Mr. Will Dukes
Asana Partners 11752 San Vicente Boulevard Los Angeles, California 90049
Subject: Second Update to Final As-Graded Report The Beacon Phase 3 7760 and 7770 El Camino Real, Carlsbad, California
GR2021-0024
Dear Mr. Dukes:
In accordance with your request, Ninyo & Moore has provided compaction testing services during
the construction phase of The Beacon Phase 3 project at 7760 and 7770 El Camino Real in
Carlsbad, California. Our services included the compaction testing of the earthwork operations
performed for this project. This report summarizes our services and presents the results of our field
and laboratory testing.
PROJECT DESCRIPTION
The project included tenant improvements to the existing buildings at 7760 and 7770 El Camino Real
along with new exterior site improvements to the surrounding areas of the buildings. The focus of
this report are the exterior improvements that included a trach enclosure, new landscaped islands in
the parking lot, reconfiguration of the Americans with Disabilities Act (ADA) parking stalls,
underground utilities, concrete curbs, sidewalks, landscaping, and a few gravity site walls.
FIELD COMPACTION TESTING
Our field technician was onsite on an on-call basis between February 6, 2023 and April 14, 2023 and
onsite on July 9, 2023 and August 31, 2023 as well to test and retest water line trench backfill, utility
trench backfill, subgrade soils, and aggregate base materials. Field density tests were performed by
our technician in general accordance with the current version of ASTM International (ASTM) D 6938
(Nuclear Gauge Method). The specified relative compaction for general backfill materials associated
with water line trenches and the subgrade soils for sidewalks, curbs, and gravity walls was 90 percent,
as evaluated by ASTM D 1557. The specified relative compaction for the upper 1 foot of backfill

materials associated with water line and utility trenches beneath pavements along with subgrade soils
for the parking lot pavements and the aggregate base materials was 95 percent, as evaluated by
ASTM D 1557. The results of our field density tests are presented in Attachment A and the approximate
test locations are shown on Figure 1.
During the course of the project, failing subgrade tests were recorded for two of the gravity site walls.
For the gravity site wall near the roundabout to the northeast of 7760 El Camino Real, the initial
compaction test (SG-15) on the subgrade soil indicated a relative compaction of less than
90 percent, primarily due to the over optimum moisture content of the soil. Retests SG-16 and SG-17
were performed on subsequent days, which also indicated relative compactions of less than
90 percent. After performing the second retest, the contractor elected to proceed with the concrete
placement for this gravity site wall. Subsequent to construction further retesting of this area was
performed on June 9, 2023. The retest (RT-1) indicated a relative compaction meeting the specified
90 percent.
Additionally, a compaction test (SG-32) was performed on the subgrade soil for a gravity site wall
south of 7770 El Camino Real that initially indicated a relative compaction of less than 90 percent.
Subsequent to construction further retesting of this area was performed on August 31, 2023. The
retest (RT-2) indicated a relative compaction meeting the specified 90 percent.
LABORATORY TESTING
Laboratory testing was performed on the soil and aggregate base materials used during the
earthwork operations to evaluate their modified Proctor and optimum moisture content relationships.
The modified Proctor densities and optimum moisture contents were evaluated in general
accordance with the ASTM D 1557, and the results are summarized in Table 1. The modified Proctor
densities and optimum moisture contents of the aggregate base material represented by Soil Type
Numbers 4 and 6, were provided by the material supplier and are also presented in Table 1.
SUMMARY
The field density tests performed for the earthwork operations associated with the subject project for
permit GR2021-0024 indicated the specified relative compactions, after the retests were performed.
Based on our observations and the results of our field and laboratory tests, it is the opinion of
Ninyo & Moore that the earthwork were performed in accordance with the referenced reports
(Ninyo & Moore, 2017 & 2021) and the project drawings (Drawing No. 532-1A), after retesting was
performed.

LIMITATIONS
The compaction testing services outlined in this report have been conducted in accordance with
current practice and the standard of care exercised by geotechnical consultants performing similar
tasks in this area. No warranty, expressed or implied, is made regarding the observations and
conclusions expressed in this report. The reported test results represent the relative compaction and
moisture content at the locations tested. It is important to note that the precision of field density tests
and the modified Proctor tests is not exact and variations should be expected. The reported locations
and elevations of the density tests were estimated from construction staking and the referenced
plans (City of Carlsbad, 2022). Further accuracy is not implied.
