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 2 through 13, 1992.
During the above period a total of 43 field density tests were
performed on the fill placed within the residential building pads in
Blocks A, B, and C. In addition, four tests were performed on the
fill placed within Parker and Beau Drives. Test results are
summarized on Plates 1 through 3.
A large portion of these tests were taken on fill that was
previously placed by the excavation contractor in Blocks C and B.
While excavating test pits in these areas, a high PI (42) fill
material was encountered. This material was located in Block C,
Lots 4 through 9 and Block B, Lots 6 ~through 9. The thickness of
this material ranged from two to three feet. The contractor is
presently in the process of removing this material from the pad
areas and replacing it with an approved material. Compaction tests
will be performed on this fill as the material is placed.
