Staging the construction materials: cement trucks, cable anchors, forms etc.
Composing a another movement of the symphony of barges
July 4, 2004
Last week, I sort of stumbled upon the
placing of steel beams on their support piers
and I got to thinking about the logistics and orchestration of the
fabrication, transport, delivery, positioning and final attachment of
all the zillions of pieces bridge stuff. What does the staging
of construction material delivery look like. So this week, I focused on
the construction of the circular piers as well as the bridge platform
and noticed the barges aligned and
ready to deliver the next batch of stuff.
A line of barges with different construction materials - beams with
attached cable anchors, cement trucks, circular forms and rebar. Note
the two spuds to the left of the crane (click on the left image to see
the full image) that anchor the crane to the river bottom.
Much of the steel is fabricated by
High Steel Structures.

Here you can see the extension of the eastward platform, using two
of the anchor beams shown above (July 4). That they have been used is
illustrated in the left photo showing only 2 anchor beams on the barge
in contrast with 4 beams last week (see above).
