increase the import and export of cargo and will accommodate
approximately 100,000 additional containers. Coastal
Marine Construction LLC was brought onto this three-phase
project in late 2018, and recently completed the third and
final phase of pile driving in February.
“We started on the first phase with general contractor,
which included the installation of a 1,200 LF long, king pile
bulkhead and the demolition of all of the marine structures
that were in the footprint of where the new pier was going,”
said Eugene Kelley, estimator at Coastal Marine. “Then, when
D.W. White won the additional phases of the project, we went
right from installing the bulkhead wall to driving the piles.”
Based out of Canton, Mass., Coastal Marine specializes in
marine and heavy civil construction and is considered to be
one of the best when it comes to pile driving, earth support,
bridge, pier and deck construction, and demolition. The company
takes great pride in its proven track record of delivering
projects of all sizes on time, safely and within budget. The
company has also established a strong working relationship
with Massport and works on up to 80 per cent of the port’s
marine work.
The deep foundation of the Conley Terminal project
included the installation of almost 900 26- and 30-inch
diameter steel pipe piles that were between 60 and 105 feet
in length. Some of the piles were driven from land, but the
majority were installed from the water by barge.
The piles were driven a few feet into the rock where overburden
was present, with approximately 100 of the 30-inch
diameter piles along the face of the pier having drilled rock
sockets where overburden was minimal. The inshore and
outshore crane beams and pile caps are cast-in-place pieces
and lock together to provide the framework for the deck,
which consists of 870 precast deck panels with a cast-inplace
topping slab. The pier work also includes a new gantry
crane running rail, marine bollards, fenders, drainage, water
and electrical installed on the deck.
When driving the piles, Coastal Marine made use of the
Berminghammer L27 crane-mounted Vertical Travel Lead
(VTL) system. When paired with Coastal Marine’s cranes,
Berminghammer’s VTL system combined the fast and
