The space below each of the following questions may be used to record the results ofjudgments and findings.

Additional space is provided at the end of this checklist for documenting other comments.Anchorage 1. Is the anchorage configuration verification required (i.e., is the item one of the 50% of SWEL items requiring such verification)?

Fan is mounted on four spring isolators supported by rod hangers.Rod hangers are attached to steel support structure, which is anchored to the Q-deck with four 3/8" diameter anchor bolts.2. Is the anchorage free of bent, broken, missing or loose hardware?No missing bolts identified associated with component supports.3. Is the anchorage free of corrosion that is more than mild surface oxidation?

None observed during inspection.

4. Is the anchorage free of visible cracks in the concrete near the anchors?5. Is the anchorage configuration consistent with plant documentation?(Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)

3/8" diameter anchor bolts supporting the fan support assembly are shown to be seismically adequate in Calculation C-CSS-73-1.
