For many component-sections, repair early in the lifecycle can extend life and avert expensive damage caused by accelerated degradation later. " Experience with the building component CI metric has shown that for a wide variety of components, the repair sweet spot falls in the CI equals 70-80 range. Performing repairs at the sweet spot can result in penalty cost savings from major repair or replacement due to costly critical failure consequences later in the lifecycle. Reliability and Condition Each building constituent component-section has a finite service life.

In general, condition and reliability are related as follows: • Condition and reliability are maximum ( 100) at or near the start of the service life, • Condition and reliability approach the minimum state (0) asymptotically, • Condition and reliability deteriorate unless corrective action is performed, and • As condition deteriorates, reliability likewise decreases. Condition Prediction Model Requirements • • • In order to have a robust condition prediction model, the following methodologies are proposed: Model is seeded with reasonable initial assumptions, and "self-corrects" based on collected information, Model automatically adjusts the expected service life based on an inspection generated condition index, Model takes into account the inspection date and type when calibrating the prediction trend, 22 AATT 2006 • • When repair work is completed, model adjusts the prediction trend, and Model takes the type of repair work into account when projecting the predicted condition trend.
