M.Tech. (Construction Management)
Wastage on construction sites poses a big problem to the South African construction industry as
more and more wastage generated is not properly disposed. This is so because with the chase by
the South African government to go low carbon wastage has become problematic for the South
African construction industry. This study seeks to determine the the causes of material wastage on
Gauteng Province construction sites, the effects of material wastage on the contractors, the impacts
of wastage on construction projects, how can wastage be reduced and better managed on a
construction site and the benefits of minimised wastage on construction sites in the South African
construction industry
The data used in this research was derived from both primary and secondary sources. The
secondary data was collected through a detailed review of related literature. The primary data was
collected through a questionnaire which was distributed to registered and non-registered
construction professionals practising in the industry. One hundred and fifty-three questionnaires
were received from two hundred sent out, representing a 77 per cent response rate.
Findings from the research were analysed using descriptive statistics. Findings from the
descriptive analysis revealed that the primary causes of material wastage on the construction site
are design and construction errors, design changes and incorrect specification. Wastage in the
procurement process is caused by a lack of allocated responsibility for decision-making,
incomplete procurement documentation, and poor coordination among parties. Furthermore,
material wastage in material handling is due to shipping and suppliers’ errors, inappropriate
handling, and inappropriate storage. In addition, causes of material wastage in site operation are
poor site management and supervision, and a lack of knowledge about construction during design
activities. Material storage wastage is caused by materials being stored far from the point of
application, and improper storing methods. Furthermore, contractual causes of wastage are..
