Hi, I am looking for an estimated cost of making a patio slab. 80 Meters. Any ideas please?

Here's a start.

FWI:  "80 meters" means nothing.  Specify square meters or better cubic meters (how thick you need the slab).  Then you can probably get some estimates.

Sorry for my lack of clarity. I meant to say 80 SQM. Also the thickness can be 10 CM.

80m2 

100cm = 4 ins 

9m2 per cube (approx)

10 cube to be sure.

 

Are you going to get this mixed on site or delivered by lorry and poured ?

Tiles to finish ?

 

A lot of variables, my guesstimate subject to tiles and your location 20 - 25k

 

Very rough calc 10 cub mt concrete 18500 baht. Rebar 1/3 concrete cost 6250 baht total 25000 baht. Same as CharlieH.

I am sorry but your calculations make no sense.

 

100cm is 1m

100mm is approx 4"

 

9m2 is 0.9m3 exactly, not approx

And 80m2 will be 8m3 that rxact, not approx

So why tell him he needs 10 to be sure, may aswell say 20 to be surer

 

I tell you if you order 2m3 to much with readymix you are gonna know about when its to dispose of, plus the 4k bt for over estimating.

 

Footings are ok to add 10% as you will lose it in a trench, a prepared bed should be cock on

Well take me out and stone me ! I made a mistake by putting cm  instead of mm.

Whoops!. but although that was quite obvious by the OP, nice of you to be so critical and precise for the OP.

 

The rest is "approx" as stated, and the rest is all guesswork as there is far too little information to be "precise".After all he wanted an "estimate" not a quote.

(IMHO)

Yes maybe I was a little beligerant, anyway dont do it again or the QS in me will pull you up again.

Thanks guys that helps a lot. Now the next question is how much time should be involved... I wonder about the fair labor cost for a contractor to manage a job like this? Tiles can be installed but I would buy them myself separately.

Ready mix around B1,700/m3

Rolls of rebar mesh say B5,000

Additional 4 bags of portland cement if you're going to polish B600.

Time to lay and polish one day.

Foreman B750/day x 1

Labourer B500/day x 4

Should include the concrete polisher.

All in around B22,000, agree with Charlie's guesstimate.

Grollies, how big exactly is your whip?

 

The op anticipates a tiled finish so obviously your quote (which i agree with) is only for day 1

 

Tiling 80m2 should cost an extra 2500bt for  labour and adhesive,....by this stage you should have already dismissed the foreman

31,25 baht per m2 for floor tiling ?? really ? I personally have never ever got it less than 100 baht a m2 and thats labour only. Guess areas/locations do vary wildy.

Just giving you an opportunity to get your own back

 

 

Its ok, i am getting my coat

Of course Charlie quite rightly pointed out that even the best of us make simple mathematical errors.

 

Labour for tiling will generally run between 180-250bt m2...add on adhesive and call it 300bt

I left out the tiling....whoops.

 

As for the whip. My three guys and one lass could lay 80m2/day and polish starting at 7am the foreman finishing polishing by 8pm.
