About this file
Appendix E is a comprehensive 26-page Quick Reference Guide to Component Life Cycle Estimates by Asset Type for the National Park Service. The document provides detailed lifecycle estimates for various infrastructure and system components, categorized into sections such as Roads, Parking Areas, Bridges, Tunnels, Water Systems, Wastewater Systems, Electrical Systems, HVAC, Communication Systems, and Special Structures. Each section includes specific items with corresponding estimated years of useful life, ranging from short-term components like pavement markings (3-7 years) to long-term infrastructure like concrete foundations and stone structures (40-100 years). The estimates cover a wide range of materials and systems, including wooden, metal, concrete, and specialized components across different types of facilities and environments.
