ABSTRACT

The primary objective of asset/bridge management is ensuring safety of users while maintaining or reducing costs of ownership. Decision making tools are often used by bridge owners to assist in reaching these objectives and one such tool is life cycle analysis. In particular, the Bridge Life Cycle Cost Analysis (BLCCA) technique is extensively advocated in the infrastructure arena. But decision making capabilities can be enhanced by an accurate estimation of the benefits and life span of the structure. Thus, Bridge Life Cycle Analysis (BLCA) is a metric that requires consideration on all three components and includes BLCCA, BLCBA (Bridge Life Cycle Benefit Analysis) and BLSA (Bridge Life Span Analysis).
