Rework is the act of carrying out a work for the second time due to defect. It remains a chronic problem in the construction industry because of human imperfection. It is a menace in the Nigerian construction industry as it contributes to cost and overruns in project. It leads to clients’ and contractors’ dissatisfaction. The aim of this research is to study factors causing rework occurrence in ongoing building project and elements that can be influenced by it. It is a criteria-based research. The targeted population constituted 25 ongoing building projects, precisely commercial buildings. Data collection was carried out with the use of structured questionnaire and checklist for archival data. Data presentation was done using frequency table and bar charts while data were analyzed using relative importance index and T-test. The result of the analysis showed that the level of occurrence of rework in building elements varies. It was discovered that the main factors causing rework are poor workmanship, defective materials and incompetent supervision and elements mostly affected are Blockwork, Roof and plastering. Conclusively, the level of rework is one of the key determinants to project performance. Construction team all have crucial roles to play to the success of any project. Construction organizations should re-examine the way they conduct their operations, become technically oriented and become prevention-focused to help strive for better organizational management.
