Gentlemen:
Submitted here are the results of testing and observation of
construction materials at the referenced project. This report
addresses the activities for the period of July 14 through 23,
1992.
On July 14, 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.
On July 15, 1992, a sample of imported fill material was obtained
from the front half of the proposed residential building pads in
Block A, Lots 28 through 38, and returned to the laboratory to
determine the Plasticity Index (PI). The material was found to have
a PI of 33 and did not comply with the project specifications
(maximum PI of 28). The contractor was notified of the results and
a low PI clayey sand was mixed with the unapproved material. After
mixing, a sample was obtained to verify compliance with the project
specifications. The material was approved and an optimum moisture-
density relationship (Standard Proctor Curve) was performed. Test
results are shown on Plate 2.
During the period of July 14 through 23, 1992, a total of 55 field
density tests were taken on the imported fill material placed in the
residential building pads in Blocks A, B and C, and within Alley B-1
and Brentwood Drive. Test results are shown on Plates 3 and 4.
Where tested, the materials were found to be in compliance with
project specifications.
