{{#Wiki_filter:C Seismic Walkdown Checklists (SWCs)Below are the names and signatures of the personnel who performed the seismic walkdowns. Ben Frazier Kevin Gantz Mojtaba Oghbaei Craig Swanner James Wiggin?~ ~(.e~hMA~~%~JZg4 The order of the Seismic Walkdown Checklists (SWCs) for Unit 2 is shown in Table C-1 below and the order of the SWCs for Unit 0 (common) is shown in Table C-2.The "Anchorage Configuration Confirmation" column is described in Section 5.2.1 of this report. The last column in Tables C-1 and C-2 provides the corresponding Area Walk-By Checklist (AWC). (AWCs are included in Appendix D of this report.)
