Abstract

Building industry as one of the greatest industries in Iran comprises a significant share of waste generation in the country. Since a large quantity of the generated construction waste is buried due to the lack of a recycling protocol, it leads to an undesired waste of resources and causes severe environmental issues. This paper provides a study on the problem of material loss/construction waste in the Iranian Building Industry regarding the impact of relevant shortcomings in the stages of design, construction and supervision as the main phases of construction process. This paper includes the case studies from Isfahan, Mazandaran, Qazvin and Zanjan provinces, with a focus on the most important elements underlying construction waste generation. It also presents the experts points of view on prefab and conventional construction methods considering construction waste generation through a questionnaire-based survey. In general, the results show that Iranian project managers, engineers, contractors and workers believe that from 40 to 100 percent of construction wastes can be reduced via application of prefab construction methods. The results indicate that prefabrication can be considered as a solution to waste reduction in the Iranian Building Industry, whereas there is a dominant conventional method application in the industry.
