OBJECTIVES AND SCOPE OF NOVA’S SERVICES
Objectives
The objectives of the work reported herein were twofold, namely: (i) to observe geologic conditions
encountered during grading, and (ii) to document that earthwork/grading was completed in
conformance with the requirements of the design documentation listed above.
Scope
In order to accomplish the above objectives, NOVA undertook the scope of services abstracted below
during the period of relevant construction, July 20, 2020 to September 18, 2021.
1. Observation and Testing. Performed observation and testing as requested by the contractor
during grading (removals and compaction) and post-grading (pavements and utilities)
operations. Quality Assurance (QA) in-place density testing of soils placed as compacted fills
and backfills was performed after ASTM D6938 (‘In-Place Density and Moisture by Nuclear
Report of As-Graded Geotechnical and Geologic Conditions Hope Elementary School Modernization Phase 1, Carlsbad, CA NOVA Project No. 1020087

Methods’). The density of the asphaltic wearing surface of pavements was determined after
ASTM D2950 (‘Standard Test Method for Density of Bituminous Concrete by Nuclear
Methods’).
The approximate locations of the density tests conducted for this work are shown on the
attached plates. The laboratory test results are presented in Table I. The field in-place density
test results are summarized in Table II.
2. Laboratory Testing. The field density testing was supported by laboratory testing of
representative samples of soils utilized for fills, backfills, and pavement materials in
accordance with ASTM D1557. The test results are presented in Table I. The indications of
this testing are the basis for NOVA’s judgments regarding the relative compaction of the fills
placed.
3. Technical Support. Provided technical support in response to geotechnical-related issues that
arose during construction.
4. Reporting. Provided reporting during the conduct of the work. Submittal of this report completes
NOVA’s scope of services.
OBSERVED SOIL AND GEOLOGIC UNITS
General
The adequacy of earthwork was determined in part by observation of earthwork operations by
experienced soils technicians familiar with both the specific intent and specific requirements of this
project. This observation was the basis for selection by NOVA of locations for testing of density and
for recovery of samples for laboratory testing.
The following subsections provide discussion regarding NOVA’s observations of the geologic units.
Engineered Artificial Fill Placed by NOVA (af)
During grading, previously placed fills and excavated Santiago Formation were removed and replaced
as compacted engineered fill after ASTM D6938 (‘In-Place Density and Moisture by Nuclear
Methods’). All of this earthwork was the object of QA observation, testing, and technical support by
NOVA, as described above.
Santiago Formation (Tsa)
As reported in NOVA 2019 and encountered during grading operations in the field, the site is underlain
by medium to very dense formational sandstones of the Santiago Formation. These deposits generally
consisted of white to light gray silty sandstones.

CONSTRUCTION SUMMARY
General
Period of Work
Construction of relevance to this report was completed during the period July 20, 2020, to September
18, 2021.
Part-Time Surveillance
NOVA provided part-time observation of earthwork operations, as requested by the contractor. The
description of earthwork operations provided in the following subsections reflects observations by
NOVA during its presence on-site and may not reflect all work by the contractor.
Operations
The contractor was Erickson Hall Construction Co. The specialty earthwork subcontractor was Anton’s
Service, Inc. Electrical utilities were installed by Fredericks Electric, Inc. Wet utilities were installed by
Interpipe Contracting, Inc. Installment of pavements and pavement materials was completed by Post
Brothers Construction Co. and RAP Engineering, Inc.
The grading subcontractor utilized a variety of medium to heavy-duty equipment to perform the
earthwork. Equipment included: tracked dozers, graders, wheel loaders, backhoes, tracked
excavators, rollers, and sheepsfoot compaction wheels. Manually operated reciprocating hammers
were used where access to larger equipment was limited.
Site Preparation
Prior to earthwork operations, debris, topsoil, and vegetation in the areas being improved were
removed and disposed of off-site.
Site Buildings
Grading
Earthwork for all site buildings may be generalized to include the step-wise sequence of operations
described below.
1. Step 1, Removals. Soils were removed to an elevation of approximately 24 inches below the
bottom of footings wherever planned footing excavations were present in the areas receiving
the new building pad. Laterally, the removals extended outward of the planned improvements
at least 3 feet.
2. Step 2, Re-densification. Where the bottoms of removals probed firm and unyielding, the soils
were scarified to a depth of 12 inches and densified to 90% relative compaction after ASTM
D1557 (the ‘Modified Proctor’) in accordance with the project specifications.

3. Step 3, Replacement. Soils staged in Step 1 were replaced as compacted fill. The replaced
soils were moisture conditioned to near optimum moisture content and then spread in loose
lifts of typically 4 to 8 inches. Thereafter, the soils were densified to at least 90% relative
compaction after ASTM D1557 in accordance with the project specifications.
During grading for building pads ‘H’ and ‘K’, a zone of sandy clay was observed at the bottom of
removals in each of the pads. In these areas, one extra foot of the clayey material was removed (to 5
feet below finished pad grade), and the area was stabilized with 1 foot of compacted base prior to
commencing fill operations.
Figure 1 depicts the remedial excavations for building pad ‘G’. Figure 2 depicts the compaction of
placed fill for the backfill of the remedial excavations for building pad ‘J’.

Foundations
NOVA observed soils exposed during excavation for both isolated and continuous foundations for the
support of the classroom buildings (Buildings A, G, H, J, and K). The foundation excavations were
observed by NOVA to be properly dimensioned and embedded into proper bearing strata comprised
of engineered fill.
Lunch Shelter Structure
Earthwork for the lunch shelter structure may be generalized to include the step-wise sequence of
operations described below.
1. Step 1, Removals. Soils were removed to an elevation of approximately 4 feet below the
planned subgrade elevation in the areas receiving the new structure. Laterally, the removals
extended outward of the planned improvements at least 3 feet.
2. Step 2, Re-densification. Where the bottoms of removals probed firm and unyielding, the soils
were scarified to a depth of 12 inches and densified to 90% relative compaction after ASTM
D1557 (the ‘Modified Proctor’) in accordance with the project specifications.
3. Step 3, Replacement. Soils staged in Step 1 were replaced as compacted fill. The replaced
soils were moisture conditioned to near optimum moisture content and then spread in loose
lifts of typically 4 to 8 inches. Thereafter, the soils were densified to at least 90% relative
compaction after ASTM D1557 in accordance with the project specifications.

Foundations
NOVA observed soils exposed during excavation for the isolated foundations for the support of the
lunch shelter. The foundation excavations were observed by NOVA to be properly dimensioned and
embedded into proper bearing strata comprised of engineered fill.
Playground Structure
Cast-in-drilled hole (‘CIDH’) piles were installed for foundation support of the playground structure.
NOVA observed the drilling and installation of the CIDH piles and noted them to be minimally
dimensioned in accordance with the approved plans and reporting (NOVA 2019). The piles were
observed by NOVA to be founded in the proper bearing strata comprised of Santiago Formation (Tsa).
Figure 3 depicts drilling operations for the playground structure foundations.

Post Grading
Utilities
NOVA observed backfilling operations for several utility line trenches. Characteristically sandy utility
backfill was moisture conditioned to near optimum moisture content and compacted to at least 90%
relative compaction after ASTM D1557 using a manually operated reciprocating hammer. Figure 4
depicts the compaction of the utilities.

Figure 4. Utility Compaction (August 21, 2020)
Flexible Pavements
Areas of newly installed utility lines within existing driveways and walkways were subject to patching
with hot-mix asphalt. Pavements were also constructed within the campus for recreation use and for
walkways between structures. Construction of these flexible pavement sections included the
sequence of operations described below.
1. Step 1, Subgrade Preparation. Subgrade preparation for construction of paved areas
consisted of removing 2 feet of existing soils and scarifying the surficial soils, moisture
conditioning, and densification of the bottoms of removals. Where Santiago Formation was
exposed during removals, over-excavation to 2 feet was not required. In either case, soils
were then replaced and densified to a depth of 12 inches to at least 95% relative compaction
after ASTM D1557.
2. Step 2, Base Course. An approximately 4- to 6.5-inch-thick layer of recycled class II
aggregate base for driveways, recreational areas, and walkways was densified to at least
95% of the material’s maximum density.
3. Step 3, Wearing Surface. An approximately 3- to 4-inch-thick asphaltic wearing surface was
spread in loose lifts and densified by static rolling.
Figure 5 depicts Step 3 of the above-described paving operations.

Flatwork
Flatwork subgrade preparation consisted of performing excavations of approximately 12 inches of
soils from the planned finished grade elevations or to contact with Santiago Formation, whichever
occurred first. Exposed soils were then scarified, moisture conditioned, and densified to a depth of 12
inches to at least 90% relative compaction after ASTM D1557. Thereafter, soil was moisturized to near
optimum moisture content and then spread in loose lifts of typically 4 to 8 inches. Soils were then
densified to at least 90% relative compaction after ASTM D1557 in accordance with the project
specifications.

Limitations
Testing and Observation
This report presents opinions, information, and data relative to the earthwork at the subject site.
Representatives of NOVA conducted testing and made observations per the request of the contractor
during the progress of the construction to evaluate conformance with the project requirements. The
testing by NOVA indicates that the earthwork observed conforms with the project requirements for
placement and densification.
Results presented herein are only representative of the samples and areas tested. As with any
manufactured product, there are statistical variations in the uniformity of an earth fill and in the
accuracy of the test used to measure its qualities. As compared with other manufactured products,
earthwork usually has wider fluctuations in both the product and the test results. Variations in material
properties are inherent in any earthwork operation and should be expected at this site.
Survey
References to elevations and locations herein were based on surveyors or grade checker stakes in
the field and from the project grading plans prepared by FPL and Associates, Inc (FPLA 2019). NOVA
did not provide construction surveying services. NOVA has no opinion regarding the accuracy of the
elevations or surface geometry with respect to the approved plans.
Supervision
The presence of NOVA personnel during the work progress did not involve any direct supervision of
the contractor or their work forces. Professional and technical advice and recommendations were
provided to the owner during the conduct of the work, based upon NOVA’s observations and
evaluations.
