(7,4, S*. >*»* SOILS INVESTIGATION Introduction This is to present- the result of a soils investigation conducted at the site of a proposed west end addition to the existing Health Spa Building located northwesterly of the intersection of Costa Del Mar and Estrella De Mar at Rancho La Costa in Carlsbad, California. The objectives of this invesfigation were to derermine the existing soil conditions and physical properties of the soils in order that recommendations for the safe and economica! design of foo'rings for the proposed addition may be presented. In order to accomplish these objectives, three borings were drilled, undisturbed and loose soil samples were obtained for laboratory testing. Field investigation The three borings were drilled 30 inches in diameter with a truck-mounted rotary bucket- rype drill rig at the approximate locations shown on the attached Drawing No. 1, entitled "Loc- arion of Test Borings" that was revised to show the recent borings. Also shown on this drawing are the locations of four borings previously drilled and included in our report under Project No. 64-1 0-9A. The three recent borings were drilled to a depth of 15.0 feet below the existing ground surface. A continuous log of the soils encountered in these borings was recorded at the time, of drilling and is shown in detail on Drawing Nos. 2 to 4, inclusive, each entitled "Summary Cheat." -2- The soils were visually classified by field identification procedures in accordance wifh the Unified Soil Classification Chart. A simplified description of this classification system is presented in the attached Appendix A at the end of this report. Undisturbed samples were obtained at frequent intervals in the soils ahead of the drilling. The drop weight used for driving the sampling tube into the soils was the "Kelly" bar of the drill rig which weighs 2200 pounds, and the average drop was 12 inches. The general procedure used in field sampling are described under "Sampling" in Appendix B. Laboratory Tests Laboratory tests were performed on all undisturbed samples of the soils in order to deter- mine the dry density and moisture content. The results of these tests are presented on Drawing Nos. 2 to 4, inclusive. Consolidation tests were performed on representative samples in order to determine the load-settlement characteristics of the soils and the results of these tests are pre- sented graphically on Drawing No. 5 entitled "Consolidation Curve." Direct shear tests were performed on selected undisturbed samples that were all saturated and drained prior to testing. The results of these tests are presented below: Boring 1 , Sample 1 Depth: 2.0 Feet Boring 2 , Sample 1 Depth: 2.0 Feet Normal Load in kips/sq ft 0.5 1.0 2.0 0.5 1.0 2.0 Maximum Shear Load kips/sq ft 0.54 1.12 1.34 4.23 5.41 5.21 Angle of Internal Friction Degrees 28.0 33.0 Apparent Cohesion Ib/sq ft 280 3900 BENTON ENGINEERING INC -3- The general procedures used for the laboratory tests are described briefly In Appendix B. Compaction tests were performed on representative samples of the soils below existing fills to establish compacfion criteria. The soils were tested according to the A.S.T.M. D 1557-70 method of compaction which uses 25 blows of a 10 pound rammer dropping 18 inches on each of 5 layers in a 4 inch diameter 1/30 cubic foot mold. The results of the tests are presented as follows: Maximum Optimum Mois- Boring Bag Depth Soil Dry Density ture Content No. Sample in Feet Description Ib/cu ft % dry wt 1 2 2.0-3.0 Silty fine sand with 123.3 11.0 some clay binder DISCUSSION,CONCLUSIONS AND RECOMMENDATIONS Soil Strata At Boring 1, a medium firm fill was found underlying a 2-inch thickness of asphalr pavemenf to a deprh of 1.0 Foot. The fill soils consisted of clayey fine to medium sand and the mixture of clayey fine sand and fine sandy clay. The fill was underlain by a medium firm silry fine sand with clay binder to 3.7 feet in depth and merged to compact slightly silty fine sand to the end of boring 15.0 feet. At Boring 2, a 2-inch thickness of asphalt pavement was underlain by a medium firm clayey fine to medium sand and fine to medium sandy clay fill to a depth of 1.5 feet. Below this depth, a very firm clayey fine sand was found to 2.8 feet in depth that was underlain by a very compact slightly silry fine to medium sand to 3.7 feet and by a very compact fine to coarse sand to a depth of 8.5 feet. Below 8.5 feet, a very compact and slightly clayey fine to coarse send with approximately 10 to 25 percent gravel to 2 inches in diameter was found to a depth of 13,0 feet and then merged to very firm silty fine sand to 14.0 feet that was underlain by a very compact slightly silty fine sand to the end of boring ar 15.0 feer. BENTON ENGINEERING INC -4- At Boring 3, a soft to medium firm clayey fine sand was found to a depfh of! .5 feet. This was underlain by a compact gravelly fine to coarse sand to 3.5 feet, a very compact fine to coarse sand to 6.0 reef, a very compact gravelly slightly clayey fine to coarse sand to 12.0 feet, and then merged to very compact and slightly silty fine sand to the end of boring at 15.0 feet. No ground water was encountered in any of the borings drilled. Conclusions it is concluded from the results of field explorations and laboratory rests that the pro- posed construction site is covered with an existing fill to the depths of 1.0 foot and 1.5 feet, respectively, in the areas of Borings 1 and 2. Also, a soft topsail of clayey fine sand was found to a depth of 0.5 foot in the areas of Boring 3. These existing fill soils and the soft topsoils are unsuitable for footings under present conditions. Recommendations 1 . Foundation Bearing Soils It is recommended that all footings be deepened through the existing fills and the soft topsoils, and be placed at least one foot into the underlying bearing soils. The recommended bearing soils are the medium firm silty fine sand found below a depth of 1.0 foot in the area of Boring 1, the very firm clayey sand found below a depth of 1.5 feet In the area of Boring 2 and the medium firrr clayey fine sand found below a depth of 0.5 foot in the area of Boring 3. 2. Allowable Bearing Values Allowable bearing values of 3500 pounds per square foor and 2200 pounds per square foot may be used for a 2-foot wide square footing and a 1-foot wide continuous footing, respect- ively, rhat are placed 1 foot into the recommended bearing soils. The recommended minimum widths of square footing and continuous footing are 1 foot and 2 feet, respectively. The allow- able bearing values may be Increased at a rate of 400 pounds per square foot for each additional BENTON ENGINEERING INC foot of depth below 1 fool' for both types of footings. For each additional foot of width at the same elevations, the allowable bearing values may be increased at the rates of 100 pounds per square foot and 120 pounds per square foot, respectively, for the square footings and the con- tinuous footings. The recommended maximum allowable bearing value is 4500 pounds per square foot for both types of footings. The bearing values are for dead plus live loads and may be in- creased one-third for combined dead, live and seismic loadings. 3. SetMements Laboratory test results indicate that total settlements oF a one foot wide continuous footing end a 2-foot wide square footing placed and designed as recommended are estimated to be on the order of 1/8 inch and 1/4 inch, respectively. 4. Grading and Concrete Slab at Grade In view of the fact that there is a difference in elevation of approximately 3 feet between Boring 1 area in the north and Borings 2 and 3 areas in the south, it is assumed that some grading will be required to provide a level base for the floor slabs on ground. It is not known whether grading plans contemplate cutting the higher ground, or filling the lower ground, in either case, it is recommended that the existing asphalt concrete pavement be removed. Also, the upper ex- isting fills found in the areas of Borings 1 and 2, and the upper 0.5 foot of soft topsoil in the area of Boring 3 should be removed. In the fill area, the exposed surface should be scarified to a depth of 0.5 foot,moistened or dried as necessary to optimum, and then be recompacted with the excavated soils augumented by select nonexpansive soils properly compacted to 90 percent of the maximum dry density per A.S.T.M. D 1557-70 method of compaction to proposed finished grade. This method of compact- ion requires the use of 25 biows of a 10 pound hammer falling from a height of 18 Inches on each of 5 layers in a 4 inch diameter mold. Only those excavated soils that are free from asphalt con- crete fragments and ars nonexpansive should be recompacted under the proposed building prism. BENTON ENGINFERING INC -6- !n the cut area, the exposed excavated surfaces should also be scarified to a depth of 0.5 foot below proposed subgrade elevation, and should be compacted to at least 90 percent of maximum dry density. If the site is so prepared, concrete slabs at grade may be placed directly upon the nonexpansive compacted filled ground or the in-place nonexpansive soils comparabie to the re- commended bearing soils. The concrete slabs on grade may be reinforced with 6x6 - 10/10 welded wire fabric, if this is considered desirable from the structural standpoint to reduce the possibility of cracking. It is recommended that the select nonexpansive soils meet the following criteria: (a) It shall be a silty sand, clayey sand, or sand soil type. (b) It shail have no more than 40 percent passing the No. 200 sieve size. Also, at least 50 percent shall pass the No. 4 sieve size and it shall contain no gravel larger than 3 inches. (c) T^e expansion of a one inch high sample of the minus No. 10 material remolded to 90 percent of maximum dry density and then air dried for two days at 105 F, then loaded to 150 pounds per square foot and sat- urated, shall not exceed two percent. (d) The soil when compacted to 90 percent of maximum dry density shall have an allowable bearing value of not less than 2000 pounds per square foot for foofings placed 1 foot below the lowest adjacent final compacted ground surface. The grading operations should be conducted under continuous engineering inspection and be in accordance with the applicable sections of the attached Appendix AA, entitled "Standard Specifications For The Placement Of Compacted Filled Ground." BENTON ENGINEERING INC -7- 3. FooHngs In Compacted None>cpans?ve Filled Ground Footings may also be placed partly In the compacted nonexpanstve filled ground and part!/ in the in-piace recommended bearing soils if proposed finished grades require sufficient thickness of filled ground above existing grade. An allowable bearing value of 2000 pounds per square foot may be used for footings placed 1 foot below the lowest adjacent final compacted filled ground if the compacted filled ground is placed as recommended and the minimum widths of both square footing and continuous footing described in Section 1 are maintained. If footings are ro be supported partly by the in-place natural soils and partly by the compacted filled ground, then all exterior and interior footings should be reinforced and interconnected continuously with steel bars In order to minimize differentia! movements between the portions supported on com- pacted fiils and those poitions supported by the natural soils. 4. Lateral Resistance Lateral forces exerted on the structure by wind and seismic forces may be resisted by sliding friction on the bottom of the footings in connection with the passive pressures developed by I he soils around the footings. The safe passive resistance on the sides of footings cast against undisturbed in-place soils may be assumed to be equal to 460 pounds per square foot at the sur- face of bearing soils and may be increased at a rate of 135 pounds per square foot for each addi- tional foot of depth into the bearing soils. For footings placed in the compacted filled ground, en allowable bearing value of 200 pounds per square foot may be used at a depth of 1.0 foot below the lowest adjacent compacted final ground and this may be increased at a rate of 200 pounds per square foot for each additional foot of depth below 1.0 foot. BENTON ENGINEERING INC -8- A fricHonal coefficient of 0.4 may be used for friction berween rhe bottoms of concrete footings and the support-ing ?n-p!ace soils or compacted fills.

General Description. The objective is to obtain uniformity and adequate internal strength in filled ground by proven engineering procedures and tests so that the proposed structures may be safely supported The procedures include the clearing and grubbing, removal of existing structures, preparation of land to be filled, filling of the land, the spreading, and compaction of the filled areas to conform with the lines, grades, and slopes as shown on the accepted plans. The owner shall employ a qualified soils engineer to inspect and test the filled ground as placed to verify the uniformity of compaction of filled ground to the specified 90 percent of maximum dry density. The soils engineer shall advise the owner and grading contractor immediately if any unsatisfactory conditions are observed to exist and shall have the authority to reject the compacted filled ground until such time that corrective measures are taken necessary to comply with the specifications. It shall be the sole responsibility of the grading contractor to achieve the specified degree of compaction. 2. Clearing, Grubbing, and Preparing Areas to be Filled. (a) All brush, vegetation and any rubbish shall be removed, piled, and burned or other- wise disposed of so as to leave the areas to be filled free of vegetation and debris. Any soft, swampy or otherwise unsuitable areas shall be corrected by draining or removal, or both. (b) The natural ground which is determined to be satisfactory for the support of the filled ground shall then be plowed or scarified to a depth of at least six inches (6"), and until the surface is free from ruts, hummocks, or other uneven features which would tend to prevent uniform compaction by the equipment to be used. (c) Where fills are made on hillsides or exposed slope areas, greater than 10 percent, horizontal benches shall be cut into firm undisturbed natural ground In order to provide both lateral and vertical stability This is to provide a horizontal base so that each layer is placed and compacted on a horizontal plane. The initial bench at the toe of the fill shall be at least 10 feet in width on firm undisturbed natural ground at the eleva- tion of the toe stake placed at the natural angle of repose or design slope. The soils engineer shall determine the width and frequency of all succeeding benches which will vary with the soil conditions and the steepness of slope APPENDIX AA -2 - (d) After the natural ground has been prepared, if shall then be brought to the proper mois- ture content and compacted to not less than ninety percent of maximum density in accordance with A.S.T.M. D-1557-66T method that uses 25 blows of a 10 pound hammer falling from 18 inches on each of 5 layers in a 4" diameter cylindrical mold of a l/30th cubic foot volume 3 Materials and Special Requirements The fill soils shall consist of select materials so graded that at least 40 percent of the material passes a No. 4 sieve This may be obtained from the excavation of banks, borrow pits of any other approved sources and by mixing soils from one or more sources. The material uses shall be free from vegetable matter, and other de- leterious substances, and shall not contain rocks or lumps of greater than 6 inches in diameter. If excessive vegetation, rocks, or soils with inadequate strength or other unacceptable physical characteristics are encountered, these shall be disposed of in waste areas as shown on the plans or as directed by the soils engineer If during grading operations, soils not encountered a'nd tested in the preliminary investigation are found, tests on these soils shall be performed to determine their physical characteristics. Any special treatment recommended in the preliminary or subsequent soil reports not covered herein shall become an addendum to these specifications. The testing and specifications for the compaction of subgrade,subbase, and base materials for roads, streets, highways, or other public property or rights-of-way shall be in accordance with those of the governmental agency having jurisdiction 4 Placing, Spreading, and Compacting Fill Materials (a) The suitable fill material shall be placed in layers which, when compacted shall not exceed six inches (6"). Each layer shall be spread evenly and shall be throughly mixed during the spreading to insure uniformity of material and moisture in each layer. (b) When the moisture content of the fill material is below that specified by the soils engineer, water shall be added until the moisture content is near optimum as specified by the soils engineer to assure thorough bonding during the compactirg process. (c) When the moisture content of the fill material is above that specified by the soils engineer, the fill material shall be aerated by blading and scarifying or other satis- factory methods until the moisture content is near optimum as specified by the soils engineer (d) After each layer has been placed, mixed and spread evenly, it shall be thoroughly compacted to not less than ninety percent of maximum density in accordance with A S.T.M. D-1557-66T modified as described in 2 (d) above Compaction shall be accomplished with sheepsfoot rollers, multiple-wheel pneumatic-tired rollers, or other approved types of compaction equipment, such as vibratory equipment that is specially designed for certain soil types Rollers shall be of such design that *hey will be able BENTON ENGINEERING, INC. APPENDIX AA ( -3- fo compact tfie fill material to fhe specified density. Rolling shall be accomplished while the fill material is at the specified moisture content. Rolling of each layer shall be continuous over Its entire area and the roller shall make sufficient trips to insure that the desired density has been obtained. The entire areas to be filled shall be compacted . (e) Fill slopes shall be compacted by means of sheepsfoot rollers or other suitable equipment. Compacting operations shall be continued until the slopes are stable but not too dense for planting and until there is no appreciable amount of loose soil on the slopes. Compacting of the slopes shall be accomplished by backrolling the slopes In Increments of 3 to 5 feet In elevation gain or by other methods producing satisfactory results. (f) Field density tests shall betaken by the soils engineer for approximately each foot In elevation gain after compaction, but not to exceed two feet in vertical height between tests. Field density tests may be taken at intervals of 6 inches in elevation gain if required by the soils engineer. The location of the tests in plan shall be so spaced to give the best possible coverage and shall be taken no farther apart than 100 feet. Tests shall be taken on corner and terrace lots for each two feet in elevation gain. The soils engineer may take additional tests as considered necessary to check on the uniformity of compaction. Where sheepsfoot rollers are used, the tests shall be taken In the com- f. pacted material below fhe disturbed surface. No additional layers of fill shall be spread i until the field density tests indicate that the specified density has been obtained. (g) The fill operation shall be continued In six Inch (6") compacted layers, as specified above, until the fill has been brought to the finished slopes and grades as shown on the accepted plans. 5. Inspection. Sufficient Inspection by the soils engineer shall be maintained during tfie flliing and compacting operations so that he can certify that the fill was constructed in accordance with the accepted specifications. 6. Seasonal Limits. No fill material shall be placed, spread, or rolled if weather conditions increase the moisture content above permissible limits. When the work is interrupted by rain, fill operations shall not be resumed until field tests by the soils engineer indicate that the moisture content and density of the fill are as previously specified. 7. Limltlrg Values of Nonexpansive Soils. Those soils that expand 2.5 percent or less from air dry to saturation under a unit load of 500 pounds per square foot are considered to be nonexpanslve. 8. All recommendations presented in the "Conclusions" section of the attached report are a part of these specifications. BENTON ENGINEERING. INC. BENTON ENGINEERING, INC.

APPLIED SOIL MECHANICS FOUNDATIONS 6717 CONVOY COURT SAN DIEGO CALIFORNIA 92111 PHILIP HENKING BENTON PRESIDENT CIVIL ENGINEER TELEPHONE ( 714 > 389-1998 APPENDIX B Sampling The undisturbed soil samples are obtained by forcing a special sampling tube into the undisturbed soils at the bottom of the boring, at frequent intervals below the ground surface. The sampling tube consists of a steel barrel 3.0 inches outside diameter, with a special cutting tip on one end and a double ball valve on the other, and with a lining of twelve thin brass rings, each one inch long by 2.42 inches inside diameter. The sampler, connected to a twelve inch long waste barrel, is either pushed or driven approximately 18 inches into the soil and a six inch section of the center portion of the sample is taken for laboratory tests, the soil being still confined in the brass rings, after extraction from the sampler tube. The samples are taken to the laboratory in close fitting waterproof containers in order to retain the field moisture until completion of the tests. The driving energy is calculated as the average energy in foot-kips required to force the sampling tube through one foot of soil at the depth at which the sample is obtained. Shear Tests The shear tests are run using a direct shear machine of the strain control type in which the rate of deformation is approximately 0.05 inch per minute. The machine is so designed that the tests are made without removing the samples from the brass liner rings in which they are secured. Each sample is sheared under a normal load equivalent to the weight of the soil above the point of sampling. In some instances, samples are sheared under various normal loads in order to obtain the internal angle of friction and cohesion. Where considered necessary, samples are saturated and drained before shearing in order to simulate extreme field moisture conditions. Consolidation Tests The apparatus used for the consolidation tests is designed to receive one of the one inch high rings of soil as it comes from the field. Loads are applied in several increments to the upper surface of the test specimen and the resulting deformations are recorded at selected rime intervals for each increment. Generally, each increment of load is maintained on the sample until the rate of deformation is equal to or less than 1/10000 inch per hour. Porous stones are placed in contact with the top and bottom of each specimen to permit the ready addition or release of water. Expansion Tests One inch high samples confined in the brass rings are permitted to air dry at 105° F for at least 48 hours prior to placing into the expansion apparatus. A unit load of 500 pounds per square foot is then applied to the upper porous stone in contact with the top of each sample. Water is permitted to contact both the top and bottom of each sample through porous stones. Continuous observations are made until downward movement stops. The dial reading is recorded and expansion is recorded until the rate of upward movement is less than 1/10000 inch per hour. BENTON ENGINEERING, INC.
