Purpose It is generally accepted that organisational culture is capable of influencing how project organisation performs. It can also impact on how people set individual goals and objectives, perform their roles, tasks and deploy resources to achieve set objectives. The purpose of this paper is to examine the influence of organisational culture on the occurrence of rework in Nigerian construction industry. Design/methodology/approach The research adopted mixed method research using both quantitative and qualitative approaches to elicit information. Though, the result of the questionnaire survey was presented in this paper. Exploratory factor analysis was used to identify which variables measured attributes of the same underlying proportions, while descriptive statistics and multiple regression analysis were used to establish the influence of organisational culture on rework. Findings The study identifies 14 factors as causes of rework from the result of factor analysis. The outcome also indicates that leadership style, success criteria and management style are important organisational culture dimensions. Poor management practices and lack of teamwork are found to be largely responsible for poor project delivery due to rework occurrence. Practical/implications The research will be of significant benefit to both the academic and industry practitioners. The result of the research will provide academics with useful insights into the influence of organisational culture on project delivery by undertaking future research to inform better understanding. The research will also provide practitioners with good understanding of how culture within their organisations can influence the performance of their subordinates or employees. Further research is encouraged to investigate the influence of management and leadership style on project delivery in the context of Nigeria. Originality/value This study is the first attempt to investigate the influence of organisational culture on occurrence of rework empirically in the Nigerian construction industry. There is paucity of research focusing on this area as it affects project delivery.
