A link exists between the level of investment in infrastructure and economic growth. However, it has been shown that in spite of huge amounts earmarked for infrastructural projects, the desired outcome/benefits are not attained in many cases. This has been attributed to poor adherence to project management principles in the conception, design, and execution of these projects. This paper highlights poor project conception and definition, poor budget and stakeholder management, as well as inadequate monitoring and evaluation as major causes of these failures. This can be minimized through the integration of good project management principles in the planning, design and execution of projects, supported by a robust monitoring and evaluation procedure.
