We placed two to four crews on this project at any given time, and extensively utilized our jack-up barge to drill borings in the potomac that would be too dangerous for a standard spud barge.

DC Water - Clean Rivers Tunnel

SPT, Marine, Vacuum Excavations and In-Situ Testing

We utilized our jack up barge, which allowed us to drill deep borings over the course of multiple days without worrying about tidal flucuations affecting the quality or accuracy of the data we collect. Moreover we handled coordination with the pier owners to coordinate drilling operations in a way that minimized disruption to inbound vessels.

Statement While we had traditionally only performed CPT testing on non-pavement surfaces, where we could anchor into the soil to generate an appropriate reaction force, we were able to custom build a concrete anchoring system for our rig in our machine shop. We performed the CPTs at night and conducted pore pressure dissipation testing throughout.
