SPECIAL PUBLICATION NO. 57


 i. Use of CPT soundings often is used because the data may assist
 with the indication of traveling soils.

 ii. Conductivity tips are useful to determine the presence and
 continuity of a clay confining layer.

 iii. All sounding locations should be located relative to landmarks so
 they can be identified at a later date.

f. Auger Borings (hand, tripod, trailer, truck mounted, etc)

 i. Advanced near the foundation for identification of soil depth and
 classification.

 ii. A calibrated manual cone penetrometer is recommended for testing
 strengths of soils in the auger holes.

 iii. All hand auger holes should be located relative to landmarks so
 they can be identified at a later date.

 iv. If more than one foot of relief is present, the relative elevations of
 the borings should be determined by leveling.

 v. It is recommended that a hand auger boring be advanced at each of
 the four primary corners of the structure and in any areas of
 concern, such as depressions elsewhere on the property.

 vi. All holes created by auger boring will be properly filled.

g. Manual Cone Penetrometer (CPT) Soundings

 i. Used for determination of the relative strengths of soils near the
 foundation of the structure and in areas of concern.

 ii. Hand penetrometers should be calibrated.

 iii. Report results of the soundings, including units of soil strength
 measurement.

 iv. Report whether the soil strengths determined by CPT were taken in
 hand auger borings or other excavations where side friction is
 minimal or in undisturbed soil.

h. Foundation Test Pits

 i. The consultant should attempt to obtain design documents from the
 owner or local building department if there is any question as to
 design elements in the foundation of the structure.
