Is it a replacement, or going to be a fresh dig? You need to know the condition of the sub-grade. Do you know if you will have to put a capping layer? Might need a compaction test, or a CBR test.

If it's just for horses will fine, if there running tractor or large horse box you need road base under your sub base compact in layers with large ride on vibrating roller

i dont have a clue what the ground is like it feels sturdy but i havent dug any thing yet has im not sure if she agrees to price the stables are to be built by the stable company at york they request that a base for the stables is 150mm reinforced slabin a u shape
other contractors a quoting £45000-52000 just to pour the slab and put atemp rd track for access at 70m long 4 m wide and 138m service trench to run water and electric so the lady is cuting corners to the far end of a fart im afraid she doesnt understand how inportant drainage is im insisting on a soakawaybut she seeing it at more cost and would rather it ran staight into the field.
has for veichles no tracktors just 4x4 and trailer i think horse are the ponie size i havent seen any horses more than 5.5feet tall unless there babys lol
Edited to lower case by giles for those that care

Even big horses are only about a ton for the really big ones, we use special amonia resistant concrete from cemex for them fall each stable bay a point . Trowel with a large big blue then a light brush, arris the edge. Leave one of the engineer or commons out where you've fallen the bays to and collect with a land drain rd the slab, or you'll have a mud bath rd where you get the horses out of the field, Plus you'll have the downspouts from a large roof = lots of water.
That price doesn't sound bad, lot of Crete and finishing to get a good finish, rough tamp finish is nightmare to sweep and trowel makes the horses ice skate with metal shoes on.
And the strong ammonia in animal urine will flake the surface, wants to be a strong mix single layer of overlapped and tied a193 mesh at 150 will be fine.
Depending on size of slab you'll need control joints and expansions joints
You keeping muck on site, and are you leaving the temp rd in or got to take it out and make good, dont buy work....
But good luck

I would price it for the dig 225 of sub-base, the bedding and blocks. if the sub-grade is not up to it, then you would have to re-negotiate for extra dig etc: If they just want you to go to the sub-grade, get them to sign a waver putting in writing your recommendations. Also turn off your caps, large case is classed as shouting.

He'll see what the strata is like when he digs out for his concrete
Most the out comings will stay on site normally with these jobs to fill in hole in the field etc or just thinly layered out.

200-225mm of type 1 laid and compacted in two layers 0f 100-125mm using a double drum roller.
The only time you'd use more than 225mm of sub-base is when there was bad ground and/or exceptional loads, and even then we'd probably look at using geo-textiles, improvement layers or even a bitmac (DBM) base rather than increase the depth of type 1.

thanks guys for help and sorry for( caps on )
im just going stick to the paving and let others worry about concreting
i dont like taking on work im not comfy with but i soppose i will never get any where
if i think like that i can do all the work its just trusting my gut inctinct
really the lady should have contacted a pro stable company like
GB Groundworks who have horses and know the proper materials required
i never thought of horse urine eating away at concrete wow i think i should mention that to the lady
she wont want bad horse conditions

Most use heavy rubber matting in the stables then the bedding layer such as straw/ wood chip it's just going the extra yard. The data sheet is here
