PROJECT SPOTLIGHT
only were we restricted by the bypass route, we had houses
nearby, including a house that’s only 30 feet away from where
the crane was set up. There was barely enough room to lay
down the box leads.”
Although overhead wires had been moved in preparation
for the project, “They didn’t move them far enough away so
that we could work from both sides of the river,” Tripp said.
“The sheer tightness of the
site was shocking – I’ve
never had such a compact
jobsite before.”
– Pyne Tripp, Tripp Marine
Where the project occurred, Cammies Brook is about
40-feet-wide. He said, “Not a very big span – we could reach
it easily,” with the Kobelco CK 850 lattice-boom crawler crane
selected for the job. “We’d have no room if we had a truck
crane – it couldn’t be done. But this crane rotates on tracks,
so that wherever you work, it’s clear 360-degrees around and
there’s no excess machinery to make the jobsite more cluttered
than it already is. So when I pick up the H-piles to load
them into the hammer from the neighbour’s lawn where we
place them alongside of the road, we turn 180 degrees and
drive them.”
Innovative solution
For the pile driving itself, a temporary crane pad of gravel and
processed rock was first installed on the west side to enable
the equipment to angle-out to drive the 12 piles on the east
side. “The tidal range here in western Newfoundland is about
five feet, and the jobsite floods at high tide,” Tripp said. So an
earthen barrier created out of 1,000-pound plastic sandbags
was positioned around the crane pad, with a pump running
continuously down in the hole while the work proceeded.
“The first day setting up we noticed that the crane pad was
off level, which wouldn’t do for 110 feet of lattice boom with
a diesel hammer, and the available gravel didn’t quite fix it,”
he said, “So we used 20 oak crane mats for the first part of the
project – that was the first day.”
Once the survey team marks where each pile goes with
survey sticks at the centre of each pile, Tripp says, “you drive
them free.” The piles had to be driven on a 1:4 batter, he adds,
not plumb, “but the flying leads don’t mind that at all. You get
the boom down and easily get the batter you need.”
When the piles for the first phase were driven and tested,
the temporary crane pads removed and the land paved,
reconfiguring the equipment took about a week. Tripp said,
“We then drove the west side piles where we’d been sitting to
drive the east side piles. Newfoundland is amazing!”
