Decisions about the economic viability of a 100-year old school in Delaware depended on accurate estimates of current and future M&R funding requirements. Current M&R requirements were estimated with a conventional facility assessment, and also estimated using the Whitestone MARS life cycle cost model. The difference between the two estimates was less than 10 percent, demonstrating that a life cycle model can be a cost-effective alternative to physical inspection for estimating deferred maintenance. The same model showed that future M&R costs for the historic school would average almost 40% higher than those of a new school.
