WAS OBSERVED BUT NO GRADA T ION TEST WAS
PERFORMED,
3, THE GEOTECHNICAL DATA IS ONLY DESCRIPTIVE OF
THE L OCA T IONS ACTUALLY SAMPLED, EX TENS ION OF
THIS DATA OUTSIDE OF THE ORIGINAL BORINGS MAY
BE DONE TO CHARACTERIZE THE SOIL CONDI T IONS,
HOWEVER, COMPANY DOES NOT GUARANTEE THESE
CHARACTERIZATIONS TO BE ACCURATE, CON TRAC TOR
