Modeling a transformational route to infrastructure sustainability in South Africa

Purpose The purpose of this paper is to propose a model for operationalizing the integrated use of lean and sustainability concepts for infrastructure delivery. This model is premised on the need for the attainment of a sustainable built environment through efficient infrastructure delivery. Design/methodology/approach A case study research design was used in assessing five purposively selected cases within Gauteng province in South Africa. These facilities attained Green Building Council of South Africa ratings of 5- to 6-star, for the rating of green buildings and available evidence of integration of lean principles at the developmental stage. Questionnaires were administered to project’s role-players and semi-structured interviews were conducted with the users and facility managers, in order to elicit data for the model development. Questionnaire survey was adopted for the model validation. Findings The lean-sustainability platform for infrastructure delivery demonstrates features such as resources, drivers, barriers, activities, outputs, the results, and the ultimate impact. The findings give insight into various components of the model. It validates its robustness and highlights leadership among other critical factors necessary for successful operationalization of the lean-sustainability ethos required to transform the delivery of infrastructure. Practical implications The developed model provides a transformational route for achieving infrastructure sustainability. The lean-sustainable indicators identified will serve as evaluation tools for assessing lean-sustainability ethos during the delivery phases of infrastructure projects. Originality/value The model provides a new way of thinking about infrastructure project delivery regarding the need to promote sustainability in the built environment.

An abductive approach to qualitative built environment research A viable system methodological exposé

Purpose Qualitative researchers are often confronted with a dilemma of selecting an appropriate approach within which to situate their research. This has led to successive attempts by qualitative researchers in the built environment (BE) to combine two dominant approaches – deductive and inductive; in the conduct of their inquiry. Such attempts can be traced to the poor comprehension of the abductive approach. The purpose of this paper is to elucidate the principles of the abductive approach and illustrate its applicability within the context of BE qualitative research. Design/methodology/approach In this study, an illustrative case study is used to depict the usefulness of the abductive approach in BE research. The case relied upon is a recently completed study of an infrastructure delivery system and an assessment of the system’s ability to deliver on socio-economic sustainability objectives. Findings It was established that extant theories, particularly those with a history of provenance, could be used as a basis for the development of testable propositions for assessing certain phenomena, qualitatively. However, the manner in which these propositions are utilised under an abductive approach is pivotal to the generation of credible findings. Research limitations/implications It is expected that the findings of this paper would create awareness among researchers on the relevance of an abductive approach to qualitative research. Originality/value This study makes an authentic contribution towards resolving the challenge confronting qualitative researchers within the BE discipline as it pertains to selecting between deductive and inductive approaches. In this case, an abductive approach is suggested and its modalities shown through a comprehensive study.

Promoting sustainable development implementation in higher education: Universities in South Africa

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.

A systems approach to assessing organisational viability in project based organisations

Purpose – Extant literature highlights the increasing inability of project-based organisations (PBOs) to meet infrastructure client’s expectations, particularly as it concerns the delivery of socio-economic outcomes during the delivery process. Unclear communication channels and poor processing of information especially as it pertains to client’s strategic objectives results in a misalignment of objectives among participating parties. As its central proposition, the purpose of this paper is to hold that unclear communication channels between parties within infrastructure project PBOs affects their degree of internal cohesion hence posing strong challenges to their overall viability. Design/methodology/approach – Applying the Viable Infrastructure Delivery Systems Model (VIDM); a model premised on the tenets of the Viable Systems Model, this qualitative study proceeds to assess a particular PBO within a developing country to understand its communication and control channels and to identify where gaps likely to affect the internal cohesiveness of the PBO, if any, existed. Whereas semi-structured interviews and project/policy documents were used as data collection tools, data were analysed using pre-set themes. Findings – According the study’s findings, an absence of a prevalent common identity was observed among the various parties to the PBO. Contractors’ capabilities to deliver on time and to budget based on their expertise remained pivotal within the PBO thus abandoning the attainment of the client’s pre-defined socio-economic objectives. Cases of faulty and ineffective organisational architecture, functional and communication issues were observed. Research limitations/implications – Based upon these findings, it is recommended that the VIDM be adopted at the commencement of the PBO lifecycle and used at various intervals by project managers and other stakeholders for assessing the levels of organisational viability. Originality/value – The methodology and findings resulting from this study represent information from fieldwork conducted by the author and as such have not been used elsewhere.

Green business models transformation: evidence from the UK construction sector

Purpose Sustainability has the potential to bring enormous benefits to our built environment. To release this potential, a change in business models is required. The purpose of this paper is to investigate green business models (GBMs) transformation by adopting five essential elements of green value creation and capture: green value proposition (GVP), target group (TG), key activities (KA), key resources (KR), and financial logic (FL). Design/methodology/approach In this qualitative study, 19 semi-structured interviews were conducted. Interviewees were selected purposively. The emergent data were analysed with the aid of themes. Findings It was observed that significant effort was being made towards enabling the transformation of certain elements pertinent to green value creation: KA and KR. This was particularly so when compared to other elements like GVP, TG, and FL. Practical implications Findings from this study should encourage construction managers to align their extant BMs to green activities hence enabling new approaches to green value creation and capture. Furthermore, the study will aid in improving the environmental and economic positions of the value chain within the construction sector. Originality/value This research is one of the few empirical academic works investigating GBMs in the construction sector.
