The target population for the study is the key professionals in the Nigerian construction industry and they are: Architects, Builders, Engineers, Quantity Surveyors and Town Planners. A sample size of 1,231 professionals was determined using Taro Yamane formular for determining sample size for a finite population.

The results of the study show that the identified building collapse risks have significant effect on the professionals in the Nigerian construction industry. The result of the mean shows that the key building collapse risk factors that impact significantly on the professionals include; loss of reputation (6.04), waste of resources, time and labour (5.98), loss of lives (5.78), among others. The building collapse risks that have predominant effect on the professionals in the Nigerian construction industry are: loss of reputation, waste of resources, time and labour, withdrawal of practicing licenses and loss of trust.
