Governments provide incentives to promote green building practices in the construction sector. Compared with rigid-regulatory incentives, the reward and compensation are voluntary incentives because construction stakeholders can choose whether to uptake them or otherwise. The problem is that an explicit list of the forms of reward and compensation that construction stakeholders may decide to uptake to design and construct green buildings is not available to them. This paper employs a narrative review of academic and practitioner publications obtained in a quasi-systematic manner to reveal the forms of reward and compensation for enhancing green building construction. The findings reveal nine forms of reward and compensation designed by the government as voluntary incentives for construction stakeholders. The new insight from this paper concerns scaling incentives by the government. The scaling in the forms of reward and compensation is low because of the voluntariness in the designing. However, in contrast to the rigid-regulatory incentives, this does not affect their uptake among construction stakeholders. Finally, since the scaling of government initiatives for sustainable development is the norm, this paper proposes that scaling the forms of reward and compensation can be done on the bases of the phases of green building construction.

The actualization of affordable housing remains a challenge. This challenge is exacerbated by the increasing societal demand for the incorporation of sustainability principles into such housing types to improve levels of occupant health and well-being whilst avouching the desired levels of affordability. Innovative technologies and practices have been described as beneficial to the effectuation of sustainable affordable housing. However, knowledge concerning the deployment of innovative technologies and practices in sustainable affordable housing (sustainable, innovative, affordable housing—SIAH) delivery remains nascent. Consequently, there is a lack of a common ontology among stakeholders concerning how to realize SIAH. This study aims to contribute toward the development of this body of knowledge through the establishment of the critical success factors (CSFs) for effective SIAH implementation. To achieve this objective, a systematic review and bibliometric analysis focusing on a juxtaposition of sustainable, innovative and affordable housing concepts was carried out based on the relevant literature. This led to the identification and clustering of CSFs for these housing concepts at individual levels and as a collective (SIAH). The findings of the study consisted of the establishment of four distinct yet interrelated facets through which SIAH can be achieved holistically, namely, housing design, house element, housing production method and housing technology. A total of 127 CSFs were found to be aligned to these facets, subsequently clustered, and conclusively used for the development of a SIAH CSF framework. The most frequently occurring CSFs with predominant interconnections were the utilization of energy-efficient systems/fittings, tenure security, a comfortable and healthy indoor environment, affordable housing price in relation to income and using water-efficient systems/fittings CSFs, and establishing the emergent SIAH CSF framework. The framework in this study is useful in the documentation of SIAH features for construction projects and further studies into SIAH CSFs.

Sustainable development can be attained at a microlevel and having smart campuses around the world presents an opportunity to achieve city-wide smartness. In the process of attaining smartness on campuses, the elements requiring attention must be investigated. There are many publications on smart campuses, and this investigation used the bibliometric analysis method to identify such publications produced over the last decade. A matrix of 578 nodes and 3217 edges was developed from 285 publications on smart campus construction and procurement. Fifteen cluster themes were produced from the bibliometric analysis. The findings revealed that China contributed 48.4% of all published articles on the smart campus. The findings presented a framework from the cluster themes under the four broad infrastructure areas of building construction or repurposing, technology and IT network, continuous improvement, and smart learning and teaching management. The implications of the findings identified that IT project management, traditional procurement strategy, and standard forms of contracts such as the New Engineering Contract (NEC) and the Joint Contract Tribunal (JCT) are applicable in the procurement of smart cities.

Transitioning from demolition to deconstruction practices for end-of-life performances is gaining increasing attention following the need for the construction industry to minimise construction and demolition waste. Building information modelling (BIM) presents an opportunity for sustainable deconstruction. However, the notion of BIM for deconstruction (BIMfD) is still in its infancy in the United Kingdom. Although a few studies on BIMfD are evident, a focus on identifying the underlying factors necessary for successful implementation of BIMfD is lacking. The purpose of this study was to identify and analyse the underlying factors necessary for BIMfD implementation in the UK construction industry. It employed a four-stage research design. The reviewed literature explored extant views on BIM implementation factors to identify an initial list of possible factors influencing BIMfD implementation. Subsequently, a mix of questionnaire, focus group discussions and structured interviews were employed at various stages to refine and contextualise 15 factors necessary for BIMfD implementation in the UK construction industry. The contextual interrelationships among the factors were evaluated using interpretive structured modelling (ISM). This evaluation culminated in a BIMfD implementation factor model. The findings identified BIMfD experts, responsiveness of business models to innovative practices and industry’s acceptance to embrace change as the principal factors influencing BIMfD implementation in the UK. The implications of the findings attest that BIMfD experts and advisors must champion the adoption and implementation of BIMfD in the UK and business models need to become more responsive to accommodate BIMfD innovative practices. A BIMfD framework was conceptualised. Even though the BIMfD framework was designed from the UK perspective, the global construction industry can leverage the outcomes of this study. This paper, therefore, brings to the fore, a hierarchical BIMfD implementation factor model to support improved deconstruction practices in the construction industry.

This paper measured the significant factors leading to performance challenges across state-owned refineries in Nigeria based on experts’ views. The study was carried out with a view of making policy recommendations to help address these issues and thereby improve performance. A quantitative approach was adopted to sample the viewpoints of the professionals who work across the NNPC refineries. Using a Likert-type questionnaire, the professionals’ expert opinions were ranked across four main categories covering political, economic, social, and technical (PEST) factors. A Cronbach alpha test was performed to certify the consistency and reliability of the sub-category factors included on the Likert scale. In addition, a multivariate analysis of variance (MANOVA) was carried out to check for any statistically significant differences in the respondents’ opinions as a result of their different years of work experience. The study revealed that while all four PEST factors are crucial to the performance of the state-owned refineries in Nigeria, political, economic, and technical factors were viewed as more significant than the social factors. A comparative analysis of the sub-category factors using the relative significance index (RSI) and the respondents’ mean scores of importance (RMSI) revealed that government interference, funding issues, political indecision, theft and pipeline attacks, cost of spare parts, maintenance issues, operating capital, feedstock supply, staff training and competence issues are some of the significant factors that affect the performance of the refineries. The identified performance challenges from this study were used to inform policy recommendations to help address the problems of the refineries.

This study espouses a multi-strategy method comprising of a qualitative study and system dynamics (SD) to deliver the long-term dynamic behaviour of human resource development (HRD) in Ghana’s oil and gas sector. The adoption of the SD differed from previous studies addressing the local content implementation challenge of human resources, thereby allowing HRD to be considered a ‘system’ which, in turn, aided in comprehensively identifying and analysing the interrelationships among the dominant variables. Focal articles were reviewed to develop a causal loop diagram (CLD) for human resource and subsequently validated qualitatively. The CLD was used for analysing interconnections among the variables in the HRD and as a basis for developing the stock and flow diagram for projections. The study found that local content investment is projected to increase from $799 million to $3.0807 billion in 50 years, with a corresponding revenue increase from $29 billion to $44 billion in 50 years. Subsequent sensitivity analysis compared the local content model results under varying situations, which indicated the possibility of a demand for 20,000 local staff. The study further uncovered two critical issues affecting HRD, namely policy coordination and harmonisation and sustainable funding. These issues are exacerbated by the pervasive political interference in the administrative and operational functions of state oil and gas institutions.

An identification of strengths, weakness, opportunities, and threats (SWOT) factors remains imperative for enabling a successful Smart Campus transition. The absence of a structured approach for analyzing the relationships between these SWOT factors and the influence thereof on Smart Campus transitions negate effective implementation. This study leverages a systems thinking approach to bridge this gap. Data were collected through a stakeholder workshop within a University of Technology case study and analyzed using qualitative content analysis (QCA). This resulted in the establishment of SWOT factors affecting Smart Campus transitions. Systems thinking was utilized to analyze the relationships between these SWOT factors resulting in a causal loop diagram (CLD) highlighting extant interrelationships. A panel of experts drawn from the United Kingdom, New Zealand, and South Africa validated the relationships between the SWOT factors as elucidated in the CLD. Subsequently, a Smart Campus transition framework predicated on the CLD archetypes was developed. The framework provided a holistic approach to understanding the interrelationships between various SWOT factors influencing Smart Campus transitions. This framework remains a valuable tool for facilitating optimal strategic planning and management approaches by policy makers, academics, and implementers within the global Higher Education Institution (HEI) landscape for managing successful Smart Campus transition at the South African University of Technology (SAUoT) and beyond.

The incessant reportage of cost overruns and abandoned projects in contemporary literature have accentuated the need for a re-examination of the nature of the cost management strategies deployed to these projects. This study explores the potential of kaizen costing strategy to engender effective cost management within construction project delivery systems in developing countries. Data collected during this study were analysed using the analytic hierarchy process (AHP) and systems thinking approaches to determine the criticality of the factors influencing the effective implementation of kaizen costing. Seven (7) archetypes leading to final causal loop diagram identified the incorporation of the plan–do–check–act approach to project and cost planning, the budgeting system of the construction companies, overhead cost reduction during construction and the overall procurement process. Executing these archetypes will potentially reduce high overhead costs, project cost and time overruns, as well as enhance construction industry sector growth policies and construction organisation corporate governance.

There are an increasing number of corporate social responsibility (CSR) reporting tools that are evolving. As a result, it has become chaotic and complicated for practitioners to select the most appropriate one for CSR reporting. To address the problem, previous studies have classified the CSR reporting tools into frameworks, standards and, ratings and indices classes for easy comprehension and application in practice. However, no study has focused on revealing the use of CSR reporting tools based on this classification. This study employed researchers’ perspectives through a systematic review of journal papers published between 2001-2016 to reveal the use of CSR reporting tools based on their classifications. The findings revealed that the GRI tool in the framework class is widely implemented, but also associated with many problems that impact CSR reporting in practice. Also, there are new aspects where the tool could be used are for CSR learning in organisations and CSR regulation. Furthermore, the CSR reporting tools in the standards, ratings and indices classes are not commonly implemented for CSR reporting thereby attracting less researcher interest. The study concluded by linking the research and practice of the use of CSR reporting tools in different classes. The study has implications for CSR reporters who use CSR reporting tools in the frameworks, standards, and ratings and indices classes.

Packaging waste production, especially single-use containers, is exerting detrimental effects on terrestrial and aquatic ecosystems, including human health. To internalise the externalities associated with single-use containers, different instruments, including a deposit refund scheme (DRS), have been operationalised in many countries. Therefore, DRS is introduced in Scotland to reduce plastic litters by increasing recycling rates and incentivising pro-environmental behavioural change. This study addresses the complexity of single-use plastic containers by analysing consumers’ perceptions regarding the introduction of DRS in Scotland. Using 940 comments from the BBC “Have Your Say” messageboard, this study adopts sentiment analysis to understand consumers’ opinions about the introduction and implementation of DRS in Scotland. Findings suggest that a UK-wide scheme that is similar in terms of operations and structure is required for DRS to be successful. While consumers’ knowledge and opinions about DRS are mixed, the efficacy of DRS including its relevance is questioned and raises doubts about its contribution to sustainability. The findings imply the need for UK countries to negotiate and collaborate on appropriate and attractive interventions in addressing post-consumer single-use plastic containers. The implications of the findings for policy and practice, especially in improving the operations of DRS are further discussed.

He sub-optimal performance of state-owned refineries in Nigeria has led to a significant gap in the supply of refined petroleum products (RPPs) in the country. More so, the growing demand for these products has further widened the gap to the range of 500,000 –600,000 barrels per day (bpd). Consequently, most of the imports for RPPs in Nigeria are being filled from the United States and North-Western Europe at the expense of the Nigerian economy. However, given the abundance of petroleum resources in Nigeria and its long history in the production of oil, it is unfortunate that the local refineries are hardly maintained to meet the needs of the local population. In addition, the inability of the Nigerian state to build additional refining capacity to cushion its domestic supply gap for RPPs has become a major concern. With more than 40 licenses issued to private companies since 2002, only two companies (Niger Delta Petroleum Resources Refinery and Dangote Oil Refinery) have made noticeable progress in new refinery construction.This paper is focused on investigating the current challenges of refinery construction in Nigeria. This is done with a view of comparing the drivers and enablers of productivity in construction in this sector during the period of 1965 –1989 and how they differ from the current period of 2000 -2019 in Nigeria.A systematic literature review within the academic journals, source documents from the industry, relevant interviews from published news media and consulting organisations were used to identify and categorise these challenges. The findings of this study were validated by interviews from experts across key industries in this sector.The study reveals that change of ownership structures from the government sector to the private sector between the two eras, present additional challenges. These challenges cut across availability of capital, inconsistent government priorities and access to land for construction. Others include cronyism and corruption, weak political will, unstructured refinery licensing scheme, security challenges and economic factors regarding the regulated downstream market inNigeria. Key recommendations proffered to help solve these problems include a private sector-led partnership with the government in the form of public private partnerships (PPPs), a review of existing methods for licensing refineries for private organisations, the development of local manpower with relevant technical skills to help lower the cost of expatriate labour and the establishment of more designated clusters as free trade zones within the oil-producing Niger Delta. These recommendations will help lower the entry barriers for private organisations in this sector

The post-contract phase of the construction process remains critical to cost management. Several techniques have been used to facilitate effective cost management in this phase. However, the deployment of these techniques has not caused a reduction in the incidence of cost overruns hence casting doubts on their utility. The seeming underwhelming performance posted by these post-contract cost control techniques (PCCTs), has been traced to improper deployment by construction project managers (CPM) and quantity surveyors (QS). Utilizing the perspectives of CPM and QS professionals, as elicited through a survey, produced 135 samples. The instrumentality of the artificial neural networks (ANN) in this study enabled the development of a structured decision-support methodology for analysing the most appropriate PCCTs to be deployed to different construction process phases. Besides showcasing the utility of the emergent ANN-based decision support methodology, the study’s theoretical findings indicate that CPM and QS professionals influence decisions pertaining to PCCTs choice in distinct phases of the construction process. Whereas QS professionals were particularly responsible for the choice of PCCTs during the initial and mid-level phases, CPM professionals assumed responsibility for PCCTs selection during the construction process close-out phase. In construction cost management practice, the crucial PCCTs identifies more with the application of historical data and all cost monitoring approaches.

Loss of productivity through on-site delays and disruptions is a significant problem in the construction industry. This can be caused by workforce, materials, and equipment clashes. A major need for the industry is to improve construction logistic efficiencies for materials and equipment from manufacture to the point of use by the workforce. The authors investigate the effectiveness and efficiency of integrated construction supply chain logistics (ICSCL) using 4D Building Information Models (BIM), via three information streams: literature, a case study of the Elephant and Castle project (E&C), and a survey from UK construction professionals. The results illustrate, although BIM of various levels is currently in use throughout the UK, 4D BIM for ICSCL is not extensively utilized due to an absence of strategy, perceived costs of IT, and training requirements. That use could potentially add value with a trusted supply chain and disciplined planning using a multiple stream logistic model.

PurposeContinual cost reduction of overhead costs of building projects can realign the concept of post-contract cost control towards value-driven construction projects and stakeholders’ satisfaction. This study synthesised and analysed the viable continuous improvement measures critical for waste reduction during the execution phase of a building project.Design/methodology/approachA review of existing literature facilitated a list of continuous improvement measures. This literature review findings enabled a Likert-scale questionnaire which was administered to two-hundred and fifty (250) small- and medium-scale construction companies (SMSCC) in Nigeria. Multiple linear regression statistical tests deduced the significant cost reduction measure from which a causal loop diagram was designed to indicate continuous improvement measures during the execution phase of a building project.FindingsCogent construction activities associated with overhead costs were deduced from the statistical tests as being payment of suppliers and sub-contractors and purchase orders. An all-inclusive casual loop model for cost reduction through waste minimisation in construction projects as a viable oriented mechanism for meeting clients' requirements was developed.Practical implicationsThe causal loop continuous improvement model recognised external and internal factors which are crucial for SMSCC to focus on for their organisational growth and performance enhancement.Originality/valueA focus on non-physical waste in construction organisations potentially addresses behavioural challenges for continuous improvement.

Purpose The development of corporate social responsibility (CSR) in the construction sector is slow, thereby leaving many opportunities for further development. To enable operators in the construction sector to effectively capitalise on the opportunities to promote the development of CSR in the sector, this study employs the practice viewpoint to take the stock of CSR activities in the sector. The purpose of this paper is to reveal the state of CSR practice in the construction sector. The study also draws from the development of CSR in the manufacturing, mining and banking sectors to inform the state of CSR practice in the construction sector. Design/methodology/approach This study carries out a systematic literature review of 56 journal publications that were published between the year 2000 and 2016. The deductive coding of the publications was done to identify four themes of CSR research that constitute the practice view of the state of CSR in the construction sector. Findings The implementation of CSR is the major emphasis in the state of CSR practice in the construction sector. The implementation of CSR is wrapped in the perception of operators about CSR potentials, dimensions of CSR implemented, strategies for implementation and the effects of the implemented CSR practices on performance. The sector characteristics and organisational structure are attributes for comparing the CSR practices between the construction sector and the manufacturing, mining and banking sectors. Originality/value This study provides a researchers’ view of the state of CSR in the construction sector. Additionally, the study draws from the development of CSR in the manufacturing, mining and banking sectors to inform the state of CSR practice in the construction sector.

PurposeThe purpose of this paper is to present a capability maturity model (CMM) developed to implement continuous improvement in small and medium scale construction companies (SMSCC) in Nigeria.Design/methodology/approachA multi-strategy approach involving qualitative studies of SMSCC in Nigeria was conducted. Semi-structured interviews were conducted with purposively selected construction experts in Nigeria to identify variables essential for continuous improvement in SMSCC. Data collected were thematically analysed using NVIVO. Subsequently, a system thinking approach is employed to design and develop the CMM for implementing continuous improvement SMSCC, by exploring possible relationships between the variables established.FindingsCMM provided a five-level approach for the inclusion of investigated variables such as team performance; culture; structure; post-project reviews, financial risk management, waste management policy and cost control. These variables are factors leading to continuous improvement in SMSCC, implementable within a six to seven and a half years’ timeline.Practical implicationsThe system thinking model revealed cogent archetypes in the form of reinforcing loops that can be applied in developing the performance of SMSCC. Continuous improvement is feasible. However, it takes time to implement. Further longitudinal studies on the cost of implementing continuous improvement through CMM a knowledge transfer project can be initiated.Originality/valueA methodical strategy for enhancing the effectiveness and operations of SMSCC in developing countries can be extracted from the causal loop diagram and the CMM.

Purpose Kaizen in construction is a new paradigm stemming out of lean production systems. Construction companies in developing economies, such as Nigeria, have a task to innovate to liquidate in certain cases. With the aid of kaizen, which encompasses the benefit of stakeholder relationship improvement and management, profitability enhancement and delivery of projects to satisfied clients, construction companies can realise expected growth. An exploration of the critical success factors (CSF) and associated drivers within the limits of the scope is essential. The paper aims to discuss these issues. Design/methodology/approach Exploratory factor analysis statistical tests categorised the CSF identified in the literature review section. A detailed sampling approach extracted 135 questionnaires under the five-point Likert scale format from a larger population in Nigeria. An exploration of important drivers and iteration of eigenvalues combined with asymptotic significance of the drivers provided the CSF and significant drivers. Findings Construction management function, operational efficiency, construction business ethics and construction cost management were the CSF established from the exploratory factor analysis tests. It was confirmed that kaizen can be adopted in Nigerian construction companies with reflections on the principal drivers for the CSF. Research limitations/implications The exploration of the CSF and drivers associated with kaizen implementation can be applied to other developing countries with considerations of implementation in terms of cost and time. Originality/value The identification of CSF provides ample opportunity for consideration of kaizen in construction companies. The findings of this study are a basis for investigations into cost and time implications of kaizen adoption in construction companies.
