Provide at least two levels of support. Templates shall not move when supporting sheet piling. Fit templates with wood blocking to bear against the web of each sheet pile and hold the sheet pile at the design location alignment. Provide outer template straps or other restraints as necessary to prevent the sheets from warping or wandering from the alignment. Mark template for the location of the leading edge of each alternate sheet pile. If in view, also mark the second level to assure that the piles are vertical and in position. If two guide marks cannot be seen, other means must be used to keep the sheet pile vertical along its leading edge.

Pile Driving: Maintain piling vertical during driving. Drive piles in such a manner as to prevent damage to the piles and to provide a continuous closure. Incrementally sequence driving of individual piles such that the tip of any sheet pile shall not be more than 4 feet below that of any adjacent sheet pile. When the penetration resistance exceeds five blows per inch, the tip of any sheet pile shall not be more than 2 feet below any adjacent sheet pile.

Jetting of Piles: Jetting will not be permitted.

Pre-Augering or Spudding of Piles: Pre-augering or spudding of piles will not be permitted.

Cutting and Splicing: Piles driven to refusal or the point where additional penetration cannot be attained and are extending above the required top elevation in excess of the specified tolerance shall be cut off to the required elevation. Piles driven below the required top elevation and piles damaged by driving and cut off to permit further driving shall be extended as required to reach the top elevation by splicing when directed by the Contracting Officer’s Technical Representative. Splice piles as required to drive them to depths greater than shown on the drawings and extend them up to the required top elevation. If splices are required in adjoining piles the splices must be spaced at least 2 feet apart in elevation. Welding of splices shall conform to the requirements of AWS D1.1. Ends of piles to be spliced shall be squared before splicing to eliminate dips or camber. Splice piles with concentric alignment of the interlocks so that there are no discontinuities, dips or camber at the abutting interlocks. Spliced piles shall be free sliding and able to obtain the maximum swing with contiguous piles. Trim the tops of piles excessively battered during driving, when directed at no cost. Pile cut-offs shall become the property of the Contractor and shall be removed from the site. Use a straight edge in cutting by burning to avoid abrupt nicks. Holes shall be drilled or burned and reamed by approved methods which will not damage surrounding metal. Do not use explosives for cutting.

Welding: Shop and field welding, qualification of welding procedures, welders, and welding operators shall be in accordance with AWS D1.1.

Tolerances in Driving: Drive all piles with a variation from vertical of not more than 1/4 inch per foot. Place the pile so the face will not be more than 6 inches from vertical alignment at any point. Top of pile at elevation of cut-off shall be within ½ inch horizontally and 1 inch vertically of the location indicated. Manipulation of piles to force them into position will not be permitted. Check all piles for heave. Redrive all heaved piles to the required tip elevation.

Inspection: Perform continuous inspection during pile driving. Inspect all piles for compliance with tolerance requirements. Bring any unusual problems which may occur to the attention of the Contracting Officer’s Technical Representative.

Inspection of Driven Piling: The Contractor shall inspect the interlocks of the portion of driven piles that extend above mudline. Remove and replace piles found to be out of interlock.

Installation Records: Maintain a pile driving record for each sheet pile. Indicate on the installation record installation dates and times, type and size of hammer, rate of operation, total driving time, dimensions of driving helmet and cap used, blows required per foot for each foot of penetration, final driving resistance in blows for final 6 inches, pile locations, tip elevations, ground elevations, cut-off elevations, and any reheading, cutting or splicing of piles. Record any unusual pile driving problems during driving. Submit complete records to the Contracting Officer within 10 days after completion of driving.

16. PART 3 EXECUTION

Installation Driving Piles: Operate hammer at manufacturer's rated speed, and drive pile without interruption to the indicated depth. Drive piles with the same hammer, cushion, or cap block. If the piles are not of sufficient length to give the capacity specified, notify the Contracting Officer’s Technical Representative, who will determine the procedure to be followed. Jetting of piles is not permitted.

Driving Equipment: Use an air-, steam-, or diesel-powered pile hammer with a capacity at least equal to the hammer manufacturer's recommendation for the total weight of pile and character of subsurface material to be encountered. Minimum driving energy shall be not less than 15,000 foot-pounds. Driving energy shall be obtained by use of a heavy ram and a short stroke with low impact velocity. Position a pile cap or drive cap between the pile and hammer. Place hammer cushion or cap block between ram and the pile cap or drive cap. Hammer cushion or cap block shall have consistent elastic properties, minimize energy absorption, and transmit hammer energy uniformly during while driving.

Tolerances In Driving: At cutoff elevation, butts shall be within two inches of the location indicated. Manipulation to move piles into position will be permitted only within the tolerance to return the pile to the design location. Attain a variation less than 0.25 inch per foot of pile length from the vertical of pile length.

Splices: When approved, provide splices of the full penetration butt weld type in accordance with AWS D1.1 or proprietary prefabricated sleeves. Use only one splice per length of pile.

Records: Keep a complete and accurate record of each pile driven. Records shall indicate pile locations, deviations from design locations, original length, ground elevation, tip elevation and cutoff elevation. Include penetration in blows per foot for the entire length of pile, hammer operation data and unusual pile behavior or circumstances experienced -- End of Section --
