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, by testing and observation, that the
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 construction.
1. Observation and Testing. NOVA performed observation and testing as requested by the
contractor during rough grade operations (removals and compaction) and post-grade
operations (utility backfill, paving, and flatwork). 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 Methods’) and ASTM D8167 (‘In-Place Density
and Moisture by Non-Nuclear Methods’). Testing of asphalt concrete was performed after
ASTM D2950 (‘In-Place Density of Bituminous Concrete by Nuclear Methods’).
The approximate locations of the density tests conducted for this work are shown on the
attached Plate. 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. 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. NOVA provided periodic technical support in response to geotechnical-
related issues during construction.

4. Reporting. NOVA provided reporting during the conduct of the work. Preparation 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
NOVA staff familiar with the requirements for earthwork in the Carlsbad area and 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.
NOVA’s observations during the grading excavation operations indicate that subsurface
conditions within the limits of excavation were generally consistent with those anticipated and
described in the approved geotechnical report (CWE 2016).
The following subsections provide detailed discussion regarding NOVA’s observations of the
geologic units and geologic structure encountered during mapping.
Artificial Fill (af)
The improvements are built entirely on engineered artificial fill (af). The purpose of the fill is to
provide a building pad of engineered soils for development of shallow foundations. Fill extends to
a depth of approximately +55 feet msl.
Old Paralic Deposits (Qop)
Old paralic deposits were observed to consist of moist, relatively dense, silty sand. No
groundwater was encountered.
CONSTRUCTION SUMMARY
General
NOVA provided 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.
Construction of relevance to this report was completed during the period of October 20, 2020 to
May 19, 2021.
The contractor was HA Builders. The specialty earthwork subcontractor was Whillock Contracting.
Utilities were installed and backfilled by Ranbar Plumbing. Pavements and pavement materials
were completed Frank and Son Paving and Xpress Concrete. Hardscapes and respective
subgrade and base preparation was completed by Frank and Son Paving.

EARTHWORK
Site Preparation
Prior to earthwork operations, older fill, debris, topsoil, and vegetation in the areas being improved
were removed and disposed of off-site.
Operations
The grading subcontractor utilized a variety of medium to heavy-duty equipment to perform the
earthwork. Equipment included: wheel loaders scrapers, graders, backhoes, tracked excavators,
rollers, and sheepsfoot compaction wheels. Manually operated reciprocating hammers and walk
behind rollers were used where access to larger equipment was limited.
Building Pad
Grading
Earthwork consisted of remedial grading to prepare a suitable building pad and may be
generalized to have included the stepwise sequence of operations described below.
1. Step 1, Over Excavation. The existing engineered fill was excavated to a depth of 55 to
msl and extended laterally about 5 feet outside of the building limits, where feasible. Excavated soils were staged for later replacement.
2. Step 2, Densification. A representative from NOVA approved the bottom of excavations exposed by Step 1. The bottoms of the removals were scarified, moisturized and compacted prior to placing fills.
3. Step 3, Backfill. Excavated soils were backfilled consistent to the material and placement requirements described in CWE 2016. Backfill was moisture conditioned to near optimum moisture content and compacted to at least 90% relative compaction after D1557.
Utilities
NOVA observed backfilling operations for several utility line trenches. Site sourced or imported
characteristically sandy utility backfill was moisture conditioned to near optimum moisture content
and compacted to at least 90% relative compaction using manually operated reciprocating
hammers and a sheepsfoot wheel attached to a tracked excavator.
Flatwork/Pavers
Subgrade preparation for flatwork and pavers consisted of scarifying the upper 12 inches of
existing soils, and replacing the excavated soils as new fill densified to at least 95% relative
compaction.

Right-of-Ways
Utility tie-in and pavement patches within the city right-of-ways (ROW) were prepared in the
general sequence of operations described below.
1. Step 1, Utility Tie-In Backfill. NOVA observed backfilling operations for several utility line trench tie-ins within the City Right-of-Ways. Characteristically site sourced or imported sandy utility backfill was moisture conditioned to near optimum moisture content and
compacted to at least 90% relative compaction using manually operated reciprocating hammers and a sheepsfoot wheel attached to a tracked excavator.
2. Step 2, Subgrade Preparation. Subgrade soils were scarified about 12 inches, moisture
conditioned, and compacted to at least 95% relative compaction.
3. Step 3, Base Course. An approximate 8- to 12-inch-thick layer of aggregate base was
placed and densified to at least 95% of the material’s maximum density.
4. Step 4, Wearing Surface. An approximate 5- to 6-inch-thick section of the asphaltic
wearing surface within Oak Avenue was placed in lifts and densified by a vibratory roller.
Pavement surface asphalt patches were eventually milled about 1 to 3 inches and repaved
with new hot mix asphalt concrete densified to at least 95 percent relative compaction.
Foundations
NOVA observed soils exposed during excavation for both isolated and continuous foundations for
the support of the planned structure and for ancillary site walls with exception of property boundary
walls/fences.
At the time of observation, the foundation excavations were observed to be minimally
dimensioned with the geotechnical recommendations and embedded into a proper bearing
stratum comprised of compacted fill observed and testing by NOVA.
CONCLUSIONS AND LIMITATIONS
Conformance with Design
Based on the observations and testing reported herein, NOVA certifies that the soil engineering
and engineering geologic aspects of the grading have been completed in conformance with the
requirements of the approved geotechnical reports and the grading plans (Drawing#5234A).
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 as requested during the
progress of the construction to evaluate conformance with the project requirements. The testing
6
As-Graded Geotechnical Report Windsor Point – Harding St, Carlsbad, CA NOVA Project No. 4020055
June 20, 2022
by NOVA indicates that the earthwork observed conformance 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 has usually wider fluctuations in both the product and the test results. Variations in
material properties are inherent in any earthwork operation and should be expected.
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 KLE 2020. 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 his work forces. Professional and technical advice and recommendations were periodically provided to the owner during the conduct of the work, based upon NOVA’s observations and evaluations.
