Empirical Evaluation of Construction Material Waste Generated on Sites in Nigeria
Abstract: The study
investigates the level of construction material waste generated on building
sites in South-South, Nigeria. The objective is to empirically establish the
level of waste generated on building sites and compare such with the allowable
value in estimates. Data were collected from 30 on-going public building
projects for six months. The level of material waste was calculated in
percentages while one way ANOVA was employed to compare the waste values among
the States in the zone. The significant difference between actual and allowable
values of waste was tested using paired t-test. The level of material waste was
found to be 11.69, 12.10, 10.45, 14.54, and 12.07 for concrete blocks, steel
reinforcement, timber, and tiles respectively. It was concluded that these
values are significantly different, with p-values < 0.05, from the allowable
waste. The study recommends that the values of waste derived by this study be
adopted in estimates
