Summarized in this report are the results of in-place density tests performed at the subject site
during rough grading along.with pertinent observations. The project site is located near the 14
tee within the Madison Club development in the City of La Quinta, California.
Rough grading included over -excavation of the near surface soil along with the placement of
engineered fill soil throughout the building pad areas. Overexcavation extended to a depth of at
least 5 feet below pad grade. The underlying native soil was moisture conditioned and
compacted to a minimum of 90 percent relative compaction prior to fill placement. The
engineered fill soil was then placed in thin lifts at near optimum moisture content and compacted
to at least 90 percent relative compaction.
Field testing was performed from July 2, 2008 through July 7, 2008 Testing indicates a minimum
of 90 percent relative compaction was attained in the areas tested. The passing test results
indicate compliance with the project specifications at the tested locations and depths but are no
guarantee or warranty of the contractors work.
Field Tests: In-place moisture/density tests were performed using a nuclear density gauge in
accordance with test method ASTM D 6938-08. A total of 7 density tests were performed. The
approximate test locations are indicated on the attached plan and test results are summarized on
the attached data sheets.
