January 17, 2006: Unbuilding the Grace cantilever truss
Watching the unbuilding acrobats beats the circus any day of the week. Here
Sparky captured the continuation of building the Town Creek truss structure -
piece by piece. Earlier we saw Ken Canty's step by step sequencing of the
cutting process. Here is another example. An overview of the Port side
of the Grace cantilever

Supported by the crane, our acrobats burn through the plate

Burning in context - on top, buring through the plate while the crane
stabilizes the girder section

A gentle lift and separation (note lower right gap)

continued cutting through the top girder

more cutting, lifting and separation

final separation

and break away

rotating to lower the segment on the barge

The edge of the port-side cantilever, the Drum Island cantilever
and lowering the section

down to the barge

then laying it over on its side

almost down and

down and sleeping
