HAMMER: Furnish pile driving hammers of a size and type able to deliver consistently effective dynamic energy, suitable to the piles to be driven and to the subgrade material into which they are to be driven, when operating at not less than 75 percent efficiency of the rated driving energy. Unless otherwise indicated, use a hammer with rated driving energy of not less than 15,000 ft.lbs. per blow, nor more than 26, 000 ft.-lbs. per blow. C. DRIVING CAPS: Equip hammer with a driving cap capable of protecting the pile head and providing uniform distribution of hammer energy to the pile head. D. LEADS: Use fixed rigid type pile driver leads that will hold the pile firmly in position and alignment, and in axial alignment with the hammer. Free-swinging leads will not be permitted. Extend leads to within two feet of the elevation at which the pile enters the ground. 4. INSTALLATION A. GEOTECHNICAL REPORT: Refer to the Geotechnical Engineering Report No. W- 5618 prepared by Rittenhouse-Zeman and Associates dated April, 1988 for specific recommendations. 4 PILE FOUNDATIONS Section 02300 B. INSPECTION: Installer must examine the areas and conditions under which timber piles are to be installed and notify the Contractor in writing of conditions detrimental to the proper and timely completion of the work. Do not proceed with the work until unsatisfactory conditions have been corrected in a manner acceptable to the installer. C. Continuously drive each pile at the locations indicated, to the required point elevations and driving resistance established by the driving of test piles. D. Carefully maintain the center of gravity for each group or cluster of piles to conform to the locations shown on the drawings. E. Carefully plumb the leads and the pile before driving. Take care during driving to prevent and to correct any tendency of piles to twist or rotate. F. When handling and driving long piles, take special precautions to ensure against overstress or leading away from a true position when driving. When high- resistant strata lying near the surface must be penetrated, spud piles may be used to minimize hard driving of long piles during the early stages of driving operations. G. Drive piles within the following maximum tolerances: 1) LOCATION: 3" from the location indicated for the center of gravity of each single pile or pile groups: 1" for piles under walls. 2) ALIGNMENT: Maintain 1" in 10 ' -0" from the vertical, or a maximum of 411, measured when the pile is above ground, in the leads. H. DAMAGED OR MISDRIVEN PILES: Damaged piles, and piles driven outside the required driving tolerances, will not be accepted. If practical, withdraw piles rejected after driving, and replace with new piles. Drive additional pile or piles where the center-line deviation exceeds 3" and an analytical determination indicates a load on any pile 5 PILE FOUNDATIONS Section 02300 4 . H. (cont'd) exceeding 110 percent of the design load. Rejected piles may be abandoned and cut-off if removal is impractical and additional piles driven to replace the rejected units as the newly designated locations by the Structural Engineer. Solidly fill spaces that are left by withdrawn piles, that will not be filled by new piles, using cohesionless soil material such as gravel, broken stone, and gravel- sand mixtures. Place and compact throughout the length of the space. I. CUTTING-OFF: All piling shall extend a minimum of 3 ' above grade. final cut-offs will be made by Building Contractor. Re-coat cut-off of piles with two coats of hot creosote, followed with one coat of coal tar pitch. Allow sufficient time between applications to permit absorption of each coat before the succeeding one is applied. J. SPLICES: Splices in timber piles will not be permitted. K. FIELD QUALITY CONTROL: Install a minimum of four test piles in order to verify design pile lengths. Test piles, furnished and driven by Contractor to determine lengths of piles, may be located, cut off, and become part of the foundations system provided they conform to the contract requirements. L. LOAD CAPACITY: The load to be carried by an individual pile shall be determined by the following formula: ENGINEERING NEWS RECORD FORMULA (as applied to diesel and single acting hammers) 2E R S + 0. 1 Where R is the driving resistance and also the calculated safe bearing capacity in pounds. S is the "set" in inches. The set is the distance the pile is driven for each hammer blow during the last six (6) inches of driving. 6 PILE FOUNDATIONS Section 02300 M. MEASUREMENT OF PAYMENT: 1) BASIS FOR BIDS: Bids shall be based on the number of piles indicated, from point to cut-off plus not less than one foot of overlength for cutting piles at the required cut-off elevations. 2) BASIS FOR PAYMENT: From the data obtained as a result of driving piles, the Engineer and Inspector will calculate the actual total new length of piles used in the work. Contract prices per linear foot includes all labor, materials, tools, equipment, and incidentals, and for performing all work for furnishings, driving and cutting off piles. This includes disposal of cut- offs. 3) MEASUREMENTS: Will be based ont he effective length of piles in place, with all fractional lengths measured to the nearest foot. Payment for linear footage in excess of that indicated on the drawings, and credit for linear footage less than that indicated in the drawings, shall be made at the unit prices stated in the Contract and shall be based on net addition or deduction. 4) Test piles that become part of the completed foundation system will be considered as an integral part of the work. 5) No payment will be made for rejected piles, including piles driven out of place, imperfect piles, or piles damaged in driving or handling.
