Infrastructure development and abandonment.

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
