Reduction Potentials of Material Waste Control Construction Methods on Building Sites in South-South, Nigeria

Material waste reduction or minimisation reflection is essential in the studies of construction waste management, and it cannot be overstressed due to waste impact on project performance and outcomes. There are some construction methods and on-site management practices, termed in this study as material waste control construction methods (MWCCM), which were adopted from the manufacturing sector, which can curb the level of material waste generated on-site. The purpose of this study is to assess the extent of utilisation of MWCCM for alleviating material waste problems and domestically establish their potentials in reducing waste on-site. The correlation and relationship between MWCCM and material waste generated (MWG) on-site were determined. The study was carried out in the six States of South-South geopolitical zone in Nigeria using a work study manual to collected data from the selected on-going projects in the study area. The descriptive research survey design approach was espoused for the study, and the data were equally analysed with canonical correlation. The study findings revealed that the squared correlation coefficient (r2) type effect size was 0.808, showing that the full model clarified a generous segment, about 81% of the variance shared between MWG and MWCCM. It demonstrates unique relationship between MWG and MWCCM with F = 2.918 at p < 0.05. Sequel to the results derived by this study, conclusions were reached that there are a significant correlation and relationship between MWG and MWCCM. Hence, MWCCM has great potential for reducing material wast on site. The study recommended MWCCM for use to assuage the menace of material waste generation on site, thereby improving the performance of project delivery
