No activity.
Piers W9/11:
Construction of the 6 x 6ft. access pit from El. 609 to E1.600 was completed.
The excavated material consisted of up to a 1 ft. thickness of unreinforced concrete underlain by sand and clay fill. The excavation was braced with wood lagging as the work progressed. Backpacking with sand was done as required and excelsior was placed between lagging boards. No groundwater was encountered. The lagging technique and materials were sim-l ular to those employed in constructing the access pits to piers E/W12 (Refer to Assessment Team Weekly Report Nos.13 and 14).
Pier E12: The Subcontractor installed lower leveling plate on the pier. Dry-pack grout was then placed in the spaces between the lower leve{ing plate and the pier,and the upper leveling plate and the turbine building m(t.
Piers E9/11:
The construction of the access pit progressed from El. 609 to El. 603 The excavated material consisted of up to 2 ft. of unreinforced concrete underlain by sand fill. The work was done in a manner simular to that described above for piers W9/11 access pit. No groundwater was en-countered.

-lBy Sestor Level Management Review Team February 2.'1983 On February 2,1983 the members of the Senior Level Management jteview Team for the independent assessment of the Auxiliary Building Underpinning visited i-the site. The Mgpagement Review Team consisted of:
t-J. P. Allen III N. B. Cleveland
.J.
R. Hall, Jr.
E. A. Long G. M. Schierberg L. Silano (Parsons Brinckerhoff, Michigan, Inc.)
~ Activities In preparation for our visit to the soils remedial area we were given a short course on " Confined Space Traiaing" by Consumers Power Company (CPCo) staff.
~
The Management Team was given a presentation on the underpinning work by J. Fisher of Bechtel Power ':orporation. We were then escorted on a tour of the site with emphasis on all the soils remedial work and a full account of the
- instrumentation program and crack monitoring being done by Wiss, Jenny, Elstener & Associates.
At exactly 11:00 A.M. members of the team were at access shafts to piers E-12 and W-12 where we had the opportunity to inspect the two piers. Pier W-12 excation was completed. Only the bell remained to be excavated on Pier E-12.
After lunch, some of the members of the team visited the pier and bell mock-up at the Poseville Yard and CPCo used a small scale model to further describe the Auxiliary Building Underpinning. Each stage of the underpinning for the Feedwater Isolation Valve Pit,.the Electrical Penetration Area and the Control Tower power portions of the Auxiliary Building were adequately explained by the CPCo engineers and the Stone & Webster - Parsons Brinckerhoff Assessment i
l Team. There was sufffeient time for many questions and these were answered l
satisfactorily for tia: Management Team.
The.IndependentAssessmentTeamdescribedtheirscopeofwork$ndtheir day-to-day operations. The reporting mechanism was discussed Ahd the four
--Nonconformanco Identification Reports issued t'o-date were described.
Conclusions i
In general, the overall underpinning operation is well organized. Progress, although slow initially, has been gaining momentum and is anticipated to accelerate. The instrumentation program is very satisfactory. Plotting

1.
E. Cvik1-stated that NIR f5 resolution is being discussed with the Team.
In the meantime, as soon as Project Engineering makes available the mix design trial mixes will be prepared.
2.
J. Fisher said a mock-up session on load transfer will be held today at i
the Merg' ntime's Mechanical Shop.
Later a load transfer mock-up with e
the jack stand in-place will be held at pier W12 prior to actual load transfer.
3 W. Kilker stated the Team witnessed several increments of the Unit.No. 2 FIVF proorload jacking en February 19-including the initial loading, full load and load release. The activity was well-planned and sucessfully accomplished.
4.
.A. Scott requested clarification on the requirements for washers and plates for steel lagging bolting.
E. Cviki is coordinating response with Project Engineering..
5.
A._ Scott requested clarification on requirements for concrete sampling during placement in terms of back of truck or end of the pump line.
E. Cvikl will resolve.

i 1.
E.-Cvikl aavised that trial mixes for concrete will begin February 28, 1983 B. Holsinger described the Assessment Team response to the proposed re-soluilon to NIR #5. Specifically, the proposal was to perform 3 point j
trial mixes for the regular concrete six and 1 point for the plasticized concrete mix.
The Team agreed this was an adequate proposal but cautioned that in the future making " upward" mix adjustments could be difficult.

2.
J. Fisher informed the group that jack-stand fabrication was delayed pend-L ing the resolution of a non-conformance on the milled surface quality.
3 W. Kilker requested access to the FSO training records and matrix.
J. Fisher stated 1R. Bradford and R. Groshong were responsible for that area.
W. Kilker l
will follow-up.
4.
B. Holsinger_ inquired about the inspection of instrumentation installations.
R. Oliver will furnish required documents and information.
5 V. Madill questioned the adequacy of the load transfer acceptance criteria of gauge monitoring "at least once per 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />."
J. Fisher will respond.
1 6.
V. Madill asked if a " slight drop" in the pressure reading might not be a better_way to recognize effectiveness of wedge tightening rather than listening for a " ringing" sound from hammering.
7.
E. Cvik1 stated that AISC 8th Edition requires the use of washers or plates on allslotted holes.
In this regard will pursue with Project Engineering the need for washers / plates on non-spreader sets of lagging.

B. Holsinger questioned paragraph 9.3 5 of the Mergentine ProceduIre MCP 19.000,._
Revision 9 as to the method of identification of primary tensile stress so that welders. and inspectors would know when this condition was applicable for weld undercut.
5 D. Lavelle informed the group of the sequence-of work forthcoming 4s. based on the ability of MPQAD to cover the work. The work schedule was based on the need of fabrication of drift sets and lagging which require inspection to the 1980 AWS code.

Reference L. Roune's question on Procedure MCP 16.000, Rebar Splicing Procedure, E. Cviki stated that procedure will not be tied to the ASME code for inspection since the QAR-F253 states that the splicing of rebar is not ASME.
2.
The " dress rehearsal" for the load transfer jacking of pier W12 will be held March 1, 1983 A meeting with heads of Engineering and MPQAD will be held on Monday February 28, 1983, to determine the number of men actually nee-essary to perform the work due to the area available.
3 A'. Scott questioned when the form tie-rod holes would be grouted for piers E/W12.
J. Fisher stated that this was under advisement at present.
4.
P. Barry & A. Scott requested a breakdown of the new organization chart in accordance to the old organization chart attached to Administrative Guideline, FSO-1.000 Revision 1.
In fact FSO-1.000 should be revised to incorporate the new chart.
