The construction industry consumes a huge quantity of raw materials, some of which ends up as waste in the construction process. Among many factors, studies suggest that the inexperience of labour is one factor that generates construction material waste. However, an in-depth analysis of construction material waste generation concerning the different levels of labour experience has not been undertaken. Thus, this study investigates the influence of labour experience in the generation of brick and tile material waste in the Sri Lankan construction industry and, thereby, develops a model to predict average waste generation with respect to labour experience. Bricks and tiles were considered since they are identified as the materials most wasted in the Sri Lankan construction industry. To carry out this research, nine similar commercial projects under construction using bricks and tiles were selected from three large building construction organizations in Sri Lanka. Non-participant direct observations and unstructured interviews were adopted as data collection techniques. A simple arithmetical mean method was adopted to analyse material wastage and a scatter diagram was used to identify the correlation and regression to develop a prediction model. The findings revealed that, when labour experience increased, brick and tile wastage generation decreased, although there were slight fluctuations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
