Abstract

The Ethiopian construction activities have grown exponentially, but the construction management practices are poor. The construction industry in Arba Minch is an active and crucial segment in the economic development of the town. The general objective of this study was to investigate the factors affecting construction material wastage on building works. This study also identifies the main causes, determines the percentage of construction materials, ranks and analyzes the main effect on the group of factors, and measures the minimization practices of construction material wastage on building works. The data analyzed was calculated using the relative importance index (RII) and the numerical formula to determine material quantity data. The research discovered that the major factors that cause construction waste in building projects were materials, which were quantified as per the percentage level of wastage: coarse aggregate (13.15%), fine aggregate (12.55%), HCB (12.25%), reinforcement steel (8.95%), concrete mix (8.25%), and cement (6.11%) are the key materials wasted on construction sites. Therefore, this study concluded that, in order to minimize wastage on building works, good construction management, proper storage and handling of materials, reuse of waste materials, and the use of appropriate software packages to minimize design changes and overordering should be practiced.
