Building a bridge and Unbuilding a column
The Testa guys can also build - and here is the story of building a work
platform before start to unbuild the concrete pier.
Here is a before photo. The idea is to take down the pier on the left
while protecting the railroad tracks.
The 1250 is first fed by Tony and then takes s short nap before working
The first task is to build a platform over the tracks, then protect the
exposed tracks with a blanket, then launch the 1250 and start hammering
at the left pier cap. Here Michael is taking a bundle of timbers to
place between the two sets of tracks.
He rotates into the bridge building launching position
and gently places them between the tracks while Pio and Richie oversee
the building.
Then the timbers are genly nudged up against the tracks
Then to build the bridge over the tracks, Mike is rotating another group
of tembers into position
more rotation
and positioned to build the first part of the bridge
Positioning the next set of timbers
while Ryan is the fetch and tote man - bringing another set of timbers
within Mike's grasp
and the handoff
After completing the bridge the slope of the on ramp is improved
as you can see here
then Ryan passes to Mike a segment of rubber carpet to protect the tracks
as seen here
and additional segment is added and positioned. To watch the carpet

quicktime (mov) video
then its time to exit the platform
and launch the 1250
Here is the 1250 in its launching position
and onto the bridge (working position). Also note that on the left,
that David and Bryan who manage the water
are already positioned.
Now for unfolding the surgical tools for managing the pier cap unbuilding
and in position. Note that the water has started in order to manage
dust.
Then hammering starts - and will not finish until some time tonight.
Why? Today is a holiday and so there is minimal train traffic.
Tomorrow will be train traffic as usual.
A closer view of the hammer and water spray.
