BridgeLCC 1.0 Users Manual. Life-Cycle Costing Software for Preliminary Bridge Design.



M A. Ehlen


BridgeLCC (beta) is user-friendly software developed by the National Institute of Standards and Technology to help bridge designers determine the cost effectiveness of new, alternative construction materials. The software uses a life-cycle costing methodology based on the ASTM standard for life-cycle costing (E 917) and a cost classification scheme developed by NIST. This user manual describes the functions and settings in BridgeLCC and includes an example study which illustrates the use of the software. BridgeLCC is designed to run on Windows 3.x, Windows 95/98, and Windows NT 4.0. Although BridgeLCC is specifically tailored to highway bridges, it can be easily applied to pavements, piers, and other civil infrastructure.
