02520.10 1115 Section 02520 - Steel Piles
Description
02520.00Scope - This Section includes the requirements for steel pipe, steel H -beams, and steel
sheets used for piling.
Materials
02520.10Steel Piles:
sweep specified in AASHTO M 160 ( ASTM A6).
shall be constant in section. Steel piles shall conform to ASTM A252 or API 5L and the grade shown.
Steel shall conform to the requirements of ASTM A36 or ASTM A572,. The manufacturer's name, brand or trademark may be shown by die stamping in the web at intervals not exceeding 20 feet along the length of the pile.
points or any other proprietary steel pile tip reinforcement. Legibly m ark or tag each cast steel point or shoe delivered to the Project Site with the heat or lot number. Submit certified mill test reports showing the physical and chemical properties of each heat or lot number. If the heat or lot number cannot be read on the point or if the mark or tag is missing, the point or shoe will be rejected.
Provide reinforced tips for steel H -piles from the QPL. In addition, all cast steel points or shoes shall conform to the following:
ASTM A27, Grade 65 - 35 ASTM A27, Grade 70 - 36 ASTM A27, Grade 70 - 40 ASTM A148, all grades
For steel H -piles provide no less than a 5/16 inch fillet weld full width of each flange.
or lot number, at lea st one pile tip or up to 10 percent of the tips for larger projects, of the pile tips delivered for incorporation into the Project .
The selected tips shall be tested as follows:
• Grind five smooth spots on each randomly selected tip. The Engineer will te st each smooth spot on each tip with a portable hardness tester or in a laboratory. If three or more of the five spots tested have a reading below 74 on the "B" scale, the tested tip and the entire lot shall be rejected. • For steel H -piles, determine the w eight of the tips. Each cast steel H -pile point shall have a weight not less than 30 percent of the weight of a 1 foot section of the H -pile to which it will 02520.30 1116 be attached. If any of the tested tips fail to pass the minimum weight criteria the entire lot shall be rejected.
Pile tips that are supplied unattached to the pile may be selected for nondestructive testing as described above. Pile tips passing the field test may be incorporated into the Project . Pile tips selected for testing that are supplied already attached to the pile will be destructively tested as determined by the Engineer. Provide replacement tips for the tips that are destructively tested at no cost to the Agency. Replace rejected tips with new tips and rejected lots with new lots at no additional cost t o the Agency. No time extension or other compensation will be granted for Materials or Work required in testing pile tips, replacing rejected pile tips or for replacing tips that are destructively tested. New tips and new lots may also be tested.
02520. 30 Acceptance - Material for piles will be accepted according to 00165.35 and this Section.
