Bridge Life Cycle Cost Analysis

From Wikipedia, the free encyclopedia

Bridge Life-Cycle Cost Analysis (BLCCA), which is focus on the analysis of individual bridges, typically designates a planning or time horizon as the period of time over which all costs are to be estimated.

Transportation officials consider life-cycle cost analysis an important techniques for assisting with investment decisions.

The calculation of life-cycle costs depends on the choice of a distinct time period (planning time horizon) over which operations and maintenance costs are accrued, discounted (NPV), and compared with cost of capital.
