The purpose of this paper was to assess the magnitude of the impact of construction-related rework on selected project budgets and schedule in public building construction in Uganda. The magnitude of construction-related rework was the mean determined over construction contracts under a selected project and expressed as a percentage of the construction contract sum.
A single case multi-unit study approach was adopted. A case study protocol was prepared that included a checklist, observation schedules and an interview guide. The three instruments were used to collect data from building contractors and end-users (the teaching staff and medical assistants). Representatives of the client entity and the end-users provided sufficient project documentation and related supplementary information for the study.
Construction-related rework was predominantly attributable to design information omissions, unacceptable workmanship and inadequate supervision of the contractor. Lightning conductor, electrical and roofing installations were the building elements that had the highest frequency of rework. It was further determined that the mean percentage of rework related impact on project budget and schedule was approximately 4.53 and 8.42 per cent, respectively.
The findings inform policy makers about likely areas that contribute to significant wastage and value loss in quality management of public sector projects. The research advocates for improved data collection protocols, integration of adequate design management and a whole life value philosophy during the public building construction process.
