Do It Right! Lessons from the field not to be repeated

Piling

Piling
  • The excavation for this footing is a little
    too steep.
  • When they drove pile here, the bank was still frozen, but now sand slides are taking place.
Piling
  • Be extremely careful when driving pile next to fiber optic.
Piling
  • When filling C.I.P. pile with concrete, fill all the way up.
  • It can be difficult and time-consuming to remove all the material (dirt, rocks, mud, water) that might fall into the pile prior to casting them in concrete.
Piling
  • I've got nothing against Canada, but if you're working on a job funded by state or federal money, you’ve got to use U.S. Steel!
Piling
  • Make sure you’ve got all the required
    paperwork for your piling (mill test reports
    and mill shipping papers, in accordance
    with 3371 and 3372) prior to driving any
    pile on your project.
  • Make sure it’s “Melted & Manufactured in USA” if using state or federal money on your project.
Piling
  • Remember, don’t pour concrete in areas where vibration is present.
  • I would recommend the piling operation below be suspended within an hour of the start of the pour if the forms are vibrating.
Piling
  • Be careful driving pile when working by fiber optic lines.
Piling
  • Example of how to document the use of MnDOT-owned piling.
Piling
  • Don’t weld onto galvanized steel, it has to be ground off first, and make sure it gets hot stick galvanized to repair the damage.
Piling
  • Store welding rods in an airtight container.
