Dear Mr. Guzman:
In accordance with your request, we provided compaction testing and observation services during
construction of improvements at the subject project. We provided our services between August 2024
and August 2025.
The scope of our services consisted of performing in-place density tests on a “call out” basis during
minor grading and trench backfill of underground utilities (see Table I for specific utilities) and wall
backfill. We also performed in-place density tests on curb/gutter subgrade, drive isle/parking lot
subgrade, aggregate base and asphalt concrete pavement.
Carlsbad Oaks North Business Park – Lot 3
Final Report of Testing and Observation Services Performed During Improvement Construction
Project No. 06442-32-34B - 2 - August 29, 2025
We provided full-time testing and observation services during construction of Mechanically Stabilized
Earth (MSE) retaining wall No. 1. Specific to MSE wall No. 1, our services consisted of observing the
foundation excavation prior to placement of base rock and block layers, observing geogrid placement
and observing installation of the wall drainage system. We understand that the wall drain will be
connected to the project storm drain system by TFW Construction Incorporated, the project general
contractor.
Reinforcement of the wall consisted of Miragrid 3XT. We checked that the grid lengths were consistent
with the project plans (Reference 4) during wall construction. Slack was removed from the grids by
pulling the grid tight and either nailing the back of the grid down or placing soil on the back of the grid.
Our observations indicated that the grids were placed in substantial conformance with the referenced
plans.
The wall drain system was constructed in general conformance with the project plans. The drain
system placed behind the wall units consisted of a 4-inch-diameter, PVC perforated drainpipe
encapsulated in ¾-inch gravel and wrapped in Mirafi 140N filter fabric.
Minor grading consisted of constructing the portion of fill slope above the MSE wall that was removed
as part of the wall back cut excavation. Soil fills were placed in lifts no thicker than would allow for
adequate bonding and compaction. The soil was moisture conditioned, as necessary, and mixed during
placement.
We performed in-place density tests in general conformance with ASTM D 6938 for soil and aggregate
base, and ASTM D2950 for asphalt concrete. Table I presents the in-place dry density and moisture
content tests results.
Where fill soil contained rock larger than ¾-inch, a correction was made to the laboratory maximum
dry density and optimum moisture content using methods suggested by AASHTO T224. The values of
maximum dry density and optimum moisture content presented on Table I reflect these corrections
Results of in-place density tests indicate soil placed during minor grading, trench backfill, wall backfill,
and curb/gutter subgrade possess a dry density of at least 90 percent of the laboratory maximum dry
density near or slightly above optimum moisture content at the locations tested. Similarly, a relative
compaction of at least 95 percent was achieved on the drive isle/parking lot subgrade soil, aggregate
base and asphalt concrete.
Carlsbad Oaks North Business Park – Lot 3
Final Report of Testing and Observation Services Performed During Improvement Construction
Project No. 06442-32-34B - 3 - August 29, 2025
We performed laboratory compaction tests on representative soil samples in accordance with ASTM
D 1557 (maximum dry density and optimum moisture content), D 4318 (Atterberg Limits), D 6913
(sieve analyses for soil) and AASHTO T-236 (shear strength characteristics). We also performed
laboratory tests on asphalt concrete samples in accordance with ASTM D 2726 (Hveem density),
D 2041 (theoretical maximum density), D 1560 (asphalt concrete stability), D 6307 (asphalt content),
and C 136 (sieve analysis for asphalt). Tables II through VI present the laboratory test results. Figures
1 through 4 present the direct shear and sieve analyses laboratory test results.
If there are questions regarding this report, or if we may be of further service, please contact the
undersigned at your convenience.
Very truly yours,

rounded to the nearest whole foot.
CURVE NO.
Corresponds to the curve numbers presented in the summary of the laboratory maximum dry density and optimum
moisture content test results. The field representative selected the curve no. based on the laboratory test results and
field observations.
>¾" ROCK - ROCK CORRECTION
The laboratory maximum dry density and optimum moisture content can be adjusted for in-place soil that possesses
rock larger than ¾ inch. The curve no. is adjusted for the percentage of ¾ inch rock in accordance with ASTM D 4718 or
Woodward Clyde guidelines.
