Cost Management Practices and Performance of Roads Construction Projects in Kenya

Purpose: The purpose of this study was to investigate the influence of cost management practices on the performance of roads construction projects in Kenya. The study also sought to determine the moderating effect of project monitoring on the relationship between cost management practices and performance of construction projects in Kenya. Statement of the Problem: Road construction projects in Kenya often experience significant challenges, including cost overruns averaging 45% and delays of up to 21 months. Despite the use of cost management practices, project performance remains poor, with issues of delays and quality persisting. Methodology: The study utilized a positivist research philosophy and employed both cross-sectional survey and explanatory research designs. The target population comprised 62 contractors, 54 resident engineers, 60 quantity surveyors, 32 KURA officials, and 28 KENHA officials in the Nairobi Region. Sample size was determined using Slovin’s formula and selected through stratified random sampling. Data collection included both primary data via structured questionnaires and secondary data from the websites of the Kenya Urban Roads Authority and Kenya National Highways Authority. Qualitative data were analyzed thematically, while quantitative data were processed using descriptive and inferential statistics with SPSS version 25. Results were presented using tables, pie charts, and bar charts. Findings: The study found that cost management practices have a positive and significant effect on the performance of road construction projects in Kenya. The study also found that project monitoring has a moderating effect on the relationship between cost management practices and performance of road construction projects in Kenya. Unique contribution to theory, practice and policy: This study contributes uniquely to the theory by enhancing the understanding of how specific cost management practices influence the performance of road construction projects in Kenya, integrating the role of project monitoring as a moderating factor. Practically, it offers actionable insights for project managers and stakeholders on the importance of robust cost management frameworks to improve project outcomes. Additionally, the findings inform policymakers about the necessity of establishing regulations that support effective cost management and monitoring systems, thereby fostering better performance in road construction initiatives across the country
