Assessing The Impact Of Delays On Cost Over runs On Building Construction Projects In Uganda. A Case Study in Kampala

Abstract

Delays in building construction projects are a persistent issue in Uganda’s construction industry, often leading to cost overruns and project inefficiencies. This study focuses on assessing the impact of project delays on cost overruns within building construction projects in Kampala. It investigates the causes of delays, the extent of their frequency and duration, their relationship with cost overruns, and the most affected cost components. A mixed-methods approach was employed, combining quantitative data from 60 professionals through structured questionnaires and qualitative insights from open-ended responses. Statistical analysis using descriptive and non-parametric tests, including the Kruskal-Wallis H test and Spearman’s rank correlation, was used to explore associations among variables and rank key factors. The findings revealed that inadequate financing and delayed payments were the most significant causes of delays, followed by material shortages and poor project planning. Delays were commonly reported to last 1-3 months and were prevalent across all project types, regardless of sector. A statistically significant relationship was found between the duration of delays and the level of cost overruns, indicating that longer delays tend to increase project costs. Labor costs, equipment rental, and project management expenses were the most affected cost components. The most frequently suggested mitigation strategies included thorough project planning, timely material procurement, adherence to schedules, adequate funding, and prompt supervision. These practical recommendations reflect industry professionals’ perspectives on minimizing the financial impacts of delays. The study concludes that effective delay management is essential to control cost overruns in construction projects. Addressing funding issues, improving planning practices, and enhancing stakeholder coordination are crucial for ensuring timely and cost-efficient project delivery in Uganda’s building sector.
