OBJECTIVES AND SCOPE OF NOVA’S SERVICES
Objectives
The objectives of NOVA’s services during earthwork for the above-referenced project were twofold,
namely: (i) to observe geologic conditions encountered, and (ii) through testing and observation, to
document that the earthwork/grading was completed in conformance with the permitted design
documentation.
Scope
In order to accomplish the above objectives, NOVA undertook the scope of services abstracted below
during the period of relevant construction.
1. Observation and Testing. NOVA performed observation and testing as requested by the
contractor during rough grade operations (removals and compaction). Quality Assurance
(QA) in-place density testing of soils placed as compacted fills and backfills were
performed after ASTM D6938 (‘In-Place Density and Moisture by Nuclear 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. NOVA provided 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.
CONSTRUCTION SUMMARY
General
Construction of relevance to this report was completed during the period of June 21, 2023 to
September 30, 2024.
The general contractor was C.W. Driver. The earthwork subcontractor was FJ Willert Contracting Co.
Wet and dry utilities were placed by HPS Plumbing, Southland Electric, and Urban Habitat. Pavement
materials were completed by Western Rim Construction.
NOVA provided observation of earthwork operations, at times requested by the contractor. The
description of earthwork operations provided in the following subsections reflects observations by
NOVA during its presence on-site.
Site Preparation
Prior to earthwork, debris in the areas being improved was removed and disposed of off-site.
Operations
The grading subcontractor utilized a variety of medium equipment to perform the earthwork.
Equipment included: front loaders, skip loaders, skid steers, tracked excavators with sheep foots
wheel attachment, and rollers. Manually operated reciprocating hammers and vibratory plates were
used for compaction where access to larger equipment was limited.
Wall Footings
Wall footings were excavated to planned bottom elevations. In areas where yielding or unsuitable
soils were exposed, excavation up to about 2 feet below planned footing bottom elevation was
performed. The excavated soils were then used as compacted fill. Backfill operations consisted of
placing soils that were moisture conditioned to near optimum moisture content in relatively thin,

uniform lifts. Backfill was densified to at least 90% relative compaction after ASTM D1557 (the
‘Modified Proctor’). Figure 1 depicts retaining wall footing excavation operations. NOVA observed the
footing excavations for retaining and seat walls to evaluate conformance with the project geotechnical
recommendations. The foundations consisted of continuous shallow spread footings. The foundations
were observed to be excavated to the planned depths and dimensions and embedded into suitable
bearing materials consisting of competent formational materials, previously placed slurry or
compacted fill.

Post Grading
Utilities
NOVA observed backfilling operations for several utility line trenches. Characteristically sandy utility
backfill was moisture conditioned to near optimum moisture content, placed and spread with skid
steers in multiple uniform lifts, and compacted to at least 90% relative compaction based on ASTM
D1557 using a sheepsfoot wheel attached to tracked excavators and manually operated reciprocating
tampers. Figure 2 depicts the compaction of a utility line.

Pavement Patching
Areas of newly installed utility lines and curbs within and surrounding the existing at-grade parking
area were subject to patching with hot mix asphalt. Construction of these flexible pavement sections
included the sequence of operations described below.
1. Step 1, Subgrade Preparation. Preparation of the subgrade for these areas included
backfill of utility line trenches and curb areas by placing moisture-conditioned fill to 90%
relative compaction and 95% for the upper 12 inches of subgrade after ASTM D1557 (the
‘Modified Proctor’) in accordance with the project specifications.
2. Step 2, Base Course. An approximate 10-inch-thick Class II aggregate base layer was
densified to at least 95% of the material’s maximum density.
3. Step 3, Wearing Surface. The approximately 4-inch-thick layer of the asphaltic wearing
surface was spread in loose lifts and densified by rollers and mechanical tampers.
Figure 3 depicts Step 3 of the above-described paving operations.

Concrete Flatwork
Concrete sidewalks and flatwork were constructed at the site. Beneath flatwork, the existing soils
were generally excavated to a depth of 12 inches below finished subgrade elevation. The exposed
soils were scarified, moisture conditioned to near optimum moisture content and compacted to at
least 90% relative compaction based on ASTM D1557.
Fill was moisture conditioned to near optimum moisture content and compacted to at least 90%
relative compaction based on ASTM D1557. Figure 4 depicts compaction of flatwork subgrade.

Testing and Observation
This report presents opinions, information, and data related to the earthwork at the subject site.
Representatives of NOVA conducted testing and made observations as requested by the contractor
during the progress of the construction to evaluate conformance with the project requirements. The
testing 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 at this site.
