Q

Can the test be performed if there is only a single center reinforcing bar installed in a Continuous Flight Auger (CFA) pile or Augered Cast-in-Place (ACIP) pile?

A

A test using a single Thermal Wire cable can be used to assess small diameter shafts (or augercast piles) where a single central bar is used for reinforcement. The optimal time of testing decreases as the diameter decreases where the peak temperature may occur only a few hours after placement. Due to this short window of time, and the difficulty to install access tubes, Thermal Wire® cables are required for this application.
