Determining the rational basis for setting the defects liability period on completed institutional buildings in Kampala

Abstract

The building and construction industry plays a vital role in the economy and is classified based on purpose. Defects liability period (DLP) is a common practice where the contractor is held accountable for defects. However, in Uganda, there is no specific legal provision regulating DLP. Defects are inevitable, and the DLP duration varies depending on the contract. This study aims to determine a rational basis for setting DLP on completed institutional buildings to improve managing DLP in the future. This study used a mixed-methods approach to identify common defects during the defects liability period in completed institutional building projects in Kampala. Data was collected through checklists, observations, and interviews, and analyzed using statistical processes and content analysis. The study population was a representative sample of 13 institutional building projects in their DLP. The study found that peeling off paint in walls was the most common defect during the defects liability period (DLP) of completed institutional building projects in Kampala. The analysis also showed a positive correlation between the DLP and the time duration of certain defects, suggesting that the DLP can be set by establishing the time duration of specific defects. The research findings provide a defects liability period model that can be used as a basis for setting the DLP providing adequate time to the contractor and client.
