Presentation - Life Cycle Cost Analysis (LCCA) is an analytical framework to assess the most economically prudent investment from a set of alternatives over their respective lifetimes. Despite its merits, a recent survey prepared for the Federal Highway Administration (FHWA) highlighted that highway officials prioritize structural and functional conditions as well as initial costs over life-cycle costs. The goal of this research, is to identify which parameters are of key importance when conducting a probabilistic LCCA across a range of possible scenario. A detailed model is developed model is developed and applied to a range of scenarios which vary in terms of location, traffic conditions, design life, analysis period, and maintenance schedule to characterize their implication to the problem at hand and identify which parameters are consistently the drivers of
variation across the explored scenario space.
