PART 3 EXECUTION

3.1 INSTALLATION

3.1.1 Pile Driving Equipment

Pile driving equipment must meet the following requirements.

3.1.1.1 Pile Driving Hammers

Pile driving hammers must be steam, air or diesel, single-action, double-acting, differential-acting type. The size or capacity of hammers must be as recommended by the manufacturer for the pile weights and solid formation to be penetrated. The pile hammer must be of sufficient weight and energy to install the specified pile without damage into the soils expected to be encountered.

3.1.1.2 Leads

Leads are required and must be fixed at the top and adjustable at the bottom. Swinging leads will not be permitted.

3.1.1.3 Driving Cap or Helmet and Cushion Block

Driving cap or helmet must be an approved design and must be capable of protecting pile heads, minimizing energy absorption, and transmitting

SECTION 31 62 19.13 Page 4 Amendment 0002 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 must fit snugly on the top of piles and must 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 must 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. Under no circumstances will the use of small wood blocks, wood chips, rope, or other material permitting excessive loss of hammer energy be permitted.

3.1.1.4 Pile Collars

Collars or bands for protecting pile butts against splitting, brooming, and other damage while being driven must be of an approved design.

3.1.2 Pile Installation

3.1.2.1 Driving Piles

A complete and accurate record of the driving of piles must be compiled by the Contractor for submission to the Contracting Officer. When driving long piles of high slenderness ratio, special precautions must be taken to ensure against overstressing and leading away from a plumb or true position. During driving, pile driving hammers must be operated at all times at the rate and conditions recommended by the hammer manufacturer.

Each pile must be driven continuously and without interruption until the required depth of penetration has been attained. Deviation from this procedure will be permitted only in case the driving is stopped by causes which reasonably could not have been anticipated. Piles must 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 must be pulled. Piles which have uplifted after driving must be redriven to grade after conclusion of driving in that general area. After driving is completed, fender piles must have tops beveled outboard and be capped.

3.1.2.2 Tolerances in Driving Piles

Piles must be accurately placed in the correct location and alignments both laterally and longitudinally and to the vertical lines. At cutoff elevation, butts must be within 4 inches laterally of the location indicated. A variation of not more than 0.25 inch per foot of pile length from the vertical for plumb piles will be permitted. Inspect piles for heave. 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 at no additional cost to the Government.

3.1.2.3 Pile Driving Records

Keep a complete and accurate driving record of each pile driven. Indicate pile location, deviations from design location, diameter, original length, mudline elevation, tip elevation, cutoff elevation, penetration in blows per foot for the last 10 feet, hammer data including rate of operation, make, and size, and unusual pile behavior or circumstances experienced during driving such as redriving, heaving, weaving, obstructions, and

SECTION 31 62 19.13 Page 5 Amendment 0002 unanticipated interruptions. Make pile driving records available to the Contracting Officer at the job site, a minimum of 24 hours after each day of pile driving. Include in the construction records the wood species, preservative type, retention, and producer of installed pile.

3.2 PROTECTION

3.2.1 Protection of Piles

Square the heads and tips of piles to the driving axis. Laterally support piles during driving, but do not unduly restrain piles from rotation in the leads. Handle, protect, and field treat piles in accordance with

AWPA M4.

3.2.1.1 Damaged Piles

Driving of piles must not subject them to damage. Piles which are damaged, split, broomed, or broken by reason of internal defects or by improper driving below cutoff elevation so as to impair them for the purpose intended must be removed and replaced. Minor damaged areas of treated piles must be field treated in accordance with AWPA M4.

3.3 FIELD QUALITY CONTROL

3.3.1 Inspections

When Government inspections result in product rejection, the Contractor must promptly segregate and remove rejected material from the premises.

The Government may also charge the Contractor an additional cost of inspection or test when prior rejection makes reinspection or retest necessary.
