3.12 DEFECTIVE AREAS
A.
If a defective area is discovered in the compacted soil, then the CQA Consultant
will notify CONTRACTOR who shall proceed to determine the extent and
nature of the defect. If the defect is indicated by an unsatisfactory test result,
then CONTRACTOR will determine the extent of the defective area by
additional tests, observations, a review of records, or other means that
CONTRACTOR deems appropriate. If the defect is related to adverse site
conditions, such as overly wet soils or surface desiccation, then CONTRACTOR
will define the limits and nature of the defect.
After the extent and nature of a defect has been determined, CONTRACTOR
shall correct the deficiency to the satisfaction of the CQA Consultant. The cost
of corrective actions shall be borne by CONTRACTOR.
Additional testing will be performed, CONTRACTOR to verify that the defect
has been corrected. This additional testing will be performed before any
additional work is allowed in the area of deficiency.
3.13 FIELD QUALITY ASSURANCE
A.
The CQA Consultant will monitor the placement and compaction of earth
materials.
The CQA Consultant will perform quality testing as outlined in the CQA Plan.
The CQA Consultant shall select locations to observe construction and perform
moisture content, gradation, and compaction tests. Where tests indicate that
the soil tested does not conform to the specified compaction requirements,
CONTRACTOR shall remove and recompact the material to the specified
density at no additional cost to OWNER.
Samples of the in-place Screened Till shall be obtained for laboratory hydraulic
conductivity testing. Sampling shall be performed using thin-walled tube
samplers in accordance with ASTM D1587. Laboratory testing for hydraulic
conductivity shall be accordance with ASTM D5084 and shall be performed at a
normal stress of 89 lb/in.2.
The presence of the OWNER, ENGINEER, or the CQA Consultant does not
