PILE JETTING SPOIL CLEANUP

Vacuum machine purchased for the project.  The machine can be positioned over 1,900 feet from the construction site reducing damage to the root mat.

 

Vacuuming cleanup operation can be accomplished during construction rather than after construction saving valuable time on the project.



Only a very small area is disturbed using the vacuum method of cleanup.  The Corp of Engineers and other environmental specialists request the department to use this method on environmental sensitive areas.

Pile Jetting Spoil Cleanup Takes Top Honors

The Manteo Resident Engineer’s Office was faced with a challenge to develop a method of cleanup for spoils generated during the installation of piling in sensitive wetlands for the new Croatan Sound Bridge Project.

A method of conveying the material approximately 1900 feet to high land was identified during a search of methods utilized by other industries. Environmental Agencies approved this method of cleanup as their preferred method.

In addition to a 45-day reduction in the construction time, NCDOT was able to realize a net saving after equipment cost of $3,056,346.20.  This improvement was so successful that the US Army Corps of Engineers required this process on the next wetland project.
