PROJECT AND SITE INFORMATION ' 1,1 Prnjnrt Inf~rmw~~nn The proposed project consists of development of the North Carolina Center for 1 Automotive Research (NCCAR) on an approximate 650-acre tract of land in Northampton County, North Carolina. The site is located east of I-95, north of N.C. Highway 46 and south of N.C.S.R. 1202. The proposed project will consist of multiple ' construction phases. The initial phase of construction will consist of the following: • A security kiosk approximately 10 feet by 35 feet in plan dimension. Structural loads for the kiosk are unknown at the time of this report; however, wall loads less than 3 kips per linear foot and column loads less than 50 kips are anticipated. ' • An entrance road into the facility which begins at the security kiosk and continues to the beginning of the ride and handling road. The proposed entrance road will be approximately 2,500 feet long. We assume traffic along this road will consist of ' passenger vehicles, transfer trucks, and fuel trucks. We have estimated that the entrance road will be subjected to approximately 300,000 18-kip equivalent single axle loads (ESALs) over its design life. We understand the entrance road from the security kiosk to the entrance in to the site will be designed by others. • An operations and administration building with a plan area of 12,000 square feet. The building will be located near the entrance to the track area. The building will be a 1 to 2-story steel framed structure. Structural loads for the building are ' unknown at the time of this report; however, maximum column loads are assumed to be less than 150 kips. An approximately 2.03 mile ride and handling road. The road will be used by ' different types and volumes of vehicles weighing up to 45,000 pounds. The road will be designed for maximum speeds of 160 miles per hour. We understand that 100,000 18-kip equivalent single axle loads (ESALs) should be used as the design traffic loading. The paved road will be 40 feet wide with 10 feet shoulders and 100 feet of runoff area on both sides. The pavement and shoulders will have ' slopes of 1 % and 2%, respectively. The runoff area will have a design slope of 4%. Earlier plans called for a slope of 1 % on the shoulders and runoff areas; however, due to the significant importance of surface drainage at this site the grades were steepened. Open ditches will be provided beyond the runoff area for site surface drainage. We understand that due to the high speed traffic, only minimal differential settlement along the roadway can be tolerated. • A vehicle dynamics area (VDA) pad is proposed for construction on the west side of the ride and handling road. The FDA pad will be approximately 128 feet by 670 feet. The pad will be sloped at 1 % from the east to the west for surface ' drainage. Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR -Northampton County NC April 15, 2008 Based on the grading plan you have provided, proposed finish grades will range from 118 to 138 feet. Compared to existing grades at the boring locations, maximum cuts and fills of 17 and 7 feet, respectively, will be rectuired to obtain finish grades, We understand c»t and fill slopes will be constructed on inclinations of 4 (horizontal) to 1 (vertical). Areas inside the ride and handling road alignment (infield and runoff areas) will be grassed. The road shoulders will also be grassed. Four drainage ditches or swales will be constructed in the infield areas, draining to yard inlets. In these areas the Swale bottoms are at an elevation of 118 to 120 feet on the north and 115 to 118 feet on the south. We understand future development will consist of several structures, expansions of the ride and handling course, expansion of the VDA pad, and a large vehicle dynamics area. Plans for these future developments are unknown at this time. However, we understand that excavated soils not used as fill in areas of Phase I construction will be placed in the southeast portion of the future ride and handling course expansions. 1.2 Site Description The 650 acre site currently consists of planted pines on its southern portion and previously harvested woods on its northern portion. The harvested area of the site still contains some left over cut down trees and low cut stumps. In some cases trees were used to create haul roads. Areas of surface rutting from log skidders also exist. Surface water has ponded in some of these ruts. The planted areas consist of closely spaced, approximately 10 to 15 year old pine trees. A power line easement transverses the south portion of the site in an east-west direction. Low-lying, swampy areas are present along the proposed entrance road, south and west of the security kiosk. Standing and running water was present in this area during our field operations. Several low-lying areas with casual water were also observed in the harvested area on the north portion of the site. Based on provided topographic information, existing site elevations range from approximately 116 to 138 feet. For the most part the site gently slopes north to south. General site drainage is to the west and south, toward the Roanoke River. A large drainage Swale exists on the northwest portion of the property and slopes east to west. The highest portion of the site exists just south of this drainage Swale. 2. EXPLORATION PROGRAM 2.1 Soil Test Borings The subsurface exploration program for this project included a visual site reconnaissance by representatives o f S&ME and performance of 54 soil test borings and 7 test pits. Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR -Northampton County NC April 15, 2008 Boring/test pit locations were selected and located in the field by representatives of S&ME using global positioning satellite (GPS) equipment. Approximate boring locations are shown on Figure lA and 1B in the Appendix. Borings performed for this project were advanced to depths ranging from approximately 10 to 60 feet below the existing ground surface using hollow stem auger drilling procedures with a Mobile B-57 drill rig mounted on an all-terrain vehicle. Within each boring, samples of subsurface soils were taken at 2.5 foot intervals above a depth of 10 feet and at 5 foot intervals below 10 feet using asplit-spoon sampler. Standard penetration testing was performed in conjunction with split-spoon sampling in general accordance with ASTM D 1586-99. Several bulk samples of auger cuttings and one relatively undisturbed Shelby tube sample were also obtained. Groundwater levels were recorded in all boreholes after termination of drilling and in most boreholes after 24- hours. Temporary piezometers were also installed in borings T-1 and T-9 for groundwater measurements. After groundwater levels were measured, temporary piezometers were removed and boreholes were backfilled with auger cuttings and borehole closure devices. Representative portions of split-spoon, bulk, and Shelby tube samples were returned to our laboratory for visual classification and laboratory testing. Visual classification was performed in general accordance with Unified Soil Classification System (USCS) guidelines. Generalized Subsurface Profiles (Figures 2A, 2B, and 2C) and Test Boring Records presenting specific subsurface information from the borings are included in the Appendix. Stratification lines shown on Test Boring Records and Profile are intended to represent approximate depths of changes in soil types. Naturally, transitional changes in soil types are often gradual and cannot be defined at a particular depth. Ground surface elevations shown on the Test Boring Records were interpolated from the topographic information on the site plan provided. 2.2 Test Pits ' Representatives of S&ME were present at the site on January 4, 2008 to observe test pit excavations conducted using aCAT-320 track-mounted backhoe. Seven test pits were excavated by M.J. Pnce Construction Company and observed by S&ME at locations determined in the field based on encountered soil conditions. Test pits were performed in close proximity to boring locations T-3, T-5, T-18, T'-19, T-21, T-27, and T-29. Test pits were performed to depths ranging from about 6 to 16 feet below the existing ' ground surface. Encountered soils were visually classified in the field by an S&ME representative in general accordance with Unified C'tassification System (USCS) guidelines. Excavations were backfilled prior to removing the equipment from the site. Summaries of subsurface conditions encountered in test pits are shown on the Summary of Test Pit Data logs included in the Appendix. 1 1 Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR -Northampton County NC April 15, 2008 2.3 Laboratory Testing Labnratn_ testing nn selected g lit_g„nnn l~,µll{ and Sheib" tube S%uii ieS inciudird t he a 1? t,.,.,.~, > J' l,' following tests: • Natural Moisture Content (ASTM D 2216) • Grain Size Analysis (ASTM D 422) • Atterberg limits (ASTM D 4318) • Standard Proctor (ASTM D 698) • California Bearing Ratio (ASTM 1883) • In-place Unit Weight (ASTM D 2937) • One-Dimensional Consolidation Testing (ASTM D 4186) The following laboratory tests were also performed as part of the recommended lime modification program: • Eades and Grim pH (ASTM D 6276) • Standard Proctor (ASTM D 698) with 3% Lime • California Bearing Ratio (ASTM D 1883) with 3% Lime • Unconfined Compression (ASTM D 2166) with 3% Lime All laboratory tests were performed in general accordance with ASTM procedures. 3. AREA GEOLOGY AND SOIL SURVEY 3.1 Area Geology The site is located in the Coastal Plain Physiographic Province of North Carolina near its boundary (Fall Line) with the Piedmont Physiographic Province. The Coastal Plain is typically characterized by marine and eolian sediments that were deposited during periods of fluctuating sea levels and moving shore lines. Near surface soils often consist of more recent undifferentiated deposits ofinter-bedded sands, silts, and clays. Deeper deposits also consist of sands, silts, or clays but can be defined as particular formations with distinguishable characteristics and engineering properties. The geology in the area of the subject site primarily consists of Undifferentiated Surface Deposits of Quaternary Age and recent alluvial sediments. Typically, the Undifferentiated Deposits consist of silty clays underlain by silty fine to coarse sands. The deposits are underlain by the Yorktown Formation of the Middle Tertiary Age. The Yorktown Formation consists of gray-green coarse to fine sands with trace of silt, clay, and shell material. The borings did not encounter the Yorktown Formation to the depths drilled. Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR -Northampton County NC April 15, 2008 ' 3.2 Soil Survey S~r1V11?, revieyyed the Np;-thampton Co'~ntj' Soil Surve`y', issued in August 1994, tGvbtalri near surface soil classification information for the subject site. The subject site lies in an area where the upper soils consist mostly of Bonneau and Caroline Series soils. The ' survey indicated that these soils consist of well drained to slowly permeable soils that formed in clayey marine sediments in the uplands on the Coastal Plain. Slopes are typically 0 to 12 percent. These soils are typically slightly to very strongly acidic. 4. SUBSURFACE CONDITIONS Approximately 4 to 18 inches of topsoil was encountered at the existing ground surface of the boring/test pit locations. Because of the surface rutting from past logging operations the topsoil has mixed into the underlying subsoils at some locations. Thus some deeper stripping may be required in some areas. Below the topsoil, natural Coastal Plain deposits were encountered to boring termination depths ranging from about 10 to 60 feet. Natural soils near the ground surface consist mainly of highly plastic clayey silts and silty clays (USCS classifications of MH, CH). Highly plastic silts and clays extend from below the topsoil to typical depths ranging from 5 to 15 feet with the greater depths encountered on the north portion of the site. Highly plastic soils were encountered in over two thirds of the borings. Highly plastic soils were not encountered in borings T-23, T-26, T-28, T-31, T-34, T-37, T-40, R-4, R-5, R-6, G-1, O-l, and O-2. Standard penetration test (SPT) N-values in highly plastic soils ranged from 5 to 29 blows per foot indicating firm to hard consistencies. Typically the SPT values in these soils ranged from 13 to 29 bpf. The highly plastic soils encountered are typically wet of their standard Proctor optimum moisture content. Low plasticity silty and sandy clays (CL), sandy and clayey silts (ML), and silty and clayey sands (SM, SC, SP-SC) were encountered beneath the highly plastic soils. Pea gravel was encountered in several of the split-spoon samples obtained in the mostly sand layers. SPT N-values in low plasticity soils ranged from 3 to 37 blows per foot. Recorded N-values indicate very loose to dense relative densities for sands and firm to hard consistencies for silts and clays. The low plasticity soils encountered are typically wet of their standard Proctor optimum moisture content. Groundwater levels were recorded in all borings after termination of drilling and in most borings after 24 hours. Temporary piezorneters were installed in borings T-1 and T-9 and were measured and removed several days after drilling. Seepage of water through excavation side walls was also recorded during test pit excavation. Groundwater levels recorded range from approximate depths of 3.5 to 19 feet below the existing ground surface or elevations of 108 to 131 feet. Groundwater levels in anticipated cut areas range Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR -Northampton County NC April 15, 2008 from approximately 4.6 to 21.6 feet below existing ground surface. Groundwater levels were encountered above proposed final grades in borings T-7, T-17, T-18, T-19, and T- 29. In addition to the above borings groundwater was encountered within 2 _feet of design subgrade at T-S. Based on proposed final grades and groundwater levels encountered at the time of our field exploration, excavations at the boring locations could extend as much as 2.S to 10 feet below current groundwater levels. Prior to our exploration most of North Carolina has experienced severe drought conditions and the recorded water levels could be at historical lows. When normal rainfall returns the groundwater levels could rise several feet above the current levels. Perched water was observed in the test pits above highly plastic materials. Because of the ' soil conditions at this site, perched water should be anticipated in almost any area. Due to the blocky structure of some of the clays, some perched water or groundwater was encountered in these soils. 5. LABORATORY TESTING Laborato testin consisted of natural moisture content, Atterberg limits, grain size rY g analysis, standard Proctor, California Bearing Ratio (CBR), in-place unit weight, and consolidation testing. As part of our recommended lime modification program Eades- Grimm pH tests along with standard Proctor, CBR, and unconfined compression tests were performed on samples having 3 percent quicklime added. Summary tables of ' laboratory test results along with laboratory test records are included in the Appendix. Natural moisture contents of tested soils range from 18.2 to 34.1 percent. Tested samples above the groundwater table range from 18.2 to 33.7 percent and below the groundwater from 18.7 to 34.1 percent. Natural moisture contents of highly plastic clays and silts range from 21.4 to 33.7 percent. The average and median moisture content of the tested highly plastic soils was 29 percent. Atterberg limits testing on selected samples indicates liquid limits (LL) ranging from 31 to 79 percent, plastic limits (PL) ranging from 17 to 41 percent, and plasticity indices (PI) ranging from 13 to 47 percent. The highly plastic soils (having LLs greater than SO% and PIs greater than 30%) had an average LL of 67%, PL of 32%, and PI of 36%. Highly plastic soils with liquid limits greater than 50 percent and plasticity indices greater than 30 percent can shrink and swell with changes in moisture content, which can cause uplift or shrinkage damage to pavements or light buildings if not properly addressed. Grain size analysis testing was performed on bulk samples obtained from borings T-6 (17 to 22 feet below existing ground surface), T-10 (1 to S feet), and T-13 (1 to S feet). Samples tested from borings T-10 and T-13 contain mostly fine grained soils with 50.8 to ' 57.5 percent clay, 38.5 to 42.2 percent silt, and 4 to 7 percent sand. Based on the above Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR -Northampton County NC April 15, 2008 ' clay contents and PIs, these two samples have an activity, which is the water holding ability of the clay minerals, of 0.61 and 0.69. These are low activities and suggest the clay ' is a kaolinite. The sample tested from boring T-6 contains mostly coarse grained soil with 56.2 percent sand and 43.8 percent fines (silt and clay). Standard Proctor compaction testing on bulk samples of on-site borrow materials indicate maximum dry densities ranging from 95.7 to 115.1 pounds per cubic foot (pct with corresponding optimum moisture contents (OMC) ranging from 13.7 to 23.7 percent. Natural moisture content testing performed on these bulk samples indicate natural ' moisture contents ranging from 22.2 to 32.5 percent. Natural moisture contents of these bulk samples range from approximately 2 to 16 percent wet of their OMC. The wetter ' soils were those sampled below the water table, however even those soils above the water table had natural moistures 4 to 10 percent above their OMC. The average of all moisture samples relative to their OMC was 6 percent wet with a similar average wet of OMC value for the plastic clays and silts. Looking at the wet side of the Proctor curves, 95 and 92 percent compaction could be obtained at moistures 3 and 5 percent wet of OMC, respectively. However, at these moistures some instability and rutting in the fill under heavy rubber tired construction traffic should be expected. California Bearing Ratio (CBR) testing was performed on untreated bulk specimens recompacted to approximately 98 percent of their standard Proctor maximum dry density. The test specimens were recompacted at moisture contents near their optimum moisture content. The specimens were then soaked for 96 hours during which swell values of 0.1 to 4.6 percent were recorded. Swell values recorded for the highly plastic soil samples (with the exception of the sample from boring T-6) range from 2.7 to 4.5 percent. A$er soaking, CBR values ranging from 1.3 to 9.6 percent were recorded. CBR values for highly plastic soil specimens range from 1.3 to 4.6 percent. ' In-place unit weight testing was performed on a relatively undisturbed Shelby tube sample obtained from boring G-1 at approximate depths ranging from 1.5 to 3.5 feet. In- place moist and dry unit weights of 126.8 and 107.0 pcf were recorded. e 1 Consolidation testing was performed on the relatively undisturbed Shelby tube sample obtained from boring G-1 and bulk sample obtained from the test pit performed near boring T-5. The bulk sample from the test pit performed near boring T-5 was recompacted to both 92 and 95 percent of its standard Proctor maximum dry density on the wet side of its OMC. The sample from boring G-1 was saturated prior to loading. The following table presents consolidation test results including compression indices (Cc) and coefficients of consolidation (Cv}.

Based on this testing approximately 2 and 3 percent Quicklime by weight is required to reach a pH level of 12.4 for the highly plastic silt and highly plastic clay samples, ' respectively. Standard Proctor tests were performed on the bulk samples obtained from borings T-10 anal T-13, each mixed with 3 percent Quicklime. Standard Proctor maximum dry densities of lime amended soils range from 92.7 pcf for the highly plastic silt sample (95.7 pcf ' without lime) to 95.4 pcf for the highly plastic clay sample (98.2 pcf without lime). Optimum moisture contents of the lime amended soils range from 25.6 percent for the highly plastic clay sample (23.6% without lime) to 27.0 percent for the highly plastic silt sample (23.7% without lime). California Bearing Ratio (CBR) tests were performed on the bulk samples obtained from ' borings T-10 and T-13, each mixed with 3 percent Quicklime.

The samples were then soaked for 96 hours during which swell values ranging from 0.1 percent for the highly plastic clay sample (4.5% without lime) to 0.3 percent for the highly plastic silt sample (4.2% without lime) were recorded. After soaking, CBR values ranging from 31 percent for the highly plastic silt sample (1.9% without lime) to 37 percent for the highly plastic clay sample (1.3% without lime) were recorded.

CONCLUSIONS AND RECOMMENDATIONS The subsur ace exploration indicates that tilt site is adapta'oie for the proposed construction. The primary geotechnical concerns at this site consist of the following: • Shallow groundwater tables will be encountered near and above proposed final grades, predominantly in the infield and drainage swale areas where the deeper cuts will occur. . • Natural moisture contents of on-site soils are significantly above their optimum moisture contents. • Highly plastic soils (clays and silts) will be encountered at or near final grades in cut areas. • Highly plastic soils will be required for use as structural fill in pavement and building areas since they are estimated to comprise over half of the soils at this site. The above issues will require specialized construction measures during grading. Such measures will include: • Some site dewatering (lowering of groundwater) before and during grading activities and permanent below-ground drainage (blanket, edge and French drains) in some pavement and infield areas. • Using specialized construction equipment in excavation areas where groundwater levels are near or above final grades. Use of track backhoes working above the groundwater table, top loading all terrain dump trucks, will be required to excavate to final grades. • Drying of on-site soils prior to their use as structural fill by means of significant scarifying and aerating or adding quicklime where very wet soils are encountered and compaction cannot be achieved. • Lime stabilizing of soils. at design grades in pavement and building areas using experienced contractors with specialized equipment for spreading, mixing, moisture conditioning, compacting and curing of the lime treated soil. • Allowing settlement due to mass fill loading to stabilize prior to paving. This will require installation of settlement plates and surface survey hubs to monitor fill settlements. Site grading will be very difficult during periods of extended rainfall and low ' temperatures that generally occur during the winter months. The clayey and silty soils at this site are very moisture sensitive. When wet, these soils tend to rut a11d pump under rubber-tired traffic and provide poor subgrade support for pavements, foundations, and floor slabs. Grading during wet weather will create significant undercutting and wasting of soils which can be substantially reduced if grading is undertaken during more favorable weather. 10 1 1 1 1 1 Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR -Northampton County NC April 15, 2008 To reduce potential earthwork problems, site preparation and grading should be scheduled during the typically drier late spring; summer and early fall months; if poss;ble. Heavy rubber-tired construction equipment should not be allowed to operate on very wet or highly unstable subgrades at this site due to the potential for severe rutting and other damage fo the soils. Panning and trucking operations should not concentrate their hauling operations along the same routes. Their routes should be spread across the fill and cut areas. No heavy rubber tired equipment should be allowed to operate on soils found below the groundwater table. We recommend that exposed subgrades be sloped and sealed at the end of each day to promote runoff and reduce infiltration from rainfall. Proposed grades along the entrance road and in building areas were unknown at the time of this report. We recommend that at least 3 feet of vertical separation be provided between groundwater levels and final grades in these areas. The following sections present more detailed conclusions and recommendations regarding site development. Please note that areas outside of the proposed Phase I development have not been explored. Conditions in these areas maybe different than those presented in this report. Areas outside of the proposed Phase I development that will receive excess fill should be evaluated by a representative of the geotechnical engineer prior to fill placement. 6.1 Site Preparation 6.1.1 Clearing, Grubbing, Stripping of Topsoil Site preparation should begin by clearing trees, grubbing stumps, and removing vegetation and other unsuitable surface material from proposed construction areas. A large amount of downed trees and low cut stumps are still present in the previously harvested areas. The contractor should be prepared to dispose of these materials along with trees, stumps and vegetation in wooded areas. Topsoil depths ranging from 4 to 18 inches were encountered in the borings and test pits. Typical topsoil depths range between 6 and 12 inches. Deeper stripping depths should be anticipated during wet conditions and in portions of the site that were rutted during past clearing operations. Clearing and stripping operations over marginally stable subgrades will disturb underlying "clean" soils causing stripping depths to be greater than actual topsoil depths. Stripping should be performed with light, wide tracked equipment to reduce disturbance of underlying soils. Heavy rubber-tired trucks, loaders or pans should not be allowed to operate on marginally stable soils because rutting and pumping will likely occur, requiring repair of these areas. The effects of using heavy rubber-tired equipment during 11 Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR -Northampton County NC April 15, 2008 ' clearing are apparent in the harvested areas where ruts containing ponded water currently exist. Topsoil maybe re-used on the surface of slopes for landscaping and in other areas approved by the civil engineer. Topsoil amounts greater than those required for ' landscaping should be anticipated and disposed of in designated areas. ' 6.1.2 Temporary Site and Subsurface Drainage A drainage feature (swale) currently exists on the northwest portion of the site. We recommend that a temporary ditch be constructed in this area to handle surface runoff during initial grading operations. The depth and width of the ditch necessary to handle ' surface runoff should be determined by the contractor during initial grading. The ditch should slope to drain to the west and if no outlet is available a sump and pumping operation maybe required. ' i ll i h i a y n t e areas ons, espec Control of groundwater will be required during grading operat where cuts will extend at or below the groundwater table (i.e. borings T-5, T-7, T-17, T- ' 18, T-19, and T-29). Groundwater should be maintained at least 2 feet below final grades. Temporary ditching, digging of sumps, and pumping will likely be required to maintain this separation. The final grading plans call for drainage swales or ditches in the cut areas of the infield. Early excavation of these drainage features will expedite subsurface drainage and help lower water tables. The contractor should be responsible for determining groundwater control measures during grading. 6.1.3 Evaluation of Areas to Receive Fill ' ce the ~te is stri ed of unsuitable surface materials and tem or draina e has been On si pp p ary g installed, the exposed subgrade of areas to receive fill should be evaluated by the ' geotechnical engineer. To aid the engineer during this evaluation, exposed subgrades should be proofrolled wrth a partially loaded dump truck or partially loaded pan. Any areas that are observed to rut, pump, or deflect excessively during the proofrolling ' process should be repaired as recommended by the geotechnical engineer. Possible repair measures could include undercutting and replacement or in place repair by drying and recompaction. Undercutting and replacement with compacted fill maybe considered in ' areas where at least 2 feet of separation exist between groundwater levels and undercut elevations. Bridge lifts maybe considered in pavement or infield areas where at least 5 feet of fill will be required to reach design grades. No bridge lifts will be allowed in ' building areas. The most practical repair measure will be influenced by the degree of instability which exists and prevailing weather conditions. As such, actual repair ' measures must be determined in the field at time of construction. ' 12 ' Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR -Northampton County NC April 15, 2008 6.2 Excavations ' xcavat. n b ve and l,c>1 ~z~ rl 4 1 '71 1. .1 !l ,1 ~~ E o s a o ~~u .,,,~o~. grounuvJawr levels vv'iu ve requireu. vur recoriuiteilua~1G11S for excavations are presented below. ' For confined excavations, trench safety must be evaluated on a case-by-case basis. The contractor will be responsible for all site safety, including the determination of appropriate trench safety measures according to OSHA guidelines. Excavation shoring or ' slope inclinations should properly account for hydrostatic pressures and seepage. The contractor should have extensive experience excavating in soils below the groundwater. 6.2.1 Excavations Above Groundwater Levels ' Excavations at least 2 feet above groundwater levels will typically extend through moderate to high consistency natural soils predominantly consisting of clays and silts. ' Past experience indicates that these materials can be excavated using conventional earth- moving equipment including dozers, pans, scrapers, and excavators. Local excavations for shallow utility trenches and foundations can likely be accomplished by a conventional ' backhoe. ' 6.2.2 Excavations Near and Below Groundwater Levels Groundwater levels were encountered above and within 2 feet of final grades in borings T-5, T-7, T-17, T-18, T-19, and T-29. Excavations within 2 feet and below groundwater levels will extend through moderate to high consistency natural soils consisting of clays, silts and sands. We recommend that as groundwater levels are approached that ' specialized equipment such as wide track dozers, all terrain dump trucks, track excavators, etc., be used to excavate these materials. The excavatlons below the groundwater table should be accomplished by a track backhoe with smooth face bucket, ' top loading all terrain dump trucks. No construction equipment should be allowed on the final grades in these areas. If pans are able to operate below the water table in the firm to stiff clays, their operations should cease at least 2 feet above the final grades and these ' final soils removed by backhoes top loading all terrain dump trucks. No construction equipment should be allowed to disturb the soils at the final grades. Groundwater infiltration will occur in excavations extending below groundwater levels. Groundwater infiltration will reduce stability of excavation slopes and will soften subgrades within excavation bottoms. The contractor should be prepared to install ' adequate drainage measures such as French drains, open ditches, internal sumps and pumps to keep groundwater at least 2 feet below final excavation grades. The final grading plans call for drainage swales or ditches in the cut areas of the infield. Early 13 1 1 Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR -Northampton County NC April 15, 2008 excavation of these drainage features will expedite subsurface drainage and help lower water tables In proposed pavement areas, we recommend a blanket underdrain be installed beneath the pavement section where the bottoms of pavement excavations are within 2 feet of and below current groundwater levels. Soiree portions of the ride and handling road will require a blanket underdrain. Potential road sections requiring an underdrain could be near borings T-5, T-7, T-17, T-18, T-19 and T-29 where groundwater levels were within 2 feet of pavement bottom. The actual road sections requiring the underdrain will have to be identified in the field by an experienced geotechnical engineer. The underdrain should consist of 10 inches of washed stone (NCDOT #57) encapsulated (bottom, sides and top) with a needle punched nonwoven geotextile. The geotextile should be placed by hand labor and the NCDOT #57 stone should be end dumped from the trucks and pushed out on to the geotextile with wide track dozers. No equipment should be allowed on the geotextile. All stone trucks should operate on the stone layer. Edge drains should be included as part of the underdrain and should slope to drain to the open ditch beyond the runout area. See Figure 3C in the Appendix. In the infield where the cuts extend below the groundwater table a longitudinal French drain may be needed in this area for dewatering. This drain should be connected to the open ditch. 6.3 Structural Fill 6.3.1 Re-Use of On-Site Soils as Structural Fill On-site soils, excluding topsoil and soils with less than 3 percent organics, maybe used as fill in the pavement, infield and building areas provided recommendations provided herein are followed. Our experience has shown when borrowing soils from areas that were in the past covered with pines, the tap roots may extend several feet below the ground surface. Wasting of borrow soils (below the stripped topsoil) with these tap roots is not necessary; however, if excessive tap roots are prevalent in the fill sections, some root raking maybe necessary. The need to remove some of the roots in the fill section will need to be determined in the field by a representative of the geotechnical engineer. On-site soils consist of high plasticity silts and clays (MH, CH) along with low plasticity sands, silts, and clays (SM, SC, SP-SC, ML, CL). It should be expected that over 1/2 of the on-site borrow will consist of high plasticity clays and silts. Based on laboratory testing, high and low plasticity soils are 2 to 16 percent wet of their optimum moisture ' content. The wetter soils were those sampled below the water table; however, even those soils above the water table had natural moistures 4 to 10 percent above their OMC. The average of the moisture contents relative to their OMC for all tested samples was 6 1 14 Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR -Northampton County, NC April 15, 2008 ' percent wet with a similar average wet of OMC value for the plastic clays and silts. Reduction of the natural moisture contents will be paramount for the successful grading ' and compaction of soils at this site. ' In our opinion this natural drying can only be accomplished during warm and low humidity weather conditions that can exist during the late spring, summer and early fall. This drying will require the grading contractor to extensively disc, harrow, windrow, aerate, etc. during favorable weather conditions. Soils should not be considered unsuitable due to moisture content. For those soils having natural moistures greater than 6 percent wet of their OMC it may become more cost effective and efficient to add (rotary mix) 1 to 2 percent quicklime into the cut soils prior to excavating and placing in the fill section. This amount of lime addition should sufficiently dry the soils to allow the required compaction to be obtained. The compaction moisture requirements for this project will allow the grading contractor to place the fill at OMC to 3 percent wet of OMC for areas requiring 95 percent of the standard Proctor maximum dry density and OMC to 5 percent wet of OMC for areas requiring 92 percent compaction (see Section 6.3.2 Fill Placement). Therefore, the drying of the borrow soils will not be as extensive as would normally be required and should allow the grading contractor to achieve most of the drying without resorting to lime addition. The need for lime for drying will be a function of weather, wetness of the soil and time saved not drying by natural means. 6.3.2 Fill Placement All structural fill should be placed in 8 to 10 inch loose lifts. The geotechnical engineer or a qualified soil technician working under the direction of the geotechnical engineer should observe site preparation and fill placement operations. A sufficient number of density tests and moisture checks should be performed during fill placement to confirm that the recommended degree of compaction and moisture ranges are being achieved. Recommendations for each of the proposed areas are provided in the following sections. Pavement Areas ' Pavement areas include those areas beneath the pavement and extending out 10 feet on either side. In these areas structural fill should be compacted to at least 95 percent of the standard Proctor maximum dry density (ASTM D 698). In order to achieve 95 percent compaction and obtain a moisture range that reduces future swell potential of the plastic soils, the borrow soils will need to be placed in a moisture range of OMC to 3 percent wet of OMC. 15 Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR Northampton County NC April 15, 2008 We recommend that the final 12 inches in pavement areas consist of soils stabilized using 4 percent quicklime by dry weight. This stabilized zone should extend 5 feet ol~tsi_de the pavement box on both sides. See Figure 3A in the Appendix. Recommendations regarding lime stabilization are presented in section 6.4.2 of this report. Lime treated soils should be compacted to 98 percent of their lime treated standard Proctor maximum dry density and in a moisture range of OMC to 3 percent wet of OMC. Sufficient moisture should be present in the soils to activate (hydrate) the lime. Literature and experience suggests this will likely require the moistures to be closer to the 3 percent wet of OMC. Lime treatment of the top 12 inches of subgrade will also be required in the cut areas where groundwater tables are 2 feet or greater below the bottom of the pavement section. See Figure 3B in the Appendix. Fill placed in the road shoulder areas (10 feet outside the pavement edges) should be compacted to at least 95 percent of the soil's standard Proctor maximum dry density in a moisture range of OMC to 3 percent wet of OMC. These soils should consist of the clayey soils having maximum plasticity indices (PIs) of 35 percent. The reason for placing clayey soils in the road shoulder is to reduce moisture penetration beside the pavement section and into the subgrade soils. We understand the shoulder grades are set at 2 percent. This slope is necessary to provide positive runoff. Ponding of surface water on the shoulder would be detrimental to the life and serviceability of the asphalt pavement. We understand the shoulders will be grassed. As the turf is established the shoulders should be mowed and maintained so water freely flows off the pavement and shoulder in to the infield area. Infield Areas Structural fill placed in the infield areas should be compacted to at least 92 percent of the standard Proctor maximum dry density (ASTM D 698) with exception of the final foot which should receive 95 percent compaction. In order to achieve 92 percent compaction, the moisture content of these fill soils will need to be reduced to no greater than 5 percent wet of their OMC. At these moisture levels the fill sections will most likely be unstable and some rutting may occur under heavy rubber tired equipment. If trafficabilty issues develop, the contractor may have to perform some additional soil drying or use lighter ground contact pressure equipment. In order to achieve 95 percent compaction, the moisture content of these fill soils will need to be reduced to at least 3 percent wet of the soil's OMC. Building Areas From a fill placement standpoint the building areas should include the building pad footprint and an area extending 10 feet beyond the footprint. On-site soils maybe used as structural fill in the proposed building areas. The final 12 inches at the subgrade level 16 Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR -Northampton County NC April 15, 2008 L should be stabilized with 4 percent lime by weight (see section 6.4.1) to reduce the soil's plasticity and increase slab subgrade support. Fill soils placed below the final 12 inches in the building areas should be compacted to at least 95 percent of their standard Proctor maximum dry density (ASTM D 698). The ' moisture content of these fill soils should be maintained between OMC and 3 percent wet of their OMC during compaction to reduce future swelling potential. Lime stabilized soils placed in the final 12 inches below final grade in building areas should be compacted to 98 percent of their lime treated standard Proctor maximum dry density (ASTM D 698). The moisture content of these fill soils should be in a range of OMC to 3 percent wet of OMC. Sufficient moisture should be present in the soils to activate (hydrate) the lime which will most likely require the moistures to be closer to the 3 percent wet of OMC. 6.3.3 Settlement Due to Fill d way We anticipate as much as 7 feet of fill will be required at this site for roa construction. The weight of this fill will cause underlying soils to settle and some consolidation of the fill mass will occur. A consolidation test was performed on an undisturbed sample of the more compressible virgin soils. Two consolidation tests were also performed on recompacted samples of the highly plastic soils. These samples were recompacted at 92 percent and 95 percent of their standard Proctor maximum dry density at moistures on the wet side of the Proctor curves. These tests indicate C~ values of 0.03 to 0.06 and C,, values of 3.6 to 3.8 feet squared per day. Utilizing this test data and fill loads of 10 feet, maximum settlement of about 2 inches was calculated. Also, based on time-rate consolidation analysis we have estimated 90 percent or more of the settlement will occur within 1 to 4 weeks after. completion of fill placement. Therefore, based on this analysis it would appear pavement construction could begin 3 to 4 weeks after the completion of fill placement. It is estimated that after this waiting period the roadway in deeper fill sections should experience less tan %2 inch of future settlement. In order to monitor the fill settlement in pavement and building areas where more than 5 feet of fill is placed, we recommend that settlement plates be installed at the base of the fill. Once these areas have been raised to design subgrade elevation, settlement hubs should be installed at the surface. The elevation of the plates and hubs should be measured at least twice weekly by the surveyor. This data should be furnished to us for review. Asphalt paving operations and foundation construction should not begin in these areas until monitoring of settlement hubs indicates that fill induced settlement has stabilized. 17 Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR Northampton County NC April 15, 2008 6.4 Lime Amendment The. limp amenr~rnent pros a:Il «~~ll .^.Cns.St of uuing iiiiie jvr Stauiiizaiivri grid diyirtg purposes. Lime amendment will be required to stabilize subgrade soils in the building and pavement areas (cut and fill sections) and may also be needed for drying some of the soils that have excessive moisture contents to obtain the recommended degree of compaction. Construction considerations regarding both lime stabilization and drying are described in the following sections. It should be noted that quicklime is an alkaline material that is reactive in the presence of moisture. Construction workers should be made aware of the hazards associated with lime including (but not limited to) eye irritation, skin burns (both chemical and thermal}, and inhalation hazards. 6.4.1 Drying Due to the relatively high natural moisture contents of some of the on-site soils, quicklime may be required in areas requiring 95 percent compaction to expedite fill placement by lowering in-situ moistures and causing some slight improvement in the soil plasticity characteristics. We recommend lime only be used for drying soils with moisture ' r s OMC. contents greater than 6 percent of the soil Lime for drying will typically require mixing 1 to 2 percent lime by dry weight into the soils. With the addition of quicklime, the moisture content of the soils is reduced by the following processes: • Chemical combination of water and lime evaporates water • Heat from the reaction increases evaporation ' • Chemical changes in the soil reduce its capacity to hold water The lime drying process typically consists of the following steps: fill areas th b i il l . orrow or e ayer n 1. Scarifying so 2. Spreading of lime at a rate determined by the lime contractor in the field at time of grading. 3. Rotor mixing the lime into the soil. 4. Allowing sufficient time for the lime to react with the soils for drying to occur. 5. Removal of the lime treated layer from the cut area and transport to the fill section for placement and compaction or compaction of the lime Treated Layer in the fill section. ill b h d e s w o The amount of quicklime required to dry the soils and construction met dependent upon conditions encountered during construction and should be determined by 18 1 1 1 1 Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR Northampton County NC April 15. 2008 a qualified contractor experienced with lime modification. Lime modification. should not be performed on frozen soil. 6.4.2 Stabilization Due to low California Bearing Ratio (CBR) values and the tendency of highly plastic soils to shrink/swell with changes in moisture content, we recommend that the final 12 inches of subgrade in both cuts and fills of pavement and building pad areas be lime stabilized. Lime stabilization, if constructed properly, provides long-term strength, stability and durability, while also producing a relatively impermeable layer. Based on laboratory testing, we recommend 4 percent lime by dry weight be incorporated into the upper 12 inches of subgrade within the building and pavement limits and 5 feet beyond those limits. The lime stabilization construction process typically consists of the following steps: 1. Bringing soil layer to desired grade. 2. Scarifying soil layer and partial pulverization. 3. Spreading of quicklime at a rate of at least 4 percent by dry weight. 4. Rotor mixing of lime with soil while hydrating the lime. 5. Allowing soil to mellow for a sufficient period to allow the chemical reaction to occur. 6. Further rotor mixing and pulverizing lime amended soil to achieve thorough mixing. Obtaining proper moisture in the soils for compaction. 7. Compacting soil/lime mixture to desired compaction level. 8. Curing of soil by sealing the compacted layer with a bituminous prime coat emulsion. Lime stabilization methods should be performed in general accordance with the 2006 North Carolina Department of Transportation (NCDOT) "Standard Specifications for Roads and Structures", Section 501. Lime stabilization should not be performed when the air temperature is below 45 degrees Fahrenheit. Lime should only be applied in areas that can be initially mixed and sealed during the day of application. Lime should not be applied in windy conditions. We recommend that a representative of the geotechnical engineer be on-site during lime stabilization to confirm the following items are in accordance with our recommendations: • Amount of lime spread • Lime hydration is consistent throughout treated layer Thickness of lime stabilized layer 1 19 Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR -Northampton County, NC April 15, 2008 ' Compaction of lime stabilized layer 6.5 Permanent Cut and Fill Slopes ' Permanent cut and fill slopes should be constructed at least 3:1 (H:V) or flatter for long- term stability and erosion control. Based on the final grading plan, proposed cut and fill slopes are designed with an inclination of 4:1 (H:V). Slopes should be vegetated as soon as possible to reduce surface erosion. Slopes of 3:1 (H:V) or flatter are typically required to allow mowers and other landscaping equipment to operate safely. Buildings or ' structures should be located a sufficient distance (at least 10 feet) from the edge of crest of any slope to avoid creating slope instability due to the surcharge loading. 6.6 Subgrade Repair and Improvement Methods Exposed untreated subgrades can deteriorate and lose support when exposed to construction traffic and adverse weather conditions. Deterioration can occur in the form or rutting, pumping, freezing, or erosion. We recommend that during construction, exposed Subgrade surfaces be sealed and sloped to drain at the end of each day or when wet weather is forecast. 6.7 Pavement Design Recommendations We understand the ride and handling road will consist of mostly asphalt pavement with some sections being considered for concrete pavement. We understand that the entrance road will consist of asphalt pavement. Our pavement design recommendations are based on the assumed traffic loading conditions, our field and laboratory findings and analysis using AASHTO Guide for Design of Pavement Structures (1993) design procedures. Our recommendations for asphalt and concrete pavement are provided in the following sections. 6.7.1 Flexible (Asphalt) Pavement ' The flexible avement should consist of a surface course of as haltic concrete underlain p p by crushed aggregate base course (CABC) stone underlain by 12 inches of lime stabilized subbase. The pavement section presented below is based on a design California Bearing Ratio (CBR) value of 2 percent for the clayey and silty subgrade soils. ' 20 Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR -Northampton County NC April 15, 2008 Flexible Pavement Flexible Pavement NCCAR Design (inches) Design (inches) Asphalt Pavement Ride and Handling Road Entrance Road Asphalt Concrete Surface Course - 1.5 2.0 Superpave Type S-9.SB Asphalt Concrete Intermediate Course - 2.5 3.0 Superpave Type I-19.OB Crushed Aggregate Base Course (CABC) 8.0 10.0 Stone Lime Stabilized Subbase 12.0 12.0 All materials and construction methods should conform to the 2006 edition of the NCDOT "Standard Specifications for Roads and Structures. " Recommendations regarding lime stabilization of the subbase are described in section 6.4.2 of this report. The crushed aggregate base course stone should consist of stone meeting the requirements under Section 520, pages 5-10 through 5-15 and Section 1010, pages 10-30 through 10-40. The base course stone should be compacted to at least 100 percent of the maximum dry density as determined by the modified Proctor compaction test, AASHTO T-180 as modified by NCDOT. To confirm that the base course stone has been uniformly compacted and has sufficient thickness, in-place density tests and thickness measurements should be performed by a qualified soils technician and the area should be thoroughly proofrolled under his observation. The base course stone should be end dumped from the trucks and pushed out onto the lime treated subgrade. The stone trucks should not be allowed to operate directly on the lime treated subgrade soils. The asphaltic concrete should consist of Superpave types S-9.SB and I-19.OB. Asphaltic concrete should conform to Section 610, pages 6-27 through 6-51 in the 2006 edition of the NCDOT "Standard Specifications for Roads and Structures. " A tack coat should be placed between the surface and intermediate asphalt courses. Sufficient testing and observation should be performed during pavement construction to confirm. that the required thickness, density, and quality requirements of the specifications are obtained. r 21 Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR -Northampton County NC April 15, 2008 Although our analysis was based on a 20 year design life, our experience indicates that an overlay may be needed in approximately 12 to 15 years due to normal weathering and aging of the asphaltic concrete. Also, some areas could require repair in a shorter time period. 6.7.2 Rigid (Concrete) Pavement Concrete pavement sections should consist of the section presented in the table below. Our concrete pavement design was performed using the same design traffic as in asphalt pavement areas along the ride and handling track (100,000 ESALs). The compressive strength of the concrete was assumed to be 4,000 psi. A modulus of subgrade reaction of ' 175 pci was used for design assuming 6 inches of compacted CABC stone underlain by 12 inches of lime treated soils beneath the pavement. We have assumed that load transfer across contraction (saw} joints will be handled by aggregate interlock. At construction or expansion joints load transfer devices such as smooth steel dowels should be considered. CABC should meet the material and compaction requirements stated in the "Flexible (Asphalt) Pavement" section above. 1 1 NCCAR Concrete Pavement Concrete Pavement Design Ride and Handling Road Concrete (4,000 psi) 6.0 inches Crushed Aggregate Base Course (CABC} Stone 6.0 inches Lime Stabilized Subbase 12.0 inches Maximum Joint Spacing 15 feet in all directions Saw joints should be cut at least'/4 of the thickness of the concrete pavement to promote shrinkage cracking along the joint. 6.8 Foundation Support 6.8.1 General The proposed security kiosk and operations and administration building maybe supported on shallow spread footings bearing in the virgin soils or compacted fill. The shallow spread footings maybe designed with an allowable soil bearing pressure of 3,000 pounds per square foot. In order to help maintain moisture conditions in the soils beneath the slab and reduce the potential for shrink/swell issues in the plastic soils, we recommend 22 Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR -Northampton County NC April 15, 2008 ' that a curtain wall footing be installed around the perimeter of the buildings. This footing should bear at a level 30 inches below exterior grade and can be used to support any exterior building wall loads. We also recommend interior column and wall footings bear 30 inches below subgrade elevations. These bearing elevations will provide adequate frost protection. Individual column footings should be at least 24 inches wide and continuous wall footings should be at least 18 inches wide. This recommendation is made to help prevent localized or "punching" shear failure which can occur with very narrow footings. The geotechnical engineer or his representative should observe foundation bearing conditions prior to placement of reinforcing steel and concrete. This evaluation should include the performance of shallow hand auger borings with dynamic cone penetrometer testing to confirm the suitability of bearing soils for foundation support. Exposure to the environment will cause the bearing soils to rapidly deteriorate, particularly if foundations extend near or below groundwater. Excessively loose/soft soils, water and other unsuitable materials should be removed. Over-excavated soils should be replaced with lean concrete. If foundations extend near or below groundwater, a lean concrete mud mat should be placed above the exposed subgrade to reduce groundwater infiltration and loosening/softening of bearing soils. A mud mat will also provide a firm surface for placement of reinforcing steel. To further reduce the potential for deterioration of bearing soils, we recommend that foundation excavation and placement of concrete be conducted on the same day if practical. ' 6.8.2 Settlement Based on encountered subsurface conditions, anticipated loads, and assuming the site is prepared in accordance with this report, we expect that total settlement beneath shallow foundations should be 1 inch or less. Detailed structural information is necessary to ' estimate differential settlement. However, we expect that differential settlements will be less than 1/2 inch for footings bearing on similar materials. 6.9 Floor Slabs The floor slabs can be adequately supported on lime stabilized soils. We recommend that the upper 12 inches beneath buildings be lime stabilized in accordance with the recommendations provided in this report (section 6.4.2). We recommend a subgrade modulus of 150 pci be used for lime stabilized soil supported slabs with maximum distributed loads of less than 100 pounds per square foot (psf) or relatively light concentrated loads. If slabs will support larger distributed loads or relatively high concentrated loads, this information should be provided to us for review. t 23 Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR -Northampton County NC April 15, 2008 The slab should be separated from column and wall footings to allow for relative displacement. This separation is especially important along the wall footing (curtain wall). If the slab is structurally attached to the wall footing, cracking could occur in this area. This would be due to the slab being restrained by the lug footing, not allowing the slab to shrink (drag) along the subgrade. Once tension stresses in the slab exceed the concrete's tensile strength a crack would occur. Exposure to the environment and construction activities will weaken the floor slab subgrade soils. Therefore, we recommend that subgrade soils in slab areas be evaluated prior to concrete placement. If deterioration of soils has occurred, undercutting and replacement maybe necessary. 6.10 Seismic Site Classification Based on results of soil test borings, past experience, and information provided in section 1615 of the North Carolina Building Code, it is our opinion the site should preliminarily be considered as Class D with respect to seismic design considerations. 7. QUALITY CONTROL MONITORING AND TESTING The subsurface conditions at this site warrant the presence of full-time, on-site, experienced soil technicians working under the direction of the geotechnical engineer. We recommend that our fine be utilized to provide these services because of our familiarity with the project design assumptions, site and subsurface conditions and our engineering analysis which form the basis for the recommendations presented herein. Construction items that will require field monitoring and testing will include but are not limited to: • Proofrolling of subgrades to evaluate stability and strength • Monitoring of drainage and dewatering activities • Density and moisture testing of borrow soils • Field classification of soils • Monitoring and testing during lime amendment operations • Footing bearing evaluations • Evaluation of fill settlement data 8. QUALIFICATIONS OF REPORT This report has been prepared in accordance with generally accepted engineering practice for specific application to this project. Any wetland, environmental, or contaminant assessment efforts are beyond the scope of this geotechnical exploration; and therefore, those issues are not addressed in this geotechnical exploration report. The recommendations contained in this report are based on the applicable standards of our 24 Subsurface Exploration Report S&ME Project No. 1051-07-460 NCCAR -Northampton County, NC April 15, 2008 profession at the time this report was prepared. No other warranty, express or implied, is made. Conclusions and recommendations submitted in this report are based, in part, upon the data obtained from the geotechnical exploration. The nature and extent of variations between and outside of the borings made may not become evident until construction. If variations appear evident, then it will be necessary to re-evaluate the recommendations of this report. In the event that any changes in the grades, nature, design, or location of the proposed structures or pavements are planned, the recommendations contained in this report should be reviewed and modified or verified in writing. We recommend that our firm be provided the opportunity for general review of final design specifications to verify that recommendations are properly interpreted and implemented. 1 25 L /J iV lV V t ~. ~, '' i ~.
