Report of Subsurface Exploration and GeotechniGal Vngineering Services Summit Healthcare Medical Office Building ECS Project Number 33:1876 Rev.1 June 6, 2012 EXECUTIVE SUMMARY ECS Carolinas, LLP (ECS) has completed a report of subsurface exploration and geotechnical engineering services for the proposed Summit Healthcare Medical Office Building. The site planned for development is an undeveloped tract of land located on the east side of Tilghman Drive in Dunn, North Carolina. This summary should not be considered apart from the entire text of the report with all the qualifications and conditions mentioned herein. The project entails the construction of a new Summit Healthcare Medical Office Building at the site. Based on the provided Site Plan, the building will be located in the southwest portion of the site. The building will be a single story structure with a concrete slab -on -grade floor. Structural loading information was not furnished. From our experience with similar structures, we have assumed that maximum column and wall loads will not exceed 150 kips and 3 kips per linear foot, respectively. We have assumed the floor load will not exceed 200 pounds per square foot. Other improvements to the site include paved service drives and parking areas for employees and patients. A site -grading plan was not furnished for our review at the time this report was prepared. Based on the existing site topography, we assume that earth cuts and fills will be on the order of 2 feet or less to establish the building and pavement design elevations. The subsurface conditions at the site were explored by drilling seven (7) soil test borings (borings B-1 through B-7). Borings B-1 through B-4 were completed in the proposed building area, boring B-5 was in the proposed pavement areas, boring B-6 was completed in the proposed sand filter area, and boring B-7 was completed within the eastern portion of the site. The borings in the building area were advanced to depths of about 15 feet below existing site grades with the exception of B-1, which was advanced to a depth of about 60 feet. The borings in the pavement areas, sand filter area, and within the eastern portion of the site were advanced to depths of about 7-'/z feet below existing site grades. One bulk sample of the soils anticipated to be used as pavement subgrade was obtained for laboratory testing. In addition, two in -situ infiltration tests and seasonal high water table (SHWT) determinations (1-1 through 1- 2). 1-1 was completed at the proposed sand filter and 1-2 was completed near the eastern boundary of the site. Borings B-2, B-4, B-6, and B-7 initially penetrated a surficial layer of topsoil. The topsoil was about 2 to 12 inches thick and consists of brown silty sand with fine roots and organic matter. The topsoil thickness will likely differ at other locations. Gravel was encountered at the ground surface in borings B-1, B-3, and B-5. The gravel was about 2 inches thick. The natural site soils are Coastal Plain sediments of sand and clay strata extending to the 7-'/2, 15, and 60 foot depths explored. The near -surface sediments consist of clayey sand (SC), silty sand (SM), and slightly silty poorly graded sand (SP-SM) extending to depths of about 3 to 13 feet below the ground surface. The SPT N-values for these sand layers ranged from 4 to 26 blows per foot (bpf) indicating very loose to medium dense relative densities. The near surface sediments are underlain by layers sandy clay (CL), silty sand (SM), and clayey sand (SC) extending to the 60 foot depth explored. The SPT N-values for the clay layers ranged from 6 to 46 bpf denoting firm to hard consistencies. The SPT N-values for the sand layers ranged from 4 to 36 blows per foot (bpf) indicating very loose to dense relative densities. Groundwater was not observed in the borings at the completion of drilling operations. Boring cave-in depths ranged from 4 to 9 feet below the existing site grades. Based on observed conditions, color and degree of saturation of soils, it is our opinion that the long term groundwater level most likely exists at a depth of 15 feet or more below the existing site grades in the western half of the site and at a depth of 7 feet or less below the existing site grades in the eastern half of the site. Based on the in -situ infiltration tests, the apparent seasonal high water table (SHWT) ranged from 6 to 36 inches below existing site grades and the infiltration rate was 0.001 inches per hour at a depth of 10 and 12 inches below existing site grades. The loose surface sands encountered at borings B-1 through B-5 are judged to be unsuitable for support of the building foundations, floor slab, and pavements. Shallow ground improvement using heavy compaction equipment will be necessary to achieve satisfactory subgrade conditions in areas at grade and prior to fill placement in the building and pavement areas. After the subgrade has been prepared as recommended in Section 6 of this report, the proposed building may be supported on conventional shallow footing foundations and a ground - supported floor slab. An allowable design soil bearing pressure of 2,000 psf is recommended for footings placed on properly evaluated and approved natural soils, densified site soils, or engineered fill. As an alternate, footings placed to bear 4 feet below existing site grades can be designed for a maximum net allowable soil bearing pressure of 3,000 pounds per square foot (psf). Based on the 2009 Edition of the International Building Code (IBC 2009), the weighted average of N-values from standard penetration testing resulted in a seismic site class of'D". Report of Subsurface Exploration and Geotechnical Engineering Services Summit Healthcare Medical Office Building ECS Project Number 33:1976 Rev.1 June 6, 2012 1.0 PROJECT OVERVIEW 1.1 Project Description and Scope of Work This report presents the results of the subsurface exploration and geotechnical engineering services for the proposed Summit Healthcare Medical Office Building. The site planned for development is an undeveloped tract of land located on the east side of Tilghman Drive in Dunn, North Carolina. We have been provided Site Plan which illustrates the proposed site layout, existing grades, and other site features. The subsurface conditions at the site were explored by drilling seven (7) soil test borings (borings B-1 through B-7). Borings B-1 through B-4 were completed in the proposed building area, boring B-5 was in the proposed pavement areas, boring B-6 was completed in the proposed sand filter area, and boring B-7 was completed within the eastern portion of the site. The borings in the building area were advanced to depths of about 15 feet below existing site grades with the exception of B-1, which was advanced to a depth of about 60 feet. The borings in the pavement areas, sand filter area, and within the eastern portion of the site were advanced to depths of about 7-'/2 feet below existing site grades. One bulk sample of the soils anticipated to be used as pavement subgrade was obtained for laboratory testing. In addition, two in -situ infiltration tests and seasonal high water table (SHWT) determinations (1-1 through I- 2). 1-1 was completed at the proposed sand filter and I-2 was completed near the eastern boundary of the site. The soil test borings and infiltration tests were located in the field by ECS personnel using measurements off existing site features. The approximate boring and infiltration test locations are shown on the Boring Location Plan provided in Appendix A of this report. The ground surface elevations at the boring and in -situ infiltration/SHWT test locations were interpolated from topographic information provided on the Site Plan and should be considered approximate. In conjunction with the soil borings, laboratory testing was performed to help characterize the soil samples obtained from the drilling operations. This report was prepared based upon the results of the boring and laboratory data. The purpose of this exploration is to describe the soil and groundwater conditions that were encountered in the test borings, to analyze and evaluate the test data obtained, and to submit recommendations regarding foundations, slabs, pavements, earthwork, construction, and other geotechnical-related considerations of design and construction. 1.2 Proposed Construction ECS understands that the proposed entails the construction of the Summit Healthcare Medical Office Building at the site. Based on the provided Site Plan, the building will be located in the southwest portion of the site. The building will be a single story structure with a concrete slab - on -grade 'floor. Structural loading information was not furnished. From our experience with similar structures, we have assumed that maximum column and wall loads will not exceed 150 kips and 3 kips per linear foot, respectively. We have assumed the floor load will not exceed 200 pounds per square foot. Other improvements to the site include paved service drives and parking areas for employees and patients. Report of Subsurface Exploration and Geotechnical Engineering Services Summit Healthcare Medical Office Building ECS Project Number 33:1976 Rev.1 June 6, 2012 A site -grading plan was not furnished for our review at the time this report was prepared. Based on the existing site topography, we assume that earth cuts and fills will be on the order of 2 feet or less to establish the building and pavement design elevations. If actual loads and fill heights exceed these assumptions, ECS should be allowed the opportunity to reassess our recommendations. Report of Subsurface Exploration and Geotechnical Engineering Services Summit Healthcare Medical Office Building ECS ProJect Number 33:1976 Rev.1 June 6, 2012 2.0 FIELD EXPLORATION 2.1 Soil Test Borings The soil test borings were completed using a truck -mounted CME 45 drilling rig. The borings were advanced using 2-'/ inch I.D. hollow -stem augers. Drilling fluid was not used to advance the borings. Representative soil samples were obtained by means of the split -barrel sampling procedure in general accordance with ASTM Specification D-1588. In this procedure, a 2-inch O. 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 and were brought to our laboratory for further examination and testing. 2.2 Infiltration Test Procedures The subsurface soil and groundwater conditions at the infiltration test locations were explored by advancing a hand auger boring. The groundwater level and the seasonal high water table (SHWT) observed in each hand auger boring at the time of drilling was recorded. An infiltration test utilizing a compact constant head permeameter was conducted near each hand auger boring to estimate the infiltration rate for the subsurface soils. Infiltration tests are typically conducted at two feet above the SHWT. If the SHWT is less than three feet, the test is conducted at ten inches below the surface elevation. Report of Subsurface Exploration and Geotechnical Engineering Services Summit Healthcare Medical Office Building ECS Project Number 33:1976 Rev.t June 6, 2042 3.0 LABORATORY TESTING 3.1 Laboratory Testing Program Laboratory tests were performed on a representative portion of the soil samples obtained during the exploration. These included tests for natural moisture content, Atterberg limits, and percent of particles finer than the U.S. Standard No. 200 mesh sieve. Standard Proctor compaction and California Bearing Ratio (CBR) tests were performed on the bulk sample to aid in evaluating the on -site soils for use as pavement subgrade. The data obtained from the laboratory tests are included in the Laboratory Testing Summary in Appendix C of this report. The soil samples collected for this exploration will be retained at our laboratory for a period of sixty days, after which they will be discarded unless other instructions are received as to their disposition. 3.2 Visual Classification An engineer classified each soil sample on the basis of texture and plasticity in accordance with the Unified Soil Classification System (USCS). The group symbols for each soil type are indicated in the parentheses following the soil descriptions on the boring logs. A brief explanation of the USCS is included in Appendix B of this report. The engineer grouped the various soil types into the major zones noted on the boring logs. The stratification lines designating the interfaces between earth materials on the boring logs are approximate; in -situ, the transitions will be gradual and/or at slightly different elevations/depths. 3.3 Laboratory Testing Methods 3.3.1 Moisture Content Tests ASTM Designation D2216 gives the standard procedure for determining the moisture content of soil. The moisture content is defined as the ratio of the weight of water to the weight of solids in a given soil mass and is usually expressed as a percentage. The moisture content is determined by weighing a soil sample, thoroughly drying it at a specified temperature, and weighing it after drying. 3.3.2 Atterberg Limits ASTM Designation D4318 gives the standard procedure for determining the Plastic and Liquid Limits of soil. The sample for the Liquid and Plastic Limit tests is prepared by removing any material larger than the #40 (425pm) sieve. The Liquid Limit test is determined by performing multiple trials in which a portion of the prepared sample is spread in a cup (of specified material and dimensions), divided by a grooving tool, and allowed to flow together a distance of 1/2 inch by the force of repeatedly dropping the cup in a standard mechanical device. Data from the multiple trials is plotted with the water content on the y-axis and the number of drops required to close the groove on the x- Report of Subsurface Exploration and Geolechnical Engineering Services Summit Healthcare Medical Office Building ECS Project Number 33:1976 Rev.1 June 6, 2012 axis. The Liquid Limit is defined as the water content at which 25 drops are required to close the groove made in the soil. The Plastic Limit is determined by roiling a small portion of the prepared soil sample to a thread with a uniform diameter of 118 inch. The thread is rolled into a ball and rerolled into a thread with a uniform diameter of 118 inch. The process is repeated until the thread crumbles and can no longer be rolled into a thread. The water content of the soil at this point is the Plastic Limit. The Plasticity Index is defined as the difference between the Liquid Limit and the Plastic Limit. 3.3.3 Percent of Particles Finer Than the U.S. Standard No. 200 Mesh Sieve ASTM Designation D1140 gives the standard procedure for determining the amount of material in a soil finer than the No. 200 (75-microns) sieve. The sample is dried, soaked in water, agitated, and poured over the No. 200 sieve. The material retained on the No. 200 sieve is dried, and weighed. The No. 200 sieve represents the boundary in the Unified Classification System between coarse grained soils (sand) and fine grained soils (silt and clay). 3.3.4 Standard Proctor ASTM Designation D698 gives laboratory compaction procedures to determine the relationship between the water content and dry unit weight of soils. The test is performed by placing three layers of soil at a selected water content into a mold of specified dimensions and compacting each layer 25 times with a 5.5-pound rammer. The rammer is dropped a distance of 12 inches and subjects the soil sample to a total compactive Effort of approximately 12,400 ft-Iblfta. The resulting dry unit weight is determined. This procedure is repeated for a sufficient number of water contents to establish a relationship between the dry unit weight and water content for the soil. This data, when plotted, represents a curvilinear relationship known as the compaction. 3.3.5 California Bearing Ratio (CBR) ASTM Designation D1883 gives the test method to determine the California Bearing Ratio (CBR) of pavement sub -grade sub -base and baselcourse materials from laboratory compacted specimens. This test is performed by compacting a soil sample to a specified density using laboratory compaction techniques. The sample is then soaked for 96 hours and subjected to penetration by a 2-inch diameter cylindrical piston. The stress at penetrations of 0.1 inch and 0.2 inch in the wet conditions are used to calculate the CBR values for the soil. Typically the CBR value determined for a penetration of 0.1 inch on the soaked sample is used for pavement design. Report of Subsurface Exploration and Geotechnical Engineering Services Summit Healthcare Medical Office Building ECS Project Number 33:1976 Rev.1 June 6, 2612 a 4.0 EXPLORATION RESULTS 4.1 Site Conditions The site planned for development is an approximate 7.90-acre tract of land located on the east side of Tilghman Drive in Dunn, North Carolina. The site is bounded by the office buildings to the north and south, wooded tracts of land to the east, and Tilghman Drive to the west. The site is currently undeveloped. The ground surface in the western half of the site is covered with grass and gravel. Ground cover in the eastern half of the site consists of grass, brush, and small isolated pine trees. A large stockpile of soil is located in the southeast portion of the site. The topography of the site varies in elevation by about 10 feet_ The site is highest in elevation along the western boundary (Tilghman Drive) at about elevation 100 feet and slopes downward to the east-northeast to an elevation low of about 90 feet at the near the northeast corner of the site. The estimated elevation differential in the western half of the site across the proposed building and pavement areas is 1 to 2 feet. The current site grades are generally consistent with the surrounding topography. 4.2 Site Geology and Subsurface Conditions 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 Mountain 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 Soil Conditions The specific soil conditions at each boring location are noted on the individual boring logs presented in Appendix B. A general description is also provided below. Subsurface conditions can and often do vary between boring locations and in unexplored areas. Borings B-2, B-4, B-6, and B-7 initially penetrated a surficial layer of topsoil. The topsoil was about 2 to 12 inches thick and consists of brown silty sand with fine roots and organic matter. The topsoil thickness will likely differ at other locations. Gravel was encountered at the ground surface in borings B-1, B-3, and B-5. The gravel was about 2 inches thick. The natural site soils are Coastal Plain sediments of sand and clay strata extending to the 7 '/2, 15, and 60 foot depths explored. The near -surface sediments consist of clayey sand (SC), silty sand (SM), and slightly silty poorly graded sand (SP-SM) extending to depths of about 3 to 13 feet below the ground surface. The SPT N-values for these sand layers ranged from 4 to 26 blows per foot (bpf) indicating very loose to medium dense relative densities. The near surface sediments are underlain by layers sandy clay (CL), silty sand (SM), and clayey sand (SC) Report of Subsurface Exploration and Geotechnical Engineering Services Summit Healthcare Medical Office Building ECS Project Number 33:1976 Rev.1 June 6, 2012 extending to the 60 foot depth explored. The SPT N-values for the clay layers ranged from 6 to 46 bpf denoting firm to hard consist6.ncies. The SPT N-values for the sand layers ranged from 4 to 36 blows per foot (bpf) indicating very loose to dense relative densities. 4.4 Groundwater Groundwater was not observed in the borings at the completion of drilling operations. Boring cave-in depths ranged from 4 to 9 feet below the existing site grades. Based on observed conditions, color and degree of saturation of soils, it is our opinion that the long term groundwater level most likely exists at a depth of 15 feet or more below the existing site grades in the western half of the site and at a depth of 7 feet or less below the existing site grades in the eastern half of the site. Seasonal variations in groundwater levels should be anticipated due to precipitation changes, evaporation, surface water runoff, and other factors. Also, perched water conditions may exist when absorbed surface water becomes trapped above fine grained cohesive soils. Based upon the in -situ testing performed; the following seasonal high water table and infiltration rates were obtained: Location ID Depth I-1 0 to 36" 36" to 84" 84" to 90" Soil Description Tan/orange fine SAND wl clay Tanlorange/red mottled sandy CLAY Tan/orange/gray CLAY wl sand Seasonal High Water Table was estimated to be at 36 inches below the existing grade elevation (approximate elevation 96 feet). 40 ; r` I c_r_mA rrojr }POOL = G5•�i .jll' 0.5 Infiltration Rate: 0.001 inches per hour Test was conducted at 12 inches below existing grade elevation.

Report of Subsurface Exploration and Geotechnical Engineering services Summit Healthcare Medical Office Building ECS Project Number 33:1976 Rev.1 June 6, 2012 5.0 ANALYSIS AND RECOMMENDATIONS 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 exploration. 5.1 Foundations After the subgrade has been prepared as recommended below and in Section 6 of this report, support of the proposed building , may be achieved using conventional shallow spread foundations bearing directly upon properly evaluated and approved natural soils, densified site soils, and/or properly compacted structural fill. Foundations may be proportioned for a maximum net allowable soil bearing pressure of 2,000 pounds per square foot. As an alternate, footings placed to bear 4 feet below existing site -grades can be designed for a maximum net allowable soil bearing pressure of 3,000 pounds per square foot (psf). The exterior foundations should bear at least 18 inches below the adjacent exterior design grade to afford protective embedment. The interior foundations should bear at least 12 inches below the floor slab. The edges of "turned -down" slab designs should bear at least 12 inches below adjacent exterior grades. The column foundation should have a minimum width of 24 inches. The wall foundations should have a minimum width of 18 inches. The stability of the site soils encountered at the foundation bearing grades should be determined with field tests as foundation excavation progresses. As a test procedure, dynamic cone penetration (DCP) tests should be performed in the foundation excavations as determined by our project geotechnical engineer. Our project engineer should evaluate the results of the tests to ascertain that adequate soil bearing capacity is achieved. Soils loosened by the excavation process should be re -compacted to an acceptable density or hand trimmed and removed. If unsuitable materials are encountered at the base of a foundation excavation, it will be necessary to lower the base of the footing through the unsuitable materials or to undercut the unsuitable soils and to restore original bearing levels by placing engineered fill materials, No. 57 or No. 67 stone, or Plowable fill. Exposure to the environment may weaken the soils at the footing bearing levels if the foundation excavations remain open for too long a time. Therefore, foundation concrete should be placed during the same day that excavations are made. If the bearing soils are softened by surface water intrusion or exposure, the softened soils must be removed from the foundation excavations prior to placement of concrete. No foundation should be constructed on frozen subgrade. Report of Subsurface Exploration and Geotechnical Engineering Services Summit Healthcare Medical office Building ECS Project Number 33:1976 Rev.1 June 6, 2012 5.2 Settlement Total settlements of individual footings, designed in accordance with our recommendations presented in this report, are expected to be on the order of 1 inch. Differential settlement between any adjacent, similarly -loaded columns is expected to be on the order of/z inch. 5.3 Floor Slab The slab -on -grade subgrade should be prepared as outlined in Sections 6.1 and 6.2 of this report. A modulus of subgrade reaction of 125 pci is recommended for site soils or properly placed and compacted structural fill. To reduce curling of the floor slab and the resulting cracking, proper curing techniques should be used. 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 properly compacted, free of standing water or mud, and stable during a final proofroll. 5.4 Seismic Site Classification North Carolina has adopted (with State amendments) the 2009 Edition of the International Building Code (IBC 2009), and the IBC 2009 requires that a seismic Site Class be assigned for new structures. The method for determining the Site Class is presented in Section 1613.5.5 of the IBC 2009. The seismic Site Class is typically determined by calculating a weighted average of N-values from standard penetration testing in conventional soil test borings, undrained shear strengths, or the shear wave velocities of the materials in the upper 100 feet of the site. Based on the IBC 2009, the weighted average of N-values from standard penetration testing resulted in a seismic site class of "D". 5.5 Site Drainage We recommend the ground surface be sloped away from the buildings and pavements for a minimum distance of 10 feet, and that all downspouts be connected to tightline drains that discharge to a suitable location downslope of the building or discharge directly into below -grade stormwater piping. In addition, any pavement areas should have positive drainage. 5.6 Groundwater Control Based on the results of the borings, we do not anticipate that dewatering will be necessary during construction. If groundwater or a perched water condition is encountered during construction, it probably can be controlled through the use of ditches, sumps, and pumps. If water is encountered that cannot be controlled by such procedures, ECS should be further consulted. Earthwork and trench excavation in saturated materials may require sheeting and shoring, slope flattening, or benching to control sloughing of soils. 9 Report of Subsurface Exploration and Geolechnlcal Engineering Services Summit Healthcare Medical Office Building ECS Project Number 33:1076 Rev.1 June 6, 2012 If water collects in foundation excavations, it will be necessary to remove the water from the excavation, remove the saturated soils, and re -test the adequacy of the bearing surface to support the design bearing pressure prior to concrete placement. 5.7 Excavation Considerations The sidewalls of excavations should be stepped back with benches or slopes in accordance with the requirements of the most current Occupational Safety and Health Administration (OSHA) 29 CFR Part 1926, "Occupational Safety and Health Standards -Excavations." Excavation sidewalls that cannot be properly stepped back should be braced against collapse. The design of the bracing system should include lateral earth pressures and temporary surcharge loads from construction traffic and materials stockpiled next to the excavation. The design and construction of excavation bracing is typically the responsibility of the specialty subcontractor selected to install the system. Regardless, site safety shall be the sole responsibility of the contractor and his subcontractors. 5.8 Pavements Pavement subgrades should be prepared as outlined in Sections 6.1 and 6.2 of this report. We were not provided with vehicle counts and axle -loading information associated with the traffic volume at the facility. However, for purposes of this study, we have assumed that parking areas will receive primarily automobile traffic, and the entrances and service drives will be subjected to some heavy truck traffic. We have assumed traffic loads of 10,000 and 100,000 18-kip equivalent single axle loadings (ESALS) for standard -duty and heavy-duty pavements, respectively. 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 and Transportation Officials (AASHTO). A California Bearing Ratio (CBR) test was performed on the anticipated subgrade soils consisting of slightly silty sand. Based on experience with the subgrade conditions anticipated 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 assumed traffic loading conditions, various pavement sections were evaluated in general accordance to the 1993 "Guide for the Design of Pavement Structures" by the American Association of State Highway and Transportation Officials (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. 10 Report of Subsurface Exploration and Geotechnical Engineering Services Summit Healthcare Madical Office Building ECS Project Number 33.1976 Rev.1, June 6, 2012 r Heavy Duty Standard Duty Heavy Duty Portland Cement Material Designation Asphalt Asphalt Concrete (PCC) Pavement" Pavement"* Pavement** Asphalt Surface Course SF-9.5A 1.5 inches 2.0 inches - Portland Cement Concrete - - 6 inches Aggregate Base Course (NCDOT 6 inches 8 inches 4 inches ABC Note" : Geogrid such as Tensar SX1100 or woven geotextile fabric and additional stone base course materials may be necessary in localized areas to achieve subgrade stabilization. The need for such materials will be a function of subgrade conditions at the time of pavement construction. The base course materials beneath pavements should be compacted to 98 percent of their modified Proctor maximum dry density (ASTM D 1557). The asphalt concrete and crushed stone materials should conform to the North Carolina Department of Transportation Standard Specifications for Roads and Structures. For Portland Cement Concrete (PCC) pavement sections, the concrete should be plant -mixed with a minimum compressive strength of 4,000-psi at 28-days and should contain 4 to 6 percent entrained air. Appropriate steel reinforcing and jointing should be incorporated into the design of PCC pavements. Front -loading trash trucks frequently impose concentrated front -wheel loads on pavements while lifting the dumpster. This type of loading typically results in rutting of bituminous pavements and ultimately pavement failures and costly repairs. Therefore, we recommend a heavy duty PCC pavement section in the area of the trash dumpster, including the area where the front axle of the trash truck will be located while lifting the dumpster. Regardless of the section and type of construction utilized, saturation of the subgrade materials will result in a softening of the subgrade materials and shortened life span for the pavement. Risk of subgrade softening can be reduced by means of quickly removing surface and subsurface water, resulting in an increased likelihood of improved pavement performance. Therefore, we recommend that both the surface and subsurface materials for the pavement be properly graded to enhance surface and subgrade drainage. In addition,'placement of %-inch diameter holes drilled through catch basins at or slightly above the subgrade elevation will facilitate base course drainage into the catch basin. 11 AFT); W YIF NC®EN North Carolina Department of Environment and Natural Resources Beverly 'aves Perudue Governor Mr. Joe Joseph Summit Healthcare Group, LLC 390-C South Shatford Rd.
