A project in Washington D.C. required a deep foundation to support a manhole as well as a section of sewer pipe. Four timber piles were originally specified for the job, but due to time and mobilization constraints, helical piles were substituted due to ease of installation and quicker, easier mobilization.
- Helical Pile Type: 3.5″ (.300 wall) Pipe Piles
- # of Helical Piles: 4
- Location: Washington, DC
- Installation Depth: 35′
- Equipment Used: ICE Drive Head, Digital torque Indicator
- Challenge/Unique Aspect: The helical piles were installed, cut, capped and a concrete foundation poured in the time allotted to just drive the timber piles. Small equipment and the speed and ease of installation reduced lane closures and eased traffic concerns.
