Default Dock building

I want to build two docks, one permanent and a floating one. The floating
one will be supported by 15 gallon plastic drums. I can get 55 gallon,
but for a 4 x 8 dock, I worry about center of gravity issues.

The permanent one will be built of 55 gallon drums filled with dirt. Any
issues to look out for?

The 55 gallon drums filled with dirt may float because of the air trapped
in the dirt. If soaked after positioning and filling, they still won't
weigh much. Concrete blocks are something like 30-40% thier (in air)
weight when submerged.
You can "jet" pilings in with a trash pump. Last time I rented one was a
couple years ago and it cost me $25/day. In a day you can jet around a
bazillion pilings. Four of us non-professional jetted in 40 pilings in a
couple of hours.
I use an old pontoon platform for my dock but I'm interested in the details
of how you "jet" a piling in and exactly what a "trash pump" is. I have
need to put in a permanent short pier at the edge of the bank to support
the land side of my ramps to the dock. I had piers supported by 2 inch
pipes driven into the shore bottom but last years flood lifted the pier and
the pipes right out of the ground and bent everything to hell. I figure 4
inch well pipe would hold up but the only contractor on the river with the
equipment capable of driving them is apparently not interested in any new
business. I tried for 3 years to get him to give me a quote on some rip
rap or vinyl wall (his advertised business) but he doesn't seem interested.
I had $26,000 in my budget but I didn't really want to tell him that up
front.
