NOTES:

  1. Refer to Pile Properties for definitions of high and low prestress levels.
  2. For cases 1 & 2, do not allow pile tip to bear on other piling stored in a lower layer.
  3. For cases 3 & 4, tilt the pile in the air, do not allow the pile to touch the ground.
  4. The minimum angle between the pile and the lifting strap is 60 degrees when the pile is in the horizontal position.
  5. The contractor is cautioned that storing piling without regard for proper bunking will result in breakage due to "highcentering" or other stress due to unplanned, incorrect support points.
  6. Dragging a prestressed concrete pile across the ground into the leads may overstress the pile by impacts greater than those assumed in the preparation of these guidelines.
  7. These guidelines do not apply to piling of a different size than shown, or to piling produced by other fabricators.
  8. Solid end plugs in hollow piles, and driving tips on solid or hollow piles, will decrease the maximum lengths shown in the tables.
  9. Concrete strength during field handling is assumed to be 6000 psi.
  10. Impact on the dead weight of the pile is assumed to be 50%.
  11. Tensile stress in the pile during field handling is limited to 3c  or 232 psi.
