Validating the use of screwed vs. driven pipe piles on the Gordondale Satellites.

Validating the use of screwed vs. driven pipe piles on the Gordondale Satellites.
  • The majority of the piles are screw piles which are fast and efficient to install under good ground conditions. A few piles required being driven, but Precision was able to arrange for the pile install contractor to provide a rig that could install both types of piles.
  • There were some unfavorable ground conditions resulting in the inability to install the screw piles to proper depth without damaging them. Due to the fact that we had proactively validated both pile designs, we were able to revert to a steel driven design we had completed for the standard satellite installation design without delays to the piling contractor. They were able to continue installing screw piles in the areas where the ground permitted while the contractor mobilized the necessary driven piles to site. The remainder of the project was completed with steel driven piles and the project schedule was maintained.
