Investigation Into Waste Management on Construction Sites in South Western Nigeria‪.‬

Abstract: This study aims to report investigation into the problem of waste management on construction sites in South Western Nigeria and to unveil inherent dangers material wastage poses to the construction Industry. In the construction industries, materials are very vital on building sites, but not all the materials delivered are used for the purposes for which they have been ordered and the subsequent disappearance of these materials constitute part of waste. The primary research instruments used was the questionnaire which contained varied questions on material wastage and management. The investigation revealed that material wastage brings about additional cost to the construction project as well as a reduction in the profit of the contractor, considering the cost of storing and transporting construction waste along with the loss of revenue from not reclaiming waste. Also, most waste that occurs on construction sites is due to poor management and lack of awareness on effective waste management. The study finally recommends that recycling and reusing of construction waste is a viable option in construction waste management and that material wastage can be reduced by giving incentives to the workers for good handling of materials and by having trained personals to supervise the works. Key words: Construction Waste, Waste Recycling, Waste Reusing
