Statement of Work (SOW) For

GEOLOGIC INVESTIGATION

Upper Clear Boggy Creek Site 26

The Contractor shall furnish the personnel, equipment, labor, materials, transportation, and facilities required to perform the services described herein:

I. INTRODUCTION

Upper Clear Boggy Creek Site No. 26 is a Flood Water Retarding Structure located in Pontotoc County, Oklahoma. The dam was constructed in 1980 as a low hazard class (A) structure, but due to development downstream and changes in dam safety criteria the structure has been reclassified as a high hazard structure. The local project sponsors have chosen to rehabilitate the dam to maintain the flood control benefits and meet safety criteria. A Geologic Investigation Report was completed November 13, 2019. Since the completion of the report the design for the rehabilitation of the structure has been amended and now includes the following modifications to the structure: raise the top of dam, modify the principal spillway and construction of a RCC stepped auxiliary spillway.

The Natural Resources Conservation Service, Oklahoma State Office (Oklahoma NRCS) is requesting the A&E provide support in the effort to gather the appropriate level of geologic data for Upper Clear Boggy Creek 26 to support the proposed modifications. The objective of this statement of work (SOW) is to provide drilling and field service to support a supplemental geologic investigation (GI). The resultant supplemental report produced by NRCS and the 2019 Geologic Report will be used to support the proposed modifications to the dam and associated appurtenances to bring the dam into compliance with current NRCS safety criteria and performance standards for high hazard dams, and to extend the service life of the dam to 100 years while providing the required flood protection.

The contracting firm shall perform all drilling activities, sample collection, water level readings, site preparations, and backfilling operations. The contracting firm shall provide appropriate equipment and materials for drilling, testing, and sampling. Upon completion of drilling activities, the contracting firm shall return site to original conditions or as directed by the CO. The contracting firm will be responsible for locating all underground utilities and contacting Oklahoma One Call before drilling operations begin. Some of the boreholes may not be easily accessible, it is the responsibility of the contracting firm to prepare site conditions to for drilling operations.

The data to be collected is based on five areas of focus; centerline of the dam, downstream (embankment) toe/foundation, proposed combined principal and auxiliary spillway, and borrow areas. Specific characteristics are spelled out below. These shall not be construed as the limit of the investigation and testing, but as a guide. It should be noted that some of the boreholes are listed in multiple locations below.

A. Centerline of Dam All test holes penetrating the existing embankment shall follow guidance outlined in the U.S.

Army Corps of Engineers ER 1110-1-1807, Procedures for Drilling in Earth Embankments (dated March 2006).

Three (3) boreholes shall be located along the centerline of the existing embankment and the proposed alignment of the RCC Spillway. These borings will provide data to help define engineering characteristics of the embankment.

Boreholes along the centerline shall advance to a depth of one (1) times the embankment height (where drilled). The approximate depths are depicted in Table 1 of the Field Investigation Plan (FIP); depths may vary once borehole locations are surveyed and drilled.

Drilling typically advances at 5 feet intervals; the Oklahoma NRCS Geologist shall determine the method and appropriate level of sampling as drilling advances. When sampling with splitspoon, standard penetration tests (SPT) shall be performed at each interval sampled.

Samples collected shall represent each interval drilled in uniform materials or each differing material should a change occur before reaching the next sampling interval. Continuous sampling may be used if deemed necessary by the Oklahoma NRCS Geologist to gain a more detailed representation of the materials encountered between planned intervals. Depth to ground water, if reached, shall be recorded and monitored over a 24-hour period.

B. Downstream Toe / Foundation

Seven (7) boreholes are located along the existing embankment toe and to extents representing the planned expansion, for purposes of investigating foundation conditions.

The approximate depths are depicted in Table 1 of the FIP; depths may vary once borehole locations are surveyed and drilled. Due to lack of pre-existing geologic information two (2) of the holes, referenced as 220A and 223A in the FIP, will serve as companion holes for 220 and 223 to determine Shelby Tube sampling intervals.

These boreholes shall advance to the same depths prescribed for the centerline. Drilling shall advance at 2.5 feet intervals or tighter (drilling adjusted) with SPT analysis performed at each interval. Where soil conditions allow, undisturbed samples will be considered so that

- 4 -an appropriate number are available for compressive/shear strength analyses. Continuous sampling shall be conducted between SPT and/or undisturbed sampling intervals to allow for detailed logging, and sample separation if material changes occur. Drilling/sampling intervals may change to 5 feet intervals, and continuous sampling may be discontinued based on materials encountered and/or with depth; this will be determined by conditions found in the field and the Oklahoma NRCS Geologist. Depth to ground water, if reached, shall be recorded and monitored over a 24-hour period.

C. Principal and Auxiliary Spillway

A detailed description of the strata underlying the proposed combined principal and auxiliary spillway alignment is required to evaluate the conditions that could impact the installation of the inlet tower, the conduit, stepped RCC spillway and the impact basin.

Eight (8) boreholes are located within the footprint of the proposed spillway. The new location of the proposed combined spillway is located within the existing dam/embankment.

The approximate depths are depicted in Table 1 of the FIP; depths may vary once borehole locations are surveyed and drilled. Some of the boreholes may not be easily accessible. The A&E shall determine how best to access these locations. All test holes penetrating the existing embankment shall follow guidance outlined in the U.S. Army Corps of Engineers ER 1110-1-1807, Procedures for Drilling in Earth Embankments (dated March 2006).

Drilling typically advances at 5 feet intervals; field operations shall determine the appropriate interval, method, and level of sampling as drilling advances. Where drilling advances through the existing embankment (including embankment materials encountered at either toe), it is important to record where distinct changes in materials occur (color inclusive), and depths water was encountered (if any). Accurate recording of water levels along this alignment is critical to evaluating the conditions that may influence the method of construction (cut and cover, boring and jacking, or other).

D. Borrow Area Approximately seven (7) boreholes will be placed in the proposed borrow areas to identify and classify the materials according to their availability and suitability for their intended use.

Drilling with helical flight augers and collecting large bag/buckets samples is the proposed method, but field conditions will dictate the how sample collection is achieved. The approximate depths are depicted in Table 1 of the FIP; depths may vary once borehole locations are surveyed and drilled. Additional sampling may be required and boring depths may vary based on field conditions encountered while drilling.

Investigations shall extend at least 2 feet below the expected depth of material excavation unless consolidated material, not suitable for borrow, is encountered. Additional areas may be investigated in the field based on varying subsurface conditions; as determined by the Oklahoma NRCS geologist.

Samples representing each defined material required for use shall be collected for laboratory testing. The quantities and location of desirable materials, and the areas in which it may be most conveniently developed shall be determined. A preferred method of excavation shall be determined. Depth to ground water, if reached, shall be recorded and monitored over a 24 hour period.

Drilling/excavating, sampling, and field testing shall conform to NRCS NEH Part 631, Chapter 5 Engineering Geology Logging, Sampling, and Testing, as well as the prescribed criteria below unless prior approval to deviate is obtained from the Oklahoma NRCS CO. NRCS will be responsible for logging, packaging and transportation of sample materials Test holes penetrating the existing embankment shall follow guidance http://okticketentry.korterraweb.com/

- 7 -outlined in the U.S. Army Corps of Engineers ER 1110-1-1807, Procedures for Drilling in Earth Embankments (dated March 2006) as well as the prescribed criteria below unless directed to deviate by the Oklahoma NRCS Geologist.

a). Drilling / Excavating

1). Augering

Hollow-stem auger drilling, capable of pushing a minimum 3 inch diameter Shelby tube, drilling with continuous sampling, and driving split-spoon/split-barrel samplers, shall be the primary method considered. It shall be accomplished as prescribed by ASTM D6151-08, Standard Practice for Using Hollow-Stem Augers for Geotechnical Exploration and Soil Sampling, or comparable method.

Continuous helical flight augers may be used where competent soils allow; however, sampling cannot be compromised by cuttings or materials that slough into the hole during the sampling process.

2). Rock Coring

No rock coring intervals were proposed in the FIP. Rock coring may be proposed where deemed necessary, to obtain the material characteristics discussed above.

Oklahoma NRCS CO approval shall be obtained prior to proceeding. If approved, rock coring shall be accomplished as prescribed by ASTM D2113-08, Standard Practice for Rock Core Drilling and Sampling of Rock for Site Investigation, or comparable method. The barrel shall be a double tube core barrel, NX size or larger, and equipped with a split inner barrel (preferred). The maximum length of the coring "run" shall be limited to 10 feet; 5 feet is typical. Caution should be taken to ensure that core recovered is not altered or damaged by drilling or recovery to the extent the core does not represent the rock material or feature being sampled.

The rock core samples shall be placed in properly marked waxed cardboard or wooden core boxes, furnished by the A&E or drilling contractor. The depth of each sample run shall be clearly marked for proper identification and photographing. Rock cores shall be photo-documented according to ASTM D5079-08, Standard Practices for Preserving and Transporting Rock Core Samples.

Rock cores shall be preserved and transported as prescribed in ASTM D5079-08.

Rock cores shall be retained and stored until acceptance of the final design. The Oklahoma NRCS CO shall work with the A&E to establish a suitable storage location, and disposition options. The Oklahoma NRCS CO shall also determine whether any or all core samples shall be retained for further evaluation and/or testing beyond acceptance of the final design.

All sampling materials, rock coring, and/or data materials to be tested for the Soils Mechanics Report will be delivered to the following location by the NRCS:

Lincoln, Nebraska

3). Test Pits No test pits were proposed in the FIP. Test pits, trenches, or other excavations, may be proposed within the borrow areas, or elsewhere as deemed necessary, to obtain the material characteristics discussed above. Oklahoma NRCS CO approval shall be obtained prior to proceeding. Observations of the excavation process may be used to assess the excavation characteristics of the materials that might be encountered during construction.

4). Monitoring/Observation Wells and Piezometers No monitoring/observation wells or piezometers were proposed in the FIP. The A&E may elect to install monitoring/observation wells or piezometers to aid in determining the phreatic and/or piezometric surfaces and to monitor seepage, should field conditions warrant. NRCS CO approval shall be obtained prior to proceeding. All wells/piezometers, if approved, shall be constructed and abandoned according to OWRB rules and regulations.

Pipe temporarily placed in a drill hole to keep it open for obtaining a static water level shall not be considered a monitoring/observation well, or piezometer, as such pipe will be required to be removed upon obtaining the water level measurement(s). The depth at which a drill hole collapses or becomes restricted shall be recorded in the water level measurements.

5). Drill Hole Plugging and Test Pit Backfilling In the event water is encountered, drill holes and test pits shall remain open at least 24 hours, or until a change of less than 0.1 foot in water elevation is observed within 24 hours, so that a static groundwater level can be recorded. Drill holes which cannot be maintained open unaided, shall be lined with PVC casing or equivalent until static groundwater level is confirmed. Test pits that cannot remain open unaided, or where safety is an issue, shall be backfilled as soon as a practicably possible; a water level shall be recorded prior to backfilling.

All drill holes shall be plugged in accordance with OWRB rules and regulations.

ASTM D6151-08 may be used as a reference.

Test pits shall be backfilled to 6 inches above natural ground surface with excavated material and all ridges smoothed prior to leaving the pit area. Pits shall be checked a minimum of 24 hours after backfilling, and prior to mobilizing off site, in order to evaluate for settlement, and to correct if it has occurred.

Wash borings shall only be considered adequate for determining rough bedrock profiles or for reaching a depth to be sampled by other means and must be approved by the Oklahoma NRCS Geologist prior to utilization. The bit shall be fitted with deflectors to prevent soil disturbance below the depth drilled.

Geophysical soundings or probing shall not be used in lieu of drilling, however, where liquefaction may be of concern, cone penetration tests can be proposed to supplement the drilling/SPT data obtained. Prior approval from the Oklahoma NRCS CO shall be obtained.

- 9 -b). Sampling At a minimum, soil samples shall be collected every 5 feet or where material changes occur. In foundation materials, a tighter sampling interval may be required to further evaluate the underlying conditions and to support seismic evaluations. Sampling should reflect that approved in the FIP, unless field conditions warrant otherwise.

1). Shelby Tube Sampling

Shelby tubes shall be no less than 3 inches in diameter, and no less than 24 inches in length.

For triaxial compressive / shear testing, undisturbed samples shall be collected using the appropriate diameter and length of Shelby tube specified by the testing laboratory. Undisturbed sampling shall be performed according to ASTM D1587- 08(2012)e1, Standard Practice for Thin-Walled Tube Geotechnical Sampling of Soils.

Expandable plugs and end caps shall be used to seal the samples prior to transporting to the lab. The Shelby tubes, expandable plugs, and end caps will be provided by the contractor. Melted wax for sealing tubes is not allowed.

Undisturbed sample tubes shall be clearly labeled with waterproof materials showing, at a minimum, the top end of sample, the project name, test hole and sample number, sampled interval, length of sample recovered, name of collector, and date sample collected. Undisturbed sample tubes shall be handled, transported, and stored in an upright position to minimize disturbance after preservation and marking.

Care shall be taken to place samples in areas shielded from direct sunlight and/or exposure to extreme heat or freezing temperatures.

2). Split Spoon Sampling / Standard Penetration Test (SPT)

The minimum length of the sampler shall be 24 inches. The cutting shoe shall be of hardened steel and shall be replaced when it becomes dented, distorted, or in any way damaged. Core retainers, sand traps, or other devices shall be available at the worksite should the standard spoon not retain a sample. A ball check valve in the sampler head is required so fluid can escape through the top of the sampler.

Split spoon sampling shall be conducted in conjunction with standard penetration tests. In low density/loose sands, where there is a potential for liquefaction, ASTM D6066-11 Standard Practice for Determining the Normalized Penetration Resistance of Sands for Evaluation of Liquefaction Potential, shall be used.

ASTM D1586-11, Standard Test Method for Standard Penetration Test (SPT) and Split-Barrel Sampling of Soils, may be used as a reference.

The Oklahoma NRCS geologist shall prepare a sample list itemizing all samples collected using form SCS-ENG-534 – Soil Sample List or a comparable form approved by the Oklahoma NRCS CO prior to use.

The size of the sample shall be sufficient to perform the intended tests; the testing laboratory should be consulted as to volume requirements. Minimum sample size requirements are provided in NEH Part 631, Chapter 5.

Samples shall be handled, transported, and stored as prescribed in NEM 531, Subpart 531.14. Storage times need to reflect the testing protocol proposed. The

- 10 -laboratory should be consulted on containers, proper handling, and any special transport requirements.

c). Field Testing

The following shall be conducted where materials warrant:

1). Standard Penetration Testing This shall be performed in conjunction with split spoon sampling. This test shall be used to provide an indication of the relative density of tight consolidated deposits, unconsolidated deposits, and weak rock. It shall be performed per the requirements of ASTM D6066-11 for this investigation.

The usefulness of SPT results depends on the soil type, with fine-grained sands giving the most useful results, coarser sands and silty sands giving reasonably useful results, and clays and gravelly soils yielding results which may not be representative of the true soil conditions. SPT results in dry materials shall be noted, as the relative density and cohesiveness of the soils may change if wetted.

Results shall be evaluated and used to help determine seismic influences on the foundation and the potential for liquefaction of any underlying strata tested.

2). Acid Tests A 1.0 M HCl (1.0 molar) solution shall be prepared, and intervals suspect of having calcareous or carbonate components shall be tested. Reaction levels (none, weak, strong, or violent) shall be recorded on the log at the depths analyzed.

3). Field Dispersion Tests Where materials are suspect for dispersion, the NRCS Geologist shall perform field crumb tests to determine which samples will require further laboratory analysis confirmation. Photos of the test results at each time allotment shall be taken, and the results cited in the report.

4). Pocket Penetrometer Testing

Where determined pertinent to the design process, pocket penetrometer tests can be recorded on the ends of Shelby tube samples, within continuous sample intervals, or on other suitable samples.
