Gentlemen:
Submitted.here ar~ the results of testing and observation of
construction materials at the referenced project. This report
addresses the activities for the period of August 5 through 13, 1993.
During the referenced period, a total of 34 field density tests were
taken on the natural subgrade and fill placed on the residential
building pads. Tests results are shown on Plates 1 and 2. Where
tested, materials ~ere found to be in compliance with project
specifications, e~cept as noted. Where materials were not in
compliance, the soils were reworked and retested. Test failures and
retests are noted !in lower and upper case letters, respectively.
Additional testing will be submitted as the work progresses.
questions arise, do not hesitate to call.
If any
Sincerely,
REED ENGINi~
