Quality Assurance Surveillance Report

i. Contract:B231" G. Liscum (PD)

2. Conducted By:J. Musser

5. Organization Under Surveillance:Tutor Saliba Perrini

7. Subject of Surveillance:CIC 5

3. Date:7/7/95

Page 1. of 14. ID No:95-65

6. Location:B231 Electrical Room 67

8. Individuals Contacted:Gary Mancher, Lead Inspector (PD)

9. Requirement Reference and Description:

Specification Section 16050 paragragh 1.3.C states states "Seismic Restraints- Equipment andinstallation of electrical material shall be as indicated, and shall conform to part II, Appendix A ofseimological Investigation and Design Cdteda.

Distribution: G.B. Morschauser (PD) J.J. Adams G. WarrenG. Eyzaguirre(PD) H. Priluck T. Lee C. DixonM.D. Latch C.W. Stark K. Morrow (PD) QA fileRMC

10. Surveillance Activity and Results:

A review of the project files revealed the required seismic calculations for the CIC cabinets aremissing from the project file. Seismic calculations for other equipment were spot checked. Thesewere also missing from the project files. Since calculations were not available, a comparison of thevarious CIC cabinets installations with other CIC cabinets were performed. On CIC-5 in room 67 thecontractor used angle iron with bolts connecting the angle iron to the cabinet leg and a anchor boltconnecting the angle iron to the floor. This is not in accordance with the other CIC cabinets whichused anchor bolts through the bolt holes in the base of the cabinets.

Recommendation:

1) Request copies of missing seismic calculations from the contractor to establish the approvedseismic installation requirement.

2) Vedfy Installed seismic anchorage for the CIC-5 cabinets are accordance with the approvedseismic calculations.

Conclusion:

Based on visual observations the present seismic installation for CIC 5 is not consistent with theother CIC cabinets within the station. Since the installation is not consistent with the other CICcabinets, CIC 5 needs further investigation. Additionally, seismic calculations are missing from theproject files which makes verification of this installation and other installations difficult. ResidentEngineer to follow-up to assure the installation by the contractor is in accordance with the seismiccalculation requirements.
