Constructor - November/December 2016 - 27


Hamilton Construction Company won
an Alliant Build America award for the
i-84 Sandy River and Jordan Rd. bridges
project in Troutdale, Oregon.

nearby homes, Hamilton Construction Co., in Springfield, Oregon,
came up with an innovative top-down approach. The $58 million
project received an Alliant Build America Award.
"From start to finish, it never got easy; it was a tough job," says
Joe Hampton, project manager with Hamilton. "We had a good team
of people and we all put a lot of effort and time into it."
The company purchased and modified a pair of 250,000-pound
lift capacity gantry cranes, each weighing 100 tons, to launch the
165-ft steel girders from the shore. The gantry cranes spanned
the 90-ft wide bridge superstructure and ran along a fabricated
900-ft long traveling rail that allowed for top-down placement of
the 49 new steel-tub girders, bolted together, with more than 800
bolts at the site by Hamilton crews. This cut the need for piles in
the river from 100 to 12.

"To get it built and rigid enough to withstand the river and
keep the pieces away from the bridge we were going to build
was a feat," Hampton recalls.
The system eliminated the need for a second temporary
work bridge and reduced the flood risk potential associated
with additional piles in the river. It shaved nearly five years off
of the project schedule, with crews able to work year round.
Endangered fish would have allowed a narrow 45-day in-water
work window.
"The gantry was innovative," Hampton says. "Everything is
built up at a high level."
Hamilton has used the girder launcher, but not the gantry
crane, on three other bridge projects, again eliminating the need
for building work bridges and the environmental disruption they
create. The company also has fabricated a bubble curtain into
a circular piece of equipment and drove the piles through the
center of it to reduce the negative effect of pile driving on fish.

SLIDING A BRIDGE INTO PLACE
The Walsh Group in Chicago received an Alliant Build America
Award for its $104-million Milton Madison Bridge Replacement
Project in Madison, Indiana, for the Indiana Department of
Transportation and the Kentucky Transportation Cabinet. The
company built the new bridge adjacent to the old bridge, connecting Madison, Indiana, and Milton, Kentucky, and then slid
the new 30-million pound one into place. The idea, which
reduced the nearly half-mile long bridge's closure from 365
days to a few weeks, gave Walsh an advantage during bidding.

An NTMA contractor has the training, skill,
and experience to understand that their job
is a part of the big picture-bringing your job
to a successful completion.
