Right out of college I worked on Terminal 6 in Portland OR. My job was inspecting each and every sheet pile driven into the Columbia R. to create a row of caissons forming the pier face. As you know pile driving is based on driving to resistance. I marked each sheet pile with an approval chalk mark at the resistance point. When done with this project I figured we had driven the equivalent of 20 linear miles of piling. The caissons were then filled with compacted sand and topped with a 24inch concrete deck. Good memories.

That get the attention. Obviously we don't do it for recognition rather a sense of family pride and things like that. We basically do almost every different type of construction while building something below the water , we are licensed and trained to do so , well rounded Dockbuilders are. We do pretty much anything that is below the water level and on the water or shore. One day I'm building a bumper system so boats don't slam into the bridge or the barges , and the next building form work for the freedom towers foundation or even working on the subway tracks and of course there's the divers and tenders who do all the fun underwater work. So its a fun job , lots of different things to chose to do. Thank you again , its nice to talk about what I do every day. Or a summary of it.

It was a joke when they kept sending divers down, but couldn't see anything. I was thinking why not pull dirty water from the bottom of the shaft, filter it and add a bit more clean water so that the clean water in the search area's hydrostatic pressure would push out the dirty water. They act as if people centuries ago would be able to construct something which modern man using modern equipment and techniques wouldn't be able to access. They think there were flood tunnels which are booby traps. No the reason everything floods is because it is a relatively small permable island.
