How would you have solved this?

[biggles34]

Outstanding part of the slab less than the casting pipe (150mm). Need the current height of the casting pipe (1200).

Considered casting a 10x30cm slab outside the edge, but is it suitable and if so how (drill in reinforcement into the slab etc?) How would you solve it?

I would just put a block under the pipe until the concrete has set...

What is the plinth supposed to be for?

Interesting, it certainly makes it simpler.. so no problem to let that piece "hang in the air" afterward then?

Cut the pipe corresponding to the existing concrete and lower it to ground level. Attach reinforcement to the existing concrete.

What should the footing be for?

For joists for decking and pool cover, not enormous weights but they shouldn't move. I was thinking of using two 8mm iron bars in each, is that enough? The outside will be filled with gravel/crushed stone after the wall is fully cured, and concrete will be laid at an angle along the rest for drainage.

Cut the pipe equivalent to the existing concrete and lower it to ground level. Attach reinforcement to the existing concrete.

Unfortunately, I need the entire height of the pipe above the slab.

For beams for decking and pool covers, not enormous weights but they mustn't move. I was thinking of two 8mm iron rods in each, is that enough?

If you're going to have gravel around the bottom part of the form pipe, you can fill before casting and skip the block, it doesn't need to be overworked.
