The analyst can switch back and forth between the two modes without any loss of data. So as to accommodate two types of analysis - relatively basic estimations of life-cycle cost and comprehensive life-cycle cost that include uncertainty and risk assessments - BridgeLCC 2.0 can operate in two alternate modes: (1) a Basic Mode where the amounts and timings of costs are best-guess values without any uncertainty, and (2) an Advanced Modewhere uncertainty in amounts and timings of costs can be taken into consideration. Analyses are carried out in discrete steps, which are now listed on the left side of the BridgeLCC Cost Summary Window (Figure 1). The software includes a cost classification scheme that helps insure that all costs are accounted for and are well organized so that useful comparisons can be made quickly between project alternatives. what are acceptable levels of cost risks associated with earthquakes, river flooding, or other disasters.īridgeLCC 2.0 uses an economic methodology based on the ASTM Standard Practice for measuring the life-cycle costs of buildings and building systems (E 917).whether to use a new construction material or process in a bridge design and.whether to repair an existing bridge or replace it.what bridge designs are life-cycle cost-effective.BridgeLCC 2.0 supports this effort by helping engineers to evaluate bridge-related design decisions, including The Office of Applied Economics develops economic methods and software to aid industry in evaluating the cost effectiveness of new-technology construction materials, 'green' building materials, building energy systems, and other construction/building processes.
