On January 12 and January 13, 1989, a representative of our firm performed
density tests in the pad area on the above referenced project. Tests were
performed at random locations, in accordance :with ASTM D 2922-81 and
ASTM D 3017-78 Nuclear Density Test Procedure. Tests were performed as
per authorization of Tommy Rue.
The estimated locations of the tests are presented on the attached plan
with their results being summarized on the attached test report sheet. A
total of five (5) density tests were performed. Test results indicate that
after reworking areas of low density,
a minimum of ninety (90) percent relative compaction has been obtained
within the areas tested.
The maximum density -optimum moisture were determined in the laboratory
in accordance with ASTM D 1557-78, Method A or C.
Test results are as follows:
Light tan slightly
silty very fine to
fine sand

LIMITATIONS
This firm did not perform a soils investigation, did not conduct any tests to
determine the general condition, adequacy or stability of soils on the
property, nor did it observe the filling or compacting operations which were
already completed at the time our personnel were called to the site. The
only services performed were the specific moisture and density tests
summarized in this report. These test results provide only limited
information about the surface materials .observed at the locations and
depths tested and cannot be relied upon for information about subsurface
conditions or compaction, or to determine the appropriateness of any design
or construction'of improvements on the site. No inspection was made of the
contractor's work and no guaranty or warranty of that work in filling or
compacting of the soils on site is made or implied.
This report is issued with the understanding .that it is the
responsibility of the owner, or of his representative to insure
that this report is submitted to the appropriate governing
agencies.
If there are any questions, please do not hesitate to contact this office.
