Purpose The construction industry represents most of every country’s finances and vital to continued economic growth and activities, especially in developing countries. The impact of the severe acute respiratory syndrome-2 disease (COVID19) on the government’s income resulted in the expectation of many public projects being cancelled or delayed providing little opportunity for the emergence of new public projects. This study collated a global qualitative perspective (survey interviews) on the lessons learned during the COVID-19 pandemic and the positive and negative impacts for future-proofing the construction sector. Design/methodology/approach In total, 76 respondents from five continents excluding South America responded to the online open-ended structured questionnaire. Data collected were analysed through artificial inteligence analytics tool – Zoho analytics. Findings The themes indicating the positive impact obtained from the interview were overhead cost reduction, remote working environment, focus on health and safety, improved productivity and sustainability goals while the themes signifying the negative impact were low business turnover, delays in construction payment and output, difficulties working from home and job losses. Supply chain management, construction project management improvement, concentration on health and safety and effective virtual working environment were collated as themes on lessons learned. Social implications The major findings of this study emphasise on the need to improve the occupational health and safety and onsite safety measures for future proofing of the construction industry. Originality/value The findings from the analyses made clear the imperativeness of the built environment research, with a focus on novel framework and strategies for future proofing the construction industry.
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.
PurposeAbandonment poses a range of effects detrimental to the development of a country such as Nigeria. Restoring such infrastructure in a sustainable manner is a challenge identified in the literature. The aim of this study is to evaluate a novel approach – the technique for order preference by similarity to an ideal solution (TOPSIS) to identify the sustainability criteria for the redevelopment of abandoned infrastructure in Nigeria. The literature evidences use of TOPSIS in various development contexts, but not in the context of redevelopment of abandoned infrastructure.Design/methodology/approachThis study explores the potential of TOPSIS in the sustainable redevelopment of abandoned infrastructure in Nigeria through a combination of a quantitative method of data collection – questionnaire – and a case study. The case study focuses on the abandoned Federal Government Secretariat in Lagos. One hundred and sixty-one (161) participants responded to the questionnaire. Data collected were analyzed using TOPSIS analytical technique.FindingsRefurbishment is considered as the most sustainable alternative for the redevelopment of abandoned infrastructure. For criteria consideration, structural integrity and foundation categorized under the technological attributes ranked highest for refurbishment and conversion alternatives. Waste generation and prevention and profitability top the list for demolition and procurement respectively.Social implicationsThe social benefit of this study is to bring building considered to be an eyesore back into use.Originality/valueThe findings from the analysis orchestrates the importance of the built environment research concentrating on innovative frameworks for sustainable redevelopment of abandoned structures in the construction industry.
PurposeEstablishing a more sustainable built environment is an increasing global concern for the construction industry. Despite the intrinsic and extrinsic obstacles the stakeholders face, huge efforts are required to transition to a smooth, sustainable construction (SC) practice. This study identifies and discusses cogent obstacles to SC in developing nations.Design/methodology/approachThe Preferred Reporting Item for systematic reviews and Meta-Analysis (PRISMA) approach was employed to establish research work in SC for developing countries. The databases used were Scopus and Web of Science. Meta-analysis of keywords was analysed thematically. The initial broad search returned 8,420 publications which were filtered and reviewed in-depth to fit the aim of the study, produced only 21 relevant publications from the years 2000–2021.FindingsThe four identified themes of obstacles to SC in developing countries are as follows: construction professional training and education, clients' attitudes and awareness, construction industries' culture and capacity and governments' regulation, policies and economy. The key barriers identified from the meta-analysis include inadequate training and education amongst construction professionals, poor execution of sustainability ethics, poor populace attitude towards sustainability, poor awareness and understanding, dearth of precise data and integrated study and inappropriate priorities about sustainability.Originality/valueThe originality in this study are themes drawn from millennium development goals (MDGs) and sustainable development goals (SDGs) publications related to SC. Consequently, the final framework presented a holistic approach to surmounting the established limitations and aided recommendations for future studies. Thus, setting a background for developing strategies to overcome the limitations and further attain sustainable development (SD).
The Nigerian Government is developing infrastructure guided by the United Nations (UN) call for sustainable development. However, uncompleted government infrastructure (roads, bridges, buildings, dams and others) projects litter the entire landscape of the country. This research investigates the causes of infrastructure abandonment in Nigeria through literature review and distribution of questionnaire. It also posits possible solutions to the menace of abandoned infrastructure. Findings from the literature review revealed inefficient procurement processes, defective design, cost overrun, and changes in government (election). From 129 questionnaire distributed to Architects, Engineers, Project Managers, Surveyors, Builders and Construction Procurement Personnel in the built environment both in the public and private sectors in Nigeria, 80 responses were received and analysed with SPSS Pearson Correlation Analysis. The findings from the survey showed that inadequate planning, change in government, faulty procurement, corruption and politics are some of the causes of abandonment. “Changing procurement method” ranked highest in the recommendation for addressing the abandoned infrastructure projects followed by designing with deconstructability in mind. Amongst other recommendations are using innovative management tools and refurbishment of abandoned projects. This research is imperative for the revitalisation of abandoned infrastructure environmentally, economically, and socially and the integration of innovative management tools for the future sustainable procurement of infrastructure.
