Abstract
Despite the efforts to improve the quality of construction works through use of advanced technology, increased labor force for professionals in the construction industry, increased availability of construction equipment, there is still low quality work. Building failures result into economic and temporal deviations in construction industry. The purpose of this research is to develop strategies to mitigate building failures in the construction industry in Nigeria. Descriptive survey research design was adopted for this research in some selected urban cities in Osun State. The study population comprised of 210 respondents: Supervising engineers, Site engineers, Site foremen, Clerk of works and Clients. Causes of building failures were categorized as: consultant related; contractor related, construction related, client related and external related factors. The data collected were analyzed using correlation and regression analysis with SPSS.. Findings were presented using descriptive charts and tables. The findings indicated that Inadequate supervision of works (RII= 0.79); Shortage of equipment and materials (RII=0.76); Cash flow problems (RII=0.67) and Inflation in prices (RII=0.70) were the leading causes of building failure in their respective categories. Based on study findings, it was concluded that there is a great influence of consultant related factors on the causes of building failures more particularly related with inadequate supervision of projects. Defects result from non-conformance to requirements and always result in rework. The overall causes of defects can be attributed to design, construction, material and subsurface conditions. Finally, the causes of defects lie in inadequate management or inadequate technical skills. The descriptive analysis clearly indicates that construction-related causes dominates.

Highlights
The main function of the construction industry is to provide infrastructure that protects the life of users and or occupants and contents from the weather, mainly rain, wind and extremes of temperature
The possible causes of building failures were identified from literature and these factors were tested with the stakeholders of the construction industry in the study area to seek their opinion on these causes by way of ranking them based on relative importance index (RII)
The data were analyzed according to the research objectives i.e. to establish the causes of building failures and its impact in the construction industry
Summary
The main function of the construction industry is to provide infrastructure that protects the life of users and or occupants and contents from the weather, mainly rain, wind and extremes of temperature. It is most important to provide the basic needs which will achieve all of these functions. Features such as windows, pipes, air conditioning system and finishes are only additional. Construction failures and defects are common phenomena in construction industry and these have negative impacts towards cost, duration and resources of project. Failures and defects often cause unnecessary expenditure, deaths and project delays
