PART 3 EXECUTION

3.1 INSTALLATION

3.1.1 Pile Driving Equipment

Pile driving equipment shall meet the following requirements.

3.1.1.1 Pile Driving Hammers

Pile driving hammers shall be steam, air or diesel drip, single-action, double-acting, differential-acting, or vibratorytype. The size or capacity of hammers shall be as recommended by the manufacturer for the pile weights and solid formation to be penetrated. The pile hammer shall be of sufficient weight and energy to install the specified pile without damage into the soils as indicated. The maximum driving energy of hammers shall be 18,500 foot-pounds for piles for any length. Test piles shall be driven with the same size and type hammer, operating with the same effective energy and efficiency as that to be used in driving job piles. Diesel powered hammers shall be operated at the rate recommended by the manufacturer throughout the entire driving period. Sufficient pressure shall be maintained at the hammer so that:

a. For double-acting hammers, the number of blows per minute during and at the completion of driving of a pile is equal approximately to that at which the hammer is rated;

b. For single-acting hammers, there is a full upward stroke of the ram;

and,

c. For differential-type hammers, there is a slight rise of the hammer base during each upward stroke.

3.1.1.2 Operating Speed

Provide sufficient compressor capacity at all times to maintain the rated speed of hammer during the full time of driving a pile. Maintain the valve mechanism and other parts of the hammer in first class condition so that the length of stroke, for a single acting hammer, and the number of blows per minute, for a double acting hammer, for which the hammer is designed, will be obtained. Any double acting hammer not operating at the rated hammer speed specified in the manufacturer's catalogue, for the particular hammer being used, shall be deemed unsatisfactory and shall be removed from the site.

3.1.1.3 Diesel Hammers

Provide all diesel hammers with an acceptable means of measuring hammer energy. When pressure gages are included as normal equipment, furnish and maintain them in operable condition. Submit hammer manufacturer's charts and graphs that are required to calibrate hammer energy. Arrange easy access to the pressure gages so the Contracting Officer may conveniently take readings at the site.

3.1.1.4 Leads

Leads are required and shall be fixed at the top and adjustable at the bottom. Swinging leads may be allowed if site conditions merit their use and are approved or if a driving template is provided.

3.1.1.5 Driving Cap or Helmet and Cushion Block

Driving cap or helmet shall be an approved design and shall be capable of protecting pile heads, minimizing energy absorption, and transmitting hammer energy uniformly and consistently to piles. Place driving helmet or cap and cushion block combination between top of pile and the ram. Driving cap shall fit snugly on the top of piles and shall employ a cushion block to prevent impact damage to piles. The cushion block may be a solid or laminated softwood block with the grain parallel to the pile axis and enclosed in a close-fitting steel housing. The thickness of the block shall be suitable for the length of pile to be driven and the character of subsurface material to be encountered. If block is damaged, split, highly compressed, charred or burned, or has become spongy or deteriorated, replace with new block at no additional cost to the Government. Under no circumstances will the use of small wood blocks, wood chips, rope or other material permitting excessive loss of hammer energy be permitted.

3.1.1.6 Pile Collars and Shoes

Collars or bands for protecting pile butts against splitting, brooming, and other damage while being driven shall be of an approved design. Shoes shall be fitted to protect pile tips from damage during driving. Provide as indicated in Table 1.

3.1.2 Piles

Inspect piles when in the leads immediately before driving. Cut piles at specified cutoff elevation with pneumatic tools by sawing or other approved method. Where cutoff is below existing ground surface, complete excavation, sheeting, and dewatering, if elected, before pile is driven to cutoff elevation.

3.1.2.1 Driving Piles

When driving long piles of high slenderness ratio, special precautions shall be taken to ensure against overstressing and leading away from a plumb position. During driving, pile driving hammers shall be operated at all times at the rate and conditions recommended by the hammer manufacturer. Each pile shall be driven continuously and without interruption until the required depth of penetration and penetration rate per blow have been attained.

Piles shall be driven to the full penetration required where practicable to do so without damage to the piles. If found impracticable to drive any pile to the depth required, such pile shall be cut off and abandoned or pulled as directed. Driven piles which have a penetration of less than indicated and have not been driven to the established maximum penetration per blow are unsatisfactory. Driving of piles beyond the point of refusal defined as 5 blows per 1/4 inch or as indicated by excessive bonding of the hammer or kicking of the pile shall not be attempted. Piles which have uplifted after driving shall be be redriven to grade after conclusion of driving in that general area.

When the penetration per blow of any pile during the final blows exceeds that permitted or it is found that a pile is not of sufficient length to give the capacity specified, and the pile has been driven to its full length, the Contractor shall pull the pile and furnish and drive a longer pile or take other corrective measures as directed by the Contracting Officer. The use of followers or splices shall not be permitted except where specially authorized by the Contracting Officer.

After driving is completed, all piles shall be "headed" or cut off normal at the cutoff elevation. Headed treated piles, shall be given two heavy coats of preservative, followed by the application of a heavy coat of coal-tar pitch. Piles driven in locations where they are constantly subject to water spray shall be given this treatment immediately after they are cut off and before the cutoff surface has been wetted. Cutoffs shall become the property of the Contractor and shall be removed at no additional cost to the Government.

3.1.2.2 Test Piles

Provide 15 test piles conforming to the same requirements as specified for job piles. Contractor shall prepare and submit a Test Pile Plan indicating the location of the proposed test piles and the load testing schedule for the test pile. The plan shall include a minimum of two (2) representative test piles for each outfall facility, one (1) at a landside location and one (1) at a waterside location, for each accepted pile driving method, jetting, spudding, or predrilling (as approved by contracting office and the project design engineer).

Test piles shall be driven in the same manner as specified for job piles.

Record driving data as specified in paragraph entitled "Job Pile Driving Records." Confirmation of the assumed allowable working loads of single piles shall be made by static loading and measuring each test pile in the manner described below. Test piles indicated or directed to be driven in permanent locations may be incorporated into the work if, after satisfactory completion of the load test, they are approved for inclusion in the work by the Contracting Officer. Every facility shall be provided by the Contractor for the Contracting Officer to inspect and measure the deflection or settlement of the pile under test. Furnishing of measuring equipment and making measurements of deflection or settlement will be the responsibility of the Contractor.

3.1.2.3 Load Tests

Perform load tests on 15 test piles in accordance with ASTM D3689, Standard Test Methods for Deep Foundations Under Static Axial Tensile Load. Perform load tests at locations as directed. Provide testing and measuring equipment, perform loading, and provide observation facilities for a registered professional engineer employed by the Contractor to inspect and record settlement and deflection of piles under test loads. Do not mobilize load test equipment until directed. Loading frames and equipment shall be ready to place in operation as soon as a test pile has been driven. The maximum tension load to be applied during the test shall be 30 tons. The maximum test load shall be maintained for not less than 24 hours and then unloaded in accordance with ASTM D3689.

3.1.2.4 Tolerances in Driving Bearing Piles

Piles shall be accurately placed plumb and in the correct location both laterally and longitudinally. At the cutoff elevation, butts shall be within 4 inches laterally of the location indicated. Manipulation of piles is prohibited. A variation of not more than 0.25 inch per foot of pile length from plumb will be permitted. Redesign of pile caps or additional work required due to improper location of piles will be the responsibility of the Contractor. Inspect piles for heave. Piles shall be driven to the depths shown and capacities specified. Redrive heaved piles to the required tip elevation. Remove and replace with new piles those damaged, misplaced, driven below the design cutoff, or driven out of alignment, or provide additional piles, driven as directed at no additional cost to the

Government.

3.1.2.5 Job Piles Driving Records

A complete and accurate record of the driving of piles shall be compiled by the Contractor for submission to the Contracting Officer. Indicate pile location, deviations from design location, diameter, original length, installed length, ground surface, tip elevation, cutoff elevation, penetration in blows per foot for the full length of all job piles, hammer data including rate of operation, make, and size, and unusual pile behavior or circumstances experienced during driving such as redriving, heaving, weaving, obstructions, spudding, predrilling, and unanticipated interruptions. Make pile driving records available to the Contracting Officer at the job site, within 24 hours after each day of pile driving.

Include in the construction records the wood species, preservative type, retention, and producer of installed treated timber.

The elevation at the top of the pile shall be measured and recorded by a New Jersey Professional Licensed Surveyor after completion of driving.

3.1.2.6 Lengths of Job Piles

The Contractor shall determine the actual lengths of piles required to be driven below cutoff elevation for the various locations in the work. The Contractor shall determine the number of overlength piles, if any, to be ordered to provide for variations in subsurface conditions. The Contractor may drive as many indicator piles as he considers necessary at no additional cost to the Government. Contractor should understand that this would been done solely for Contractor's own information and to ascertain the approximate length required for each pile to reach the required bearing capacity. Indicator piles may be driven at the same location as required for the design piles as shown in the Contract Drawings, provided they satisfy the Contract requirements as to exact location, minimum embedment, bearing capacity, etc. as specified herein. Indicator piles that are not driven at the required locations and/or do not satisfy any other requirements as specified, shall be pulled out completely and disposed of properly off site at no additional cost to the Government. To provide for "heading" or cutting off normal after driving, piles shall be furnished in lengths at least one foot greater than the minimum lengths specified in paragraph 2.1.1, including Table 1.

3.1.2.7 Framing Treated Piles

Treated piles shall not be cut to permit fitting of timbers except as indicated or specified. Piles of uniform size shall be selected for each bent. If necessary, treated filler blocks shall be used to fill out between piles and bracing. Holes for drift bolts in the tops of piles shall be drilled to a depth of 3 inches less than the penetration of drift bolts in the piles. Drill holes for drift bolts 1/8 inch smaller than bolt diameter. Drill holes for through bolts 1/16 inch larger than diameter of bolt shank. Dap piles to receive straps where indicated. Holes drilled into piles shall be filled with and daps shall be coated with the same preservative used to treat the piles in accordance with AWPA M4. When holes are not used for bolts they shall be tightly closed by a treated plug.

Holes shall not be drilled or spikes shall not be driven into piles to support scaffolding.

3.1.3 Fastening

Use washers of the size and type specified under bolt heads and nuts which would otherwise come in contact with wood.
