Earthwork / Buried Pipe
3D normally self-performs excavation and buried pipe operations on the majority of projects we construct. These operations include large footprint excavations (some larger than football fields), as well as deep shaft excavations for concrete in ground structures.
These excavations many times require drilling and blasting of rock and/or groundwater dewatering operations. 3D maintains self-performance capabilities with both of these disciplines. Additionally, 3D self-performs both small and large diameter buried pipe installations (as large as 84” in diameter) in all types of subsurface conditions including in rock underwater or on the side of a 500 feet high rock cliff where the pipe was installed using a helicopter to place the pipe on cast-in-place concrete pipe supports carved into the rock cliff.
We look forward to having the opportunity to work with you. Contact us for additional information.
