Life Cycle Cost Analyses of Dayboard Systems

This report presents life cycle cost analyses on 13 possible dayboard systems. A dayboard system consists of the combination of backing, adhesive, and properly colored substrate necessary to construct navigational signs for the U. S. Coast Guards aids-to-navigation system. Total dayboard construction costs are estimated for each system. These costs - combined with maintenance and repair costs - are projected for a 10 year period 1992-2001 assuming a 10 discount factor. Net present values NPV of each system are compared and range from 3.0M to 9.7M. The present systems NPV is 6.1M. Considering only construction costs, potential savings of a long life dayboard range from 150, 000 to 580,000 per year. Supporting cost data and detailed cost calculations are included for each system in the Appendix. The results of these analyses - together with information from a separate technical evaluation of dayboard materials - will aid in selecting the most cost effective dayboard system for the U.S. Coast Guard.
