Construction activities in Nigeria have made the industry a focal risk point. This is because several building collapses which has resulted into huge losses of properties and human lives are yet to be curtailed. Some authors have written on this issue but it was observed that the spontaneous collapse of buildings in different locations has not yet triggered expected regulatory review in Nigeria. There are several reported and unreported total and partial collapse of buildings in major Nigerian cities like Lagos, Abuja, Onitsha, Kano and Port Harcourt, etc. Despite the availability of reliable building codes widely used in design; construction industry in Nigeria is still failing to meet acceptable standards; thus, resulting into risk of structural defects and subsequent building collapse. To find lasting solutions to tackling the challenges, this paper examines risk factors responsible for building collapse and its impact on Nigerian economy. Questionnaire and interview were used as instruments of data collection. The data gotten were analysis using tools like spearman’s ranking and T-test. The findings revealed that usage of unapproved materials; defective design and engagement of quacks as major construction operators are the top ranked factors with an overall mean of 4.12, 3.96 and 3.87 respectively. T-test also reveals that at 95% confidence level, all the assessed factors were significant, as a significant p-value of 5 was derived for all the assessed factors. Loss of materials and capital investments, Psychological trauma and creating damaged image to the country and loss of lives of RII of 0.87, 0.85 and 0.83 were highest rankings respectively as identified impact of building collapse in Nigeria. It was concluded that all the identified factors are all significant and their impact are significant on the live of the people, the economy and the country’s image. Mitigation measures were proffered to curb its further re-occurrence or control.
