Instructions for Completing Checklist This checklist may be used to document the results of the Seismic Walkdown of an item of equipment on the SWEL. 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.Anchoragel. Is the anchorage configuration verification required (i.e., is the item oneof the 50Yo of SWEL items requiring such verification)?This is an 8 section MCC, but it is in-line with two other MCC sections (MCC FI4 and MCC FI5).It was verified that all adjacent sections are bolted together. Each section of MCC is welded to embed channels at front and back with an average of at least 5" long, 3/16" fillet welds.Y 2. Is the anchorage free of bent, broken, missing or loose hardware?

No degraded conditions foundfor base stitch welds.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?No craclrs identffied in sloped grout at mounting base.5. Is the anchorage configuration consistent with plant documentation?(Note: This question only applies if the item is one of the SOYo forwhich an anchorage configuration verification is required.)

SQUG Calculation C-CSS-Fl24 provides qualification of as-installed welded anchorage.

6. Based on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?

This 8 section MCC is adjacent to MCC FI4 and MCC F15. These MCCs were opened and inspected. It was verified that these MCCs are bolted together. At the south end of this MCC, there is a I .5" gap to panel CDF I 2A- I , which is iudged acceptable to preclude pounding.Evaluated bv:
