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 Report of As-Graded Geotechnical and Geologic Conditions Valley Middle School Campus Modernization, Carlsbad, California NOVA Project No. 1023128 September 11, 2025 3 (‘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, Report of As-Graded Geotechnical and Geologic Conditions Valley Middle School Campus Modernization, Carlsbad, California NOVA Project No. 1023128 September 11, 2025 4 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. Figure 1. Retaining Wall Footing (May 2, 2024) 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. Report of As-Graded Geotechnical and Geologic Conditions Valley Middle School Campus Modernization, Carlsbad, California NOVA Project No. 1023128 September 11, 2025 5 Figure 2. Utility Line Compaction (July 18, 2023) 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.

Paving Operations (August 12, 2023) 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.

Flatwork Subgrade Operations (June 6, 2024) LIMITATIONS Limitations 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.
