Project Planning Practices and Performance of Roads Construction Projects in Kenya

The purpose of this study was to investigate the influence of project planning practices on the performance of road construction projects in Kenya. Additionally, the study sought to determine the moderating effect of project monitoring on the relationship between project planning practices and project performance. Road construction projects in Kenya frequently encounter issues such as cost overruns (averaging 45%) and delays (up to 21 months), leading to poor performance. Despite the implementation of project planning practices, these challenges persist, affecting the overall quality and efficiency of road projects. The study adopted a positivist research philosophy and employed both cross-sectional survey and explanatory research designs. The target population included 62 contractors, 54 resident engineers, 60 quantity surveyors, 32 KURA officials, and 28 KENHA officials in Kenya. The sample size was determined using Slovin’s formula and selected through stratified random sampling. Data collection methods encompassed both primary data, gathered via structured questionnaires, and secondary data from the websites of the Kenya Urban Roads Authority (KURA) and Kenya National Highways Authority (KENHA). Qualitative data were analyzed thematically, while quantitative data were processed using descriptive and inferential statistics through SPSS version 25. Results were presented using tables, pie charts, and bar charts. The study found that project planning practices have a positive and significant effect on the performance of road construction projects in Kenya. Additionally, it revealed that project monitoring moderates the relationship between project planning practices and the performance of road construction projects. From a practical standpoint, the study emphasizes the need for structured planning, including stakeholder identification and clear project objectives, to enhance outcomes. From a policy perspective, the findings support mandating rigorous planning and monitoring frameworks to better equip project managers and enhance infrastructure development.
