laboratory (DEMATEL) and social network analysis (SNA) is proposed to identify the critical causes of material waste and its inter relationships. The results have indicated that 55 out of 110 interrelations are important. Further, tendering errors and design errors are the critical causes of material waste, and human errors are central within the network of critical interrelations.

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
