Abstract
The study focused on the management of building collapse risks (BCR) in Nigeria: A post mortem investigation. Management of building collapse risks has been saddled with a lot of challenges which had led to continuous rise in the risks associated with building collapse. The main objective of this research is to investigate the management of building collapse risks in Nigeria with a view to developing a framework for effective management and reduction of losses associated with building collapse in Nigeria. To achieve the main objective of the study, five specific objectives were pursued and four hypotheses were formulated to guide the study. A survey research design was adopted for data collection. The population of study was made up of key professionals in the building industry, Staff of emergency management agencies, as well as the neighbourhood of the collapsed building in the study areas and the total population is 24,229. A sample size of 1997 was determined using Taro Yamane formula for finite population, while the samples were selected using stratified random sampling technique. A total of 1860 correctly filled and returned copies of the questionnaire, representing 93% of the distributed copies of the questionnaire was used for data analysis. Data were presented using tables, bar charts and pie charts, while analysis was done using percentages, mean and relative important index (RII). The hypotheses were tested using analysis of variance (ANOVA) and principal component analysis (PCA) via SPSS, version 23 and Minitab 18. The following findings were made from the analysis: (i) The existing system of managing building collapse risks in Nigeria is poor, ineffective and cannot adequately be used to address the risks associated with building collapse. (ii) The building collapse risks that mostly impact on the building development and Nigerian economy are economic/financial risks and human related risks. (iii) The prominent challenges faced by emergency management agencies are: lack of adequate funding, coordination and collaboration, poor urban planning, etc. (iv). The study developed and validated a framework for effective management of risks associated with building collapse in Nigeria, which is the major contribution to knowledge. The study therefore recommends adequate funding and monitoring of emergency management agencies, coordination and collaboration network among all stakeholders involved in disaster management, among others.
