    Management of e-waste in the South African construction industry : a literature review
    (IEOM Society International, 2023) Nkosi, Thalente Lungile; Adedeji, Jacob; Jele, Nkosinathi; Hadebe, Phumzile
    In complacence with the ever-growing industrialization of different sectors, more specifically the construction sector, electrical and electronic waste management is becoming a global challenge in the construction industry posing significant environmental and health challenges. E-waste, if managed effectively, will release significant economic, resource and ecological benefits. Most of the construction companies have no information about electronic waste management, electronic devices that come from the seller while damaged are sent back to the supplier for exchange. Electronics that could not be repaired are sold to scrap yards and some are sent directly into the dumpsite, however, there were some electronic wastes stored inside the premises and others stored at the back of the premises directly into the ground, which decomposes and possibly affect the environment. The construction companies feel that it is the government's responsibility to provide money for electronic waste management otherwise there is no way they could manage e-waste in their business because it will not be profitable or else the users must take care of their electronic waste. The secondary data was collected through a detailed review of extant literature. In contrast, the primary data was collected using a qualitative method through interviewing the construction professionals. Twelve industry professionals were invited to participate in an interview but ten were present and able to participate, representing an 83% response rate. This paper seeks to assess how electrical and electronic waste are managed in the South African construction industry.

    Academic training evaluation of building technology programme
    (Department of Construction Economics and Management, University of Cape Town, 2022-08-01) Obaju, Biodun; Fagbenle, Olaposibo; Amusan, Lekan; Olaniran, Temitope
    Training evaluation is one method through which tertiary institutions examine the effectiveness of the training they deliver in order to establish their students' readiness for the workplace. However, several higher institutions' evaluation methods have been confined to assessment in tests and exams without considering the knowledge and competencies acquired by students via training in fulfilling workplace expectations. Hence, the study assessed the training received by Building technology graduates in construction management and construction technology courses. The study adopted the Kirkpatrick model's first two stages of training evaluation (Reaction and Learning levels) with a questionnaire distributed to purposively selected Building technology graduates from two polytechnics in Southwestern Nigeria using a snowball sampling technique. Data obtained were analysed using descriptive statistical tools. The study's findings show that respondents were satisfied with the training acquired and possess the basic competency from the training. However, the graduates lack sufficient knowledge of laws and regulations governing construction work, the use of computer programme for planning and scheduling projects and the ability to use tools and equipment for construction work. The study findings imply that building graduates would be unable to work adequately in the construction industry without additional training, putting enormous strain on construction firms to re-training them to meet their expectations. Tertiary institutions need to revamp their training strategies and methods for students to improve their competency to strive in the construction industry.
