As New York City’s Freedom Tower starts to take shape at the site of the
former World Trade Centre, Big R Bridge has been busy collaborating on a
key temporary pedestrian walkway from the existing Liberty Bridge, over
West Broadway, around the large construction site.
Big R team overcomes many challenges
project had problems from the beginning. The original bridge contracting
team was removed from the project, and the new contractor Windham
Enterprises was forced into immediate action. They contacted Big R about
options for an accelerated bridge construction plan using the existing
foundations and other components already placed. Working with Windham,
we were able find a solution, while meeting the desired delivery
Unfortunately, the project became delayed by a series
of design reviews by various community groups and stakeholders. In the
end, a new design from Big R Bridge was agreed upon that finished the
temporary walkway with a more-appealing, translucent paneling to prevent
the busy pedestrian route from becoming a construction site
‘stop-and-gawk’ platform – a community group concern.
A tight timeline requires accelerated construction during each project phase
three of the project was for a 135' approach ramp and an 88' box truss.
Phase two was for the wall and roof structure on the phase three
structures. Oddly enough, project circumstances saw phase three ordered
before phase two. With Big R’s success in meeting the accelerated
demands for phase three, we were then given the green light for phases
two and one, in that order, as long as an early April delivery date
could be met for both of the phase one and two material. Time from order
to delivery for the additional work was now going to be only seven
weeks. Big R engineers and drafters worked around the clock to meet the
quick deadline and had the drawings done for submittal and fabrication
within a week.
Significant design and fabrication changes were
also needed along the way to accommodate unforeseen issues with the
previous contractor’s foundations. All of this was done while meeting
the original time schedule, and pushed the determination and skill of
our engineering, material acquisition, fabrication and traffic
departments. In the end, everyone’s expectations were exceeded.
Bridge installation complete in less than three hours
When the structure arrived, the contractor assembled the bridge and
set it in less than three hours and commented that they had previously
set bridges manufactured by several other bridge manufacturers but none
of them had ever fit together as well as this one had.
