However, the use of fine-grained soils can result in poor internal and surface drainage, as well as time dependent movements of the MSE Wall and related components. If fine grained low plasticity soils are used for MSE Wall backfill, we recommend additional internal drainage such as a chimney drain should be incorporated into the final wall design. The preceding paragraphs and tables are intended to provide a general overview of the design and construction of the MSE Walls. Specific guidance regarding the design and construction of MSE Walls can be found in the current edition of the NCMA Design Manual for Segmental Retaining Walls. The information provided above does not alleviate the MSE Wall designer from any aspect of the design including selection of shear strength parameters, internal wall stability, external wall stability, global stability or settlement estimates. 5.11. Reuse of On-site Cut Soils The existing on-site soils are generally acceptable for re -use across the site. However, Borings B-21, B-22, B-23, P-46, P-47, and P-48 have MH soils in proposed cut areas as shown in the Boring Location Diagram (Figure 2) located in the Appendix. Laboratory test results indicate that the natural moisture content of anticipated cut materials may vary between 24.3 and 31.7 percent. The natural moisture contents are anticipated to be near optimum moisture content; however, moisture conditioning of on-site soils may be required. ECS can provide further recommendations for moisture conditioning of the on-site soils upon request. Soils with USCS group symbol of MH may be used in deeper fills (greater than 4 ft) with the additional requirement that they remain stable beneath heavy construction traffic. The sequencing during the grading of the site should be taken into consideration in order to place the MH soils in the deeper fill areas. 5.12. Deep Fills & Settlement Monitoring ECS anticipates that fills of up to 29 feet will be required at the site. ECS recommends that settlement hubs be placed within areas receiving more than 15 feet of fill to monitor consolidation of the fill and residual materials. The frequency of monitoring should be on a weekly basis, but this should be adjusted as necessary by the geotechnical engineer based upon fill placement rates and settlement rates. Typically, the settlement rates will accelerate during the fill placement, and start tapering off shortly after stopping any fill placement. ECS recommends a minimum timeline between 45 and 60 days to monitor the consolidation upon completion of fill placement. Upon reaching a tolerable settlement rate, foundation construction may begin. Alternatively, compaction requirements may be increased in order to reduce the consolidation time during construction. Report of Subsurface Exploration Afton Ridge Industrial Concord, North Carolina Page 15 CONSTRUCTION CONSIDERATIONS 6.1. Site Preparation Mr. Jon Wilson Childress Klein Properties ECS Project No. 08-10919 June 26, 2015 Prior to construction, the proposed construction area should be stripped of all topsoil, organic material, construction debris, existing undocumented fill within the building footprint, and other soft or unsuitable material. Upon completion of these razing and stripping operations, the exposed subgrade in areas to receive fill should be proofrolled with a loaded dump truck or similar pneumatic -tired vehicle having a loaded weight of approximately 25 tons. After excavation, the exposed subgrades in cut areas should be similarly proofrolled. Proofrolling operations should be performed under the observation of a geotechnical engineer or his authorized representative. The proofrolling should consist of two (2) complete passes of the exposed areas, with each pass being in a direction perpendicular to the preceding one. Any areas which deflect, rut or pump during the proofrolling, and fail to be remedied with successive passes, should be undercut to suitable soils and backfilled with compacted fill. The ability to dry wet soils, and therefore the ability to use them for fill, will likely be enhanced if earthwork is performed during summer or early fall If earthwork is performed during winter or after appreciable rainfall then subgrades may be unstable due to wet soil conditions, which could increase the amount of undercutting required. Drying of wet soils, if encountered, may be accomplished by spreading and disking or by other mechanical or chemical means. 6.2. Fill Material and Placement The project fill should be soil that has less than five percent organic content and a liquid limit and plasticity index less than 50 and 30, respectively Soils with Unified Soil Classification System group symbols of SP, SW, SM, SC, and ML are generally suitable for use as project fill. Soils with USCS group symbol of CL that meet the restrictions for liquid limit and plasticity index are also suitable for use as project fill. Soils with USCS group symbol of MH may be used in deeper fills (greater than 4 ft) with the additional requirement that they remain stable beneath heavy construction traffic. Soils with USCS group symbol of CH (high plasticity soil) or corrosive soils are generally not suitable for use as project fill. Based on the results of the test pit observations, it appears that the soils within the' existing landfill should not be considered suitable for reuse in their present condition. If desired, sorting and screening may be utilized to remove the organics and other debris. If the organics and debris are removed from within the existing stockpile soils, the soils appear suitable for reuse. The fill should exhibit a maximum dry density of at least 90 pounds per cubic foot, as determined by a standard Proctor compaction test (ASTM D-698). We recommend that moisture control limits of -3 to +2 percent of the optimum moisture content be used for placement of project fill with the added requirement that fill soils placed wet of optimum remain stable under heavy pneumatic -tired construction traffic. During site grading, some moisture modification (drying and/or wetting) of the onsite soils will likely be required. Project fill should be compacted to at least 95 percent of its standard Proctor maximum dry density except within 24 inches of finished soil subgrade elevation beneath slab -on -grade and pavements. Within the top 24 inches of finished soil subgrade elevation beneath slab on grade and pavements, the approved project fill should be compacted to at least 100 percent of its standard Proctor maximum dry density. Aggregate base course (ABC stone) should be compacted to 100 percent of standard Proctor maximum dry density. However, for isolated Report of Subsurface Exploration Afton Ridge Industrial Concord, North Carolina Page 16 Mr. Jon Wilson Childress Klein Properties ECS Project No. 08-10919 June 26, 2015 excavations around footing locations or within utility excavations, a hand tamper will likely be required. ECS recommends that field density tests be performed on the fill as it is being placed, - at a frequency determined by an experienced geotechnical engineer, to verify that proper compaction is achieved. The maximum loose lift thickness depends upon the type of compaction equipment used. The table below provides maximum loose lifts that may be placed based on compaction equipment. LIFT THICKNESS RECOMMENDATIONS Equipment Maximum Loose Lift Thickness, in. Large, Self -Propelled Equipment (CAT 815, etc.) 8 Small, Self -Propelled or Remote Controlled Rammax, etc. 6 Hand Operated (Plate Tamps, Jumping Jacks, Wacker- 4 Packers ECS recommends that fill operations be observed and tested by an engineering technician to determine if compaction requirements are being met. The testing agency should perform a sufficient number of tests to confirm that compaction is being achieved. For mass grading operations we recommend a minimum of one density test per 2,500 SF per lift of fill placed or per 1 foot of fill thickness, whichever results in more tests. When dry, the majority of the site soil should provide adequate subgrade support for fill placement and construction operations. When wet, the soil may degrade quickly with disturbance from construction traffic. Good site drainage should be maintained during earthwork operations to prevent ponding water on exposed subgrades. We recommend at least one test per 1 foot thickness of fill for every 100 linear ft of utility trench backfill. Where fill will be placed on existing slopes, we recommend that benches be cut in the existing slope to accept the new fill. All fill slopes should be overbuilt and then cut back to expose compacted material on the slope face. While compacting adjacent to below -grade walls, heavy construction equipment should maintain a horizontal distance of 1(H):1(V). If this minimum distance cannot be maintained, the compaction equipment should run perpendicular, not parallel to, the long axis of the wall. 6.3. Foundation Construction & Testing Foundation excavations should be tested to confirm adequate bearing prior to installation of reinforcing steel or placement of concrete. Unsuitable soils should be undercut to firm soils and the undercut excavations should be backfilled with compacted controlled fill. Exposure to the environment may weaken the soils at the footing bearing level if the foundation excavations remain open for too long a time; therefore, foundation concrete should be placed the same day that foundations are excavated. If the bearing soils are softened by surface water intrusion or exposure, the softened soils must be removed from the foundation excavation bottom immediately prior to placement of concrete. If the excavation must remain open overnight, or if rainfall becomes imminent while the bearing soils are exposed, a 1- to 3 -inch thick "mud mat" of "lean" concrete may be placed on the bearing surface to protect the bearing soils. The mud mat should not be placed until the bearing soils have been tested for adequate bearing capacity. Foundations undercut should be backfilled with engineered fill. If lean concrete is placed within the undercut zone, the foundation footprint does not require oversizing. However, if soil or ABC stone is used in lieu of lean concrete, the foundation footprint should be oversized on a 1V:1H scale. Report of Subsurface Exploration Afton Ridge Industrial Concord, North Carolina Page 17 Mr. Jon Wilson Childress Klein Properties ECS Project No. 08-10919 June 26, 2015 We recommend testing all shallow foundations to confirm the presence of foundation materials similar to those assumed in the design. We recommend the testing consist of hand auger borings with Dynamic Cone Penetrometer (DCP) testing performed by an engineer or engineering technician. 7. GENERAL COMMENTS The borings performed at this site represent the subsurface conditions at the location of the borings only. Due to the prevailing geology and presence of existing undocumented fill, changes in the subsurface conditions can occur over relatively short distances that have not been disclosed by the results of the borings performed. Consequently, there may be undisclosed subsurface conditions that require special treatment or additional preparation once these conditions are revealed during construction. Our evaluation of foundation support conditions has been based on our understanding of the site and project information and the data obtained in our exploration. The general subsurface conditions utilized in our foundation evaluation have been based on interpolation of subsurface data between and away from the test holes. If the project information is incorrect or if the structure locations (horizontal or vertical) and/or dimensions are changed, please contact us so that our recommendations can be reviewed. The discovery of any site or subsurface conditions during construction which deviate from the data outlined in this exploration should be reported to us for our evaluation. The assessment of site environmental conditions for the presence of pollutants in the soil, rock, and groundwater of the site was beyond the scope of this exploration. The recommendations outlined herein should not be construed to address moisture or water intrusion effects after construction is completed. Proper design of landscaping, surface and subsurface water control measures are required to properly address these issues. In addition, proper operation and maintenance of building systems is required to minimize the effects of moisture or water intrusion. The design, construction, operation, and maintenance of waterproofing and dampproofing systems are beyond the scope of services for this project.

A geotechnical engineering study conducted for a civil engineer may not fulfill the needs of a construction contractor or even another civil engineer. Because each geotechnical engineering study is unique, each geo- technical engineering report is unique, prepared solelyfor the client. No one except you should rely on your geotechnical engineering report without first conferring with the geotechnical engineer who prepared it. And no one - not even you - should apply the report for any purpose or project except the one originally contemplated. Read the Full Report Serious problems have occurred because those relying on a geotechnical engineering report did not read it all. Do not rely on an executive summary. Do not read selected elements only. A- Geotechnical Engineering Report Is Based on A Unique Set of Project -Specific Factors Geotechnical engineers consider a number of unique, project -specific factors when establishing the scope of a study. Typical factors include: the client's goals, objectives, and risk management preferences; the general nature of the structure involved, its size, and configuration; the location of the structure on the site, and other planned or existing site improvements, such as access roads, parking lots, and underground utilities. Unless the geotechnical engi- neer who conducted the study specifically indicates otherwise, do not rely on a geotechnical engineering report that was: not prepared for you, • not prepared for your project, • not prepared for the specific site explored, or • completed before important project changes were made. Typical changes that can erode the reliability of an existing geotechnical engineering report include those that affect: the function of the proposed structure, as when it's changed from a parking garage to an office building, or from alight industrial plant to a refrigerated warehouse, • elevation, configuration, location, orientation, or weight of the proposed structure, • composition of the design team, or • project ownership. As a general rule, always inform your geotechnical engineer of project changes - even minor ones - and request an assessment of their impact Geotechnical engineers cannot accept responsibility or liability for problems that occur because their reports do not consider developments of which they were not informed. Subsurface Conditions Can Change A geotechnical engineering report is based on conditions that existed at the time the study was performed. Do not rely on a geotechnical engineering reportwhose adequacy may have been affected by: the passage of time; by man-made events, such as construction on or adjacent to the site; or by natu- ral events, such as floods, earthquakes, or groundwater fluctuations. Always contact the geotechnical engineer before applying the report to determine if it is still reliable. A minor amount of additional testing or analysis could prevent major problems. Most Geotechnical Findings Are Professional Opinions Site exploration identifies subsurface conditions only at those points where subsurface tests are conducted or samples are taken Geotechnical engineers review field and laboratory data and then apply their professional judgment to render an opinion about subsurface conditions throughout the site. Actual subsurface conditions may differ -sometimes significantly from those indi- cated in your report. Retaining the geotechnical engineer who developed your report to provide construction observation is the most effective method of managing the risks associated with unanticipated conditions. A Report's Recommendations Are Not Final Do not overrely on the construction recommendations included in your re- port. Those recommendations are not final, because geotechnical engineers develop them principally from judgmentand opinion. Geotechnical engineers can finalize their recommendations only by observing actual subsurface conditions revealed during construction. The geotechnical engi- neer who developed your report cannot assume responsibility or liability for the report's recommendations if that engineer does not perform construction observation A Geotechnical Engineering Report Is Subject to Misinterpretation Other design team members' misinterpretation of geotechnical engineer- ing reports has resulted in costly problems Lower that risk by having your geotechnical engineer confer with appropriate members of the design team after submitting the report. Also retain your geotechnical engineer to review pertinent elements of the design team's plans and specifications. Contractors can also misinterpret a geotechnical engineering report. Reduce that risk by having your geotechnical engineer participate in prebid and preconstruction conferences, and by providing construction observation. Do Not Redraw the Engineer's Logs Geotechnical engineers prepare final boring and testing logs based upon their interpretation of field logs and laboratory data To prevent errors or omissions, the logs included in a geotechnical engineering report should never be redrawn for inclusion in architectural or other design drawings Only photographic or electronic reproduction is acceptable, but recognize that separating logs from the report can elevate risk. Give Contractors a Complete Report and Guidance Some owners and design professionals mistakenly believe they can make contractors liable for unanticipated subsurface conditions by limiting what they provide for bid preparation. To help prevent costly problems, give con- tractors the complete geotechnical engineering report, butpreface it with a clearly written letter of transmittal In that letter, advise contractors that the report was not prepared for purposes of bid development and that the report's accuracy is limited; encourage them to confer with the geotechnical engineer who prepared the report (a modest fee may be required) and/or to conduct ad- ditional study to obtain the specific types of information they need or prefer. A prebid conference can also be valuable Be sure contractors have sufficient time to perform additional study. Only then might you be In a position to give contractors the best information available to you, while requiring them to at least share some of the financial responsibilities stemming from unantici- pated conditions. Read Responsibility Provisions Closely Some clients, design professionals, and contractors do not recognize that geotechnical engineering is far less exact than other engineering disciplines. This lack of understanding has created unrealistic expectations that have led to disappointments, claims, and disputes To help reduce the risk of such outcomes, geotechnical engineers commonly include a variety of explanatory provisions in their reports. Sometimes labeled "limitations" many of these provisions indicate where geotechnical engineers' responsibilities begin and end, to help others recognize their own responsibilities and risks. Read these provisions closely Ask questions Your geotechnical engineer should respond fully and frankly. Geoenvironmental Concerns Are Not Covered The equipment, techniques, and personnel used to perform a geoenviron- mental study differ significantly from those used to perform a geotechnical study. For that reason, a geotechnical engineering report does not usually re- late any geoenvi ron mental findings, conclusions, or recommendations; e.g., about the likelihood of encountering underground storage tanks or regulated contaminants. Unanticipated environmental problems have led to numerous project failures. If you have not yet obtained your own geoenvironmental in- formation, ask your geotechnical consultant for risk management guidance. Do not rely on an environmental report prepared for someone else. Obtain Professional Assistance To Deal with Mold Diverse strategies can be applied during building design, construction, op- eration, and maintenance to prevent significant amounts of mold from grow- ing on indoor surfaces. To be effective, all such strategies should be devised for the express purpose of mold prevention, integrated into a comprehensive plan, and executed with diligent oversight by a professional mold prevention consultant Because just a small amount of water or moisture can lead to the development of severe mold infestations, a number of mold prevention strategies focus on keeping building surfaces dry. While groundwater, wa- ter infiltration, and similar issues may have been addressed as part of the geotechnical engineering study whose findings are conveyed in -this report, the geotechnical engineer in charge of this project is not a mold prevention consultant, none of the services performed in connection with the geotechnical engineer's study were designed or conducted for the purpose of mold prevention. Proper implementation of the recommendations conveyed in this report will not of itsell he sufficient to prevent mold from growing in or on the struc- ture involved.
