An Analysis on Cost Over runs in Road Construction Projects: A case study of Lusaka District

Author(s) Pumulo Muchuu, Kelvin Chibomba
Country Zambia
Abstract Cost overruns in construction road contracts projects are a prevalent issue that hampers the successful and timely completion of infrastructure development. This study aims to analyze the factors contributing to cost overruns in road construction projects within Lusaka District, Zambia. By examining various projects and their associated cost overruns, this research identified key contributors, quantified their impact, and proposed mitigation strategies to enhance project cost management. The research employed a case study method approach, incorporating multiple sources of evidence including qualitative and quantitative to understand the scenarios. Interviews and surveys were conducted with project stakeholders, including contractors, project managers, and government officials, to gather primary data regarding project specifics and underlying causes of cost overruns. Additionally, a comprehensive review of project documentation and financial records was performed that provided quantitative insights into the extent of cost overruns. Understanding these factors would aid in the development of strategies to mitigate cost overruns, including improved project planning, risk assessment, stakeholder collaboration, and enhanced cost estimation methodologies.
Data gathered from respondents reflected that 7(7%) of the participants were aged between 21 - 30 years, 60 (60%) were aged between 31 - 40 years, 30 (30%) were aged between 41 - 50 years and 3 (3%) of the respondents were 51 years and above.
The study indicated that 5 (5%) of the participants attained certificate level of education, 15 (15%) of the participants attained Diploma level of education, 70 (70%) of the participants attained Undergraduate degree level of education and 10 (10%) attained Master’s level of education.
It was found that 75% of the respondents agreed that the use of CPM in project planning increased the efficiency of completion of the project while 25% of the respondents said that the use of CPM in project planning did not increase the efficiency of completion of the project. Ultimately, this research aims to contribute to the body of knowledge surrounding construction project management, particularly in the context of road infrastructure development, and offer actionable recommendations to optimize cost management and ensure the successful delivery of road projects in Lusaka District and beyond.
