Subject: Final Soils Report – Certification of Compaction for Site Improvements
Proposed Palomar Road Site, Exterior & Interior Improvements
2051 Palomar Airport Road
Carlsbad, California 92011
Mr. Gowen:
As requested, Construction Testing & Engineering, Inc. (CTE) has performed observation and testing of
compacted fill materials during recent site improvements. This letter is provided as certification that the
recent fill or backfill placement has been conducted in substantial conformance with the applicable
plans and specifications for the project.
Field-testing of the compacted trench fill material was conducted as scheduled by the contractor
between May 8 20, 2020 and March 24, 2021. Testing was performed in general accordance with
ASTM D-6938 (nuclear method). Results of the field-testing indicate that fill materials in the subject
areas were compacted to a minimum of 90 and 95 percent (depending on location and requirements) of
the laboratory maximum dry density as determined by test method ASTM D-1557. Tabulated results of
the field compaction testing performed are provided in the attached Table I, “Compaction Test
Summary”. The laboratory maximum density results are provided in Table II, “Laboratory Test
Results.” Figure 1 provides approximate compaction test locations.
This letter is subject to the same limitations as the other project geotechnical documents. The
opportunity to be of service is appreciated. If you have any questions, please do not hesitate to contact
this office.
