RE:. TRENCH CONSTRUCTION AA TRACT 28149 PGA WEST)
Dear Ed,
The City approves the trench detail prepared by NOS Consulting for the referenced tract with the
conditions listed below.. We suspect the three-inch lifts noted on the detail sheet are a bit
conservative and might be increased to six inches. In any case, we've included a condition which
will allow greater lift thicknesses provided they can be compacted.
1. The trench detail shall be revised to include a profile section indicating the nature of the
interface between CDF and native backfill and how it is to be constructed. The revised
trench detail shall be reviewed and approved by the Public Works Department prior to
issuance of a Public Works Department Encroachment Permit for the work.
r
2. Except as specified herein, all work and materials shall comply with the Standard
Specifications for Public Works Construction (1994).
3. Backfill materials shall brought to or maintained at an appropriate moisture content for
compaction. The appropriate moisture content range shall be established at the onset of the
project and ensured prior to use of the materials through progress testing on stockpiles.
4. The first trench backfilled shall be backfilled in the presence of the City Inspector.
Compaction shall be tested at random depths at approximate three-foot horizontal intervals
as backfill is placed to ensure the effectiveness of the compaction methods used and to
establish the depth of lift that can be compacted.
If lifts greater than one foot are attempted in this trial trench, compaction tests shall be
taken within the lifts to ensure that the full depth of the lift is compacted. Upon satisfactory
completion of this trench, the City Inspector shall establish the maximum lift thickness to be
compacted for the remainder of the project.
5.. In subsequent trenches, the frequency of compaction tests shall equal one per trench, on
average, randomly selected, with no more than three tests on any one trench.
CAW PURACTS\28149TRE.N CH
MAILING ADDRESS P.O. BOX 1504 - LA QUINTA, CALIFORNIA 92253 ��
The depth.of the randomly-selected compaction tests shall also be randomly selected except
that where multiple tests are required in a given trench, the tests shall be no closer than
three feet (horizontally) from each other.
6. If any compaction test fails, previously-placed backfill (in the same trench or previous
trenches) which is represented by the failing- test (as determined by the City Inspector), shall
