GENERAL The general contractor for the project was OSL Construction, Inc. The grading contractor for the project was Green Wave Contractors. The project grading plans were prepared by Alliance Land Planning and Engineering, Inc., titled Grading Plans For: Oakmont of Carlsbad, dated July 6, 2020. Recommendations for the grading were provided in our referenced report (Reference No. 1). The exhibit used as a base map to present the as-graded geologic information and density test locations (Figure 1) is a reproducible copy of a compilation of digital information provided by Alliance Land Planning and Engineering, Inc. The map depicts the structure footprints, and existing and proposed improvements. We added the approximate locations of the field density tests performed during grading and geologic contacts. References to elevations and locations herein are based on as-graded survey information obtained from grade checkers’ stakes in the field. Geocon Incorporated does not provide surveying services and, therefore, has no opinion regarding the accuracy of the as-graded elevations or surface geometry with respect to the approved grading plans or proper surface drainage. GRADING Grading began by removing and exporting brush and vegetation from the areas to be graded. Grading for Building Pads 1 and 2 consisted of removing previously-placed fill to expose competent granitic rock or competent previously-placed fill in the basement level. Grading for Building Pad 3 consisted of scarifying, moisture-conditioning, and compaction of the upper 1-foot of previously placed compacted fill prior to additional fill placement. Grading outside the building pads generally consisted of scarifying, moisture conditioning, and compacting the previously placed fill. Fill soils derived from on-site excavations were then placed and compacted in layers until the design elevations were attained. The maximum thickness of compacted fill placed during grading and building wall backfill was approximately 10 feet. The grading was performed in conjunction with testing and observation services provided by Geocon Incorporated. Project No. 06442-32-29A - 3 - February 2, 2022 As requested by the City of Carlsbad, we prepared several pad certification letters (References 2 through 4) summarizing the as-graded conditions beneath the building pads prior to building construction. Fill Materials and Placement Procedures The on-site fill materials generally consisted of silty, fine to coarse sand, sandy silt, and silty clay. The fills were placed in lifts no thicker than would allow for adequate bonding and compaction. The soil was moisture conditioned as necessary and mixed during placement. Field In-Place Density and Laboratory Testing During the grading operation, compaction procedures were observed and in-place density tests were performed to evaluate the relative compaction of the fill material. The in-place density tests were performed in general conformance with ASTM D 6938 (nuclear). Results of the field density tests and moisture content tests performed during grading are summarized on Table I. The approximate locations of the field density tests performed during grading and building wall backfill operations are shown on the As-Graded Geologic Map. In general, the in-place density test results indicate that the fill at the locations tested has a relative compaction of at least 90 percent and near or slightly above optimum moisture content. Laboratory tests were performed on samples of material used for fill to evaluate moisture-density relationships, optimum moisture content and maximum dry density, expansion potential and water soluble sulfate content. The results of the laboratory tests are summarized on Tables II through IV. Finish-Grade Soil Conditions Observations and laboratory test results performed during the grading operations indicate that the prevailing soil conditions within three feet of finish grade have an Expansion Index of less than 90 and are classified as having a “low” to “medium” expansion potential. However, some highly expansive soils are present on-site. In general, the majority of the site consists of compacted fill over granitic rock. The fill generally consists of a soil with maximum 6-inch size rock. SOIL AND GEOLOGIC CONDITIONS The soil and geologic conditions encountered during grading were found to be generally similar to those described in the referenced project geotechnical report, except that we are mapping the Project No. 06442-32-29A - 4 - February 2, 2022 formational material beneath the property as granitic rock instead of Point Loma Formation due to our observations once the entire excavation was exposed. The geologic conditions observed during grading are presented on the As-Graded Geologic Map. IMPROVEMENTS In accordance with your request, we have provided testing and observation services for underground utility and surface improvements. Our services were provided on an “on-call” basis between July 15, 2020 and January 28, 2022. The scope of our services consisted of performing in-place density tests on a “call out” basis during backfill for retaining walls and underground improvements, consisting of sewer, water, fire service, and joint trench and preparation of subgrade for curb/gutter, sidewalks, and interior roadways. We also performed in-place density tests during preparation of off-site street (Faraday Avenue) subgrade and placement of aggregate base and asphalt concrete pavement. In-place density tests were performed using a nuclear gauge in accordance with ASTM Test Procedure D 6938. Laboratory compaction tests were performed on soil samples in accordance with ASTM Test Procedure D 1557. The results of the field tests are summarized on Table I and the results of the laboratory maximum dry density/optimum moisture content tests are summarized in Table II. Laboratory tests on asphalt concrete samples were performed in accordance with ASTM Test Procedures D 2726 Hveem Density; D 2041 Theoretical Maximum Density; D 1560 Stability; D 6307 Asphalt Content; and C 136 Sieve Analysis for Asphalt. The laboratory test results are shown on Tables III through V. Results of the in-place density tests indicates that retaining wall backfill, sidewalk subgrade and trench backfill materials possess a dry density of at least 90 percent of the laboratory maximum dry density near to slightly above the optimum moisture contents at the locations tested. Similarly, in- place density test results for roadway subgrade and aggregate base materials indicated a dry density of at least 95 percent of the laboratory maximum dry density at the locations tested, except as noted below. In-place density test results for the asphalt concrete indicates a density of at least 95 percent of the laboratory Hveem density. On January 6, 2022, we observed and tested three isolated roadway subgrade areas that were yielding due to wet soil conditions. At that time, the contractor decided to leave these areas unmitigated. On January 17, 2022, we again observed the subgrade in these areas to yield due to over optimum moisture contents and our test results generally indicated 90 percent relative compaction or greater instead of 95 percent. The contractor removed portions of the wet materials but the remedial work was limited due to existing utilities. Aggregate base was placed in the depressions and compacted. Project No. 06442-32-29A - 5 - February 2, 2022 The upper approximately 1-foot of aggregate base exhibited at least 95 percent relative compaction prior to placing asphalt concrete. CONCLUSIONS AND RECOMMENDATIONS 1.0 General Based on observations and test results, it is the opinion of Geocon Incorporated that the grading and improvement construction has been performed in substantial conformance with the recommendations of the referenced project soil report. Soil and geologic conditions encountered during grading which differ from those anticipated by the project soil report are not uncommon. Where such conditions required a significant modification to the recommendations of the project soil report, they have been described herein. 2.0 Future Grading and Improvements Any additional grading or planned improvements performed at the site should be accomplished in conjunction with our geotechnical services. Plans for any future improvements should be reviewed by Geocon Incorporated prior to finalizing. Any additional trench backfill in excess of 1-foot-thick should be compacted to at least 90 percent relative compaction. This office should be notified at least 48 hours prior to commencing additional grading or backfill operations. 3.0 Slope Maintenance Slopes that are steeper than 3:1 (horizontal:vertical), under conditions which are both difficult to prevent and predict, may be susceptible to near surface slope instability. The instability is typically limited to the outer three feet of a portion of the slope and does not directly impact the improvements on the pad areas above or below the slope. The occurrence of surficial instability is more prevalent on fill slopes and is usually preceded by a period of heavy rainfall, excessive irrigation, or the migration of subsurface seepage. The disturbance and/or loosening of the surficial soils, as might result from root growth, soil expansion, or excavation for irrigation lines and slope planting, may also be a significant contributing factor for surficial instability. It is, therefore, recommended that, to the maximum extent practical: (a) disturbed/loosened surficial soils be either removed or properly recompacted, (b) irrigation systems be periodically inspected and maintained to eliminate leaks and excessive irrigation, and (c) surface drains on and adjacent to slopes be periodically maintained to preclude ponding or erosion. It should be noted that although the incorporation of the above recommendations should reduce the potential for surficial slope instability, it will not eliminate the possibility, and, therefore, it may be necessary to rebuild or repair a portion of the project's slopes in the future. Project No. 06442-32-29A - 6 - February 2, 2022 4.0 Drainage Adequate drainage provisions are imperative. Under no circumstances should water be allowed to pond adjacent to footings. The building pads should be properly finish graded after the building and other improvements are in place so that drainage water is directed away from foundations, pavements, concrete slabs, and slope tops to controlled drainage devices. LIMITATIONS The conclusions and recommendations contained herein apply only to our work with respect to grading and improvements and represent conditions at the date of our final observation on January 28, 2022 Changes in the conditions of a property can occur with the passage of time due to natural processes or the works of man on this or adjacent properties. In addition, changes in applicable or appropriate standards may occur, resulting from legislation or the broadening of knowledge in the fields of geotechnical engineering or geology. Accordingly, the findings of this report may be invalidated wholly or partially by changes outside our control. Therefore, this report is subject to review and should not be relied upon after a period of three years. Any subsequent grading should be done in conjunction with our observation and testing services. As used herein, the term "observation" implies only that we observed the progress of the work with which we agreed to be involved. Our services did not include the evaluation or identification of the potential presence of hazardous or corrosive materials. Our conclusions and opinions as to whether the work essentially complies with the job specifications are based on our observations, experience and test results. Due to the inaccuracies inherent in most field and laboratory soil tests, and the necessary assumption that the relatively small soil sample tested is representative of a significantly larger volume of soil, future tests of the same soil, location or condition should not be expected to duplicate specific individual test results of this report. Subsurface conditions, and the accuracy of tests used to measure such conditions, can vary greatly at any time. We make no warranty, express or implied, except that our services were performed in accordance with engineering principles generally accepted at this time and location. We will accept no responsibility for any subsequent changes made to the site by others, by the uncontrolled action of water, or by the failure of others to properly repair damages caused by the uncontrolled action of water. It is the responsibility of OSL Construction to ensure that the information and recommendations contained herein are brought to the attention of the architect and civil engineer for the project, and are incorporated into the plans, and that the necessary steps are taken to see that the contractor and subcontractors carry out such recommendations in the field. Recommendations that pertain to the future maintenance and care for the property should be brought to the attention of the facilities department or entity responsible for future maintenance.
