The typical soil profile encountered at the nine (9) soil test borings at the subject site is relatively uniform and includes surficial highly plastic silty residual soils underlain by non -plastic sandy silt and finally a silty sand. The surficial silty residual soil is highly plastic silt (MH) that was encountered at every test boring, and was 2.5 to 7.5 feet thick, moist and very stiff. The upper non -plastic sandy micaceous silt layer (ML) was encountered at five test borings and was 2.5 to 7.5 feet thick, moist and loose. The lower silty sand layer (SM) was encountered at every test boring except B-9 and was moist, very loose to loose and at least 17.5 feet thick. Neither groundwater nor bedrock was encountered during this subsurface exploration. 2. We conclude that the site is suitable for the planned construction, although the surficial highly plastic silt (MH) soils should be addressed during site preparation and earthwork. This soil shrinks and swells with moisture changes and was encountered in every test boring. 3. We offer the following design and construction recommendations for the proposed Dollar General at Statesville, NC: Site preparation should consist of removing the existing building, trees, vegetation and any topsoil layer, along with all other soft or unsuitable material from the proposed building envelope and associated pavement areas. As noted below, we recommend an undercut of the highly plastic silt (MH) where encountered at foundation, floor slab or pavement elevations. We recommend supporting the proposed building on shallow foundations bearing on undisturbed, competent non -plastic or low -plasticity residual soils and/or newly compacted controlled fill soils designed for an allowable net bearing pressure of up to 2,500 psf. We do not recommend bearing any foundations directly on the highly plastic silt (MH); if it is exposed at foundation elevation, we recommend a minimum 24-inch undercut. We recommend a modulus of subgrade reaction (k) of up to 100 pounds per cubic inch for structural design of the floor slab if the slab will be supported by competent, non -plastic residual or structural fill. This recommendation is based on the building pad areas passing a proofroll. We recommend a free -draining granular base as capillary break and vapor barrier. We do not recommend bearing the floor slab directly on the highly plastic silt (MH); if it is exposed at floor slab elevation, we recommend a minimum 18-inch undercut. Project Name: Dollar General Location: Statesville, NC Date: April 30, 2015 Project No. 15-063 We recommend standard thicknesses for both light and heavy-duty asphalt pavements, and that any dumpster areas are supported by concrete slab on grade. We do not recommend bearing any pavement directly on the highly plastic silt (MH); if it is exposed at pavement elevation, we recommend a minimum 18-inch undercut. This executive summary should be used in conjunction with the entire contents of the report, in order to gain a complete understanding of all conclusions and recommendations contained within the report. 2.0 PURPOSE AND SCOPE OF WORK The purpose of the subsurface exploration and geotechnical engineering evaluation was to explore the subsurface conditions at the site, collect representative samples of soil for examination in our laboratory (with testing as needed), and provide conclusions and recommendations for design and construction of the proposed Dollar General store in Statesville, North Carolina. CVET's scope of work included the following: • Drilling of nine (9) soil test borings at the site; • Collection of representative samples of soil from the soil test borings, and performance of lab testing of selected samples as needed; • Preparation of boring logs, boring location plan, and general subsurface profile; • Evaluation of the encountered subsurface conditions at the site; and • Preparation of this geotechnical report. 3.0 PROJECT INFORMATION This project consists of the construction of a new Dollar General store at the intersection of Salisbury Road (US Highway 70) and Bellwood Drive in Statesville, North Carolina, as shown on Figure 1 in Appendix A. The site is currently vacant with grassy cover, an existing building, and remains of trees which were recently removed from the site. Site grades generally slope from north to south, away from US Highway 70. The proposed development consists of the construction of an approximate 9,100 square foot facility, parking areas, dumpster pad area, and associated infrastructure, as shown on Figure 2 in Appendix A. Project information was provided by Mr. Derek Goddard of Blue Ridge Environmental Consultants on March 26, 2015. We have been provided the preliminary site plan that displays the proposed building location and parking areas. Project Name: Dollar General Location: Statesville, NC Date: April 30, 2015 Project No. 15-063 4.0 EXPLORATION PROCEDURES Exploration procedures for this project included drilling test borings at the site and laboratory testing of representative soil samples at our laboratory in Hickory, North Carolina. 4.1 Field Exploration The subsurface conditions at the site were explored by drilling a total of nine (9) soil test borings (denoted B-1 through B-9) at the locations indicated on Figure 2 — Boring Location Plan in Appendix A. The borings were drilled on April 13, 2015, extending to depths ranging from 10.0 to 20.0 feet below existing site grades. The boring locations were selected and located in the field by CVET using existing site features as a reference. Ground elevations at the boring locations were estimated from Google Earth and/or available GIS data. Therefore the boring locations and elevations shown on Figure 2 and 3 plus the boring logs should be considered approximate. Drilling was performed with a CME-550 ATV -mounted drill rig using continuous -flight hollow stem augers (HSA). Soil samples were obtained by means of the split -barrel sampling procedures in accordance with ASTM Specification D-1586; a 2-inch O.D., split -barrel sampler was driven into the soil a distance of 18 inches by means of an automatic hammer. The number of blows required to drive the sampler through the final 12-inch interval is termed the Standard Penetration Test "N" value and is indicated for each sample on the boring logs. This value can be used to provide an indication of the in -place relative density of cohesionless soils, but is a less reliable indicator of the consistency of cohesive soils. For cohesive soils, the measurement of unconfined compressive strength Qu is a better indicator of consistency; this value is also listed on the boring logs. Representative portions of each SPT sample were sealed in airtight containers and returned to our laboratory for classification, testing, and storage. See the individual soil test boring logs in Appendix B for more details. Note that the soil samples will be discarded after 30 dates from this report date, unless otherwise directed by Blue Ridge Environmental Consultants, P.A. 4.2 Laboratory Testing Representative samples of soil obtained during the field exploration were transported to CVET's laboratory in Hickory, North Carolina, where they were examined and classified by a geotechnical engineer. The soil samples were visually classified in general accordance with the Unified Soil Classification System (USCS), per ASTM D2487. Laboratory testing including soil moisture (per ASTM D2216), Grain Size Distribution (ASTM D422) and Atterberg limits for plasticity (per ASTM D4318); results are included in Appendix C. 5.0 SUBSURFACE CONDITIONS The subsurface conditions at the site are described in the following paragraphs Project Name: Dollar General Location: Statesville, NC Date: April 30, 2015 Project No. 15-063 5.1 Site Geology The site is located in the Piedmont Physiographic Province of North Carolina. The name "piedmont" means "foot -of -the -mountains" which reflect remnants of an ancient mountain range that has since been extensively weathered, decomposed and eroded to form rolling terrain and hillsides. The bedrock is metamorphic in nature (igneous or sedimentary rocks that have been changed by heat and/or pressure) and typically consists of schist, gneiss and/or granite. Extensive weathering over time has reduced the bedrock in -place to form overburden residual soils that range from clay topsoil to sandy silts and silty sandy that grade with depth back to saprolite and partially -weathered -bedrock. The degree of weathering varies both laterally and vertically. Based on the 1985 North Carolina Geologic map, the site appears to be underlain by fine-grained granitic gneiss (CZbz). 5.2 Soils A generalized subsurface profile has been prepared for the site - see Figure 3 in Appendix A. Soil boring logs are included in Appendix B. The typical soil profile encountered at the nine (9) soil test borings at the subject site is relatively uniform and includes surficial highly plastic silty residual soils underlain by non -plastic sandy silt and finally a silty sand. The surficial silty residual soil is a highly plastic silt (MH) that was encountered at every test boring, and was 2.5 to 7.5 feet thick, moist and very stiff. The upper non -plastic sandy micaceous silt layer (ML) was encountered at five test borings and was 2.5 to 7.5 feet thick, moist and loose. The lower silty sand layer (SM) was encountered at every test boring except B-9 and was moist, very loose to loose and at least 17.5 feet thick. 5.3 Bedrock Bedrock was not encountered in the test borings. 5.4 Groundwater Groundwater was not encountered during this subsurface exploration. Note that each borehole was left open for only a short period of time during the drilling operation, so the detection of groundwater during this brief period is difficult. Also note that soil moisture and groundwater conditions vary depending on conditions such as temperature, precipitation and season. Therefore soil moisture and groundwater location at other times of the year may vary from those observed at the time of this subsurface exploration and as described in this report. The borehole cave-in depths are listed on the boring logs. In this geology, the cave-in depth of a boring is sometimes an indication of the stabilized water level, although the water level may be a few feet below the cave-in depth and therefore cannot be directly observed. At other times, it means nothing in relation to the groundwater location. If the location of the groundwater elevation is important at this site, we recommend the installation of temporary observation wells. Project Name: Dollar General Location: Statesville, NC Date: April 30, 2015 Project No. 15-063 6.0 RECOMMENDATIONS FOR DESIGN AND CONSTRUCTION The following recommendations are provided for design and construction of the proposed Dollar General in Statesville, North Carolina. The recommendations stated herein shall not be applied to any other project, or used in conjunction with any other recommendation, and shall be used explicitly for this project. 6.1 Site Preparation Site preparation should consist of removing the existing buildings, trees, vegetation and topsoil layer, along with all other soft or unsuitable material from the proposed building envelope and associated pavement areas. Some fills soils should be expected at the former building location. Once stripping and rough excavation to grade has been accomplished, the exposed subgrade should be evaluated by proofrolling. Proofrolling consists of driving the appropriate equipment, typically a dump truck with axle weights of 10 or 20 tons for single and double axles respectively, over the subgrade at a walking pace. The proofrolling equipment should first make overlapping passes across the subgrade in one direction, followed by passes in a perpendicular direction. Unstable areas that exhibit excessive rutting, pumping and similar distress should be undercut to a competent material and backfilled with controlled fill or other materials as recommended by a qualified geotechnical engineer. We recommend that the proofrolling be observed by a qualified engineer or engineering technician. As noted below, we recommend an undercut of the highly plastic silt (MH) where encountered at foundation, floor slab or pavement elevations. 6.2 Earthwork At the time of this report, CVET has not been provided with the proposed grading plan or the finished floor elevation, so site grading is unknown. It is expected that fill soils from an off -site source will be needed for this project. All fill soils should be compacted to at least 95 percent of the maximum dry density obtained in accordance with ASTM Specification D-698, Standard Proctor Method, with a moisture content within +/- 3% of the optimum moisture content (OMC). Acceptable fill soils should be soil that has less than 5 percent organic content and a liquid limit and plasticity index less than 50 and 20, respectively. Soils with USCS group symbols of SP, SW, SM, SC, and ML are recommended for use as controlled fill, although it is important to note that silty soils are very moisture sensitive and not as strong as sandy soils. As noted above, plastic silts (MH) are not good structural fill soils and should be limited to placement in deep fill areas. All fill soils should be placed in horizontal loose lifts and compacted with adequately - sized equipment. Loose lift thicknesses will vary depending on the size of the compaction equipment: we recommend a maximum of 8 inches for large self-propelled compactors, 6 inches for small self-propelled compactors, and 4 inches for remote -controlled compactors and hand - operated equipment (plate tampers, wacker-packers, or jumping jacks). Vibratory smooth -drum rollers are appropriate for cohesionless/coarse-grained soils while sheepsfoot rollers are appropriate for cohesive/fine-grained soils. Project Name: Dollar General Location: Statesville, NC Date: April 30, 2015 Project No. 15-063 We recommend that positive site drainage is maintained during earthwork operations to prevent the ponding of water on exposed subgrades. Soil subgrades should be protected from inclement weather (rain especially) by 'sealing' the subgrades prior to forecasted inclement weather. 'Sealing' can be performed by rolling with a smooth steel -drum roller without vibration. Ruts should not be created during the 'sealing' operation. Prior to the placement of additional fill, the 'sealed' subgrade should be scarified. If earthwork is performed during winter months or after inclement weather, the subgrade soil conditions could potentially be more unstable due to wet soil conditions, which could potentially require stabilization or undercutting. 6.3 Groundwater Control We do not anticipate that groundwater control will be necessary for this project, since groundwater was not encountered in the test borings. Note that soil moisture and groundwater conditions vary depending on conditions such as temperature, precipitation and season. Therefore soil moisture and groundwater location at other times of the year may vary from those observed at the time of this subsurface exploration and as described in this report. 6A Foundations At the time of this report CVET has not been provided with the proposed grading plan or the finished floor elevation, so finished site grades are unknown. It is unclear if the foundations will bear on the existing residual soils or new structural fill soils. We recommend supporting the proposed building on shallow foundations bearing on undisturbed, competent residual soils and/or newly compacted controlled fill. Shallow foundations for buildings should be designed for an allowable net bearing pressure of up to 2,500 pounds per square foot. We recommend minimum foundation widths and embedment depths of 16 and 18 inches, respectively. Because the surficial elastic silt layer encountered at this site at all borings is moisture sensitive and subject to shrink/swell, we do not recommend bearing any foundations directly on the elastic silt, especially the perimeter foundations which have a greater chance of being subjected to surface water. Instead we recommend an undercut of the elastic silt to a depth of at least 24 inches where encountered at the foundation bearing elevation and replacement with quality non -plastic or low -plasticity fill materials or ABC gravel. If fill soils will be placed to reach final grades, we recommend a 24-inch buffer of non -plastic fill soils between the bottom of foundations and the MH soils. Based upon our experience with Dollar General stores we anticipate that structure consist of a tum-down concrete slab on grade floor system with masonry veneer; maximum loads of 50 kips for columns and 3 klf for walls are anticipated. A site -specific settlement analysis has not been performed. However, based upon the expected loading and the requirement that the foundations bear on competent residuum or structural fill soils (to be verified by CVET or another qualified CMT firm), we expect total settlements of 11 Project Name: Dollar General Location: Statesville, NC Date: April 30, 2015 Project No. 15-063 structure foundations to be on the order of l inch or less. In general, differential settlements between building components arc expected to be on the order of 1/3 to 1/2 of the total settlements. We expect settlements in the building foundations to occur relatively soon after the loads are applied. 6.5 Floor Slabs We believe that a concrete slab -on -grade floor system is appropriate for the proposed building additions. Regardless if the floor slab will bear on controlled fill or undisturbed residual soil, we recommend a modulus of subgrade reaction (k) of up to 100 pounds per cubic inch for structural design of the floor slab, pending the slab is bearing on structural fill soil. This value is representative of a 1-ft square loaded area and may need to be adjusted depending the size and shape of the loaded area depending on the method of structural analysis. The floor slab should be isolated from building foundations unless the connection is designed to accommodate anticipated foundation settlement. Similar to foundation and pavement areas, the subgrade for the entire floor slab area should be proofrolled (before foundation construction makes proofrolling impractical) to ensure that the subgrade is competent, and to locate any soft or incompetent areas that require undercutting and replacement with controlled fill soils. We recommend the use of 4 to 6 inches of free -draining granular material (NCDOT No. 57 stone or recycled concrete) as both aggregate base course under the slab and capillary break. Although not expected for this project, the use of a vapor retarder should be considered beneath concrete slabs on grade which will be covered with wood, tile, carpet or other moisture -sensitive or impervious coverings, per ACI 302 and/or ACI 360. If elastic silt is exposed at the floor slab elevation, we recommend undercut of at least 18 inches of the silt, and replacement with quality non -plastic or low -plasticity fill materials, because the plastic silts are moisture sensitive and prone to shrink/swell with moisture changes. If fill soils will be placed to reach final grades, we recommend an 18-inch buffer of non -plastic fill soils between the bottom of the floor slab and the MH soils. 6.6 Pavements Traffic load conditions for this project have not been provided. Pavement for this project is assumed to consist of standard or light -duty asphalt parking areas (only personal vehicle traffic) and heavy-duty asphalt drives (drive lanes, buses, trucks, etc.). Based on the subsurface conditions encountered in the test borings, and assuming all pavement areas pass a proofroll as described in section 6.1 of this report, we recommend standard thicknesses of 2, 0 and 6 inches for surface course, base course and ABC crushed stone, respectively, for standard or light -duty pavement. For heavy-duty pavement, we recommend thicknesses of 1.0, 2.5 and 8 inches for surface course, base course and ABC crushed stone, respectively. We recommend an 8-inch thick Portland cement concrete slab bearing on 4 inches of ABC crushed stone for the approach and slab for any trash dumpster on site. If concrete pavements are desired, we recommend a minimum of 6 inches of concrete overlying 4 inches of ABC crushed stone base. The concrete should be air -entrained and have a minimum of 4,500 psi after 28 days of laboratory curing per ASTM C-31. Based on test borings B-5 through B-9, elastic silt will be exposed at some of the 7 Project Name: Dollar General Location: Statesville, NC Date: April 30, 2015 Project No. I5-063 pavement subgrade elevation; we recommend an undercut of at least 18 inches of the elastic silt and replacement with quality non -plastic or low -plasticity materials, because the plastic silts are moisture sensitive and prone to shrink/swell with moisture changes. If fill soils will be placed to reach final grades, we recommend an 18-inch buffer of non -plastic fill soils between the pavement subgrade and the MH soils. Careful control of stone water is one of the best ways to endure adequate long-term performance of any pavement. The surface of the pavement should be sloped to gutters and/or catch basins to prevent water from ponding and infiltrating through the pavement into the sub -base and subgrade. We recommend compaction testing of the ABC crushed stone base prior to asphalt/concrete placement, and full-time inspection during asphalt/concrete placement. 6.7 Construction Materials Testing and Special Inspections Construction materials testing (CMT) and inspection should be performed at regular intervals throughout the course of the project. CVET is qualified for this work and would be pleased to provide these services during construction. 7.0 LIMITATIONS This report has been prepared for the exclusive use of Blue Ridge Environmental Consultants, P.A. and their agents for specific application to the referenced property, in accordance with generally accepted soils and foundation engineering practices. No warranties, express or implied, are intended or made. The conclusions and recommendations presented in this report are based on the specific test borings and laboratory testing performed as part of our scope of work, and do not reflect variations in subsurface conditions that may exist between test boring locations or in unexplored portions of the site. Note that the soil and laboratory test data presented in this report are for the specific time of this subsurface exploration. While the type of material encountered in the test borings will not likely change significantly over time, the properties of the materials can and will change over time, including soil moisture content, density, consistency, SPT "N" values, etc. Fluctuations in the groundwater level can have a significant impact on the material properties, as can seasonal changes. Site safety, excavation support related to OSHA requirements, and construction dewatering requirements are the responsibility of others, not CVET. In the event changes are made to the proposed construction plans, design or location of the project as described within this report, the conclusions and recommendations provided in this report shall not be considered valid unless CVET is given the opportunity to review the changes, and either verifies or modifies the conclusions and recommendations contained in this report in writing.
