PR-2: Lifecycle Cost Analysis - points
Goal
Determine a pavement’s total life cycle cost for use as a decision making aid.
Requirements
Perform a life cycle cost analysis (LCCA) of the project’s pavement structure in accordance with the method described in the FHWA’s Interim Technical bulletin, Life-Cycle Cost Analysis in Pavement Design (1998). The LCCA should be done for all pavement alternatives being considered. For preservation projects where no alternative design can be reasonably considered, perform the LCCA on the selected design. This LCCA may be done manually or by using the FHWA’s RealCost software available for free at:
http://www.fhwa.dot.gov/infrastructure/asstmgmt/lccasoft.cfm. LCCAs that incorporate more than the pavement structure are addressed by MR-7.
Required Documentation
This requirement is typically satisfied during the planning process. Submit a link to or copy of agency policy on LCCA if one exists. Submit the report produced by the RealCost software. Include a short narrative describing which alternative was selected and the principal reasons for selecting it.
