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)?

Component composed of 7 sections.

Inspected two end sections at front and verified two plug welds -3/4" diameter.2. Is the anchorage free of bent, broken, missing or loose hardware?3. Is the anchorage free of corrosion that is more than mild surface oxidation?

4. Is the anchorage free of visible cracks in the concrete near the anchors?Base grout found in good condition.
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.)

Verification based on adequacy per SQUG calc C-CSS-FJ.SQUG calculations show anchorage to be adequate fom previous outlier resolution, page 9 of 28.6. Based on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?

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)?

2. Is the anchorage free of bent, broken, missing or loose hardware?Equipment found to be stitch welded to base.3. Is the anchorage free of corrosion that is more than mild surface oxidation?
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.)

Anchorage detail found to be consistent with the presented in SQUG calc C-CSS-K5-2.

16 -1 1/4" cast-in place bolts spaced around 5ft each.6. Based on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?
