Possible New Pool In Central FL

Still hard to see the actual access for equipment with the pics However it certainly looks like a mini excavator would be more appropriate if you are looking to save your back. It can lay in the lifts much easier than the bobcat. Running a bobcat over the area is not a acceptable means of compaction. Are you having a contractor lay or pour the patio? If so I would ask them how they need the area prepped for the deck. You should be putting at least 6" of a structural material on top of any common fill and the common fill needs to be free from organic material and compacted in proper lifts to avoid any settlement.

It's hard to show the access without a drone but maybe I can get something from our second story today. Basically there is a huge pile of dirt on the left side of the yard that has to be moved to the right side of the yard and used to build up grade for the patio. We're doing paver patio and the paver company has requested a 4" pre-grade for the patio that I believe they will come in and put a paver fines base on to get it to the level needed for the 2 3/8 paver.
 
Side question... Is there any acceptable pressure drop in the plumbing pressure test (not from an inspection perspective but in general)? Is there any good methods to isolate where a pressure loss is coming from?
 
So I'm getting no response from bobcat operators I'm debating renting a 400-700 lb tamper and a T450 bobcat over the weekend to move the dirt around. Am I crazy? I have experience with a bobcat during the military for snow removal not dirt moving. @Rich D here are the best pictures I have I included a drone shot prior to the wall getting put in. My only access to the patio on the side of the house would be to drive over the existing concrete pad

@kimkats I pressurized the pool to Approx 36 PSI on 10/18/2020 today it's at 33 PSI.

Not really following where you need to compact amd get the material. I see a poured wall I'm assuming outside of that is general grading and inside to the pool edge is where you wanna compact. If this is the case, a mini excavator would be better all around but take longer. A walk behind skid would work too a 450 is a tough machine to operate in tight spots without experience. The other thing you could do is see if they have a sheep's foot trench roller they have remote control models. You can do 10 to 12 with them they vibrate.
Moving the pile is easy but I'm not sure if your putting that in as base. What is it sand or dirty sand?

@jimmythegreek ironically for florida it's a lot of clay type material. I need to move the "pile" of dirt to the inside of the wall and compact the newly placed soil for the deck area. Also need to do the grading work on the yard side of the wall.
 
Sorry to keep asking questions but I just want to ensure I'm doing the right thing. The wall got poured late Monday is Friday afternoon too soon to do the backfill? One bobcat person mentioned he was going to drive across our patio concrete to reach the "non accessible side" (which concerns me a little bit). I'd like to get this project going but not at the risk of the wall.

Are you replacing the pavers for the grill pad? Those would be the most likely to be affected. It would be a gamble going across the concrete. Just no telling how thick it is and if there are voids under it. 2 layers of 3/4 plywood would make a big difference with weight distribution and a track skid steer has far less ground pressure than a wheeled skid steer.

Any way to prune up the trees along the back and bring the dirt around that way? Jimmy had a great suggestion with the walk behind skid.

I assume this is a footing for a wall? After 7 days I would have no issues backfilling the footing.

We're doing paver patio and the paver company has requested a 4" pre-grade for the patio that I believe they will come in and put a paver fines base on to get it to the level needed for the 2 3/8 paver.
They are OK using that site material to get to 6" below finish grade?. Not sure if that is standard practice in your area, however I would be bring that material to 14" below finish grade then stabilization fabric then 8" of a good road base material.

You may also have trouble running a plate compactor over the clay. A sheep's foot compactor is recommended for clay.

The grill pad will have new pavers installed on top of it so there is no concern of it getting messed up. I talked to another bobcat guy today and I think he might try to dump over the wall. There is enough clearance for him to fit behind the pool he just can't turn a full 90 degrees to dump so a little shoveling might be required.

This footer was to level out the deck since we had a sloping yard

Yeah out here it's extremely common to backfill with this dirt. Typical is a 4" or so grade with paver fines on top followed by the pavers.

Thank everyone for the replies I'm hoping the Bobcat guy shows up tomorrow afternoon for this but everyone out here is so busy communication is a little difficult[/QUOTE]

Very different building down there for sure. All that material would be graded out amd the leftover hauled off site. I could never put that over the wall. My rule is once its disturbed it gets removed and replaced with some type of DGA. If I used native material for base I would be going back to redo the pavers after 2 winters.
Regardless what you do is spend 200 bucks and use geotextile under any area before you add base material. Clay and vibrators plates dont play well. You end up with jello
 
Well today are Bobcat guy ghosted us we ended up renting a 300 lb reversible plate tamper and starting to move the dirt by hand because we have pavers coming on Wednesday

Unfortunately I canceled my t450 skidsteer reservation when the guy said he was coming and today there were no skidsteers available in the state of florida.

None of the rental places have a Toro dingo or a bobcat mt55 or mt85 ? They are a dime a dozen here and would move that easily

The only place that has anything is Home Depot. I'll probably rent one on Sunday. No Sunbelt within an hour has any skidsteer (track or wheel) or mini excavator
 
Well we ended up renting a ditch witch yesterday and had 2 good friends help along with the wife.

Today we hauled 2 tons of concrete forms to the dump.

It's not perfect but I'd say we made good progress and are ready for a patio.

Threw in a picture of before for comparison

WOW on the friend work! NICE JOB EVERYONE!!! Did you do the machine work in "lifts"?

Yeah we did our best to keep the lifts as small as possible basically with the machine we were able to run the tamper constantly working all the areas
