RESIDENTIAL BUILDING COLLAPSE IN NIGERIA; CAUSES, EFFECTS AND SOLUTION

The research investigated the causes and consequence of building collapse in Nigeria using historical data from 1974 to 2009 and also proffers appropriate solutions. Relevant books, seminar papers, workshop papers, articles, etc. were reviewed so as to examine the general view of individuals that have worked on similar study. Data for the study were obtained through historical data of past building collapse in Nigeria. The data were presented and analyzed using tables, percentile, Pearson moment correlation coefficient (r) and linear regression analysis to generate a model. Seventy (70) buildings that collapsed in the country were gathered, upon which the analysis was carried out. The study revealed that poor maintenance culture, design error, poor quality of materials and workmanship, natural phenomenon and excessive loading contributed to about 7%, 13%, 53%, 7%, and 20% respectively ofbuilding collapse in Nigeria with most of them being private residential buildings executed by indigenous contractors. The study finally recommended that Standard Organization of Nigeria (SON) should increase their effort in sanitizing building materials in the market. More so, professional bodies in building industry should ensure proper supervision of workmen and efficient checking of materials before incorporation into building works.
