1.0 PURPOSE This procedura outlinea a means to determine the opti=um construction techniques for the placement and compaccion of the shell =aterial to be  !

placed directly on top of the final exposed pleistocene clay foundation.

2.0 SCOPE The scope of the procedure will cover the construction of a test fill including material and thickness, preliminary material testing, com-psetion field testing, data compilation, tabulation and analysis.

The final analysis of the data will result in a methoc specification W stipulating, material properties, lift enickness, type of compaction equipment, and compaction technique (number of passes, overlap, etc.).

h Once established, the inspection, documentation and Quality Control of h the construction of this shall blanket will be done in accordance with l

    • QCIP-I under the jurisdiction of the Senior Quality Control Supervisor.

s 6.0 PROCEDURE

[

a p 6.1 Material and Thickness.

[ Material shall be locally available clam shall and shall be subject to the approval of the Engineer. .It shall be free of vegetation,

. organic matter, rubbish, debria or other unsuitable material. One layer of material shall be installed, such that the final in-place thickness of the filter blanket shall not be less than twelve (12)~

~

inches. Care shall be' taken during placement and compaction not to disturb any asil instrumentation which may be in place. Inspech

tion of material condition, ' placement and compaction shall be recorded on Form QC-93.

I 6.2 Preliminary Material Testina A 250 pound representative sample of the clam shell material to be I

used in the test section shall be seit to a testing laboratory (either on site or off) and the following tests be run under the direction of the Site Soils Engineer. Results of the Laboratory ,

Tests shall be recorded on the appropriate QC Forms as given in QCIP-2.

NO. CP-2 03 T ISSUE: A . WATERFORD STEAM ELECTRIC STATION - UNIT NO 3 PAGE: 1 op 8 1.0 prRPOSE This procedure outlines a means to determine the optimum construction techniques for the placement and compaction of the shell caterial to be placed directly on top of the final exposed pleistocene clay foundation. ,

2.0 SCOPE .

~

The scope of the procedure will cover the construction of a test fill including material and thickness, preliminary material testing, com-paction field testing, data compilation, tabulation and analysis. ,

! The final analysis of the data will result in a method specification 1 M stipulating, material properties, lift thic kness , type of compaction

  • k equipment, and co=paction technique (number of passes, overlap, etc.).

Once established, the inspection, documentation and Quality Control of h the construction of this shell blanket will be done in accordance with 9

M QCIP-I under the jurisdiction of the Senior Quality Control Supervisor.
