Examining Effectiveness of Cost Control Measures in Road Construction Projects: A Case Study of Road Constructions Projects in Lusaka

Construction practice has undergone a great deal of development in response to the dynamic nature of human needs and infrastructure. The main aim of the study is to examine effectiveness of cost control techniques used in construction projects. A case study of road construction projects in Lusaka. Specific Objectives included; establishing cost control technique used by contractors in construction projects, examining effectiveness of cost control technique used by contractors in construction projects, evaluating relationship between cost control and project completion and identifying limitations encountered by contractors in managing construction project cost. Research design is defined as the general plan of how the researcher goes about answering the research questions (Saunders et al, 2007). A descriptive case study approach was adopted to match the nature of the topic. The study used closd ended questionnaires and guided oral interviews. The sample size refers to the number of elements or units that the researcher draws from the population of respondents for research exercise. In this study, the sample size of 100 respondents were picked. And all 100 questionnaires were distributed. The main instruments used were questionnaires and personal interviews. The questionnaires comprised closed and open-ended questions. Questionnaires were administered or handed out to the respondents depending on their business operating schedules. Qualitative and quantitative data analysis was done. Quantitative data was used because it is easier to present using tables and qualitative data helped express the data collected. Data analysis is the process of editing and reducing accumulated data to a manageable size, developing summaries, looking for patterns and applying statistical techniques The data collected was analyzed using tables, figures. The researcher used both qualitative and quantitative method. For the qualitative data, the researcher used descriptive method, while for quantitative data will be analyzed using Microsoft Word and Excel to generate tables and other graphic illustrations. The data show that 41.7% of respondents find cost estimation "very effective," demonstrating strong confidence in its ability to accurately predict project costs and manage budgets. Another 33.3% rate it as "effective," indicating that a significant portion of contractors acknowledges its substantial benefits. Meanwhile, 16.7% consider it "somewhat effective," suggesting there is room for improvement or better implementation practices. Only 8.3% find it "not effective," highlighting that a minority faces challenges with current cost estimation methods. The study found that project teams do not effectively monitor and track project expenditures against the budget. To address this issue, it is recommended to implement a robust financial monitoring system that provides real-time tracking of project expenditures. This system should include automated alerts for budget variances, detailed expenditure reports, and regular reconciliation processes. Establishing a dedicated financial oversight team to review expenditures and ensure alignment with the budget can also help in maintaining financial control and preventing cost overruns.
