PROCEEDING WITH THE PRODUCTION DENSIFICATION. UPON COMPLETION OF

TEST PADS, PERFORM CPT VERIFICATION TESTS AT LOCATIONS MIDWAY

BETWEEN COMPACTION POINTS AND APPROVED BY THE CONTRACTING OFFICER.

4. ALL CPTS SHALL BE PERFORMED IN ACCORDANCE WITH ASTM D5778 AND SHALL

BE PERFORMED NEAR THE CENTRAL PORTION OF THE DENSIFIED AREAS WITH AT

LEAST 2 CPT SOUNDINGS PER TEST PAD.

5. CPT SOUNDINGS SHALL BE LOCATED EQUIDISTANT TO THE CENTERS OF THE

VIBRO-COMPACTION ELEMENTS, WITHIN THE REGION RECEIVING THE LEAST

DENSIFICATION IMPROVEMENT.

B. SUBMIT A TEST PAD DENSIFICATION PROGRAM REPORT AND SURVEY, TO INCLUDE THE

TEST RESULTS OF ALL SPECIFIED TESTS AND THEIR IDENTIFYING LOCATION AND

RELATIONSHIPS TO ADJACENT COMPACTION POINTS:

1. IDENTIFY EACH COMPACTION POINT AND ITS DATE AND TIME OF INSTALLATION.

POINTS.

3. ALLOW 5 WORKING DAYS FOR REVIEW BY CONTRACTING OFFICER AFTER THE

SUBMITTAL OF THE TEST PAD DENSIFICATION PROGRAM REPORTS, SURVEYS, AND

PROPOSED DENSIFICATION METHOD STATEMENT FOR PRODUCTION SOIL

DENSIFICATION. NO PRODUCTION SOIL DENSIFICATION SHALL BEGIN UNTIL THE

REPORT HAS BEEN REVIEWED.

C. A POST TEST-PAD MEETING WILL BE REQUIRED TO DISCUSS RESULTS OF THE TEST-PAD

INSTALLATION AND VERIFICATION TESTING AND ANY POSSIBLE CHANGES TO THE

ORIGINAL PROCEDURES.

D. ANY CHANGE IN THE PREDETERMINED DENSIFICATION INSTALLATION PROGRAM SHALL

BE IMMEDIATELY REPORTED AND SUBMITTED TO THE CONTRACTING OFFICER.

E. PROBE HOLES:

1. CONTRACTOR MAY, AT NO ADDITIONAL COST TO THE GOVERNMENT, COMPLETE

PROBE HOLES AT SELECT LOCATIONS WITHIN THE AREA OF EACH FOUNDATION

ELEMENT TO BE DENSIFIED TO DETERMINE REFUSAL DEPTH PRIOR TO

PRODUCTION OF VIBRO-COMPACTION ELEMENTS.

a. BACKFILL PROBE HOLES WITH REPLACEMENT AGGREGATE AS REQUIRED TO

FILL ANY VOID MADE BY THE PROBES.

POSSIBLE AND SHALL NOT DEVIATE BY MORE THAN 1 FOOT IN 20 FEET.

B. THE LOCATION OF VIBRO-COMPACTION-SUPPORTED FOUNDATIONS FOR THIS PROJECT,

INCLUDING LAYOUT OF INDIVIDUAL COMPACTION POINTS, SHALL BE MARKED IN THE

FIELD USING SURVEY STAKES OR SIMILAR MEANS AT LOCATIONS SHOWN ON THE

LOCATIONS SHOWN ON THE DESIGN DRAWINGS.

3.04 VERIFICATION OF DENSIFICATION:

A. VERIFY DEGREE OF DENSIFICATION BY MAKING CONE PENETRATION TESTS (CPT) IN

ACCORDANCE WITH ASTM D5778, AS FOLLOWS:

1. NO LESS THAN 1 CPT SOUNDING PER 750 SQUARE FEET OF IMPROVED AREA. THIS

NUMBER DOES NOT INCLUDE CPT SOUNDINGS PERFORMED FOR TEST PADS.

OFFICER.

4. EXTEND EACH CPT SOUNDING TO A MINIMUM OF 5 FEET BELOW THE BASE OF THE

VIBRO-COMPACTION DEPTH.

5. RESULTS OF CPT SOUNDING SHALL DEMONSTRATE DENSIFICATION OF THE SOILS

TO A MINIMUM OF 85% RELATIVE DENSITY WHEN DETERMINED FROM ACCEPTED

CORRELATIONS WITH CPT DATA.

6. A MINIMUM OF 90% OF DATA POINTS SHALL DEMONSTRATE THAT THE MINIMUM

DENSITY IS ACHIEVED.

B. THE CONTRACTOR MAY ELECT TO DELAY DENSIFICATION VERIFICATION TESTING TO

ALLOW FOR TIME-RELATED IMPROVEMENT:

1. THIS DELAY IS AT THE CONTRACTOR'S RISK AND EXPENSE, AND DOES NOT RELIVE

THE CONTRACTOR FROM ANY PROGRESS TESTING REQUIREMENTS REQUIRED

UNDER "PROGRESS VERIFICATION."

2. EXPERIENCE WITH VIBRO-COMPACTION TECHNIQUES IN SOME SATURATED SOILS

VALUES ARE MET OR EXCEEDED BY TESTING WITHIN 200 HOURS AFTER SOIL

IMPROVEMENT HAS BEEN COMPLETED FOR THE AREA BEING TESTED.

3. DENSIFICATION VERIFICATION TESTS OUTLINED HEREIN ARE INTENDED TO BE

ACCOMPLISHED ITEM BY ITEM, UNIFORMLY OVER THE EXTENT OF SITE, IN A

SEQUENTIAL MANNER.

a. SHOULD THE CONTRACTOR PROPOSE TO COMBINE CERTAIN OF THESE

SEQUENCES TO SAVE TIME AND THE RESULTS PROVE TO BE UNACCEPTABLE,

THE DEFICIENCIES SHALL BE CORRECTED AT NO ADDITIONAL EXPENSE TO

THE GOVERNMENT.

b. PRODUCTION DENSIFICATION WORK COMMENCING PRIOR TO APPROVAL OF

THE TEST RESULTS SHALL BE CONSIDERED DONE AT THE CONTRACTOR'S

RISK, REMEDIAL MEASURES DEEMED NECESSARY BY THE ENGINEER TO

CORRECT DEFICIENCIES IN SUCH AREAS SHALL BE ACCOMPLISHED AT NO

ADDITIONAL COST TO THE GOVERNMENT.

c. SHOULD THE MINIMUM ACCEPTANCE VALUES NOT BE MET, THE CONTRACTOR

SHALL INSTALL ADDITIONAL COMPACTION POINTS TO ATTAIN THE SOIL

IMPROVEMENT CRITERIA AT NO ADDITIONAL COST TO THE GOVERNMENT.

C. VIBRO-COMPACTION VERIFICATION TESTING SHALL BE PERFORMED BY AN INDEPENDENT

TESTING LABORATORY, RETAINED BY THE CONTRACTOR, AND APPROVED BY THE

1. AS THE SOIL DENSIFICATION WORK PROGRESSES, CONDUCT TESTS AT

INTERVALS DESCRIBED IN "VERIFICATION OF DENSIFICATION" TO VERIFY

THAT NO LESS THAN THE SPECIFIED MINIMUM DEGREE OF DENSIFICATION IS

BEING ACHIEVED:

a. IF TESTING INDICATES THAT THE MINIMUM DEGREE OF DENSIFICATION

IS NOT BEING MET, DISCONTINUE ADVANCEMENT INTO NEW AREAS AND

REPEAT THE DENSIFICATION PROCESS IN THE FAILED AREA(S), AT NO

COST TO THE GOVERNMENT, MAKING MODIFICATIONS IN THE PROCESS

AS NECESSARY TO PROVIDE NO LESS THAN THE SPECIFIED MINIMUM

DEGREE OF DENSIFICATION.

b. REPEAT THIS CYCLE OF DENSIFICATION AND TESTING UNTIL ALL

SPECIFIED REQUIREMENTS FOR SOIL DENSIFICATION ARE MET IN ALL

REQUIRED AREAS.

c. THE CONTRACTING OFFICER MAY REQUIRE ADDITIONAL TESTS AS

DEEMED NECESSARY AT NO ADDITIONAL COST TO THE GOVERNMENT.

G. REJECTED DENSIFICATION CONDITIONS:

1. SHOULD THESE MINIMUM VALUES NOT BE MET, THE CONTRACTOR SHALL

CONSTRUCT ADDITIONAL DENSIFICATION POINTS ADJACENT TO THE FAILING

COMPACTION POINTS TO ATTAIN THE SOIL IMPROVEMENT CRITERIA.

a. ALL WORK TO ACHIEVE THE SPECIFIED CRITERIA, INCLUDING

INSTALLING ADDITIONAL VIBRO-COMPACTION AND PERFORMING

ADDITIONAL VERIFICATION TESTING SHALL BE PROVIDED BY THE

CONTRACTOR AT NO ADDITIONAL COST TO THE GOVERNMENT.
