- 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.
