Dear Mr. -Vierra:
This report addresses the construction of an engineered
building pad•approkimately 501x100' on the above referenced
property.
Gravelly,, sand clay material for.the site was imported. The
.initial fill material had greater than 30% retained ona 3-"
sieve, so ASTM test Meth6d.1557 was not applicable. On this
portion of the fill a visual/proof rolling method was used.
All vegetation was removed from the pad area. Material was
moisture conditioned and compacted with a D-4 and a Case
602B vibratory compactor.. The fill was placed over a two
week period and was periodically observed during that time.
Additionally,. tests were taken by Nuclear Gauge Test Method
ASTM 2922,• and these results indicate the fill was
compacted in excess of 90% relative density. -The fill was
observed to be structurally stable and suitable".for a
single family.residence construction.
If you have any questions please call our office. -
Very truly yours, QQIOFESS/ONA
