EVALUATION OF MATERIALS WASTAGE AND CONTROL IN SOME SELECTED BUILDING SITES IN NIGERIA

Waste occurs in building sites in varying levels from different materials. The ability to control thewastage of a particular material also differs from one site to another. However, previous worksreveal that estimators’ allowances for materials waste are usually exceeded for most materials onsites. This study therefore proposes to evaluate the wastage and control of construction materialsin selected building sites. The population of the study is construction professionals in some selected building sites in Nigeria. It involves the use of a questionnaire administered via accidental sampling technique while descriptive statistics tools were used for the analysis. The study reveals that estimators’ allowances for materials wastage are exceeded for most materials on sites. Block work has the highest level of waste generation and adequate site supervision and control is the most important strategy for minimizing materials wastage on sites. The study recommends that site managers should endeavor not to exceed estimators’ allowance for waste on their projects. Experienced and requisite professionals should also be engaged in construction projects for adequate site supervision and control.
