Waste in the construction industry has been the theme of several research projects around the world in recent years. Researchers implement different methods to reduce the amount of waste in the construction industry. In the construction industry, contractors only consider physical waste which leads the project to cost overruns. i.e. material waste. Construction industry is also affected by time overrun. Impact of time overrun on the construction projects is considerably high and requires special attention in addition to physical waste. In the present study, construction waste is categorized in mainly of two types: value added waste and non-value added waste. This categorization includes both-material waste as well as time waste, which are main causes of occurrence of waste. A case study was also carried out at a residential building project in Ahmedabad, Gujarat to get the idea about the percentage of waste occurs in a construction project.
