In early October 2014, EIC attracted national media attention by unearthing
a 19th century shipwreck while driving piles with an RTG piling rig. A
cease and desist order was issued to allow archaeologists and shipwreck
historians to determine the identity of the old wooden vessel. At the time
of this writing, it is believed this could be a Scottish ship known as the
Ayrshire, which was carrying Irish and English immigrants to America.
Two-hundred passengers were on the ship and all but one were rescued.
The investigation and further excavation on this portion of the jobsite
continued alongside of the construction.

for a high-performance machine like ours
because it’s a long stretch of sheet pile wall
and you can really maximize production.”
The use of double sheets, he adds, doubles
production time.
This $23.5-million project required $17
million in steel from Middletown, N.J.-based
Skyline Steel, which mobilized a rotation of 15
truckloads from June 23 through Labour Day.
“With this equipment,” said Serpe of
the RTG pile drivers, “I can drive the sheets
as fast as we can get them on the job.
Overall, it’s been a great experience. It’s
much better than a traditional crane with
a hammer.”
From the clockwork-like handling of the
sheets to the speed with which they enter the
sand, it’s clear that the RTG pile drivers with
high-frequency vibration enabled this level
of production. Raysik adds that a suspended
hammer relies on the weight of the hammer,
whereas high-frequency vibration capitalizes
on both downward force and vibration.
Keeping piles plumb
Himborg seems to know the operation as
well as his machinery as he rattles off specs.
He says the RTG pile drivers feature an
Automatic Self Leveling function to ensure
that sheets are plumb, which is mandatory
on this project.
“During the driving process, the mast is
being monitored,” he said. “When the mast
goes a bit off of being plumb, it automatically
comes back.” A ground man with a hand level
verifies plumbness as the pile vibrates into
the sand.
Steel I-beams pinned in the sand serve
as falsework to ensure the plumbness of

incoming piles. Serpe explains that keeping
the sheets straight is critical to ensuring that
the bent plate cap fits on top properly.
Tight working space
The worksite, framed by a towering dune
and stockpiled steel sheets, is not much
wider than a couple bowling lanes.
The vibration, powdery consistency of
the sand and gravity constantly work to level
the material, further narrowing the channel.
