Abstract

Productivity in the construction industry is a critical factor in project success or failure. However, the construction industry is experiencing productivity challenges emanating from the unskilled worker's usage. This study sought to identify the effects of using unskilled labour on construction output. The study used the qualitative research approach by using semi-structured interview questions to solicit information from 32 construction firms operating from the Northern Cape and Free State Provinces of South Africa. Data received were analyzed through thematic content analysis. Data was collected from the participants in only two provinces in South Africa; however, the findings may be applicable in other provinces. The findings indicate that contractors do not see only the adverse side of utilizing unskilled labour on their projects but only consider its positive aspects. Some of the positive effects identified are low wages paid, financial gain, and training on the job. The adverse effects are reworks, health and safety compliance challenges, poor communication, constant supervision, spending more time on task execution, and training time. Again it was found that, although contractors are aware of the consequences of utilizing unskilled labourers on their projects, they still use them, citing reasons such as the lack of skilled labourers, not all activities required skilled labourers, and being able to achieve project objectives. There is an urgent need to educate contractors on the implications of using unskilled labour on projects. The consequences of using unskilled labour may severely affect the company in the long run compared to the immediate gains experienced. Contractors should regularly improve their workers' skills to enhance their task execution to improve their construction productivity and maximize profits.
