Gentlemen:
Submitted here are the results of testing and observation of
construction materials at the referenced project. This report
addresses activities for the period of October 1 through 9, 1992.
on October 9, 1992, a sample of the imported fill material was
obtained and returned to the laboratory for development of an optimum
moisture-density relationship (Standard Proctor Curve). Test results
are attached as Plate 1.
During the period of October 1 through 9, 1992, a total of eight
field density tests were taken on the fill placed in the residential
building pads in Blocks B and C. Test results are shown on Plate 2.
Where tested, materials were found to be in compliance with project
specifications.
Additional reports will be submitted as the work progresses.
Sincerely,
RFR/aap

Gentlemen:
On October 5, 1992, five samples of the imported soil being used in
Phase IIIB were obtained and returned to the laboratory to determine
compliance with the project Plasticity Index (PI) requirement of 28
or less. Test results are as follows:

Based on the test results, the material sampled from Block B does not
comply with the project requirements. However, as this is the final
layer of fill, and is relatively thin, it is our recommendation that
this material be compacted.
If you have any questions, do not hesitate to call.
Sincerely,
