1.3. SOIL TESTING AND CONSTRUCTION MONITORING
A.
Prior to and during placement of soil, the CQA Consultant may select areas
within the work limits for field compaction testing. CONTRACTOR shall
cooperate fully with the CQA Consultant during testing and shall allow the CQA
Consultant sufficient time to make necessary observations and tests.
OWNER will pay the CQA Consultant for testing. However, if test results
indicate inadequate compaction or earth materials not meeting the
Specifications, CONTRACTOR shall bear all costs associated with correcting
deficiencies in compacted materials to the satisfaction of the OWNER and the
CQA Consultant.
PART 2 - PRODUCTS
2.1 GENERAL
A.
The CQA Consultant shall collect soil samples for grain-size testing per ASTM
D422 and hydraulic conductivity tests (where applicable) per ASTM D2434 or
D5084 for each 3,000 cubic yards of each type of soil to be used in the Work.
In addition, the CQA Consultant will obtain a representative sample from each
source of the Drainage Sand for calcium carbonate testing. Soil materials not
meeting the requirements of this Section shall not be used in the Work. Test
methods for soil materials shall conform to the following, unless other
approved by the ENGINEER.
Particle-Size Analysis, with hydrometer - ASTM D422.
Atterberg Limits - ASTM D4318.
Standard Proctor - ASTM D698.
Hydraulic Conductivity - ASTM D2434 or D5084.
Internal Friction Angle - ASTM D3080.
We WNP
The final approval of a source for the soil will be at the sole discretion of
ENGINEER.
All earth materials unless otherwise specified, shall consist of suitable selected
and approved clean, well-graded granular soil.
All earth materials shall be substantially free from organic materials, wood,
trash, and other objectionable materials that may be compressible or that
cannot be properly compacted. Earth materials shall not contain stone blocks,
broken concrete, masonry rubble, or other similar materials. Earth materials
shall have the physical properties such that it can be readily spread and
compacted to the specified permeability and/or density. Snow, ice, and frozen
soil shall not be permitted.
