bankruatsteve Posted January 23, 2019 Share Posted January 23, 2019 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. Link to comment Share on other sites More sharing options...
ElephantEgo Posted January 24, 2019 Author Share Posted January 24, 2019 Sorry for my lack of clarity. I meant to say 80 SQM. Also the thickness can be 10 CM. Link to comment Share on other sites More sharing options...

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 Link to comment Share on other sites More sharing options...
Toosetinmyways Posted January 24, 2019 Share Posted January 24, 2019 Very rough calc 10 cub mt concrete 18500 baht. Rebar 1/3 concrete cost 6250 baht total 25000 baht. Same as CharlieH. Link to comment Share on other sites More sharing options...

Footings are ok to add 10% as you will lose it in a trench, a prepared bed should be cock on Link to comment Share on other sites More sharing options...

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) 1 Link to comment Share on other sites More sharing options...

ElephantEgo Posted January 24, 2019 Author Share Posted January 24, 2019 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.

grollies Posted January 25, 2019 Share Posted January 25, 2019 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. 1 Link to comment Share on other sites More sharing options...
eyecatcher Posted January 25, 2019 Share Posted January 25, 2019 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 Link to comment Share on other sites More sharing options...

I personally have never ever got it less than 100 baht a m2 and thats labour only. Guess areas/locations do vary wildy. 1 Link to comment Share on other sites More sharing options...

eyecatcher Posted January 25, 2019 Share Posted January 25, 2019 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 1 Link to comment Share on other sites More sharing options...

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.
