Katy ISD Building Component Replacements​Athletic component replacements are items that have reached the end of their manufacturer lifecycle and include track resurfacing, bleacher replacement, roof repairs to Rhoads Stadium, and lighting updates. All building components have recommended life cycles and replacing those components at their lifecycle end, lowers total maintenance and repair costs, over time.

The components in the proposed Bond 2021 Building Components list represents our campuses and facilities' most critical replacement needs for the next three years.What are Building Component Life Cycles? All building components have recommended life cycles, or life spans. Manufactures, builders and contractor associations, as well as surveyors, measure, test and determine the life cycles of different building components. Extending a building component life cycle beyond its intended lifespan often leads to extended life cycle costs associated with correcting distresses needed to maintain components' minimal functional quality. Replacing building components at their lifecycle end, lowers total maintenance and repair costs, over time.
