Life-Cycle Cost Analysis

Life-cycle cost analysis (LCCA) examines the total cost of ownership for infrastructure assets over their entire lifespan. Researchers in this area investigate methods for estimating initial construction costs, ongoing maintenance and repair expenses, operational expenditures, and eventual decommissioning or replacement costs. This involves developing and applying models that account for factors such as material degradation, inflation, discount rates, and uncertainty in future costs. The research also explores the integration of sustainability metrics and risk assessment into LCCA frameworks to inform more resilient and cost-effective infrastructure investment decisions.

This research holds particular relevance for Arkansas, a state with significant transportation infrastructure needs and a strong agricultural and manufacturing base. LCCA can help state agencies and local governments optimize investments in roads, bridges, and other public works, ensuring long-term value for taxpayers and facilitating economic development. Understanding the full cost implications of infrastructure choices also supports sustainable resource management and can inform planning for the state's growing population and evolving industrial landscape.

Interdisciplinary connections are central to LCCA research, drawing upon expertise in pavement engineering, structural materials science, construction materials analysis, and transportation infrastructure planning. This work benefits from collaborations across institutions to address complex infrastructure challenges.
