Description of Work.

1. The Contractor shall perform geotechnical and environmental soils testing. Specific tests include:

• ASTM D6913, “Particle‐Size Distribution (Gradation) of Soils Using Sieve Analysis.”

Assume no more than 101 samples for lab testing. Sieve sizes are described below.

• ASTM D4318, “Standard Test Methods for Liquid Limit, Plastic Limit, and Plasticity Index of Soils.” Assume no more than 101 samples for lab testing.

• ASTM D2216, “Standard Test Methods for Laboratory Determination of Water (Moisture) Content of Soil and Rock by Mass.” Assume no more than 20 samples for lab testing.

• ASTM D2974, “Standard Test Methods for Moisture, Ash, and Organic Matter of Peat and Other Organic Soils.” Assume no more than 5 samples for lab testing.

• ASTM D2434, “Measurement of Hydraulic Conductivity of Coarse-Grained Soils.” For estimating purposes, assume 10 samples for lab testing. Assume no more than 20 total samples for combined permeability (Constant or Falling Head) lab testing.

• ASTM D5084, “Measurement of Hydraulic Conductivity of Fine-Grained Soils.” For estimating purposes, assume 10 samples for lab testing. Assume no more than 20 total samples for combined permeability (Constant or Falling Head) lab testing.

The following sieve sizes shall be used for gradation testing (ASTM D6913): 1-in., 3/8-in., No. 4, No.7, No. 10, No. 14, No. 18, No. 25, No. 35, No. 40, No. 60, No. 80, No. 120, No. 170, and No.

200, and No. 230.

USACE personnel shall be responsible for delivery of all soil samples to the Contractor or his/her local representative. USACE will only pay for tests completed. The requested number of reconstituted, remolded Permeability tests (Constant or Falling Head) may vary based on results of Phase 1 and Phase 2 submittals. The Contractor shall retain all material of respective individual samples or requested sample blends until project closeout.

Performance Period.

Refer to Table 2. The period of performance for this contract is 70 calendar days from sample receipt by the lab.

Cost Proposal.

The Contractor shall submit a detailed cost proposal to USACE based on the Contract Line Items described in Table 3.

Submittals.

The Contractor shall perform the lab testing in phases. Refer to Table 2 for Phased Submittal timelines.

Submittal phases do not constitute a description of means and methods, and do not limit the scope of requested work that may be performed within the respective phase.

1. Phase 1 Submital shall include raw lab data covering approximately (63) samples denoted by “South” in a USACE-provided, future lab sample manifest. Test results due in this Phase 1

Submittal include raw lab data for ASTM D6913 Soils Gradation Testing and ASTM D4318 Atterberg Limits performed on each of approximately (63) samples. Phase 1 Submittal will also include raw data for no more than (20) ASTM D2216 Soils Moisture Content and no more than

(5) ASTM D2974 Soils Organic Content tests.

2. Phase 2 Submittal shall include raw lab data covering approximately (38) samples denoted by “North” in a USACE-provided, future lab sample manifest. Test results due in this Phase 2 Submittal include raw lab data for ASTM D6913 Soils Gradation Testing and ASTM D4318 Atterberg Limits performed on each of approximately (38) samples. Phase 2 Submittal will also include raw data for no more than (20) ASTM D2216 Soils Moisture Content and no more than

(5) ASTM D2974 Soils Organic Content tests.

3. Phase 3 Submittal shall include raw lab data covering approximately (20) blended samples denoted in a USACE-provided instruction, due to the Contractor from the government prior to the start of Permeability testing. Test results due in this Phase 3 Submittal include raw lab data for Permeability tests performed on respective samples marked for Permeability testing by either ASTM D2434 (Constant Head) or ASTM D5084 (Falling Head). These raw lab data, combined with Phases 1 and 2 submittals shall be incorporated into the cumulative Draft Lab Report.
