2.1.4 Unstable Material

Unstable material is material too wet to properly support the proposed structure or utility.

SECTION 31 00 00.00 13 Page 5 AMEND. 0003

2.1.5 Proctor

Degree of compaction required is expressed as a percentage of the maximum density obtained by ASTM D698. The maximum density is hereafter abbreviated as the "Standard Proctor" or "Proctor" value. The optimum moisture content is the water content at which the soil is compacted to the maximum density as determined in ASTM D698.

2.1.6 Dam Embankment

Dam Embankment is defined as the earth fill portions of the dam structure and is constructed out of Impervious Fill.

2.1.7 Foundation

Foundation means any area that has been excavated or stripped and will receive impervious fill or geotextile, including the bottom and side slopes of the inspection trench.

2.1.8 Foundation Evaluation

This is the evaluation to determine the foundation adequacy and document the foundations. This evaluation is performed by the Government with assistance of the Contractor's equipment and staff. Foundation evaluation includes inspection, testing, geologic mapping, sampling, exploratory test pits, interpretation, excavation and disposal of undesirable materials, proof rolling, and decision making.

2.1.9 Foundation Preparation Checklist

A checklist filled out by the Contractor to provide proper notification to the Contracting Officer and ensure the Contractor performs adequate surface preparation for the Foundation Evaluation. This checklist is attached to the end of this section.

2.1.10 Inspection Trench

The inspection trench, as detailed in the plans, is an excavation intended to expose undesirable subsurface features.

2.1.11 Proof Rolling

Proof rolling means driving an appropriate weighted vehicle at walking speed to expose signs of unstable subgrade. An appropriate vehicle is a tandem axle truck with a gross weight of 25 tons or an approved equivalent, driven over the foundation at speeds between 2-1/2 to 3-1/2 miles per hour.

The Contractor and the Contracting Officer shall agree on the appropriate vehicle based on the field conditions and the material being evaluated.

2.2 MATERIALS

2.2.1 Sherack Material

Sherack Material is the uppermost clay deposit in the project area under the topsoil. The upper 5 feet are generally dark gray-brown and difficult to distinguish from topsoil by color. The lower portion of the Sherack Material is generally brown to yellow-brown with iron stains.

Sherack Material typically has a liquid limit between 60 and 92, a plasticity index between 38 and 67, and is classified by ASTM D2487 as CL or CH. These liquid limit and plasticity index values are not contractual limitations but are meant to assist in identifying the material.

2.2.2 Brenna Material

Brenna Material is below the Sherack Material and is generally a soft to very soft clay, dark gray in color, and highly plastic. Brenna Material typically has a liquid limit between 75 and 116 and a plasticity index between 50 and 86. These liquid limit and plasticity index values are not contractual limitations but are meant to assist in identifying the material.

2.2.3 Impervious Fill

Impervious fill shall meet the following requirements:

a. The material shall be satisfactory material.

b. The material shall be cohesive material.

c. The material shall be Sherack material.

d. The material shall not include topsoil.

e. The material shall not include Brenna material.

During subsurface investigations, the highest contact elevation located between the Brenna and Sherack formations occured at EL 897.7. The contact elevation varies throughout the project and could occur at a higher elevation within the project footprint.

2.2.4 Topsoil

Topsoil for this project shall be obtained from the on-site stripping and excavations. It shall be free of subsoil, stumps, rocks larger than one inch in any one dimension, brush, weeds, toxic substances, and other material detrimental to plant growth.

2.3 DAILY EARTHWORK REPORT FORMS

Use the daily earthwork report forms in the attachments at the end of this section to document earthwork.

SECTION 31 00 00.00 13 Page 7 AMEND. 0003

12 APR 2022

2.4 EARTHWORK FINAL REPORT

After the earthwork is complete, submit the Earthwork Final Report for review in pdf format.

Throughout the performance of the Contract, the Contractor shall continually compile all the information for the Earthwork Final Report and have the information available for review by Contracting Officer at all times. Include the following information in the Earthwork Final Report:

a. Testing results indicated in paragraph TESTING, ordered by test number;

b. Full size as-built plans with test numbers inserted to show location and elevation in plan and profile view;

c. Finalized daily earthwork reports with all attachments, ordered by date;

d. Narrative including unusual conditions or situations encountered;

remedies applied to address these conditions or situations; and description of job sequencing and work schedule with workdays per week (by season) and any extended "no work" period.
