Appraisal of Construction Health and Safety Risk Management in Nigerian Construction Industry – a case study of the Building Industry

ABSTRACT The study examined the state of health and safety risk management practices in the building sector of the construction industry and has the objectives to: evaluate the construction risks inherent in the building sector of the construction industry; examine the health and safety risk management processes adopted by the construction industry in Nigeria; validate the existence of identified factor(s) militating against the implementation of health and safety practices in the construction industry in Nigeria; and investigate if there are established frameworks for effective health and safety risk management in the construction industry of Nigeria. The study adopted the survey and case study research design. It employed the use of Delphi’s technique in the distribution of questionnaire and made use of chi-square analytical technique for the analysis of gathered data. The findings revealed that: most of the parties involved in construction projects do not have any significant health and safety risk management process in place; the identified factors militating against the implementation of health and safety risk management practices are still valid; there is no existing established framework for effective regulation of health and safety risk management practices. Various improvement strategies have been suggested.
