It is believed that building material wastage on construction sites account for cost overruns and any improvement

in building materials management on construction sites

has the potential to enhance the construction industry’s

performance with cost-saving benefits. The purpose of this

study is to identify the most wasteful building material during

construction operation. It also sets out to assess the level of

material wastage with various subcontracting options, the

percentage contribution of material wastage to project cost overrun, identify factors contributing to material waste on building

sites and to examine the relationship between subcontracting

options, project cost overrun and the level of waste generated

from building material. A survey research design was employed.

Responses from 56 site based professionals representing 70%

of the respondents were analysed using both descriptive and

inferential statistics. Results indicate that the most wasteful

building material during construction operation is mortar from

plastering-rendering; labour-only subcontracting options have

high contribution to material wastage. Furthermore, the study

revealed that the average percentage contribution of building

material wastage to project cost overrun is between 21-30%;

Poor supervision, re-work, and poor material handling were

identified as dominant factors that have high contribution to

material wastage on sites. Finally, the result also shows that

there is a relationship between subcontracting options, cost

overrun and waste generated from building material during construction. Measures to reduce material wastage on construction

sites were proposed.Improvement in building materials management on construction sites has the potential to enhance the

construction industry’s performance with cost-saving benefits.
