1.2 SITE AND PROJECT DESCRIPTION
1.2.1 Location
The development encompasses Lot 12 of the Carlsbad Raceway Business Park. Lot 12 is located west of the intersection of Lionshead Avenue and Business Park Drive and directly west of the Vista Palomar Park shopping center on the south side of Lionhead Avenue in the City of Carlsbad, California.
1.2.2 Project Description
The principal element of the project consisted of the development of a new tilt-up constructed commercial building. The building is an approximately 89,000 square feet, single-story structure. The project construction included associated improvements such as loading docks, site retaining walls, detention basins, parking area and driveway pavements, and utilities.
1.3 PREVIOUS EARTHWORK AT THE SITE
The project site and all of the former Carlsbad Raceway Tracks were mass graded between August 19, 2004, and May 30, 2006. A record of that work is reported in “Final Report of Testing and Observation Services During Site Grading for Carlsbad Raceway Business Park, Lots 1 through 28, tract C.T. 98-10, Carlsbad, California, Project No. 07349-42-02, June 5, 2006 (hereafter ‘Geocon 2006’).
Previous mass grading at the site resulted in fills with a maximum thickness of about 35 feet in the majority of the lot with the exception of the northeastern and southern most portion of Lot 12. Geocon 2006 documents that fills were placed and compacted to at least 90 percent relative compaction after ASTM D1557 (‘Laboratory Compaction Characteristics of Soil Using Modified Effort’).
1.4 EARTHWORK AND DENSITY TESTING
1.4.1 General
Prior to the recent earthwork operations, debris, topsoil, and vegetation were removed and disposed of offsite from areas receiving new planned improvements.
1.4.2 Description of Operations
The grading contractor, F.J. Willert Contracting, and several utility contractors including C.E. Wilson Corporation, Collins Pacific Plumbing, Precision Electric, and Southland Paving utilized a variety of medium
to heavy size equipment to perform the earthwork. Equipment included: scrapers, graders, loaders, backhoes, dozers, excavators, sheepsfoot wheel compactors, rollers, and manually operated reciprocating hammers. NOVA provided observation of earthwork operations as requested by the General Contractor (TFW Construction). Quality Assurance (QA) in-place density testing was performed after ASTM D6938 (‘In-Place Density and Moisture by Nuclear Methods’) on materials placed as compacted fills and backfills. The approximate locations of field density tests are shown on the attached plates. The laboratory test results are presented in the attached Table I. The field in-place density test results are summarized in the attached Table II. Earthwork for the building consisted of cuts and fills to establish the building pad grade. Cuts for the building pad extended to about 11 feet below ground surface at the south end, decreasing to less than 1 foot at the center of the pad. Fills increased from the center of the pad to about 5 feet from grade at the northeast corner.
Due to the clayey nature of the existing material, select fill was placed within the upper 3 feet of the design building pad grade extending to at least 3 feet outside of the building footprint. The building pad was over
As-Graded Geotechnical Report Carlsbad Raceway Lot 12
August 23, 2018 NOVA Project No. 1017727
3
excavated as necessary to achieve the 3 feet of select fill subgrade. The soils in areas receiving new fills were scarified, moisture-conditioned and compacted to at least 90 percent relative compaction. New fills were placed in relatively thin lifts, moisture conditioned and compacted to at least 90 percent relative compaction after ASTM D1557 in accordance with the project specifications. A cut and fill transition existed in the building pad. At the surface, the northeastern portion of the building exposed Tertiary-aged Santiago Formation while the remaining areas exposed the previously placed compacted fills. As such, the northeastern cut portion of the pad was over-excavated about 3 feet. The removals extended a minimum of 3 feet laterally beyond building footprint. The bottoms of the removals were scarified, moisture conditioned, and densified to at least 90% relative compaction after ASTM D1557 (the ‘Modified Proctor’). The removed soils were replaced with relatively sandy compacted fill derived from the mined soils.
Retaining Walls
Six (6) retaining walls were included as part of the project improvements. Five (5) retaining walls (Walls A, B, C, D, and E) consisted of masonry (CMU) construction and ranged in height from about 3 feet to 9 feet. One (1) Keystone® mechanically stabilized earth (MSE) wall (identified as Wall #4) ranged in height from about 2 feet to 4 feet.
Retaining wall backfill operations consisted of soils that were moisture conditioned to near optimum moisture content, and placed in relatively thin, uniform lifts. Backfill was densified to at least 90% relative compaction after ASTM D1557. The field density test results are summarized in Table II.
Construction of ‘Wall E’ included the placement of a permanent sump pump located behind the wall in order to drain any seepage water collected along the eastern ascending slope.
NOVA did verify the presence of wall subdrains located near the base of the constructed retaining walls. NOVA was not asked to observe the installation of the subdrain system, the subdrain connections or outlet
locations.
Utility Trenches
NOVA observed the backfilling operations as requested for several utility line trenches where indicated. Backfill soils were moisture conditioned to near optimum moisture content and compacted to at least 90% relative compaction after ASTM D1557. Pavement
Prior to the placement of paving materials, subgrade preparations consisted of scarifying the surficial soils, moisture conditioning, and compacting the subgrade to at least 95 percent relative compaction. Paving materials consisted of aggregate base and asphalt concrete compacted to at least 95 percent of the material’s maximum density in accordance with ASTM D6938 and ASTM D2950 (Density of Bituminous Concrete In-
Place by Nuclear Methods), respectively.
Density Testing
In-place density and moisture content testing of compacted fills and backfills were performed by NOVA’s field representatives in accordance with ASTM D6938. The results of field density testing are summarized in Table II of Appendix A. The approximate locations of field density tests are shown on the attached figures. Laboratory Testing
The field density testing was supported by laboratory testing of representative samples of soils utilized for fills and backfills in accordance with ASTM D1557. The test results are presented in Table I of Appendix A. The

indications of this testing are the basis for NOVA’s judgments regarding the relative compaction of the fills placed.
1.5 OBSERVED SOIL AND GEOLOGIC CONDITIONS
The soil and geologic conditions observed during the grading operations were generally consistent with those described in NOVA’s Revised Report of Preliminary Geotechnical Investigation (NOVA 2017a) and Report of Supplemental Geotechnical Investigation (NOVA 2017b). Materials exposed during grading operations were found to be documented fill (Qaf) and Santiago Formation (Tsa).
1.6 CONCLUSIONS
Based on the observations and testing reported herein, it is NOVA’s opinion that the soil engineering and engineering geologic aspects of the grading are in compliance with the project grading plans and with the requirements of the City of Carlsbad, and the current edition of the California Building Code.
1.7 LIMITATIONS
This report presents information and data relative to the earthwork at the subject site. Representatives of NOVA conducted periodic testing and made observations during the progress of the construction as requested by the general contractor to evaluate conformance with the project requirements.
NOVA was not asked to observe or test wall backfills for Wall ‘D’; therefore, NOVA cannot comment on the performance of wall backfills for Wall ‘D’.
References to elevations and locations herein were based on surveyor or grade checker stakes in the field and from the project grading plans prepared by Excel Engineering (Excel 2017). 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.
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 provided to the owner and/or his designated representative based upon NOVA’s observations. Results presented herein are
only representative of the samples and areas tested. Variations in material properties are inherent in any earthwork operation.
1.8 CLOSURE
