On January 14, 1988 a representative of our firm performed density tests
on two (2) house pads at the above referenced project. Test 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 Mr. Straff in.
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 -four (4) density tests were performed. Test results indicate that a
minimum of ninety (90) percent relative compaction has been )btained
Within the areas tested.. .
The maximum density -optimum moisture were determined in the layoratory
in accordance with ASTM D 1557-78, Method A or C.
Test results are as follows:

The only services performed were the specific moisture and dens1ty tests
summarizedin 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
