| dc.description.abstract | There is a problem of construction waste on construction sites. However, there are various strategies that can be employed; not only on construction sites, but generally on construction projects from the inception of the project to manage construction waste more effectively. Construction waste management can loosely be defined as a function of controlling waste on construction projects to limit its generation and disposal but enhance reduce and recycling. Construction waste mainly arises from design changes, poor choice of construction materials, improper material specifications, inappropriate strategies employed or wrong strategies implemented; leading to poor management of waste on construction projects. Construction waste can be ‘physical’ or ‘non-physical’. Physical construction waste refers to tangible solid waste of materials emanating from construction activities. Non-physical waste pertains to waste of time and project funds in the form of unnecessary expenditure. The aim of this study is to identify waste management strategies utilized on construction sites in Gauteng. Pertinent literature provided a basis of the study. A cross-sectional survey using three construction sites in Gauteng: an office building project, a road project and a civil works project was adopted. The most common strategies were found to be –proper selection of construction materials, proper planning and logical sequencing of construction work activities on a project. There is a variety of branded materials hence the need for proper selection of materials. Further, there are a lot of factors that influence the flow of work activities hence the requirement to keep track and plan activities accordingly to counter distortions. It is acknowledged that strategies found to be common in Gauteng are basic techniques in controlling construction waste generation and the results tied back to the literature. It was established that technological tools like Building Information Modeling are not yet common in Gauteng. Improvements on usage of prefabricated components and offsite manufacturing of components is recommended to stakeholders of the construction industry. It is also logical to conclude that waste management strategies employed on construction sites in Gauteng are anchored on factors of economic viability and government policies. In their quest to make projects profitable and in their efforts to make construction projects compliant to regulations, as a result, construction contractors achieve reductions in waste generation on construction projects. Therefore what the study found out are mainly practices that could, in addition to achieving primary aim, contribute to waste reduction. These strategies identified are implemented primarily to achieve time, cost and quality objectives and thus indirectly waste reduction. | en_ZA |
