In addition, supplemental PWS will be provided at the task order level.

2. DIRECTION OF WORK. The Contractor will initiate field exploration operations at designated work areas and to perform related laboratory testing through the issuance of either one or multiple task orders. Task orders will identify the purpose and location of the required field exploration, the location, number, and depth of soil borings, Cone Penetrometer Tests (CPTs), vibracores, or other field sampling or test procedures, the frequency of soil samples to be obtained, the laboratory tests to be performed on the samples, the required completion date of the work, and any special requirements or conditions. The Contractor shall begin the field exploration at the designated work site in accordance with the task order scope requirements. The Contractor shall develop and provide a site-specific safety plan to the Safety Officer for review prior to issuance of an NTP for each task order as specified in Section H of this contract. A drilling plan, if required for a task order, shall be developed and provided to the Safety Officer for review prior to issuance of notice to proceed (NTP). If laboratory testing is directed by a separate task order, then the Contractor shall begin laboratory testing of the soil samples within five (5) calendar days after receipt of the NTP for that task order. The Government reserves the right to set aside a certain portion of field exploration work to be performed by Government personnel or other commercial sources which would be reflected in the task order PWS or edited via modification. Testing of samples obtained by Government personnel may be designated for testing by the Contractor or may be tested at a Government and/or other commercial laboratory as selected by the Government.

3. SUPERVISION OF WORK. The Contractor shall be responsible for supervision of geotechnical field exploration and laboratory testing of soil samples. The Contractor shall assign a professional engineer or a professional geologist to supervise the work to be performed under each individual task order. The Contractor’s representative shall be responsible for coordinating the field operations to ensure that field procedures and directions specified in this contract are being followed. In addition, the Contractor shall be responsible for ensuring that the soil samples are being properly obtained and handled and that the samples are representative of the subsurface materials being encountered. The Contractor's representative shall communicate with the Contracting Officer’s Representative (COR) during the field operations and advise of any difficulties encountered in the performance of the work. Upon receipt of the Field logs, described in paragraph 14, RECORDS, the Contractor's representative shall review the logs for completeness and for agreement with the samples obtained. Upon receipt of directions for laboratory testing, the Contractor's representative shall inform laboratory personnel of the tests to be performed and shall supervise the testing to ensure that proper testing procedures are followed and that test results are properly recorded. The presence of the COR during the drilling operations and/or the laboratory testing shall not relieve the Contractor of the responsibilities specified in this paragraph.

4. LOCATION OF WORK. The location of the field exploration to be performed will be identified in each task order. Locations will include terrain of varying types, steepness, and consistencies ranging from hard-surfaced dry land to soft marsh lands, including swamps and dredged material placement areas, lands with excessive moisture or soft to very soft surface and subsurface conditions, partially to fully submerged areas with varying depths of ponded or standing water, and areas which may be covered by heavy vegetation or brush.

Locations may also include inland waterways and channels, portions of other bodies of water, and waters of and in close proximity of deep draft navigation channels including entrance channels offshore. The locations of the projects will, at times, be on islands that are only accessible by water. The exact location of each field boring, vibracore, CPT, or other field sampling or testing to be performed will either be provided to the contractor in the form of horizontal coordinates, be staked by the COR, be provided in relation to an existing physical or topographic feature, or be positioned in accordance with other instructions provided in the individual task orders.

The locations of borings specified in the task order or task order attachments shall not be changed unless the contract is modified.

5. ACCESS TO BORING LOCATIONS. The Contractor shall be required to perform clearing of vegetation where necessary to provide access for field exploration equipment. Where clearing is needed as determined by the Government, one or more of the equipment types listed in paragraph 13, EARTHWORK may be ordered by the Government for use in a task order. Rights-of-Entry or assurances that field exploration and associated clearing and earthwork activities are permitted in the designated areas will be furnished to the Contractor by the Government prior to the initiation of the field work. Access to the project sites accessible only by water may be obtained via public or private boat ramps or other launching sites identified by the Contractor. The Contractor shall exercise care in the use of the public ramps to avoid disturbance to the area and shall be responsible for leaving the area in a condition comparable to condition prior to the work. If private ramps are used, the Contractor is responsible to make arrangements with the owners for their use.

6. INCLEMENT WEATHER AND UNFORESEEN SITE CONDITIONS. Due to the nature of the field work required under this PWS, it is anticipated that inclement weather and unforeseen site conditions may cause field work delays.

a. Weather Delays. Routine inclement weather is considered to be any inclement weather that would reasonably be anticipated for the project site location and season during which the work is planned to be performed. Every effort will be made to accommodate the possibility of routine inclement weather delays in the work schedule for each task order. Full or partial days when field work cannot be accomplished due to routine inclement weather will not be paid for separately. The Contractor should take into account the potential for delays to field work schedules and costs due to the effects of routine inclement weather. The exception to routine inclement weather is the occurrence of unusual weather that causes extended limitations to site access and field operations, for example hurricanes, flooding, winter freezing storms, or other unusual events. Should unusual weather events occur that create extended periods of time whereby the work cannot continue, the Contractor shall notify the Government at the earliest possible time after these conditions are anticipated or encountered so that a determination can be made whether to pursue a task order modification. No additional time or work will be paid for without a formal task order modification issued in advance of the additional time or work.

b. Unforeseen Site Conditions. The term “unforeseen site conditions” is defined as conditions that could not reasonably be foreseen by the Government or the Contractor prior to task order award. The Contractor is responsible for visiting the proposed exploration site, determining access requirements for the exploration sites, including for challenging locations, becoming familiar with existing utilities at the project site, and estimating the field work schedule and costs, based on sound judgment and experience, prior to task order award. Should unforeseen site conditions that result in work delays and/or additional cost to the Contractor be encountered after task order award, the Contractor shall notify the Government at the time of discovery of the related site conditions so that a determination can be made whether to pursue a task order modification. Other field work included in the task order, and not affected by the unforeseen site condition, should be continued in order to maintain the completion schedule as closely as possible. No additional time or work will be paid for without a formal task order modification issued.

7. FIELD EQUIPMENT. Equipment to be furnished and utilized by the Contractor for geotechnical sampling shall be dependable equipment in good condition and of sufficient size to efficiently perform the sampling and testing to the required depths, at the required locations, and within the approved time period specified for the work. All equipment is subject to approval by the COR prior to the commencement of the required work and shall be maintained in good working condition by the Contractor throughout the drilling operations.

If a pipeline is detected at a proposed field exploration element (boring, CPT, vibracore, or other exploration type), then the Contractor shall relocate the element 100-feet away from such pipeline and identify the revised locations on the exploration layout. Approval for relocation of an element shall be obtained from the Government prior to performing the work.

11. BORING TYPES AND SAMPLING METHODS. Required boring and sampling methods will be specified in the individual task orders as undisturbed, disturbed, and/or environmental sample borings. Borings, as defined in this document, include field exploration that requires drilling or direct push to advance sampling equipment used to obtain subsurface samples for examination and testing. Field borings and sampling procedures and equipment shall be appropriate for the type, depth, and purpose of the samples required. Field work shall be performed in accordance with the criteria and guidance provided in EM 1110-1- 1804 and the procedures outlined in the applicable ASTM standards (latest edition) for the methods used. When drilling in and near flood embankment dams and levees and/or their earth and rock foundations the Contractor will comply with ER 1110-1-1807.

a. Undisturbed Sample Borings.

(1) General Requirements for Continuous and Intermittent Sampling. Undisturbed sample borings shall be either manually or mechanically driven via industry standard drilling equipment in good working order and shall exhibit properties as close to the in-situ properties as can practically be obtained through use of ASTM sampling methods cited herein. Drilling personnel shall exercise care during the drilling operations to assure that changes in materials are detected and that samples are obtained at start of each new material layer and at the prescribed intervals thereafter according to the sampling methods prescribed herein. Sample containers shall be labeled with project name, location, boring number, sample number, depth of sample, and date sample was obtained.

(2) Continuous Sampling.

(a) Cohesive Materials. Where cohesive materials are encountered, continuous sampling shall be performed in accordance with ASTM D1587, “Standard Practice for Thin-Walled Tube Sampling of Soils for Geotechnical Purposes”, using 3-inch diameter thin-walled tube samplers, or as specified in the task orders. Continuous sampling within cohesive materials using thin-walled tubes shall be performed at the rate of one sample every two (2) feet of depth. As cohesive samples are retrieved, they shall be extruded from sample tubes by a mechanical jack or hydraulic piston designed in a manner to minimize disturbance or distortion of the sample during extrusion. The sample shall be supported during the extruding process and shall be moved from the extruder to the wrapping table by a rigid sample supporting device. Pocket penetrometer tests shall be made on each cohesive undisturbed sample after removing all loose disturbed material from the sample. The tests shall be performed according to the standard procedures using a pocket penetrometer in good working order and having a scale range of

0.25 to 4.5 tons per square foot (tsf) in scale divisions of 0.25 tsf. Where pocket penetrometer results yield 0.25 tsf or less, the Contractor shall also perform a field torvane test using the appropriate torvane attachment for soft materials. For every 2-feet of continuous sampling in cohesive soils, and after removal of loose disturbed material, the remaining intact undisturbed sample shall be a minimum of 1-foot in length to the extent practicable for the consistency of the materials sampled by experience and competent drillers. Cohesive samples shall be wrapped with aluminum foil, placed in containers, to be furnished by the Contractor, and encased and sealed with paraffin or approved equal sample sealing method.

(b) Non-cohesive Materials. Standard Penetration Tests (SPTs) shall be performed in accordance with ASTM D1586, “Standard Test Method for Penetration Test (SPT) and Split- Barrel Sampling of Soils”, where cohesionless materials are encountered (such as sands, clayey sands, silty sands, etc.), at the start of each cohesionless layer and at 5-foot intervals thereafter within the cohesionless layer(s) to the required depth of the boring. For each SPT test, the number of blows required to drive the sampler shall be recorded for every 6 inches driven until driven a full 18 inches to complete the test. The cohesionless materials from the sampler shall be placed in quart jars or approved equal sample container, to be furnished by the Contractor, for follow-up lab testing. Sample jars or other approved containers shall be equipped with moisture tight screw caps or approved sealing method.

(3) Intermittent Sampling. Sampling methods and procedures for intermittent sampling shall be the same as that prescribed for continuous sampling above. Unless otherwise directed, sampling intervals for intermittent sampling shall be as follows:

(a) Cohesive materials. Starting at the ground surface, maintain an interval of one sample every two (2) feet to the 10-foot depth, then below the 10-foot depth, the sampling interval shall be one sample every five (5) feet or change in material type, whichever is less.

(b) Non-Cohesive Materials. If non-cohesive materials are encountered at the surface and/or within the top 10 feet of an intermittent boring, then samples shall be obtained at the surface, then at five (5) intervals thereafter within the non-cohesive layer(s) using the SPT procedure.

b. Disturbed Sample Borings. A disturbed sample boring is any boring advanced with, and samples obtained with, either a manually or mechanically operated auger, in accordance with ASTM D1452, “Standard Practice for Soil Exploration and Sampling by Auger Borings”. Disturbed soil samples shall be obtained at the existing ground surface and at each 5-foot interval thereafter, or change in material type, whichever is the lesser interval, or at the interval required by the task order (not to exceed one every two

(2) feet) to the required depth of the boring. Disturbed soil samples shall be placed in quart jars or approved equal sample container, to be furnished by the Contractor, for follow-up lab testing. Sample jars or other approved containers shall be equipped with moisture tight screw caps or approved sealing method.

Larger grab bag samples may be required for obtaining materials for laboratory compaction tests.

Samples for compaction tests shall consist of bag samples of specified weight that are composed of representative composite samples obtained from designated depths in the boring. In addition to the disturbed samples described above, a jar sample that is representative of the material composing each bag sample shall also be obtained for material identification purposes. All sample containers shall be furnished by the Contractor. Each sample obtained shall be clearly marked or labeled with the project name, location, boring number, sample number, depth of sample, and date the sample was obtained.

c. Vibracore. Vibracore sampling is a specialized method for obtaining continuous samples of unconsolidated soils underwater or on land in relatively soft soils. The sampler uses a vibratory unit to drive a continuous sample tube (or barrel) through the soil and retrieve samples. The vibratory unit may by electric, pneumatic, or hydraulic; however, must be appropriate for the soil conditions and required sampling depths at the vibracore locations. A core retaining device shall be used to ensure full core recovery. The vibracore apparatus shall include a method to evacuate water from the barrel to create a vacuum in the barrel as it penetrates the soil.

12. CONE PENETROMETER TESTS. The CPTs shall be performed at the locations and pushed hydraulically to the depths specified in the task order. CPTs shall be performed in accordance with the requirements outlined in ASTM D5778. Plotted results of each test shall include as a minimum, the depth versus the cone resistance (qc), the depth versus the cone side friction (fsc), the depth versus the pore water pressure, and the depth versus the friction ratio (Rf). Depth versus the soil behavior type using an accepted friction ratio classification chart shall also be provided. Plotted results of cone resistance, cone side friction, and porewater pressure shall be provided in units of tons per square feet (tsf), and depth shall be provided in feet. In addition to plotted results, raw data files from which the plots are based on shall be provided with the final deliverables, with raw data labeled according to type of information and units. The Contractor shall record the coordinates and elevation (X, Y & Z) of CPT locations with reference to the horizontal and vertical datums specified in paragraph

20. SURVEYING EXPLORATION LOCATIONS, or as otherwise specified in the individual task orders. The Contractor shall have experienced and competent personnel and helpers performing the CPT operations at all times.

13. EARTHWORK.

a. Earthmoving Equipment. Earthmoving equipment furnished and utilized by the Contractor shall meet the minimum requirements shown below and be dependable equipment in good condition and of sufficient size to efficiently perform the earthmoving operations in order to support the drilling operations in heavily vegetated areas or challenging terrain and within the approved time period specified for the work. All equipment is subject to approval by the COR prior to the commencement of the required work and shall be maintained in good working condition by the Contractor throughout the drilling operations.

(1) Small Bulldozer. The small bulldozer shall have a minimum net engine or flywheel power rating of 70 horsepower, be furnished with an angle type blade and power operated controls, and have a track width and configuration setup for optimal performance for the type of foundation and terrain at the site specific project location.

(2) Large Bulldozer.

(3) Track-hoe. The track-hoe shall have a minimum net engine or flywheel power rating of 135 horsepower, have a hydraulic system configuration capable of operating up to a 1.8 cubic yard bucket filled with soil, and capable of placing and picking up the matting described below.

The track width and configuration shall be setup for optimal performance for the type of foundation and terrain at the site specific project location.

(4) Matting. Each matt shall be of sufficient size and configuration to support operations of the earth moving equipment, drilling rig, or other vehicle as required. Matting shall be configured to allow earthmoving and drilling equipment to pass over the matting when used to bridge over trenches, small to medium size ditches, small dips, or depressions, soft areas, other challenging locations, or when being used as a base from which to operate the earthmoving equipment in soft areas. Matting shall be configured and capable of being disassembled and reassembled to the extent necessary to allow the matting to be placed or picked up with the track-hoe equipment included herein. Matting shall be of sufficient quantity to allow the track-hoe equipment to operate on the matting while also placing another set of matting to complete the earthwork operations and create access necessary for complete drilling operations.

b. Earthmoving Locations. Locations for which earthmoving equipment will be used will be determined by the Government on a case by case basis for a given site and be included in the task order PWS. In all cases where the use of the small bulldozer, large bulldozer, track-hoe, matting, or some combination thereof is identified for a given task order, the Contractor shall be responsible for notifying the Government of the extent, scope, and locations and will not proceed with the work until the appropriate written approvals and rights of entry have been obtained. Factors which may be the basis for the Government considering the use of the clearing and earthmoving equipment for approved sites may include, but not be limited to, heavily vegetated sites with no pathways, locations where the digging of test pits are requested, or sites with uneven terrain whereby the use of other land based, marsh terrain, or floating plant equipment covered under the main contract will not allow for successfully traversing, accessing, or navigating the investigation site to the specified boring locations.

c. Selection of Equipment. Depending on the extent and nature of the earthwork and clearing, the Government may require any combination of the small bulldozer, large bulldozer, track-hoe, and matting be used, but not necessarily all these items for a given project and will be identified in the task order PWS.

Once a task order is awarded, any deviations from the types or combination of equipment require a modification in advance, otherwise, the use of additional equipment will be at the expense of the Contractor.

d. Equipment Operators and Duration of Operation. The Contractor shall have experienced and thoroughly competent operators performing the earthmoving and clearing operations with equipment specified herein. Costs for qualified operators shall be included in the overall daily rates for using the various types of equipment.

e. Preservation and Restoration. Any earthwork permitted under a given task order shall be done in a manner that is kept to the “bare minimum” necessary to facilitate getting the drilling equipment through to the investigation locations, or facilitate other types of investigations. The Contractor shall exercise care and reasonable judgment in order to ensure any property at the site is not damaged, such as, but not limited to, structures, utilities, pipelines, fences, gates, roads, pathways, landscaped areas, ditches, levees, vehicles, livestock, etc. Property damaged by the Contractor shall be repaired at the Contractor’s expense. Additionally, after the earthwork operations are no longer needed to assist the soil investigations, the Contractor shall restore the soil topography to a condition comparable to the condition before any earthwork at the site began, unless this requirement is specifically waived by the land owner in written documentation.
