Compaction Report
Gentlemen:.
On January 21, 1985 a representative of our firm performed-den-
sity
erformed density tests on the"fill"placed in the building area on the above-
re-ferenced'-project. Tests were performed at random -locations in ac-
cordance with'ASTM 2922-78 and ASTM 3017-78 Nuclear Density Test
Procedure. Tests.performed as -per authorization of Bob Mc Callum.
The estimated locations of the tests are presented ori the attach-
ed plan with their.results being summarized on the attached.test re-
port"sheet. A total of six (6) density tests were performed.
Test results indicate that a minimum of ninty percent :90%) of rela-
tive compaction has been obtained within the areas tested. The
maximum density -optimum -moisture was determined in the laboratory in
accordance with ASTM D 1557-78, Method A, five (5) layer curve.,

LIMITATIONS
The backfilling and compacting operations were completed.'at the
time.our personnel were called to the site. The test results summa-
rized in.this'report represent the moisture and density only at the
location and depth tested on the specified date. The summarized. -field
and.'labor"atory tests were performed in accordance with engineering
principles generally.accepted at this time and location.
No opinion
is expressed as.to the uniformity of the material, compaction nor the
adequacy of the material.to perform its intended function. No quar-
antee or warranty of,the contractors work''is made or implied.

Attention: Mr. Rick Johnson
SUBJECT: Report of In -Place Density Tests, Proposed Bob Monroe Residences,
Lots 20 thru'22, Ramirez Avenue, LaQuinta, California.
Gentlemen:
In accordance with your request, 'this report has:been prepared to present..the
results of the in -place -density tests performed on -the fill material at the
subject sites by Southern Californ to Soil & Test in'g:; Inc. These tests were per-
formed-on
erformed on January 15, 1985.
AVAILABLE PLANS
Grading plans' were not made available to us to indicate.the elevations of our
• field density tests and to define the general extent of the site grading. There-
fore,.we have provided a hand sketch indicating the graded areas -and the-lo.cations
of our tests.
SITE PREPARATION
Upon arrival at the job sites, a representative of Southern Calil-ornia Soil and
Testing, Inc. noted that up to three (3.) feet of fill material had"been placed
' on the lots. -It was observed that both.the natural soil and-theupper foot of

Report No. 1
fill material had not been properly moisture conditioned.
FIELD TESTING
Field density tests were performed by a representative of Southern California
Soil & Testing, -Inc. following compaction operations., The density tests were
taken according to.A.S.T.-M. Test 1556=74 and the location and results of those
tests are shown on the attached plates. The locations and elevations of the i
in -site tests were.determinedin accordance.with their importance and the ac-
curacy and proximity of the survey control'provided by other than Southern
California Soil & Testing, Inc. representatives. Unless otherwise noted, their
locations and.elevations were determined by pacing and hand level methods and
should be considered accurate only to the degree implied by the.method'used.
LABORATORY TESTS
Maximum dry dens.ity determinations were.performed on representative samples -of
the soils used in the compacted fills according to A.S.T:M. Test.1557-78,Method
A. This method specifies that a -four (4) inch diameter -cylindrical -mold of 1/30
cubic foot volume.be.used and that the soil tested by.,place din five (5) equal
layers .with each,.layer compacted by twenty-five (25) blows..of a l0 pound hammer
with a 18 -inch drop. The results of these tests, as presented`.on Plate,Number
2, were used in conjunction.with the field density tests to deternine the per-
cent of relative compaction of the compacted fill.
CONCLUSIONS
The results of'our.field density tests -indica.te that the natural soil on each
lot tested.did not meet the standard requirements of 90% -relative: compaction.

Report. No. 1
Our client 'informed'us that..the grading contractor requested another testing
laboratory be assigned to the project. As a result, no retests were taken by
our firm. This report.covers only the work performed on -January 15, 1985.
Our opinions presented herein are based on our observations and -the relative
compaction tests results. Due -to possible variations in the.uniformity.of
compacted fills, we only warrant that our work. was performed in accordance with
the currently accepted standards of:practice. No. other warranty, -express or,
'implied is given or intended.
If you should have any questions after reviewing this report,. please•do not
hesitate to'contact this office.
This opportunity to be°of-professional service is sincerely apprEciated.
