~ Assessment Team Observations - Construction s The Assessment Team observed the ongoing installation of the transfer frames for piers CT1/12. Work completed to date includes setting the '

, stabilizer plate and rockbolts into place, placement of the lower leveling and bearing plates, installation of the steel collar drift frame, placement of grout for the steel collar frame mudmat and setting the major transfer frame components into place. All concrete surfaces were roughened and moistened for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> in accordance with .

procedures. Grout placement for the steel collar frame mudmat was continuous avoiding segregation and bleeding. Erection and splicing required to set the steel collar drift frame into place was accomplished in accordance with the procedures. Despite the confined working area, the Contractor was able to move the transfer frame beams and posts into place without damaging the transfer frame members or the appurtenant components that have already been installed. It is the opinion of the Assessment Team that installation of the transfer frames performed to date has been accomplished in accordance with project procedures and good construction practice.

Assessment Team Observations - QA/QC The Assessment Team reviewed the design drawings assigned to the UAT work print station of the Auxiliary Building underpinning. The review consisted of checking the drawings for proper revision number, proper posting of attachments, legibility and proper identification stamps.

Four deficiencies were found with respect to posting of attachments and drawing revisions. As a result, NIR No. 24 was issued. The deficiency rate was less than 2 percent of the total attributes considered.

However, the Assessment Team recomends the Contractor should put forth additional effort to maintain the documents properly. During the review of this work print station, two additional drawings were posted that were not shown on the internal distribution list. The Contractor was informed and these drawings were added to the list.

Compressive strength testing for. piers CT1/12 concrete cylinders at the US Testing laboratory was overviewed by the Assessment Team. . Curing and capping of cylinders was accomplished in accordance with project procedures. During ic3d application, the US Testing technician performing the test did not use the maximum load indicator on the pressure gage as required by ASIM procedures. As a result, the Assessment Team issued NIR No. 25. All other aspects of the test were in accordance with procedures.

The Assessment Team reviewed 150 Inspection reports for proper certificatien of MPQAD inspectors. These reports covered inspections of various

= construction activities. Based on this_ review, the Assessment Team concludes that the Inspectors were properly certified.

Work Activity Packages No Work Activity Packages were overviewed or active during the past week.

March 27, 1984 for maintaining and distributing the Resident Engineers' controlled documents and attachments. The procedure requires that all FCRs/FCNs, DCNs and SCNs be attached to the back of the appropriate drawings. '

Previously, the procedures allowed the change documents to be either attached to the back of the drawing or listed on a block stamp on the front of the drawing and maintained in a separate location. The Assessment Team believes that designation of one method to post attachments to drawings will preclude the possibility of missing or improper posting of attachments. (CLOSES ITEM 77-13)

Item 80 Receipt Inspection of Piers CT1/10 Transfer Frames.

J. McMasterresponded to the Assessment Team question concerning receipt inspection of the transfer frames for piers CT3/10. MPQAD will inspect the transfer frames in the next two weeks. Since the i load transfer for piers CT3/10 is not scheduled until 7/84, imple-mentation of corrective action,'if required, will not impact completion of the piers. (CLOSES ITEM 80-6)

Item 80 Iower Bearing Plate at Pier Kc9.

]'.. D. lavelle responded to the Assessment Team question concerning compatibility of fabrication vs installation tolerances for the pier Kc9 bearing plate. An evaluation of the tolerances by FSO has shown that there is no conflict between fabrication and installation

, requirements. Based upon a Visual inspection, the underpinning sub-

! contractor rejected the bearing plate because of. warpage. A subsequent check of the rejected bearing plate with feeler gauges showed the plate to be within acceotabl.e tol.erances. (CIAW ITD4 79-5) 4 i

he Assessment Team has completed their review of doc'ument control '

procedures that have been revised to improve the handling and use of " retired" FCRs. In lieu of retiring one time deviation FCRs from the controlled documents after 30 days, all fbture one time deviation FCRs will either be directly incorporated into the design docu w nt or referenced on the document with a brief description.

Additionally, one time deviation FCRs written in the past will be incorporated into or referenced on the design-drawings. The Assessment Team believes direct incorporation or referencing of one time deviation FCRs on the design documents will improve the handling of this type of FCR. This item is now closed.
