Project Cost Management Strategies and Performance of Water Projects in Nairobi City County, Kenya
Abstract
Despite significant initiatives aimed at improving water access in Nairobi City County, many communities continue to face challenges in obtaining clean and reliable water. Existing literature underscores the critical role of project cost management in the successful implementation of infrastructure projects. Therefore, a study investigating the influence of cost management strategies on the performance of water projects in Nairobi provides essential insights into the unique challenges and opportunities specific to this urban environment, while addressing existing gaps in understanding the relationship between cost management and project outcomes. This study focuses on specific objectives that assess the effects of financial resource allocation, financial monitoring and control, risk management, and procurement cost-saving strategies on water project performance. The study was grounded in Activity-Based Costing Theory, Agency Theory, Risk Management Theory, and Transaction Cost Economics Theory. A descriptive research design was adopted, targeting 100 employees from Engineering, Internal Audit and Risk, Supply Chain, Operation and Maintenance, and Finance departments. A census sampling approach was employed, and data was collected using a structured questionnaire. Pilot test results confirmed strong validity and reliability. Data was collected via structured questionnaires distributed physically and digitally to 100 Nairobi City County employees across five departments, with confidentiality assured to encourage honest responses. Data was analyzed using Statistical Package for Social Sciences (SPSS) version 29, employing descriptive and inferential statistics including frequencies, percentages, mean, standard deviation, correlation analysis, and multiple regression analysis. Descriptive statistics revealed below-neutral perceptions across all cost management strategies and water project performance. Multiple regression analysis indicated that the four strategies collectively explained 68.1% of the variance in water project performance (R² = 0.681, F = 45.126, p < 0.001). All four variables had significant positive effects: procurement cost-saving strategies had the strongest influence (β = 0.312, p = 0.002), followed by financial resource allocation (β = 0.287, p = 0.003), financial monitoring and control (β = 0.245, p = 0.007), and risk management cost strategies (β = 0.198, p = 0.034). All four null hypotheses were rejected. Qualitative findings revealed that respondents advocated for digital financial systems, stakeholder engagement, performance-based contracting, and capacity building. Key challenges included inadequate budgeting, delayed fund disbursements, procurement inefficiencies, and scope changes. The study concludes that financial resource allocation, financial monitoring and control, risk management cost, and procurement cost-saving strategies all significantly influence water project performance. The study recommends that Nairobi City County Government strengthen financial resource allocation through Activity-Based Costing, enhance financial monitoring via real-time tracking, invest in risk management frameworks, and promote procurement cost-saving strategies including competitive bidding and framework contracts.
Keywords: Financial resource, financial monitoring, risk management cost, procurement cost-saving, water project performance.
