Based upon our past experience with McDonald's facilities, we expect the new construction to'be a single -story structure with a masonry veneer exterior.and concrete slab -on -grade floor system. Maximum column and wall loads -.of 50 kips and 3 kips -per linear foot, respectively, are also anticipated. In general, the borings initially penetrated a relatively thin surficia[ layer of topsoil. The topsoil was about 1 to 2 inches thick and consists of brown silty sand with fine roots and organic matter. The,topsoil thickness will differ at other locations. The natural site soils are Coastal Plain sediments of sand and clay extending to the 10 and 15- foot depths explored. The upper sediments typically consist of poorly graded sand (SP), silty sand (SM), and clayey sand (SC) extending to depths of about ,6 to 13 feet below the ground surface. The SPT N-va[ues for the sand, layers ranged from 8 to 53 knows per foot (bpf) denoting loose to very dense relative densities. The upper sediments are underlain by -layers of sandy day (CL) and clayey sand (SC) extending to the 15-foot depth explored. The SPT N- values for the clay, layers encountered ranged from 21 to 27 bpf denoting very stiff consistencies. The SPT N-values for the sand layers encountered ranged from 14 to 24 bpf denoting medium dense relative densities. Groundwater was not observed in the borings at the completion of drilling operations. Boring cave-in depths ranged from about 5 to 10 feet below the existing site grades. In summary, our findings indicate that the structure -can be supported on conventional shallow foundations bearing on approved natural soils and/or new engineered fill. Provided the proposed 'foundations are constructed in strict accordance with the recommendations provided herein,'the shallow foundations can be proportioned for a net allowable design bearing pressure of 2,500 pounds per square foot (psf). Concrete slabs -on -grade supported by approved in - place soils or properly prepared engineered fills can be designed using a modulus of subgrade reaction of 125 pounds per cubic inch (pci). Based on Section 1613 of the 2012 North Carolina State Building Code, and the ReMi Survey performed at the site, a Seismic Site Class "C" may be used for design. Based on the subsurface conditions encountered in the soil test borings and expected ground motions. at the site, the potential for liquefaction at the site is considered low. The site soils will rapidly deteriorate when subject to construction traffic, particularly following periods of wet weather. Subgrades that become unstable or otherwise degrade will need to be undercut and replaced with satisfactory fill materials. The volume of undercut materla[.will be a function of the time of the year -in which the grading occurs. 'Greater undercutting should be expected if grading. occurs during the wet winter and spring months. Mc Don aId's Restaurant #32-1598 Spring Lake, North Carolina ECS Project No, 33:2002-A Page 2 Our General foundation, slab, and pavement recommendations are summarized in the following table: Bearing Capacity: 2:500 psf for approved natural soils or new engineered fill Foundations. Shallow footings — minimum 18 inches for continuous, while isolated column footings should have a: minimum lateral dimension of 24 inches,,18 inches.minimum,.embedment F[oor,Slab: Ground supported, wire -mesh reinforced minimum or fiber reinforced Pavement: Asphalt Light Duty: 3.0" Asphalt Surface Course on 6" ABC stone Medium Du -. 3.0" Asphalt Surface Course. on 8" ABC stone Pavement: Concrete 6 inches Port[and cement concrete (4;000 psi compressive strength at 28 days) over not less than 6 inches of compacted aggregate base course Specific information regarding the subsurface exploration procedures used, the site and subsurface conditions at the time of our- exploration, and our conclusions and recommendations concerning the geotechnical design and construction aspects of the project are discussed in detail in the subsequent sections of this report. Please note this Executive .Summary is an important part of this report but should be considered a `summary" only and should not be relied upon exclusive of the entire report. The subsequent sections of this report constitute our findings, conclusions, and recommendations in their entirety, McDonald's Res taurant #n-1 588 Spring l.aka, North Carolina ECS Project No. 33:2002-A Page 3 2.0 PROJECT INFORMATION Our understanding of the proposed construction is based upon our past experience with other McDonald's, projects, the soil testing requirements. for the project and a site plan furnished by McDonald's Corporation. It is our understanding that. a new McDonald's restaurant will be. constructed at the Anderson Creek Shopping Plaza located at the intersection_ of Old Farm Road (Ray Road) and Overhills Road in Spring Lake, North Carolina as shown on Figure 1 in the Appendix. Based upon our past experience with similar facilities, we expect the new, construction to be a single -story structure with a masonry veneer exterior and concrete slab -on - grade floor system. Maximum column and wall loads of 50kips and 3 kips per linear foot, respectively, are also anticipated. Additional site construction is expected to include paved parking and drive areas, underground utilities, and landscaping. Site topographic information had not been provided to ECS .at the time. of this report. Based upon the relatively uniform existing ground surface elevations, we anticipate that earth cuts and fills on the order of 2 feet or less may be required to established finished subgrade elevations in planned building and pavement areas. McDonald's Rostaurant #32-1588 Spring Lake, North Carolina EC9 Project No. 33:2002-A Page 4 3.0 EXPLORATION PROCEDURES 3.1 Field Exploration 3.1.1 Soil Test Borinas Eleven soil lest borings (B-1 through 13-11) • were performed during our field exploration. Borings 13-1 through B-5 were completed in the proposed building area and borings B-6 through B-11 were completed in the proposed pavement areas. The borings located in the building area were advanced to depths of 15 feet below existing site. grades. The borings located in the proposed pavement areas were advanced to depths of about 10 feet below the existing, ground surface. One bulk sample of the soils anticipated to be used as pavement subgrade were obtained for laboratory testing. The soil test borings. were located in the field by ECS personnel by estimating distances and angles from existing site. features. The boring locations are shown on the Boring Location Diagram in the Appendix of this report, and should be considered approximate given' the location method used. The,soil borings were performed with a CME 75-truck mounted drilling rig, which utilized hollow - stern augers to advance the boreholes. Representative soil samples were obtained by means of the split -barrel sampling procedure in general accordance with ASTM Specification D-1586. In this procedure, a'2-inch 0. D. split -barrel sampler is driven into the soil a distance of 18 inches by a 140 pound hammer with a free fall -of 30 inches. The number of blows required to drive the sampler through the final 12 inch interval is termed the Standard Penetration Test (SPT) N-value and is indicated for each sample on the boring logs. "The SPT N-value can be used to provide a qualitative indication of the in -place relative density of cohesionless soils. In a less reliable way, SPT N-values provide an indication of consistency for cohesive soils. These indications of relative density and consistency are qualitative, since many factors can significantly affect the SPT N-value and prevent a direct correlation between drill crews, drill rigs, drilling procedures, and hammer -rod -sampler assemblies. Field logs of the soils encountered in the borings were maintained by the drill crew. The soil samples obtained from the drilling operations were sealed in glass jars and brought to. our Fayetteville, North Carolina laboratory for further examination and testing. 11.2 Refraction Microtremor A Refraction Microtremor (ReMi)' survey was performed at the site at the approximate location shown on Figure 2, in the -Appendix of the report. The data was processed using SelsOpt4 ReMi'"" software to reveal a two-dimensional average shear -wave (S-wave) velocity image for the line (array). fn addition, the survey also provides the average shear wave velocity to a depth of up to 10b feet which was used to determine the seismic Site. Class. The data gathering process in the field used standard seismic refraction equipment to measure site characteristics using ambient vibrations (microtremors)' as a seismic source. The equipment used for the- survey included a GEODE ReMi recording unit capable of storing record lengths up to about 100 seconds and 18, 10-Hz vertical P-wave geophones. The analysis presented here was developed from the 18 receivers (10 Hz geophones) set along a McDonald's Restaurant 432.1588 Spring Lake, North Carolina ECS Project No. 33:2002-A Page 5 relatively straight-line 'array with evenly spaced intervals (15 feet) between the receivers. Twelve unfiltered 30-second records were recorded along the line. The vibration records collected above were processed using proprietary software and the refraction microtremor method as explained in Louie, J, N, 2001, "Faster, Better: Shear -wave velocity to 100 meters depth from'. refraction micrometer arrays", Bulletin of the Seismblogical Society of America, v. 91, p.347-364. For each location.(array), there are three main processing steps: Step 1: Creating a velocity spectrum (p-f image) from the data: The distinctive slope of dispersive waves is an integral part of the p-f analysis. Other arrivals that appear in microtremor records, such as body waves and airwaves, cannot have such a slope. Step 2: Rayleigh -wave dispersion picking: Picking is done along a "lowestwelocity envelope" bounding the energy appearing in the p-f image. Step 3: Shear wave velocity modeling: The refraction microtremor method interactively forward - models the normal -mode dispersion data picked from p-f images. The weighted averages of the. shear wave velocities for the array, according to the 2012 North Carolina State Building Code (NCSBC), is presented in Figure 3 in the Appendix of this report. The seismic, site class definitions for the weighted average of shear wave velocity in the upper 100 feet -of the.soil profile are presented in Table 1613.5.2 of the 2012 NCSBC. 3.2 Laboratory Testing Program Representative, soil samples obtained during our held exploration were selected and tested in our laboratory to verify field classifications and to aid in determining engineering properties of the on -site soils. Laboratory testing included visual classifications in general accordance with the Unified Soil Classification System (USCS as described in ASTM D 2487), moisture content testing (ASTM D 2216), Atterberg limits testing (ASTM D 4318), percent of particles finer than the U.S. standard sieve No, 200 sieve testing (ASTM D, 1140), modified Proctor compaction testing (ASTM D 1557), and California Searing Ratio testing (ASTM D 1883). The laboratory testing was performed in general conformance with the referenced ASTM standards. The Laboratory Testing Summary, in the Appendix of this report presents all of the test results. McDonald's Restaurant 432-1588 Spring Lake, North Carolina EC5 Project No. 33:2002•A Page B 4.0 SITE AND SUBSURFACE CONDITIONS 4.1 Site Observations The project site is an approximately 1':56 acre parcel in the Anderson Creek Shopping Plaza located at the intersection of Old Farm Road (Ray Road) and Overhills Road in Spring Lake, North Carolina. The site is bounded by Overhills Road to the north and west, Old Farm Road (Ray Road) to the south, and the asphalt paved :parking lot of the shopping plaza to the east. An asphalt paved access road for the shopping plaza extends across the site from Overhills Road on the north to the shopping plaza parking lot on the east. Ground cover in the remaining portions of the, site consists of grass. The site is relatively flat with an estimated elevation differential of'about 2 to 3 feet across the proposed building and pavement areas. The current site grades are generally consistent with the surrounding topography. 4.2 Area Geoloav The referenced site is located within the Coastal Plain. Province of North Carolina. The Coastal Plain Province is a broad flat plain with widely spaced low rolling hills where the near surface soils have their origin from the, deposition of sediments several million years ago during the period that the ocean receded from this area to its present location along the Atlantic Coast. It is noted that the Coastal Plain, soils vary in thickness from only,a few feet along the western border to over ten thousand feet in some areas along the coast. The sedimentary deposits of -the Coastal Plain rest upon consolidated rocks similar to those underlying the Piedmont and Mouritain Physiographic Provinces. In general, shallow 'unconfined groundwater movement within the overlying soils is largely controlled by topographic gradients. Recharge occurs primarily by infiltration along higher elevations and typically discharges into streams or other surface water bodies. The elevation of the shallow water table is transient and can vary greatly -with seasonal fluctuations in precipitation. 4.3 Subsurface Conditions In general, the borings initially penetrated a relatively thin surficial layer of topsoil. The topsoil was about 1 to 2 inches thick and consists of brown silty sand with fine roots and organic matter. The topsoil thickness will differ at locations intermediate of the borings. The natural site soils are Coastal Plain sediments of sand and clay extending to the 10 and 15- foot depths explored. The upper sediments typically consist of poorly graded sand (SP), silty sand (SM), and clayey sand (SC) extending to depths of about 6 to 13 feet below the ground surface. The SPT N-values for the sand layers ranged from 8 to 53 blows per foot (bpi) denoting loose to very dense relative densities.. The upper sediments are underlain by layers of sandy clay (CL) and clayey sand (SC) extending to the 15-foot depth explored. The SPT N- values for the clay layers encountered ranged from 21 to 27 bpf denoting very stiff consistencies. The SPT N-values for the sand layers encountered ranged from 14 to 24 bpf denoting medium dense relative densities: Groundwater was not observed in the borings at the completion of drilling operations. Boring cave-in depths ranged from about 5,to 10 feet below the existing site grades. Groundwater elevations should be expected to vary depending on seasonal fluctuations in precipitation, surface water absorption characteristics, and other factors, and may be present at higher McDonald's Fieataurant MZ158 Spring lake, North CareiEna ECS Project No. 33,2002•A .Page 7 eleveitnns In the future. Also, perched water conditions may exist when absorbed surface -water becomes trapped above fine grained soils. The above paragraphs provide a general summary of the subsurface oonditions encountered at the site at the time of our exploretion. The boring fogs included in the ApjSendix contain detailed infonna#Eon regarding the aubsurfare conditions encountered at each goring location, The stratitimbon lines on the boring records designate approximate boundaries between various subsurface:stnft, The actual, in -situ transitions are expected to be. more gradual, McDonald's Restaurant #32.1588 Spr1rrg Lake, North Carolina ECS Project No. 33:2002-A Page 8 + • , +I�1I+'i[+L`b' Ial: �I�liT�Irrrp�I.iiTlirTig� The following design and construction recommendations are based on our above -stated understanding of the proposed construction and on the data obtained from the field exploration and visual soil classification. If the structural loading, geometry, or proposed building location is changed, we request -the opportunity to review our recommendations in light of the new information and revise them as necessary. The following recommendations are for design purposes and may require modification. Any environmental or contaminant assessment efforts are beyond the scope of this geotechnical exploration. 5.1 Site and Subgrade Preparation Site preparation should commence with the demolition and removal of the existing asphalt paved access road, and the clearing and stripping of all vegetation, topsoil, debris, deleterious materials, and any other soft or unsuitable.materials from the existing ground surface. These operations should -extend at least 10 feet beyond the limits of the planned building and pavement construction, where practical. Topsoil stripping depths on the order of fi inches should beanticipated. Abandoned underground utilities within the proposed building and pavement areas should be removed including bedding and backfill materials, Excavations resulting from underground utility removal should be backfilled with structural fill_ Pockets of trapped water could be encountered in utility trench excavations and during the removal of underground structures and should be promptly removed. Pumping from a sump pit.located within the excavation should be an effective method of controlling such groundwater seepage. Soft wet soils remaining in the bottoms of excavations should be undercut and removed to establish firm subgrade conditions prior to backfilling. The undercut areas should be backfilled with compacted structural fill. Qnce.the site is cleared and stripped as outlined above, we recommend that areas at grade and areas to be filled be thoroughly proofrolled. The proofrolling should be accomplished using a loaded dump truck having an axle weight of -at least 10 tons or'rubber-tired equipment of similar weight and tire pressures. The proofrolling should be observed by an experienced geotechnical engineer, or his representative, at the time of construction to aid in identifying any areas with soft or unsuitable materials. Repair of soft or unsuitable areas may include undercutting, moisture conditioning, and re -compacting; stone stabilization; a combination of activities, or other measures that may be appropriate. The ECS geotechnical engineer should determine the most appropriate remedial method at the time of construction_ The preparation of fill subgrades, as well as the proposed building or pavement subgrades, should be. observed on a full-time. basis by ECS personnel. These observations should be performed by an experienced geotechnical engineer, or his representative, to ensure that unsuitable materials have been removed and that the prepared subgrade is suitable for support of the proposed construction and/or fills. The natural soils at this site will deteriorate when exposed during inclement weather. The exposed subgrades should be sealed and sloped to promote surface runoff and reduce the ponding of water. When rainfall is anticipated during grading operations, .we recommend that areas of disturbed soil be sealed using a smooth drum roller or rubber -tired equipment to help reduce the infiltration of water and grading activities cease until the site has had a chance to McDonald's Restaurant#32-1588 Spring Lake, North Carolina ECS Project No. 33.2002-A Page 9 dry. Water that may accumulate in the footing excavations as a result of rainfall or surface water runoff should be immediately removed. Loosened or disturbed materials at the base of footing excavations should be removed prior to the placement of reinforcing steel or concrete. Grading operations at this site should be more economical if performed during the drier periods of the year (typically April to 'October). During the drier periods of the year, wet soils may be dried by using discing operations or other drying procedures to obtain moisture contents necessary to achieve required degrees of compaction. In the warmer summer months,.wetting of the soils may be necessary to achieve the required degree of compaction., Regardless, the earthwork contractor shall maintain the site soils within their working range of optimum. 5.2 Engineered Fill Following the removal of soft or otherwise unsuitable surface and subsurface features, and after achieving a competent subgrade, the contractor can place and compact approved, controlled engineered fill to achieve the desired site grades. The fill for support of the proposed construction and backfill for utility lines within the building and pavement limits should consist of an approved material, free of organic matter and debris. The fill materials should have a plasticity index less than 25 and a liquid. limitless than 50. We also recommend that fills within structural areas have a modified Proctor (ASTM D 1557) maximum dry density of at least 105 pounds.per cubic foot (pcf). The majority of the near -surface soils appear suitable for re -use as engineered fill provided they can be properly moisture conditioned. Prior to the commencement of fill operations ,and/or utilization ofany off -site borrow materials, .the contractor should provide representative samples of the soil materials_to the geotechnical engineer. The geotechnical engineer will. determine the material's suitability for use as an engineered fill and develop moisture -density relationships -in accordance with the recommendations provided herein. Samples should be provided to the geotechnical engineer at least 3 days prior to their use in the field to allow for the appropriate laboratory testing to be performed. Mass areas of engineered fill placed within the building and pavement areas should be placed in lifts not exceeding 8 inches in loose lift thickness and moisture conditioned to within their working range of optimum moisture content, and compacted to a minimum of 95 percent of their modified Proctor maximum dry density, as determined in accordance with ASTM D 1557. Similarly, isolated areas of engineered fill, such as trench backfill, should be placed in lifts not exceeding 4 to C inches'and moisture conditioned as mentioned above. The typical working range of moisture is typically within approximately 3 percent of the optimum moisture content. Th* footprint of the proposed building -area should be well defined during fill placement. Grade controls should also be maintained throughout the filling operations. The filling operations should be observed on a full-time basis by an experienced soils engineering technician to determine that the required degrees of compaction are being achieved. Due to the relatively small site area, -we recommend that a minimum of one compaction test per 2,500-square-foot area or fraction thereof, be performed for each lift of controlled fill. We also recommend at least one test per lift for every 100 linear feet.of utility trench, or fraction thereof. The elevation and location of the tests should be accurately identified at the time of fill placement. Areas which fail to achieve the required degree of compaction should be re-compactedand re -tested until the required compaction is achieved. Failing test areas may require moisture adjustments or other suitable remedial activities In order to achieve the required compaction. McDonald's Restaurant #32-1588 Spring 1-ako, North Carolina ECS Project N8. 33:2002-A Page 10 Fill materials should not be placed on frozen soils or frost -heaved soils and/or soils which have been recently subjected to precipitation. Borrow fill materials should not contain wet or frozen materials at the time of placement. Wet or frost -heaved soils should be removed prior to placement of engineered fill', granular sub -base materials, foundation or slab concrete, and asphalt pavement materials. Ff problems are encountered during the site grading operations, or if the actual site conditions differ from those encountered during our subsurface exploration, ECS should be notified immediately. 5,1 Foulhda#ions' Provided the subgrade preparation and earthwork operations are completed in accordance with the "Site and Subgrade Preparation" and "Engineered Fill" sections of this report, the. proposed construction can be supported on shallow foundations bearing on approved natural soils or properly prepared new engineered fills. A net allowable bearing pressure of 2,500 pounds per square foot (psf) is recommended for use in foundation design. To, reduce. the possibility of foundation bearing failure and excessive settlement due to local shear or "punching" failures, we recommend that continuous footings have a minimum width of 18 ,inches and that isolated column footings have a minimum lateral dimension of 24 inches. We recommend the bearing elevation for all exterior foundations be at a minimum depth of 18 inches below the finished exterior grade. The interior foundations should bear at least 12 inches below the floor slab. The net allowable bearing pressure refers to that pressure which may be transmitted to the foundation bearing soils, in excess of the final' surrounding overburden pressure. The foundation subgrades should be evaluated by ECS personnel to verify that the bearing soils are capable of supporting the recommended net allowable bearing pressure and suitable for foundation construction. These evaluations should include visual observations, hand rod probing, and dynamic cone penetrometer (ASTM STP-399) testing, or other methods deemed appropriate by the geotechnical engineer at the time of construction. These evaluations should be performed within each column footing excavation and at intervals not greater than 25 feet in continuous footing excavations. The settlement of a structure is a function of the compressibility of the bearing materials, bearing pressure, actual structural loads, fill depths, and the bearing elevation of footings with respect to the final ground surface elevation. Estimates of settlement for foundations bearing on engineered or non -engineered fills are strongly dependent on the quality of fill placed. Factors which may affect the quality of fill include maximum loose lift thickness of the fills placed and the amount of compactive effort placed on each lift. For foundations, b earin g on new engineered fill or approved on -site natural soils, we estimate total settlements for the proposed construction to be on the order of 1-inch, and the differential settlement to be approximately '/2 of the total settlement. This evaluation is based on our engineering experience and the anticipated structural loadings for this type of structure, and is intended to aid the structural engineer with the design. Exposure to the environment may weaken the foundation bearing sails if the foundation excavations remain exposed during periods of inclement weather. Therefore, we suggest that foundation concrete should be placed the same day that proper excavation is achieved and the McDonald's Restaurant #32-1589 Spring Lake, North Carolina ECS Project No. 13:2002-A Pago 11 design bearing pressure verified. If surface water absorption or exposure to the environment softens the foundations and slab subgrade soils, the softened soils must be removed prior to placement of concrete. If foundation excavations must remain open overnight, or if inclement weather becomes imminent while the foundation bearing soils are exposed, we recommend that a 3 inch thick "mud -mat" of "lean" concrete be placed over the exposed bearing soils before the placement of reinforcing steel, 5.4 Concrete Slabs -On -Grade Provide a suitable subgrade has been prepared as recommended herein, ground level slabs can be constructed as slabs -on -grade. Our findings ,indicate that a modulus of subgrade reaction (ks) of 125 pci is appropriate for design provided the subgrade is prepared in accordance with the "Site and Subgrade Preparation" and "Engineered Fill" sections of this report. The floor slabs should be nominally reinforced with welded wire fabric for shrinkage crack control and to help maintain the integrity of the slabs should minor differential movement occur. As'an alternative, polyester fibers (fiber mesh) may be used; however fibers should be batched/mixed at the plant and not at the site. In addition, 'the structural engineer must determine the dosage quantity of fiber to be added. in order to allow some. relative displacement, the floor slabs should be structurally separated from both columns and load bearing walls. In addition, slabs should be provided with sufficient joints to control cracking associated with concrete volume changes. To reduce curling of the floor slab and resulting cracking, proper curing techniques should be used. ECS recommends the. following 28-day concrete strengths for different applications. where repeated traffic and heavy traffic is anticipated at least 4,000 psi 'concrete; for dumpster pad, handicap parking, and ramps 3,500 psi concrete; and for side walks and interior building slabs at,least 3,000 psi concrete, We recommend that a capillary cutoff layer be provided under the floor slabs to prevent the rise of moisture to the slab. The capillary layer should consist,�at a minimum, of a 4-inch thick clean sand, crushed stone or washed gravel layer, having a maximum size of 1.5 inches with a maximum of 2 percent passing the No. 200 sieve. A vapor barrier should be utilized on top of the aggregate to provide additional moisture protection. This vapor barrier should be placed immediately before the placement of the floor slab concrete to help minimize damages. Prior to placing the aggregate for the capillary cutoff layer, the floor slab subgrade soil should be property compacted, free of standing water or mud, and unyeilding during a final proofro.11. 5.5 Pavement Considerations Pavement subgrades should be prepared in,accordance with the recommendations in the "Site and Subgrade Preparation" and "Engineered Fill" sections of this report. We were. provided with vehicle counts Information associated with the traffic volume at the facility, as 2,500 automobiles per day and a maximum of 4 trucks per day. This corresponds to 10,000 and 100,000 18-kip equivalent single axle loadings (ESA!_S) for light -duty and medium -duty pavements, respectively. In addition, McDonald's minimum pavement requirement is 3 inches of asphalt an 6 inches of compacted ABC stone. In the parking and service drive areas, we. recommend that the pavements be designed as flexible pavements using guidelines established by the American Association of State Highway McDonald's Restaurant #32-1588 Spring Lako, North Carolina ECS Project No. 33:2002-A Page 92 and Transportation Officials (AASHTO). One California Bearing Ratio (CSR) test was performed on a sample of the native subgrade soils consisting of silty sand- However, a single soil type or subgrade condition is not expected to prevail. Based on experience with the various. subgrade conditions anticipated across the site -and the results of our laboratory tests performed, we expect that the subgrade conditions will provide a minimum CBR value of about 8, which has been used in the thickness design of each pavement section. Based on the above CBR value and provided traffic loading conditions, various pavement sections were evaluated in general accordance to the 1993 "Guide for the Design of Pavement Structures" by AASHTO. For the purposes of this report the following pavement design criteria was used: initial serviceability index of 4.2, terminal serviceability index of 2.0, reliability level of 90 percent, and an overall standard deviation of 0.45. Ligl t.Dtity Medium Duty Portland.Cement Material Designation Asphalt Asp. t Concrete (PCC):: Pavement Pavement Pavement- Asphalt5urface Course 3.0'inches 3.0 inches - (Tv e SF.-9.5A) Portland Cement Concrete - - '6.0 Inches A re ate Base Course 6.0 Inches 8.0 Inches 6.0 inches ECS should be allowed to carefully review these recommendations and make appropriate revisions based upon the formulation of the final- traffic design criteria for the project. It is Important to note that the design sections do not account for construction traffic loadings. The asphalt concrete surface course materials, asphalt concrete binder course materials, and underlying aggregate base course materials should conform to the current North Carolina Department of Transportation (NCDOT) Standard Specifications for Roads and Structures. The aggregate base course materials beneath pavements should be compacted to at least 95 percent.of their -modified Proctor maximum dry density (ASTM D 1557). Front -loading trash dumpster trucks frequently impose concentrated front -wheel loads on pavements during loading. This type of loading typically results in rutting of bituminous pavements and ultimately pavement failures and costly repairs. Similarly, drive-thru lanes also create severe risk of rutting and scuffing. Therefore, we suggest that the pavements in trash pickup and drive-thru areas utilize a heavy duty Portland Cement Concrete (PCC) pavement section. It may be prudent'from an economical standpoint to use rigid pavement sections in all areas planned for heavy truck traffic. Such a PCC section would typically consist of 6 inches of 4,000 psi concrete over not less than 6 inches of compacted aggregate base course. Appropriate steel reinforcing and Jointing should also be incorporated into the design of all PCC pavements. An important consideration with the design and construction of pavements is surface and subsurface drainage. Where standing water develops, either on the pavement surface or within the base course layer, softening of the subgrades and other problems related to the deterioration of the pavement can be expected. Furthermore, positive drainage should reduce the possibility of the subgrade materials becoming saturated during the normal service period of the pavement. In addition, placement of 1/2-inch diameter holes drilled through catch basins at McDonald's Restaurant #i32-1588 8prfng Lake, North Carolina ECS Project No. 312302•A Page 13 or slightly above the subgrade elevation may help,facilitate base course drainage into the catch basin. 5.6 Seismic Site Class Determination and Liquefaction Potential Based on Section1613 of the 2012 North Carolina State Building Code, and the ReMi Survey performed, a Seismic Site Class "C" may be used for design. A weighted average shear wave velocity (Vs3o) of 1,581.3 ft/sec was measured. Based on the, subsurface conditions encountered in the soil test borings and expected ground motions at the site, the potential, for liquefaction at the site is considered low. 5.7 Site Drainaae Positive drainage should be provided around the perimeter of the building structure to reduce, the potential for moisture infiltration into the foundation and/or subgrade soils. We recommend, that landscaped areas adjacent to these structures be sloped away from the construction and maintain a fall of at least 6 inches for the first 10 feet outward from the structures. Similarly, all roof drains should drain,a sufficient distance from the building perimeter or discharge directly into below ground stormwater piping. The parking lots, sidewalks, and other paved areas should also be sloped to divert surface water away from the proposed -building. 5.8 Construction Considerations It is imperative to maintain good site drainage during earthwork operations to help maintain the integrity of the surface soils. The surface of the site should be kept properly graded to enhance drainage of surface water away from the proposed construction areas during the earthwork phase of this project. We recommend that surface drainage be diverted away from the proposed building and pavements areas without significantly interrupting its flow. Other practices would involve sealing the exposed soils daily with a smooth -drum roller at the end of the day's work to reduce the potential for infiltration of surface water into the exposed soils. Once the final subgrade elevation is established, the required thickness of ABC stone should be placed. The key to minimizing disturbance problems with the soils is to have proper control of the earthwork operations. Specifically, it should be the earthwork contractor's responsibility to maintain the site soils within a workable moisture content range to obtain the required In -place density and maintain a stable subgrade. Scarifying, drying and construction phase dewatering operations should be included in the contractor's price and should not be considered extra. In addition, construction equipment cannot be permitted to randomly move across the site, especially once the desired final grades have been established. Construction equipment should be limited to designated lanes+ and areas, especially during wet periods, to help reduce disturbance of the site subgrades. McDonald's Restaurant #32-1588 Spring Lake, North Carolina ECS Project No. 33-2002-A Page 14 6.0 CLOSING This report has been prepared in accordance with generally accepted geotechnical engineering practice. No other warranty is express or implied. Our evaluation of foundation support conditions has been based on our understanding of the site and project information and the data obtained in our exploration. The general subsurface conditions utilized in our foundation evaluation have 'been based on interpolation of subsurface data between the borings. In evaluating the boring data, we have examined previous correlations between penetration resistance values. and foundation bearing pressures observed in soil conditions similar to those at the site. If the project information Is incorrect or if the structure location (horizontal or vertical) and/or dimensions a're changed, please contact us so .that our recommendations can be reviewed. The discovery of any site or subsurface. conditions during construction which deviate from the data outlined in this exploration should be reported to us for our evaluation. Once the new construction is sited and the project grading plan has been established, ECS should be contacted to review our recommendations and .provided revisions, as necessary. Furthermore, ECS: shall be provided a copy of the final, plans and specification in advance of construction to verify that our recommendations have been correctly .interpreted. ECS is also performing a Phase I Environmental Site Assessment for the subject site and the report of finding will be submitted under separate cover.
