Abstract
Waste occurs in building sites in varying levels from different materials. The ability to control the
wastage of a particular material also differs from one site to another. However, previous works
reveal that estimators’ allowances for materials waste are usually exceeded for most materials on
sites. This study therefore proposes to evaluate the wastage and control of construction materials
in 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.
