At that time, Terracon was onsite to observeand test the placement of engineered fill material.Cut and fill slopes No steeper than 3H:IV (Horizontal to Vertical) (assumed)2.2 Site Location and DescriptioniITEM DESCRIPTIONThe proposed project site consists of Lots 2, 5, 6, 7 8, 9, 10, 11, 12,Location 13, 14, 15, 16, 17 and 18 of Discovery Ridge Research Park inColumbia, Missouri.The lots are vacant with the exception. of Lot 5 which is developedExisingimprvemntswith a storage building.Generally grass covered, however portions of the site in the vicinityCurret grund overof Lot 16 were cultivated fields.In general, slightly to moderately sloped downward towards theExisting topography south and west.3.0 SUBSURFACE CONDITIONS3.1 GeologyMost of the upland area is covered by a thin loess blanket and glacial drift. Highly plastic claysthat exhibit volume change with variations in moisture are commonly encountered near theground surface.Based on the 2003 Geologic Map of Missouri, Missouri Department of Natural Resources,bedrock at this site consists primarily of the Pennsylvanian aged Cherokee Group (Pc), thePennsylvanian aged Marmaton Group (Pmo), and the Mississippian aged Burlington formation(Mo). The Cherokee Group is predominantly shale with minor amounts of carbonates andsandstone. This group contains most of the mineable coal beds in Missouri. The MarmatonGroup consists of a succession of shale, limestone, clay, and coal beds.Reliable

Solution features,including caves and sinkholes, are commonly present in this formation. No caves or sinkholesare known to exist, or are published to exist, within approximately 1 mile of this project site.However several areas of known karst activity are present west and southwest of the projectsite.It is difficult to predict future sinkhole activity. Sinkholes and caves in this area are in variousstages of development and can appear at any time. Site grading and drainage may alter siteconditions and could possibly cause sinkholes in areas that have no history of this activity.3.2 Typical ProfileBased on the results of the borings, subsurface conditions on the project site can be generalizedas follows:Stratum Approximate Depth to Maera D1citinConsistency/DensityBottom of Stratum (feet) Mtra ecitoSurface 0.2 to 0.5 Topsoil: brown, friable and contained N/Asignificant organic mailer3 to 12 Existing Fill 1 consisting of lean clayI and lean to fat clay with Very stiff to hard(Borings B-3 &B-4 only) varying amounts of sand and gravel ___________2 3 to 12 Lean clay, lean to fat clay and fat clay Stiff to very stiffUndeermned BorngsB-I Lean to fat clay and fat clay withthrough B-5, B-8 and B-9 vainamutofsdgvead3 terinatd witin tis statum possible cobbles (visually classified asStftohrat the planned depth of gailditapproximately 20 feetUndetermined: Borings B-6 Caused split spoon4 and B-7 terminated within Limestone sampler refusal andthis stratum. auger refusalNote 1: The existing fill material was placed in mid to late 2008.

Details for each of theborings can be found on the boring logs in Appendix A of this report.3.3 GroundwaterThe boreholes were observed while drilling and after completion for the presence and level ofgroundwater. Groundwater was observed at in Borings B-5 and B-6 at depths of approximately12 to 18.5 feet. Groundwater was not observed in the remaining borings during drilling or for theshort amount of time the borings were allowed to remain open following drilling completion.However, this does not necessarily mean that stable groundwater levels were observed in BoringsB-5 and B-6, or that the remaining borings were terminated above groundwater.Due to the low permeability of the soils encountered in the borings, a relatively long period of timemay be necessary for a groundwater level to develop and stabilize in a borehole in these materials.Long term observations in piezometers or observation wells sealed from the influence of surfacewater are often required to define groundwater levels in materials of this type.Pockets, lenses, and stringers of sand are sometimes encountered in the glacial soils found inthe vicinity of the referenced project. These sand pockets are normally discontinuous and oftencontain water of variable quality and quantity. These sand pockets may be encountered duringfoundation excavation. This possibility should be considered when developing design andconstruction plans and specifications for the project.Groundwater level fluctuations occur due to seasonal variations in the amount of rainfall, runoff,proximity to existing ponds, and other factors not evident at the time the borings wereperformed. In addition, perched water can develop over low permeability soil strata. Therefore,groundwater levels during construction or at other times in the life of the structure may be higheror lower than the levels indicated on the boring logs. The possibility of groundwater levelfluctuations should be considered when developing the design and construction plans for theproject.Reliable

Existing fill was encountered in Borings B-3 and B-4 to depths of 3 to 12feet, and limestone bedrock was encountered in Borings B-6 and B-7 at depths of approximately17 and 12.5 feet, respectively. Depending on final site grading plans, we anticipate that either thenative clay or compacted structural fill will form the subgrade for future building foundations andfloor slabs.Based on the USGS map, it appears that a pond may have been located in the vicinity of lot 16.Further, based on aerial photography the existing pond located north of the Radii Facility previouslyextended southwest onto a portion of Lot 2. We recommend these areas be thoroughlyinvestigated during the final geotechnical investigation for each respective lot.Performance of foundations depends on many factors including, but not limited to, the depth offootings, amounts of cuts or fill, bearing material, and foundation loads. Structural loads, finalgrades, and other design' details should be provided when available. Although this reportdiscusses design parameters, these parameters are preliminary. This preliminary report is notintended to be relied upon for final design. We recommend a more detailed study be performedwhen specific project details are known, and/or possibly following completion of general sitegrading.Examination of the boring logs indicates a range of soil-moisture conditions are present at thissite. At the time of drilling, some of the soils at various depths are at moisture levels above theirmeasured plastic limit. Typically, soil with moisture levels above their measured plastic limit maybe prone to rutting, pumping, and can develop into unstable subgrade conditions during generalconstruction operations.Moderately to highly plastic, lean to fat clay and fat clay soils were present on site. Such soils arecommonly referred to as "expansive"~ or "swelling" soils because they expand or swell as theirmoisture contents increase. However, these soils also "contract" or "shrink" as their moisturelevels decrease. Footings, floor slabs, and pavements supported on expansive soils will moveupward and downward and such movements will result in distortion, possibly causing cracking orstructural damage to structures. For this reason, a low volume change zone will likely berequired beneath at-grade floor slabs. We recommend that additional laboratory testing beperformed during the final geotechnical exploration to better evaluate the expansive nature ofthese soils.Reliable u Responsive

  • Terracon Project No. 09105094.1.1We recommend that the exposed subgrade be thoroughly evaluated after stripping of anytopsoil and creation of all cut areas, but prior to the start of any fill operations. We recommendthat the geotechnical engineer be retained to evaluate the bearing material for the foundationsand floor slab subgrade soils. Subsurface conditions, as identified by the field and laboratorytesting programs, have been reviewed and evaluated with respect to the proposed developmentplans known to us at this time.4.2 EarthworkThe widely spaced preliminary borings typically encountered stiff to hard lean to fat clay and fatclay. Shallow bedrock, karst features, or extensive pervious deposits of water-bearing sand thatcould impact site development did not appear to be present based on the preliminary site andsubsurface information gathered at this time.Based on the subsurface conditions encountered in the widely spaced borings, the site soils aresuitable for future development. Additional borings should be completed so that each site can beadequately characterized and recommendations can be more fully developed to assist and guidefuture mass grading.Recommendations will need to be developed for site preparation and proof-rolling operations aswell as construction of cut and structural fill operations. In our opinion, full-time testing andobservation should be employed during mass grading to evaluate compliance with projectearthwork recommendations and requirements. If site grading results in relatively thick structuralfills, settlement and cut/fill slope stability may need to be evaluated.4.3 FoundationsShallow foundations could be used to support lightly loaded commercial structures provided thefootings are supported by suitable material (stiff to hard native clay or compacted structural fill).Depending on the design footing elevation and bearing material (native clay or newly placedcompacted structural fill), allowable bearing pressures would likely be in the range of 1,000 psf to3,000 psf. Due to the presence of clay soils, shallow foundations are typically soil-formed in thegeneral vicinity of this site. Further testing at the individual structure locations should beperformed to determine the appropriate bearing capacity for structural support.Heavier loads, which could cause excessive settlement, are normally supported by shallowfoundations which are supported, in turn, by aggregate-pier intermediate foundations or by drilledpiers. Pier drilling through the native soils is not expected to become difficult based upon thematerial encountered within the borings; however, the drilled pier contractor should be preparedshould sandy zones or large boulders be encountered.

See Appendix C, Exhibit C-4 for Projected Earthquake Intensities (Modified Mercalli Scale)Code Used Site Classification2006/2009 International Building Code (IBC) C1.2.In general accordance with the 2006/2009 International Building Code, Table 1613.5.2.The 2006/2009 International Building Code requires a site soil profile determination extending adepth of 100 feet for seismic site classification. The current scope requested does not include therequired 100 foot soil profile determination. Borings for this report extended to a maximum depth ofapproximately 20 feet and this seismic site class assignment considers that shale or limestonebedrock is present within approximately 30 feet of the ground surface and continues below themaximum depth of the subsurface exploration. Additional exploration to greater depths could beconsidered to confirm the conditions below the current depth of exploration. Alternatively, ageophysical exploration could be utilized in order to attempt to justify a more favorable seismic siteclass.Reliable

  • Columbia, MissouriFebruary 17, 2011 u Terracon Project No. 09105094.1.14.5 Floor SlabsMany of the clay soils in this locale have the potential to increase or decrease in volume withvariations in moisture content. Soil having high plasticity characteristics (i.e., fat clay) generallyhas a greater potential for moisture related volume change than less plastic materials such aslean clay. In addition, swell potential is generally greater in material with a high dry unit weightand low initial moisture content. However, even low plasticity soils can swell significantly if theirmoisture levels are initially low.Because of the moderate to high shrink-swell potential of the lean to fat clay and fat clay soilencountered in the borings, a low volume change layer will likely be required below at-gradefloor slabs. This layer typically varies from 12 to 36 inches in thickness. The on-site lean to fatclay and fat clay soils encountered in the borings performed for this report are typically notsuitable for use as low volume change material; however, on-site materials may exist whichwould meet the low volume change material criteria. Further testing at the individual structurelocations should be performed to determine the required low volume change layer thickness.4.6 PavementsOn most project sites, the site grading is accomplished relatively early in the construction phase.Fills are placed and compacted in a uniform manner. However, as construction proceeds,excavations are made into these areas, rainfall and surface water saturates some areas, heavytraffic from concrete trucks and other delivery vehicles disturbs the subgrade and many surfaceirregularities are filled in with loose soils to improve trafficability temporarily. As a result, thepavement subgrades, initially prepared early in the project, should be carefully evaluated as thetime for pavement construction approaches.Pavement thickness can be determined using AASHTO, Asphalt Institute and/or other methods ifspecific wheel loads, axle configurations, frequencies, and desired pavement life are provided.Pavement design methods are intended to provide structural sections with adequate thicknessover a particular subgrade such that wheel loads are reduced to a level the subgrade can support.The support characteristics of the subgrade for pavement design do not account for shrink/swellmovements of an expansive clay subgrade such as the soils encountered on this project. Thus,the pavement may be adequate from a structural standpoint, yet still experience cracking anddeformation due to shrink/swell related movement of the subgrade.Expansive soils are present at this site. It is important to minimize moisture changes in thesubgrade both during construction and during the life of the pavement to reduce shrink/swellmovements.Reliable.* Responsive u Convenient m Innovative88 Preliminary Geotechnical Engineering Report 1rDiscovery Ridge -Certified Site Program ra aLots 2, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 and 18

The ground surfaceelevations at the boring locations were interpolated from a topographic map provided by theclient. The elevations included on the boring logs are approximate and have been rounded tothe nearest 5-foot. The locations and elevations of the borings should be considered accurateonly to the degree implied by the means and methods used to define them.The borings were drilled with an ATV-mounted rotary drill rig using continuous flight solid-stemaugers to advance the boreholes. Samples of the soil encountered in the borings were obtainedusing the split-barrel and thin-walled tube sampling procedures.In the split-barrel sampling procedure, the number of blows required to advance a standard 2-inch O.D. split-barrel sampler the last 12 inches of the typical total 18-inch penetration by meansof a 140-pound hammer with a free fall of 30 inches, is the standard penetration resistancevalue (SPT-N). This value is used to estimate the in-situ relative density of cohesionless soilsand consistency of cohesive soils.A CME automatic SPT hammer was used to advance the split-barrel sampler in the boringsperformed on this site. A significantly greater efficiency is achieved with the automatic hammercompared to the conventional safety hammer operated with a cathead and rope. This higherefficiency has an appreciable effect on the SPT-N value. The effect of the automatic hammer'sefficiency has been considered in the interpretation and analysis of the subsurface informationfor this report.In the thin-walled tube sampling procedure, a thin-walled, seamless steel tube with a sharp cuttingedge is pushed hydraulically in to the soil to obtain a relatively undisturbed sample. The sampleswere tagged for identification, sealed to reduce moisture loss, and taken to our laboratory forfurther examination, testing, and classification. Information provided on the boring logs attached tothis report includes soil descriptions, consistency evaluations, boring depths, sampling intervals,and groundwater conditions. The borings were backfilled with auger cuttings prior to the drill crewleaving the site.A field log of each boring was prepared by the drill crew. These logs included visual classificationsof the materials encountered during drilling as well as the driller's interpretation of the subsurfaceconditions between samples. Final boring logs included with this report represent the engineer'sinterpretation of the field logs and include modifications based on laboratory observation and testsof the samples.Reliable a Responsive a Convenient

Unconfined compression tests were performed on selected samples and a calibratedhand penetrometer was used to estimate the approximate unconfined compressive strength ofsome samples. The calibrated hand penetrometer has been correlated with unconfinedcompression tests and provides a better estimate of soil consistency than visual examinationalone. The test results are provided on the boring logs included in Appendix A.Descriptive classifications of the soils indicated on the boring logs are in accordance with theenclosed General Notes and the Unified Soil Classification System. Also shown are estimatedUnified Soil Classification Symbols. A brief description of this classification system is attachedto this report. All classification was by visual manual procedures.

Groundwater levels at othertimes and other locations across the site could vary. In pervious soils, the indicated levels may reflect the location of groundwater. In lowpermeability soils, the accurate determination of groundwater levels may not be possible with only short-term observations.DESCRIPTIVE SOIL CLASSIFICATION: Soil classification is based on the Unified Soil Classification System. Coarse Grained Soilshave more than 50% of their dry weight retained on a #200 sieve; their principal descriptors are: boulders, cobbles, gravel or sand. FineGrained Soils have less than 50% of their dry weight retained on a #200 sieve; they are principally described as dlays if they are plastic,and silts if they are slightly plastic or non-plastic. Major constituents may be added as modifiers and minor constituents may be addedaccording to the relative proportions based on grain size. In addition to gradation, coarse-grained soils are defined on the basis of theirin-place relative density and fine-grained soils on the basis of their consistency.CONSISTENCY OF FINE-GRAINED SOILSRELATIVE DENSITY OF COARSE-GRAINED SOILSUnconfinedCompressiveStrength.

Highly plastic claysthat exhibit volume change with variations in moisture are commonly encountered near theground surface.Based on the 2003 Geologic Map of Missouri, Missouri Department of Natural Resources,bedrock at this site consists primarily of the Pennsylvanian aged Cherokee Group (Pc), thePennsylvanian aged Marmaton Group (Pmo), and the Mississippian aged Burlington formation(Mo). The Cherokee Group is predominantly shale with minor amounts of carbonates andsandstone. This group contains most of the mineable coal beds in Missouri. The MarmatonGroup consists of a succession of shale, limestone, clay, and coal beds.Reliable

Solution features,including caves and sinkholes, are commonly present in this formation. No caves or sinkholesare known to exist, or are published to exist, within approximately 1 mile of this project site.However several areas of known karst activity are present west and southwest of the projectsite.It is difficult to predict future sinkhole activity. Sinkholes and caves in this area are in variousstages of development and can appear at any time. Site grading and drainage may alter siteconditions and could possibly cause sinkholes in areas that have no history of this activity.3.2 Typical ProfileBased on the results of the borings, subsurface conditions on the project site can be generalizedas follows:Stratum Approximate Depth to Maera D1citinConsistency/DensityBottom of Stratum (feet) Mtra ecitoSurface 0.2 to 0.5 Topsoil: brown, friable and contained N/Asignificant organic mailer3 to 12 Existing Fill 1 consisting of lean clayI and lean to fat clay with Very stiff to hard(Borings B-3 &B-4 only) varying amounts of sand and gravel ___________2 3 to 12 Lean clay, lean to fat clay and fat clay Stiff to very stiffUndeermned BorngsB-I Lean to fat clay and fat clay withthrough B-5, B-8 and B-9 vainamutofsdgvead3 terinatd witin tis statum possible cobbles (visually classified asStftohrat the planned depth of gailditapproximately 20 feetUndetermined: Borings B-6 Caused split spoon4 and B-7 terminated within Limestone sampler refusal andthis stratum. auger refusalNote 1: The existing fill material was placed in mid to late 2008.

Details for each of theborings can be found on the boring logs in Appendix A of this report.3.3 GroundwaterThe boreholes were observed while drilling and after completion for the presence and level ofgroundwater. Groundwater was observed at in Borings B-5 and B-6 at depths of approximately12 to 18.5 feet. Groundwater was not observed in the remaining borings during drilling or for theshort amount of time the borings were allowed to remain open following drilling completion.However, this does not necessarily mean that stable groundwater levels were observed in BoringsB-5 and B-6, or that the remaining borings were terminated above groundwater.Due to the low permeability of the soils encountered in the borings, a relatively long period of timemay be necessary for a groundwater level to develop and stabilize in a borehole in these materials.Long term observations in piezometers or observation wells sealed from the influence of surfacewater are often required to define groundwater levels in materials of this type.Pockets, lenses, and stringers of sand are sometimes encountered in the glacial soils found inthe vicinity of the referenced project. These sand pockets are normally discontinuous and oftencontain water of variable quality and quantity. These sand pockets may be encountered duringfoundation excavation. This possibility should be considered when developing design andconstruction plans and specifications for the project.Groundwater level fluctuations occur due to seasonal variations in the amount of rainfall, runoff,proximity to existing ponds, and other factors not evident at the time the borings wereperformed. In addition, perched water can develop over low permeability soil strata. Therefore,groundwater levels during construction or at other times in the life of the structure may be higheror lower than the levels indicated on the boring logs. The possibility of groundwater levelfluctuations should be considered when developing the design and construction plans for theproject.Reliable

Existing fill was encountered in Borings B-3 and B-4 to depths of 3 to 12feet, and limestone bedrock was encountered in Borings B-6 and B-7 at depths of approximately17 and 12.5 feet, respectively. Depending on final site grading plans, we anticipate that either thenative clay or compacted structural fill will form the subgrade for future building foundations andfloor slabs.Based on the USGS map, it appears that a pond may have been located in the vicinity of lot 16.Further, based on aerial photography the existing pond located north of the Radii Facility previouslyextended southwest onto a portion of Lot 2. We recommend these areas be thoroughlyinvestigated during the final geotechnical investigation for each respective lot.Performance of foundations depends on many factors including, but not limited to, the depth offootings, amounts of cuts or fill, bearing material, and foundation loads. Structural loads, finalgrades, and other design' details should be provided when available. Although this reportdiscusses design parameters, these parameters are preliminary. This preliminary report is notintended to be relied upon for final design. We recommend a more detailed study be performedwhen specific project details are known, and/or possibly following completion of general sitegrading.Examination of the boring logs indicates a range of soil-moisture conditions are present at thissite. At the time of drilling, some of the soils at various depths are at moisture levels above theirmeasured plastic limit. Typically, soil with moisture levels above their measured plastic limit maybe prone to rutting, pumping, and can develop into unstable subgrade conditions during generalconstruction operations.Moderately to highly plastic, lean to fat clay and fat clay soils were present on site. Such soils arecommonly referred to as "expansive"~ or "swelling" soils because they expand or swell as theirmoisture contents increase. However, these soils also "contract" or "shrink" as their moisturelevels decrease. Footings, floor slabs, and pavements supported on expansive soils will moveupward and downward and such movements will result in distortion, possibly causing cracking orstructural damage to structures. For this reason, a low volume change zone will likely berequired beneath at-grade floor slabs. We recommend that additional laboratory testing beperformed during the final geotechnical exploration to better evaluate the expansive nature ofthese soils.Reliable u Responsive

  • Terracon Project No. 09105094.1.1We recommend that the exposed subgrade be thoroughly evaluated after stripping of anytopsoil and creation of all cut areas, but prior to the start of any fill operations. We recommendthat the geotechnical engineer be retained to evaluate the bearing material for the foundationsand floor slab subgrade soils. Subsurface conditions, as identified by the field and laboratorytesting programs, have been reviewed and evaluated with respect to the proposed developmentplans known to us at this time.4.2 EarthworkThe widely spaced preliminary borings typically encountered stiff to hard lean to fat clay and fatclay. Shallow bedrock, karst features, or extensive pervious deposits of water-bearing sand thatcould impact site development did not appear to be present based on the preliminary site andsubsurface information gathered at this time.Based on the subsurface conditions encountered in the widely spaced borings, the site soils aresuitable for future development. Additional borings should be completed so that each site can beadequately characterized and recommendations can be more fully developed to assist and guidefuture mass grading.Recommendations will need to be developed for site preparation and proof-rolling operations aswell as construction of cut and structural fill operations. In our opinion, full-time testing andobservation should be employed during mass grading to evaluate compliance with projectearthwork recommendations and requirements. If site grading results in relatively thick structuralfills, settlement and cut/fill slope stability may need to be evaluated.4.3 FoundationsShallow foundations could be used to support lightly loaded commercial structures provided thefootings are supported by suitable material (stiff to hard native clay or compacted structural fill).Depending on the design footing elevation and bearing material (native clay or newly placedcompacted structural fill), allowable bearing pressures would likely be in the range of 1,000 psf to3,000 psf. Due to the presence of clay soils, shallow foundations are typically soil-formed in thegeneral vicinity of this site. Further testing at the individual structure locations should beperformed to determine the appropriate bearing capacity for structural support.Heavier loads, which could cause excessive settlement, are normally supported by shallowfoundations which are supported, in turn, by aggregate-pier intermediate foundations or by drilledpiers. Pier drilling through the native soils is not expected to become difficult based upon thematerial encountered within the borings; however, the drilled pier contractor should be preparedshould sandy zones or large boulders be encountered.

The current scope requested does not include therequired 100 foot soil profile determination. Borings for this report extended to a maximum depth ofapproximately 20 feet and this seismic site class assignment considers that shale or limestonebedrock is present within approximately 30 feet of the ground surface and continues below themaximum depth of the subsurface exploration. Additional exploration to greater depths could beconsidered to confirm the conditions below the current depth of exploration.

  • Columbia, MissouriFebruary 17, 2011 u Terracon Project No. 09105094.1.14.5 Floor SlabsMany of the clay soils in this locale have the potential to increase or decrease in volume withvariations in moisture content. Soil having high plasticity characteristics (i.e., fat clay) generallyhas a greater potential for moisture related volume change than less plastic materials such aslean clay. In addition, swell potential is generally greater in material with a high dry unit weightand low initial moisture content. However, even low plasticity soils can swell significantly if theirmoisture levels are initially low.Because of the moderate to high shrink-swell potential of the lean to fat clay and fat clay soilencountered in the borings, a low volume change layer will likely be required below at-gradefloor slabs. This layer typically varies from 12 to 36 inches in thickness. The on-site lean to fatclay and fat clay soils encountered in the borings performed for this report are typically notsuitable for use as low volume change material; however, on-site materials may exist whichwould meet the low volume change material criteria. Further testing at the individual structurelocations should be performed to determine the required low volume change layer thickness.4.6 PavementsOn most project sites, the site grading is accomplished relatively early in the construction phase.Fills are placed and compacted in a uniform manner. However, as construction proceeds,excavations are made into these areas, rainfall and surface water saturates some areas, heavytraffic from concrete trucks and other delivery vehicles disturbs the subgrade and many surfaceirregularities are filled in with loose soils to improve trafficability temporarily. As a result, thepavement subgrades, initially prepared early in the project, should be carefully evaluated as thetime for pavement construction approaches.Pavement thickness can be determined using AASHTO, Asphalt Institute and/or other methods ifspecific wheel loads, axle configurations, frequencies, and desired pavement life are provided.Pavement design methods are intended to provide structural sections with adequate thicknessover a particular subgrade such that wheel loads are reduced to a level the subgrade can support.The support characteristics of the subgrade for pavement design do not account for shrink/swellmovements of an expansive clay subgrade such as the soils encountered on this project. Thus,the pavement may be adequate from a structural standpoint, yet still experience cracking anddeformation due to shrink/swell related movement of the subgrade.Expansive soils are present at this site. It is important to minimize moisture changes in thesubgrade both during construction and during the life of the pavement to reduce shrink/swellmovements.Reliable.* Responsive u Convenient m Innovative88 Preliminary Geotechnical Engineering Report 1rDiscovery Ridge -Certified Site Program ra aLots 2, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 and 18

The ground surfaceelevations at the boring locations were interpolated from a topographic map provided by theclient. The elevations included on the boring logs are approximate and have been rounded tothe nearest 5-foot. The locations and elevations of the borings should be considered accurateonly to the degree implied by the means and methods used to define them.The borings were drilled with an ATV-mounted rotary drill rig using continuous flight solid-stemaugers to advance the boreholes. Samples of the soil encountered in the borings were obtainedusing the split-barrel and thin-walled tube sampling procedures.In the split-barrel sampling procedure, the number of blows required to advance a standard 2-inch O.D. split-barrel sampler the last 12 inches of the typical total 18-inch penetration by meansof a 140-pound hammer with a free fall of 30 inches, is the standard penetration resistancevalue (SPT-N). This value is used to estimate the in-situ relative density of cohesionless soilsand consistency of cohesive soils.A CME automatic SPT hammer was used to advance the split-barrel sampler in the boringsperformed on this site. A significantly greater efficiency is achieved with the automatic hammercompared to the conventional safety hammer operated with a cathead and rope. This higherefficiency has an appreciable effect on the SPT-N value. The effect of the automatic hammer'sefficiency has been considered in the interpretation and analysis of the subsurface informationfor this report.In the thin-walled tube sampling procedure, a thin-walled, seamless steel tube with a sharp cuttingedge is pushed hydraulically in to the soil to obtain a relatively undisturbed sample. The sampleswere tagged for identification, sealed to reduce moisture loss, and taken to our laboratory forfurther examination, testing, and classification. Information provided on the boring logs attached tothis report includes soil descriptions, consistency evaluations, boring depths, sampling intervals,and groundwater conditions. The borings were backfilled with auger cuttings prior to the drill crewleaving the site.A field log of each boring was prepared by the drill crew. These logs included visual classificationsof the materials encountered during drilling as well as the driller's interpretation of the subsurfaceconditions between samples. Final boring logs included with this report represent the engineer'sinterpretation of the field logs and include modifications based on laboratory observation and testsof the samples.Reliable a Responsive a Convenient

Coarse Grained Soilshave more than 50% of their dry weight retained on a #200 sieve; their principal descriptors are: boulders, cobbles, gravel or sand. FineGrained Soils have less than 50% of their dry weight retained on a #200 sieve; they are principally described as dlays if they are plastic,and silts if they are slightly plastic or non-plastic. Major constituents may be added as modifiers and minor constituents may be addedaccording to the relative proportions based on grain size. In addition to gradation, coarse-grained soils are defined on the basis of theirin-place relative density and fine-grained soils on the basis of their consistency.CONSISTENCY OF FINE-GRAINED SOILSRELATIVE DENSITY OF COARSE-GRAINED SOILSUnconfinedCompressiveStrength.
