The excavation and the reinforcing steel for the deadman and tieback system was completed and the placement of concrete including the mudmat was made.
Pier-W10:
The pier remained on active jacking throughout the week -
g SWPS: No work was performed at this structure during this week because of the Stop Work Order and nonconformance restrictions in effect.
BWSTi A concrete mudmat was placed around the existing foundation at the west tank.
Remov.al of laitance from the existing concrete surface by sandblasting continued. The grouting of the shear connection bolts continued.
i UAT:
The preparatory work inside of the UATs prior to cutting through the pipe l
continued.
Quality Control Documentation and Records Reviewed the effectiveness of Quality Action Requests ( QAR ) as a mechanism for addressing quality concerns.
Witnessed that Quality Inspections being performed for concrete placement.
Observations Construction:
The placement of concrete for the deadman and tieback was accomplished in a very organized and efficient manner. Due to the constraints placed on construction by the sequencing requirements, a very limited amount
[
of work could be performed on the Auxiliary Building underpinning until such time as the deadman concrete attains required strength. Although pre-assembly of the load transfer frame assemblies was made in the field prior to instal-lation at Piers E/W8, problems were encountered during installation due to tolerances. Resolution of these problems await an Engineering review and decision.
Additional Work Activity Packages were approved the latter part of the week
}
and will permit work in other areas to commence upen completion of load transfer at Pier E/W8.
Due to the grouting problems experienced while grouting the lower levelling plates for Piers E/WB, procedural changes have been implemented to resolve the problems with voids.
On July 26, and 27,1983, Mr. R. T. Kuesel, Chairman of the Board of Parsons Brinckerhoff, and Mr. S. C. Rossier, Assistant Engineering Manager of Stone &
Webster Engineering Corporation visited the jobsite.
After touring the site, Mr. Kuesel and Mr. Rossier indicated that all work areas were well organized and the anderpinning work viewed was of a very high quality, well above the industry norm.
They further noted that the welding for the grillage beams and Joad transfer frames that were examined in the storage area was of excellent quality and, again, above that normally seen in underpinning operations.

J. O. No. 14358 3
- Midland Plant Units 1 & 2 Independent Assessment of Underpinning Quality Control. Documentation and Records:
1.)
In reviewing the effectiveness of the QAR system the Assessment Team determined that MPQAD had, on occasion, used an extreme intrepretation of th_e term " indeterminate " to justify the issuance of NCRs.
In-these cases the NCRs were written primarily to obtain an expeditious re'sponse te. requests for additional information from Project Engineering. When FSO has elected to rework the nonconforming items, Project Engineering response is not required, thus the original purpost of issuing the NCR is thwarted.
The Assessment Team believes that request for additional information would more appropriately be handled through use of the QAR system. However, there are several shortcomings of the QAR system as it is presently used:
a.
QARs are only being written by QA.
Quality Control has a first-hand knowledge or concerns and should be able to originate a QAR.
b.
QARs may not fully alert Project Engineering to possible impact on given work activity.
The QAR system is too cumbersome for use in obtaining information when time is of the essence.
c.
QARs are not routed to FSO, consequently, FSO may not be aware of the Concern.
The Assessment Team believes that MPQAD should carefully consider modifying the existing QAR system or developing a new system for use in requesting information on Engineering requirements instead of relying on NCRs for this purpose. However, care must be exercised to insure that the system is not applied to truly nonconforming items.
It snould also provide a mechanism to stop affected work until resolution is obtained.
This latter requirement allows for the situation where a noncon-formance is suspected but unproven, thus requiring additional Engineering input and/or testing and inspection.
2.)
Observed US Testing' Laboratory personnel perform sampling and testing of concrete during concrete placement for deadman and tiebacks on west side.
Testing and sampling was done in accordance to project procedures.
Work Activity Packages - An overview was performed on Work Activity Packages WAP 45,49 and 52.
All questions and comments were satisfactorily answered.
These work activity packages were found to include sufficient information to complete the work described.

Parish Purpose This meeting is held each day to discuss items regarding the Independent Soils Assessment at the Midland Plant, Units 1 & 2.
Discussion Item 45 Status of Piers E/W8 Lower Leveling Plate Grouting.
J.
Fisher reported that portions of the lower leveling plates had been regrouted after void areas had been detected. Efforts are enderway to avoid these installation problems in the future by increasing the size of the batching equipment and considering the introduction of bleed holes in the plates to allow air to escape during the placement.
The Assessment Team agrees that procedural modifications are required to improve the installation quality. ( CLOSED ITEM )
l Item 45 Rebar Threading NCR on E/W8 Grillage Tiebacks.
J.
Fisher reported that the nonconformance on the reinfcrcing bar threading i
procedure requirements has not been resolved. Resolution is required in order j
to fully complete the deadman and drop-pit tieback installations. ( CLOSED ITEM) l Item h5 Status of Pier E/W8 Load Transfer.
J.
Fisher reported that the pier load transfer would be likely toward the end of the week depending upon the leveling plate grout cure and resolution of fabrication nonconformances on jackstands.
( CLOSED ITEM )
Item 45 4 - Status of Service Waterline Excavation.
J.
Fisher reported the FSK for support of the electrical duct is in QA review.
Resumption of the work is curtailed by release of this field sketch.
( CLOSED ITEM )
Ithm45 QC Hold Tag Descriptions.
W.? Kilker observed that over the past 1 - 2 weeks the descriptiij portion of the Hold Tag has generally been a generic statement on preventing inaccessibility of I
the item to occur.
The exact nature of the respective nonconfordince has been found on attached forms.
W.
Kilker questioned if that was the intent of the I
recent change to the MPQAD tagging instructions.
It was suggested the item being discussed in the weekly MPCAD/ Assessment Team meeting.

It_em 45 Unit 1 EPA Settlement.
J.#
Fisher and E.
Cviki reported that the settlement rate of the EPA ( west-side ) has reduced markedly over the past few days.
The liklihood now is quite small of reaching the alert level before grillage installation is completed.
l Nevertheless, Mergentime has been notified to prepare the equipment to install temporary supports, if required.
( CLOSED ITEM )
Item 45 Approval of Superplasticized Concrete Mix.
G.
Murray said the informstion on the proposed mix designs hac been forwarded to the NRC and discussions are underway.
P.

Item 45 Lagging Lower Backpacking.
J.
Fisher, in response to an outstanding open item, stated that it is the intent of the Contractor to minimize the amount of backpacking material left between lagging sets once the backpacking operation is completed in a given area. ( CLOSES OUT ITEM S of Daily Meeting Notes of April t, Weekly Report # 29 and Item 44-31 )
Item 45-11 QA Programmatic Procedural Changes.
In response to an outstanding open item, R.
Sevo verified that the necessary programmatic retraining and PQCI re-write was accomplished prior to the field
- use of the applicable documents ( CLOSES OUT ITEM 1 of the Daily Meeting Notes t-of May 26, Weekly Report # 36 )
Item 45 Load Transfer Acceptance Criteria.
E.L: Cvik1 and M.
Lewis, in response to an cutstanding open item, stated that se{tlement data used to determine the acceptance criteria for wedging-off the pier load will be based on settlement that occurs after rebound 7dring the 125 percent to 110 percent jack load decrease. The Assessment Team agreed that this' approach was acceptable.

DeWitt Purpose This meeting is held each week to obtain information from MPQAD regarding the Soils Underpinning work at the Midland Plant Units 1 & 2.
Discussion Item 45 Status of NIR f.13 D.
Horn stated the PQCI is in the process of being revised.
Once_the revision is complete the NIR can be closed. ( OPEN ITEM )
Item 45. Status of Receipt Inspection of N.P.S. Materials.
MPQAD understands that the inspections are complete.
However, the inspection reports and any nonconformance reports have not yet been completed. ( CLOSED ITEM )
Item 45 Construction Related QA NCR's.
J.
Meisenheimer stated that there was an area of concern with work performed by Bechtel direct hire personnel. ( BOP ) for Underpinning.
The concern arose as the result of the lack of procedural requirements for Quality inspection.
- However, there may be some misinterpretations of the C.A. requirements.
This area of concern was discussed with SMO and FSO. The CPCo, Q.A. manager will be on site to provide a class on the intent of the MPQP-2 requirements for prccedures for Bechtel work activities.
J.
Meisenheimer has instructed his staff to do a more thorough review of the Work Packages and has so informed FSO.
In addition, he has requested that QA be present at the FSO daily meeting which is conducted with the Field Supervisors to go over the daily activities.
J.
Meisenheimer indicated that this is not a widespread concern in that the electrical, instrumentation and FIVP work activities have been performed to the project requirements.
( CLOSED ITEM )
Item 45 40 - Status of The Two StopJiork Orders.
'J.
Meisenheimer stated that for the BWST, the BOP, PQCI should be out today. At that_ time the impact on the need for retraining and recertification will be evaluated.
For lhe SWPS a checklist on commitments has been developed and evaluated for comp}iance. The PQCI's have been developed, retraining and wnere _r_equired,re-examin-atiopisin-progress.
( CLOSED ITEM )
Item 45 Status of U. S. Testing.
}-[
M.
DeWitt stated that two NCR's and one QAR have been issued. One-NCR dealt with U. S. Testing timely notification for Q. C. witness points.
The second NCR dealt with U.S. Testing not having personnel certified to sample the stockpile and split-ting of these samples. It was pointed out that the Q.C. over-inspection has shown the U.S. Testing personnel do adhere to the procedures. ( CLOSED ITEM )
2 Notes of MPQAD Meeting Indepe,ndent Assessment of Underpinning Midland, Plant Units 1 & 2 Held at Midland Site Location Midland, M!chigan July 26, 1983 The..QAR was written to clarify the intent of U. S. Testing QA progi'am with respect to tensile testing of rebar.
The procedure implies that a certified Level I is to assi'st a Level II in performing the test. This appears to be more stringent than the ANSI definition of capabilities for Level I vs. Level II. ( CLOSED ITEM )
Item 45 Extent of Descriptions Included on Hold Tags.
W.
Kilker asked whether sufficient descriptive data was being included on Hold Tags.
J.
Meisenheimer stated that Hold Tags are a " flag " to identify a noncon-forming item to all Field personnel.
The mechanism for controlling the nonconforming item is the Nonconformance Report and the Conditional Release Report.
Too much information on the Hold Tags could be misleading.
This explanation was acceptable to S & W.
( C'OSED ITEM )
Item 45 Status of QA NCR On QC Certification.
B.
Holsinger asked for the status of the recent NCR's on QC inspector's certification.
J.
Meisenheimer stated that MPQAD is cognizant of the need for corrective action to assure that in every case the QC inspector is properly certified to the PQCI being utilized.
J.
Meisenheimer will provide a status next week. ( OPEN ITEM )
Item 45 Discussion on Mechanism of Identifying Quality Concerns.
B.
Holsinger stated that in the process of the recent grouting and regrouting of the E/WB lower leveling plates ( see Assessment Team Daily Meeting Notes Items 44-5, 44-25 and 45-1 )
the QC inspector had identified a potential concern that there were no specific acceptance criteria. As a result, an NCR was written to require an engineering action to resolve the concern.
However, it must be realized that there can be very subtle differences between items being nonconforming due to an indeterminate condition and those that are indeterminate quality / engineering requirements.
B.
