APPENDIX C AREA WALK-BY CHECKLISTS (AWCs)C-1

[L ------ Paul C. Rizzo Associates, Inc.Sheet I of 123 StatusQ N U Area Walk-By Checklist (AWC)Room 105 Floor El. 545 Bldg.AUXB Instructions for Completing Checklist This checklist may be used to document the results of the Area Walk-By near one or more SWEL items. The space below each of the following questions may be used to record the results of judgments and findings.Additional space is provided at the end of this checklist for documenting other comments.1. Does anchorage of equipment in the area appear to be free of potentially adverse seismic conditions (if visible without necessarily opening cabinets)?

Anchorage for cover plate of E31-4 does not have nuts, see Photo 2.Concern has been judged not to represent an adverse coniditon regarding the component's seismic performance.

2. Does anchorage of equipment in the area appear to be free of significant degraded conditions?

3. Based on a visual inspection from the floor, do the cable/conduit raceways and HVAC ducting appear to be free of potentially adverse seismic conditions (e.g., condition of supports is adequate and fill conditions of cable trays appear to be inside acceptable limits)?4. Does it appear that the area is free of potentially adverse seismic spatial interactions with other equipment in the area (e.g., ceiling tiles and lighting)?
