Anyone have proven suggestions for building a tower on soft ground?

I’m looking for a time efficient install.  Need a base that will resist rot and not sink into the abyss.

You might start by building a floating dock type base.

im not sure what kind of equipment you have access to, but you could make mats out of railroad ties or green treated lumber screwed together? we have some that are 8" thick for the crane outriggers at work. something like this

Could you use a few existing trees?  Not the ideal setup, but it would get you up outta the water

How tall are you looking to build?  Are there existing trees?  What site are you looking to build on?  Standing water or just soupy mud?

I bought telephone poles and cut them in half.  found them on craigslist for $35 each.

Drilled a hole with my tractor and auger, which immediately filled with water.  The muddy was like soup where I drilled the holes.

Set the posts and built a stand 16 feet in the air.

I had to go back with a load of sand and fill the holes to push the water out and get it to set up. It is now rock solid.

I had some pretty swampy land that I hunted and I bought some bulk rack shelving at a going out of business sale. Two 42" wide up rights and six beams for about $75. I anchorored the uprights to trees so they would not be blown down and then took a plywood for a base with cross beams. I hung up camo and had a very nice blind that sat at 20' high. As far as I know it's still out there on the land I used to hunt.

What kind of access do you have to your building site?

Can you get a pickup in there? Tractor with FEL? SxS?

10 years ago, I built a 7x8 in the swamp, on 8' legs. The door still opens and closes without binding.

The distance to the blind is 200 yards. I had to carry everything in by hand. Tools were either cordless or chansaw.

I used 4x4 legs. I made bases out of 15 inch car wheels with a short piece of 4x4 tube welded to the center to hold the leg.

I built the platform on the ground. With the help of my son, got it in the air and on the wheels. I then leveled it with a shovel. It's still level today.

The first 80 yards to the south of my blind is under water right now, flowing west to east.

Better access means better bases suchs as pads or poles.

I have posted pictures before, they can be found.

For some ideas.

Thanks for all the replies.

I have access with a tractor / truck thru the field.  The soft ground and swamp are about 20 yards in from the field edge.  Everything needs to be trailered by highway to the job site.

I have built towers before but always on dry ground.
My experience has been I end up spending more money on material and time than planned. I would like to try something pre-fab - maybe Redneck or Muddy like.

As to the blind, definitely go with a Shadowhunter, Muddy, or Redneck.  They are expensive but they outlast the plywood boxes by a ton! No mice or insects or wood for porcupines to eat.  Wayyyyyyyy lighter too.  I have a Shadowhunter on stilts that was sinking a bit.  I ran a treated 2x6 from leg to leg on the outside at ground level.  It basically made a lot more contact/baring  area and the sinking stopped.  If you're in really swampy stuff consider putting a pallet under each stilt.

Good advice on Shadowhunter, Muddy, or Redneck.
I agree.  I’ve built my own but materials and time don’t pay off.
