Purpose-This study aims to review the zeal exhibited by universities in South Africa towards aligning institutional mandates of teaching, learning, research and community engagement to the sustainable development (SD) agenda. The implementation of the SD agenda across higher education institutions (HEIs) continues to draw attention from the wider society. This is because HEIs are increasingly being looked up to for leadership in this regard. However, although several studies are quick to identify various factors which have driven the adoption of sustainable practices in HEIs, the paucity of studies seeking to identify the drivers for SD implementation remains glaring. This is particularly so in developing countries like South Africa. Design/methodology/approach-To confirm the exploratory data from desktop study on public university engagement with sustainability in South Africa, a single case study was conducted in the Central University of Technology (CUT). The single case study design adopted semi-structured interviews and document reviews as data collection techniques. Purposive snowballing sampling technique was strictly adhered to in the selection of interviewees. Interviewees were selected on the basis of their roles in the implementation of the CUT's sustainability agenda. Findings-Data emanating from these interviews were analysed thematically using qualitative content analysis. Although a plethora of drivers were identified, there appeared to be a consensus between most of the interviewees that the quest for cost reduction remained the most significant driver for the viable implementation of the sustainability agenda at CUT. Research limitations/implications-It is expected that findings from this study would provide a platform for the development of effective implementation strategies in South African HEIs. Also, the findings contribute to filing the extant gap observed concerning implementation and drivers for engendering SD implementation in HEIs in sub-Saharan Africa (SSA) region. Practical implications-By highlighting the drivers for SD implementation, this study contributes to the development of a more receptive social ontology among various stakeholders in an HEI towards the agenda, particularly within the SSA context where there is low level of awareness and buy-in by these stakeholders. Originality/value-This study makes an original contribution to the research base of SD in HEIs and implementation.

Purpose – Non-value adding activities (NVAAs) are considered to be problematic in the management of projects. Reported research findings suggest that these NVAAs consume resources without necessarily adding value to completed tasks. The main aim of the research is to provide insights and plausible explanations concerning how NVAAs can propagate poor performance in South Africa. Design/methodology/approach – The paper reports on a quantitative survey conducted among public sector clients, consulting engineers, and civil engineering contractors in South Africa. Using a framework that was developed from the literature reviewed, the study proposed three conceptual qualitative models that were based on system dynamics. Findings – The study suggests that NVAAs that are prevalent in South African construction can impact project performance negatively in the form of cost and time overruns. It can also be argued that although there is commonality between NVAAs that are identified in South Africa and other countries, their frequency and effects on project performance differ. Research limitations/implications – The findings provide further insights about NVAAs that are related to the South African infrastructure sector only. Originality/value – The study, which is the first of such in South Africa, could lead to increased awareness among South African project stakeholders that are concerned about performance improvement from the lean construction perspective.

Purpose – The purpose of this paper is to assess the level of collaborative working among project partners in South African construction. The construction industry is made up of a plethora of entities trading as consultants, contractors, subcontractors, suppliers and manufacturers. The effort and contributions of these entities with the input of clients result in completed projects. However, the performance of the industry has continued to generate more negative, rather than positive, headlines. Typical headlines include defects, rework, delays, injuries and accidents, all of which are mostly blamed on the endemic fragmented nature of the industry. Design/methodology/approach – The assessment was undertaken through a quantitative survey conducted among general contractor (GC) members of the Master Builders South Africa. Findings – Selected findings relative to the research include short-term objectives and price-oriented approach are prevalent in the industry; poor problem-solving mechanisms exist between project partners; poor use of modularisation; significant numbers of irregular clients and rigid adherence to contents of contract data. Research limitations/implication – The research findings provide an insight rather than definitive information due to the limited response rate of the survey. Originality/value – The paper concludes that contractors should embrace collaborative procurement methods to improve performance and promote innovation in the industry.Recommendations include the availability of a consistent work load for the supply chain members as well as the improvement of the relationship between project partners, especially between contractors and their subcontractors/suppliers.

PurposeWith recent extreme weather change from global warming, the ever-increasing volume of waste, and the unsustainable use of natural resources, there is the need to evolve a new way by which building construction projects are constructed to reduce carbon emissions, environmental degradation and excessive resource consumption. It is based on this premise that this paper presents the level of implementation of sustainability practices during building construction projects in Nigeria.Design/methodology/approachThis study adopted the mixed methods research approach that involves collecting quantitative and qualitative data through the use of questionnaire and interviews. The numeric data were analysed using descriptive and inferential statistics such average percentages, mean item score, Kruskal–Wallis and Mann–Whitney U tests whereas the textual data were analysed thematically.FindingsFrom the questionnaire survey, the result shows that the awareness level of sustainability practices by construction professionals is high in the study area. Also, the findings indicate that “choosing the right construction method for resource conservation and consideration of the client’s satisfaction” is the major sustainability practices that construction professionals implement in the construction phase of building projects in the study area. Insights from the interviews align with the findings from the questionnaire survey.Originality/valueThis study concluded that the awareness level of sustainability practices is high in the study area and “choosing the right construction method for resource conservation” and “consideration of the client's satisfaction” are the major sustainability practices that construction professionals are aware of and is being implemented in the study area. Based on these findings and conclusions reached, it is recommended that construction professionals should improve their knowledge of sustainability to enhance their competence for the effective implementation of sustainability practices during building construction projects in Nigeria.
