PAGE 1 0F 1 Mr. -Taylor called and stated that Mr. Tapia had some questions regarding the concrete placement he observed on Friday, January 13, 1978. Mr. Tapia then asked

~

.

a the following questions:

- What vere the physical dimensions of the placement?

- What vere the quantities of admixtures utilized in the concrete?

C Please verify that 35 F0 was the ambient temperature recorded on the QC

- Inspection boo 'I What were the slump and air content measured on the first test load for

,

this placement? (This is the test load which was h60)

, 7 I then asked Mr. Tapia hov long he observed the placement. He stated that he

' was present for approximately 20 minute !i I asked hi= if he actually observed improperly vibrated concrete buried in the

,

C! placement. He said no, and then clarified his description of the improper practices

. he saw. He stated that on two placements he witnessed vibration beneath the tremis, i

but no vibration in areas between tremis. He was not specific about the size of this

'

area. He further stated that the underlying cause for the infraction was the improper answer given to him by the QC Inspector regarding spacing of vibrator insertion I also indicated B&R's position that we vere not in cold weather at the time in question. He stated that he believed that the ACI definition vould apply. I informed him that we had placed a stop work on concrete placement activities and he ackncv-

DISCUSSION i There were three basic concerns expressed by the NRC: i f: Concern regarding low morale of Civil inspectors _ .

and supervisor _

{

B. Alleged weakness of implementation relative to the onsite Civil QC progra .

" * Adequacy in staffing level of QC people in light of _

-

increased construction progress (personnel numbers) .

(NRC observation, not allegation) i

i Morale 1 l

1. Notice a very strong dissention between a QA/QC inspector [

and his supervisor. Negative comment ;

- . QA/QC inspector feels like a second class citize ;

(Example: Gang-box not equal to construction)

3. Complaint by Civil QC inspectors that comments (speci-fically nonconformance reports) aren't acted on. (hhen e asked for a specific example, no example was given).

__)- [ Comment that Civil QC inspectors were not given adequate  !

training in the new criteria / procedures, j

~~

l QA/QC (Civil) was not given opportunity to co : ment on l revision of procedure . QA/QC (Civil) was too busy--too much work to properly prepare for inspection ,

. Imolementation of Site Civil.QA/QC Activities

Procedure CCC-P requires three levels of field inspection be satisfied prior to the placement of concrete. It was felt on the part of the QA/QC inspectors that Field Engineers and Craft Foremen are not doing an adequate job. This results -

in an inordinately long punch-lis , ! Specific example (cited by the NRC) reinforces the abov .

An example rebar was left out, and was subsequently caught by b

  • Staffing  ; i 9 Staffing level is 140 B6R QA/QC personnel of the l 4400 total work force, which is 21 short for the projected i B6R QA/QC staffing leve [

The NRC reviewed the South Texas Project enforcement history resulting in the following: ,

Twelve citations to date, seven of which are for violations of  !

CONCLUSIONS BY NRC i There is a QA/QC inspector morale problem on this job, !

which can adversely affect the overall jo i

, Long punch-lists are evidence that the up-front work is not actually being done properl .

' NRC has not observed QA/QC inspectors at a desk .
