Estimating the Contribution of Various Construction Materials on Construction Waste Generation Onsite in South Eastern Nigeria.

There are many challenges arising from the generation of construction waste onsite, chief of them are environmental pollution and material loss. A number of factors can lead to the generation of construction waste. Hence, the objective of this paper was to ascertain the construction material that leads greatest onsite generation of construction waste in Nigeria using structured questionnaire to gather data from primary source by surveying fourteen most common construction materials. Results obtained revealed that timber, ceramic tiles and mortar ranked 1st, 2nd and 3rd with standard deviation of 1.14, 1.156 and 1.265; while roofing sheets, PVC water pipes and paint contributed the least 12th, 13th and 14th with a standard deviation of 1.115, 1.222 and 1.095 respectively.
