Maintenance is an often overlooked aspect of appraisal of transport infrastructure projects. The effective treatment of maintenance within an appraisal is, however, fundamental to informing the decision regarding the optimum investment strategy. This is because the nature of the maintenance strategy can have direct implications on operating costs and other benefits (e.g. travel time savings). As such the impact of maintenance within an appraisal extends far beyond a simple consideration of its financial cost. This Note discusses the maintenance costs of transport infrastructure throughout the whole life-cycle, and how to incorporate it in economic evaluation.
