Assessment of Quality Management Practices and Building Collapse in Osogbo, Osun State, Nigeria

Abstract

The study assessed the quality management practices as they affect building projects in Osogbo, Osun State, Nigeria, with a view to determining the causes of building failure. The work involved the distribution of questionnaires and a follow-up study on respondents. The questionnaires were designed to extract information from stakeholders: professionals from the Ministry of Works and Housing, contractors, and direct users of the projects on the general causes of building collapse in relation to quality management.To have a good representation of the study area, one hundred and twenty (120) copies of the questionnaire were administered using the Taro Yamani method of sample size determination. A total of 92 questionnaires were retrieved, and the results were subjected to descriptive and inferential statistical analysis.The study revealed that handling of the construction process by unqualified personnel and quacks, possession of approved drawings without compliance, and the use of substandard building materials were the major causes of building collapse.It was recommended that there should be constant evaluation of contractors and other players to determine their level of compliance with quality standards as prescribed by the regulatory bodies, in order to curb the incidences of building collapse.
