For Sparky and myself, curiosity drives passion which in turn fuels our life's engine. Our passion was capturing the story of both unbuilding the Grace (1929 - 2007) and Pearman (1966 - 2007) Bridges and discovering the unbuilders. It takes a lot of passion to track a project from July 2005 until April 2007 - rain, shine, hurricanes or moving to Singapore. We discovered the joy of discovery learning. Ken Canty opened the front door for us - then Steve Testa, Ponch Billingsley and Mickey Rogers opened many side doors. Below are the highlights of what we discovered, who we met and what we learned.
And a reminder from T.S. Eliot (East Coker from the Four Quartets)
Home is where one starts from. As we grow older The world becomes stranger, the pattern more complicated Of dead and living. Not the intense moment Isolated, with no before and after, But a lifetime burning in every moment And not the lifetime of one man only But of old stones that cannot be deciphered.
Early morning - and the trip out to D-24.
and Toby taking us to the worksite - always smiling
Ken is the boss today - Mickey had a fight with his appendix and the docs at East Cooper run
Early morning view of the Ravenel Bridge - golden sun
Before - and Toby - looking over Toby's shoulder. D-23 is over his shoulder. Today's job is to drop D-24 - to the right of the Ravenel support column and near the end of the Grace ramp.
An early morning look east - the D-25 stump and cousin Arthur looking on
and an early morning seagull keeps us company
and Sonny Miller is waiting in his crane to do the vertical fetching and toting.
Here is the horizontal fetching and toting - Ken (in the cage), Phillip, Bret and Toby
Our team: Sonny playing the crane, while Phillip, Ken and Bret play the dynamite - loading the basket for loading D-24
Ken and Phillip, with their protective purple gloves and ready to go
Ken and Phillip loading. The nearer column has been loaded and you can see the faint outline of the fuse lines. Here they are working down from the top of the far column.
Here, Phillip loads a stick of dynamite while in the foreground are the hanging fuse lines from the nearer column.
a closer look - Phillip loads a stemming bag while Ken tamps it into place.
and when all the loading is complete - here is the shock tub3 detonator array. If you have your curious eyes switched on, you might ask why some holes have a cross and other holes have an X. The X holes are incomplete. While drilling, rebar was encountered so that the hole position had to be shifted to one side or the other. The X was painted so that the correct holes would be loaded. Nice piece of documentation.
When all loading is finished, a friendly tug moves our barge.
Looking toward Drum island, you can see the tug pushing our barge as viewed from under the west Ravenel diamond
Meanwhile, on the Grace Bridge, Pio, Richie, Steve and Roy are cutting and removing more roadway.
and if you look closely, you'll see Roy in his cab and Pio in the mega-fork lift to the right.
While on the Pearman approach you can see the outline of the foundation for the Mt. Pleasant observation pier
and a closer look at Bob, Jack, Chris and Michael working on the last Pearman approach piers. In the foreground are the stumps of M1 - M5 and in the background are the support that are in shallow water - requiring a different strategy for preparation.
As the clock kept ticking - the 3pm magic moment approache. 3 toots for a 5 min warning, 2 toots for a 1 min warning , the "fire in the hole" - the blast and 1 toot for all clear. Just like clockwork.
This ignition sequence (stills extracted from the video)
This set of blast photos were an experiment. To see the fuse ignition, the backup needs to be in a shadow. But with a slower shutter speed because of the darker subject, there is a bit of motion blurring. Here you can see the detonation at the base and fuse ignition at the top - like necklaces around each column. So our experiment was a partial success.
Finished - no more D-24 and another clean implosion
A few pieces of residual rebar - to be recycled
For comparison: Before in the early morning
and after: about 3:30 pm
