Key Considerations

ACP/DDP

Deep pile

Engineered grout

Low spoil - DDP

Concrete cleanup

Flat stable pad

Pile connections

ACC/DDC

Impermeable

Rigid inclusion

Gravel cushion

Grout with low spoil

Concrete cleanup

Flat stable pad

CSC/CAP

Vibration system

Requires confinement in liquefiable layers

Spoil haul-off -  CAP

Semi-rigid inclusion

Casing

Moderate depth limit

VSC/VDC

Vibration system

Requires confinement in liquefiable layers

Soft clay need grout

Big operation for small site

No work next to buildings

RIC/RVC

Vibrations at
30 ft

Pad grading

Import needed

Shallow depth - RIC

High noise - RIC

MP/HP

High material cost

Steel below water

Pile connections

Need access
