Abstract
Life cycle cost analysis (LCCA) is a critical decision-support tool in infrastructure project planning, enabling stakeholders to evaluate total cost of ownership over the asset’s lifespan. This manuscript presents a structured study of LCCA methodologies applied to infrastructure projects up to 2013. The abstracted framework encompasses cost identification, discounting techniques, sensitivity analysis, and risk considerations aligned with engineering practices of the period. A statistical evaluation of cost components across five case studies is provided via a summary table. Results highlight the dominance of maintenance and rehabilitation costs in long-term expenditures, and methodological variations affecting present worth calculations. Identified research gaps include standardized treatment of uncertainty, integration with sustainability metrics, and lifecycle risk modeling. Ten key references published by or before 2013 are cited to ground the analysis in contemporaneous technology and theory.
