The Audubon installation team completed this project in just one day. Issues faced during this project were complying with SEPTA and AMTRAK safety training and overhead power lines. The gradient of the hill at this location added a bit more of a challenge also, but Chuck Tauscher stated that the project overall was a great success and gained Audubon experience working near vibration sensitive railroad tracks.
- Helical Pile Type: SS5
- # of Helical Piles: 118
- Location: Delaware County, PA
- Equipment Used: 6″ PVC Cased Grout Columns. 2,000 Ft-LBs of torque were required using a length of 19′-24′. Used a Helical Pulldown Micropile with a max spacing of 10′.
- Challenge/Unique Aspect: Working near an active rail line that could not be shut down during construction, Helicals were the ultimate choice since small equipment and material could be mobilized and de mobilized during construction in accordance with AMTRAK requirements and requests.
