3. PRIMARY DUTIES

This contract contains services for Geotechnical work and HTRW site conditions. Many of the services apply to both Geotechnical and HTRW work; consequently, the written explanations for the duplicate services are the same.

The CLINS for Geotechnical and HTRW work will have the same number designations. The reason for separate

CLINS is due to the cost differences between Geotechnical and HTRW work. Specific requirements for HTRW work include but are not limited to personal safety and refresher courses, specific training requirement for working with HTRW substances, personal protective equipment including respirator if necessary, sampling equipment, monitoring equipment, communication equipment, decontamination requirements for personnel and equipment. For

HTRW sites, before any work/project can begin, the Contractor shall provide to the government representative the names of all contract personnel who will be on site. The Contractor shall provide copies of the contract personnel’s

40-hour or 24-hour Training on HTRW and current 8-hour Refresher course.

4. MOBILIZATION AND DEMOBILIZATION

Mobilization shall consist of the delivery at the site of all plant, equipment, materials, and supplies to be furnished by the Contractor, and the complete assembly of all such plant and equipment, in satisfactory working order.

Demobilization shall consist of the removal from the site of all plant and equipment after completion of the work and cleanup of the site to as near the condition it was in prior to mobilization. Mobilization and demobilization includes but is not limited to delivery and removal of equipment to a work site, daily travel to a work site, per diem, and bridge or toll fees. The Contractor is also solely responsible for security against theft, destruction, and/or vandalism of the Contractor's property and/or equipment. All mobilization and demobilization costs for all equipment including (but not limited to) drill rig, backhoe/trackhoe, televiewers, subcontractors, etc. will be paid using unit price per CLIN 0001. The CLIN will be negotiated per Task Order with separate breakout line item mobilization/demobilization costs per equipment type.

5. DRILL RIG DRILLING HOURS AND SAMPLING PROCEDURES

Drilling hours for Solid Flight-Auger, Hollow Stem-Auger, Mud Rotary, Air Rotary, ODEX, ARCH, Sonic, and

Diamond Rock Core will be paid using unit price per CLINs 0002A through 0002H. Cone Penetrometer Testing will be paid using unit price per CLINs 0002J and 0002K. Direct push drilling will be paid using unit price per CLINs

0002L through 0002N. Specialty drilling will be paid using unit price per CLINs 0002P and 0002Q. To simplify the future task orders, CLINs are no longer specific to Geotechnical or HTRW projects and standby time is grouped by drilling method. A general description for each type of drilling, sampling, and special requirements is described in the following sections.

5.1 Hollow Stem-Auger, Mud Rotary, Air Rotary, ODEX, and ARCH:

The Contractor shall provide equipment capable of soil drilling and sampling to a depth of 150 feet with Hollow

Stem-Augers and/or Mud Rotary methods and 300 feet with 6-inch nominal diameter or greater ODEX, down hole casing advance, or other percussion drilling systems. For any Task Order, the Contractor shall have on hand equipment and material to allow drilling to 30 feet greater than the maximum depth required by the Task

Order, or 30 percent in excess of the maximum depth when the depth is 100 feet or greater. Augers shall be nominal 6-inch or 8-inch O.D. Hollow Stem flight auger with a minimum I.D. (inside diameter) of 3-1/4 inches.

CLINS 0002A through 0002C are intended for exploration and sampling activities. Drilling methods used to drill advance borings for the installation of monitoring wells, piezometers, or inclinometers are included under

CLINs 0007A through 0007D. Soil drilling and sampling by rotary methods will be paid at the unit price per

CLIN 0002A (Solid-Flight Auger and Hollow Stem Auger), CLIN 0002B (Mud Rotary), and CLIN 0002C

(Air Rotary/ODEX/ARCH), as described in the pricing schedule.

5.1.1 Standard Penetration Tests and Disturbed Samples:

Standard penetration tests (SPTs) shall be performed in accordance with ASTM D 1586-11 at the depth intervals prescribed in each individual Task Order. No standard penetration test shall bottom within 0.5 feet of a potential undisturbed sample zone. If no sample is retrieved at the specified interval, another sample will be taken immediately below or at a location specified to achieve representative sample material by the on-site Government Representative. The split-barrel samplers used for standard penetration tests shall be

2.0-inch O.D., 1.375-inch I.D.; 18- or 24-inches split section length and shall conform to ASTM D 1586-

11. If refusal is encountered during drilling or sampling, an attempt shall be made to identify the type and occurrence (bedrock, boulder, etc.) of the material. A disturbed sample shall be taken from each split-barrel sample and double bagged in plastic zip-lock type bags and properly labeled. Labels shall be clearly legible and be printed in indelible ink on the bag label, the sack, and the shipment boxes. Labels shall include, but are not limited to, the installation designation (i.e. base or project), project name, hole number, sample depth, date collected, type of sample, and sampler’s initials. If a change of material is encountered in any split-barrel sampler, it will be noted on the drill logs and bagged separately.

5.1.2 Three-Inch and 2.5-Inch Split-Barrel Sampling:

Three-inch O.D. and two and a half inch O.D. split barrel samples, where ordered, shall be driven up to 24 inches, in a fashion identical to that used for standard penetration tests. A 300-pound hammer may be used if approved by the Government prior to use. Blow counts shall be recorded for the entire drive with the type of hammer and the drive intervals noted on the drill log. Samples shall be retained from each split-barrel as directed by each individual Task Order. The split-barrel samplers used for larger sized penetration tests shall be 3.0-inch O.D. or 2.5-inch O.D.; 18- or 24-inches split section length and shall conform to ASTM D

1586-11. Automatic trip type hammers are required. The hammer shall deliver the equivalent energy of a

140 lb. weight experiencing a 30-inch free fall. Drill rods used for standard penetration tests shall be AWJ size or larger.

5.1.3 Standard Penetration Tests and Undisturbed Samples:

Every effort shall be made to assure a clean hole for standard penetration tests and undisturbed sampling.

Casing, if used, shall not be driven deeper than 1-foot above the depth of the next standard penetration test.

If using drilling fluid, the fluid shall be circulated long enough to assure a clean hole. Between penetration tests, bit pressure and rate of penetration shall be noted and recorded on the log. If refusal is encountered during drilling or sampling, an attempt shall be made to identify the material-causing refusal as to its type and occurrence (bedrock, limestone, boulder, granite, etc.). This information shall be recorded on the drill log. At all times during rotary drilling, drill fluid shall be maintained at the top of the hole. If heaving of the hole bottom occurs and the addition of water does not improve hole stability sufficiently, a weighted drill fluid shall be used, with density not to exceed 12 lbs/gallon. Other drilling procedures may be specified on an individual Task Order.

5.1.4 Mud Tanks:

For mud rotary drilling, the Contractor shall have available, or have ready access to, drilling fluids, such as bentonite; natural organic polymers, and a drill mud weighted with barite in case of artesian conditions, or flowing or heaving sands are encountered while drilling. These supplies shall be considered incidental to the drilling costs. The Contractor shall have a portable mud tank of a least 175-gallon capacity. Mud pits shall not be excavated into the ground without approval by the Government prior to use.

5.1.5 Drill Bits:

The Contractor shall have side or upwards discharge bits (when mud-rotary drilling is utilized) for use in zones of testing and sampling. The Contractor shall also have tri- cone roller-rock bits available for possible use if cobbles or boulders are encountered. The drill bits will be considered incidental to the drilling costs.

5.1.6 Procedures for Rotary Drilling on Embankments:

Procedures for drilling through embankments will be specified in the individual Task Orders. Unless otherwise specified, the use of drilling fluids (water or air) is not permitted when drilling through embankments, including dams and levees. ER 1110-1-1807 shall be adhered to during all phases of each

Task Order executed.

5.2 Standby Time for Rotary Drilling:

Standby time shall be any time that rotary drilling activities are delayed for the convenience of the Government at the request of the Government Representative. It is not to be used for Contractor caused delays due to inadequate personnel, equipment malfunctions, or adverse weather conditions. The standby time for the rotary drill rig will be paid at the unit price per CLIN 0002D as described in the pricing schedule.

Costs are to include all materials and labor needed to complete the grouting process, and cleanup if needed. It is emphasized that payment for drilling hours will not include drill rig usage during the grouting phase. Holes will normally be grouted immediately upon completion of drilling, but should it be necessary to temporarily leave the hole open, it will be required that the hole be covered with a minimum of 1/2 – inch thick plywood sheet or steel hole cover and traffic cones. After grouting, the hole will normally be allowed to settle overnight, topped with grout the following day, then filled with soil cuttings, tamped, and covered with concrete or asphalt patch if required. The Contractor shall ensure that all holes are backfilled with grout prior to leaving the site.

8.1.1 Bentonite-Cement Grout:

Per EM 1110-2-3506, the grout mixture should be composed of approximately 4 to 7 percent bentonite and

93 to 96 percent Portland cement. Water used for sealing mixtures shall be clean and of potable quality.

Some sites may require a slightly different grout formula based upon local regulatory requirements. In those cases the mix will be as specified in the individual Task Order.

8.1.2 Grout Mixing:

Grout mixing shall be done thoroughly by mixing with a paddle-type mechanical mixer, high shear mixer, or recirculating through a pump to ensure that the mixture is uniform and there are no lumps.

8.2 Grouting Inspections:

Some counties require “Grouting Permits” and inspections during the grout phase. The Contractor will be responsible for obtaining all permits and for coordinating inspection times with the appropriate County Grout

Inspector, per section 22.

8.3 Cementing and Drilling Out Cement, HQ:

All weathered core loss zones and broken rock zones that interfere with drilling operations or result in substantial loss of drill water return, as determined by the Government Representative, shall be cemented when and as directed with quick setting cement. Generally, cementing of such zones will be directed when the bottom of the broken zone is reached or at a maximum of five feet of drilling after the water loss. When directed by the

Government Representative, minor quantities of overfill and redrilling of two to five feet above the water loss zone will be allowed and paid for to prevent excessive water takes in fractures and cavities. When not directed, it shall be at the Contractor’s expense. Each time before cementing, the hole shall be pressure tested. After cement has set sufficiently, the hole shall be drilled out and coring continued. The cost of drilling out cement will be paid for as a linear foot measurement at the unit price per CLIN 0006A for HQ to smaller diameter core and CLIN 0006B for larger than HQ diameter core.

9.2 Shelby Tube Undisturbed Samples:

Undisturbed samples, when ordered, shall be taken with a Shelby Tube pushed a distance of 24 inches utilizing the drill rig hydraulic system. Undisturbed sampling equipment shall consist of 3-inch, 5-inch, and 6-inch nominal diameter, thin-walled galvanized steel Shelby Tubes. Tubes shall be new and rust-free with smooth interiors and at least 2.5 feet long. Tubes shall be in accordance with ASTM D 1587-15. Piston type samplers may be required in soft or sensitive materials. The Contractor shall have all attachments in order to push the tube in a vertical position. Standard penetration tests shall not be performed at the undisturbed sampling depths.

Thin-walled tube, undisturbed sampling shall be performed in accordance with ASTM D 1587-15, except that the sampling tubes shall be pushed rather than driven. All undisturbed samples will be sealed in the tube with microcrystalline wax (bee’s wax), end capped, and taped with duct or electrical tape. Samples retained in this fashion shall have at least 1.0 foot of recovered material and no obvious damage to the tube (e.g. crimped ends, deflections, etc.) in order to be considered undisturbed. With the tubes sealed with wax, capped, and taped, the outside of the tube shall be wiped clean and properly labeled. This label shall be clearly legible and be printed in indelible ink or paint pen on the outside of the tube. The label shall include, but is not limited to, the installation designation (i.e. base or project), project name, hole number, sample depth, date collected, type of sample, sample designation, sampler’s initials, and “up” orientation. End caps shall be placed on both ends of the tube and wrapped with duct or electrical tape. Samples collected in this manner shall be shipped to the designated laboratory or storage facility in an appropriate shipping crate. Shipment of undisturbed samples shall be done in such a fashion as to minimize opportunities for disturbance and, in cold weather conditions, the prevention of sample freezing. Shelby Tubes will be paid at the unit price per CLIN 0007B as described in the pricing schedule.

9.3 Pitcher Barrel Undisturbed Samples:

When an undisturbed sample is required and Shelby Tubes are not feasible, Pitcher Barrel drilling using Pitcher

Tubes will suffice. Pitcher Tubes are attached to the Pitcher Barrel using Allen set screws, two each. The tube sits in front of the Pitcher Barrel, is spring loaded, and when pressure is placed on the tube, it will slide up inside the Pitcher Barrel. The barrel has hard-faced cutting teeth on the drill bit. The teeth cut the formation, which goes inside the tube.
