EXHIBIT A, GENERAL SOIL SAMPLE NOTES

EXHIBIT A, GENERAL SOIL SAMPLE NOTES

Unless noted, all terms utilized herein refer to the Standard Definitions presented in ASTM D 653. Standard Penetration Test (ASTM D 1586) - A 2.0" outside-diameter, 1-3/8" inside-diameter split barrel sampler is driven into undisturbed soil by means of a 140-pound weight falling freely through a vertical distance of 30 inches. The sampler is normally driven three successive 6-inch increments. The total number of blows required for the final 12 inches of penetration is the Standard Penetration Resistance (N). COHESIVE SOILS COHESIONLESS SOILS

Approximate Unconfined Compressive Density Approximate

Consistency Range of (N) Strength (psf) Classification Range of (N) Very Soft 0-2 Below 500 Very Loose 0-4 Soft 3-4 500-1,000 Loose 5-10 Medium 5-8 1,000-2,000 Medium Compact 11-30 Stiff 9-15 2,000-4,000 Compact 31-50 Very Stiff 16-30 4,000-8,000 Very Compact Over 50 Hard 31-50 8,000-16,000 Very Hard Over 50 Over 16,000

*If Clay content is sufficient so that clay dominates soil properties, clay becomes the principal noun with the other major soil constituent as modifier: i.e., silty clay. Other minor soil constituents may be included in accordance with the classification breakdown for cohesionless soils: i.e., silty clay, trace of Sand, little gravel. CLASSIFICATION PARTICLE SIZES

The major soil constituent is the principal noun, i.e. sand, silt, gravel. The second major soil constituent and other minor constituents are reported as follows:

Boulders Cobbles

- Greater than 12 inches (305 mm) - 3 inches (76.2 mm) to 12 inches (305 mm)

Second Major Constituent Minor constituents Gravel: Coarse - ¾ inches (19.05 mm) to 3 inches (76.2 mm) (percent by weight (percent by weight) Fine - No. 4 - 3/16 inches (4.75 mm) to ¾ inches

(19.05 mm) Trace - 1% to 11% Trace - 1% to 11% Sand: Coarse - No. 10 (2.00 mm) to No. 4 (4.75 mm) Medium - No. 40 (0.425 mm) to No. 10 (2.00 mm) Adjective - 12% to 35% Little - 12% to 22% Fine - No. 200 (0.074 mm) to No. 40 (0.425 mm) (clayey, silty, etc.) Silt - 0.005 mm to 0.074 mm Some - 23% to 33% Clay - Less than 0.005 mm And - Over 35%

If sand particle size is greater than 11% by weight of the total sample weight, the adjective (i.e. fine, medium or coarse) is added to the soil description for the sand portion of the sample, provided sand is the major or second major constituent.
