How much does a construction worker cost per hour in Thailand?

Hello Bernhard

You should never talk about an hourly wage here !!!!
The costs for a construction worker in Isaan are between 300 and 800 Baht PER DAY, so 8 hours a day
For less than € 22,00 per day.
That difference lies in what kind of construction workers you employ. It is understandable that a foreman who cooperates earns 800 and an accomplice bricklayer between 300 and 500 Baht.
So never talk about an hourly wage because then you make the whole prices to the ……… !!!!!!
The electricians are the most expensive, they are around 1000,00 Baht per day
Greetings Cor.

normally a worker costs 400 baht per day but if you have a contractor come you can also agree on a total price that you would pay in 3 parts upon partial delivery

Here they work on a daily wage not per hour, where I stay you can agree on a fixed price per square meter. The best that you talk to people of the village.

Indeed, the daily wages for “professionals” range from 400 to 1000 THB/day, depending on their specialty.
Clearly agree on what you expect as the end result, on which days they will come to work, as well as the expected end date. This is how you also determine the final amount. It could otherwise run out or become more expensive. It is best to let your Thai family or friends make these arrangements, because the prices charged for a farang are usually (considerably) higher.
Good luck with your project!

Building an isaan house, my story is described a bit above.
If you know what the house should look like
It is better to agree on a fixed price in three installments of work.
Then you know in advance what the labor costs are.

You can also agree on an hourly wage, for a professional it is 400 to 500 baht per day
But then you might be annoyed, when they are waiting for building material, etc.
And buy material yourself, and then make sure that it is on time at the construction site.
My experience is that you regularly have to wait for something to be delivered.
Good luck building

they don't do that Western nonsense in TH-and your girlfriend should know that anyway. per day is usually the minimum/the agreement, but do not count on the fact that the same production as here is performed in 1 day.
As most know, the MIN wage is about 333 bt/day, depending in part. of the region. But IF you can find someone for that mere amount of money, let alone qualified, also strongly depends on the region. the better known craftsmen have huge waiting lists, don't come/come as they please (or other better paying work), so ask others who have built recently and they ask+get more of course. Especially electrical workers are very scarce and therefore more expensive - according to the Thai they are academically trained!
But even at 400/500 bt/day you are still below the hourly wage that is customary in BNL. The average Westerner often finds that paying more for better professionals is certainly worth the return - the cost price per hour is then lower than for less well-paid people who are barely qualified.
IF you also want them to come back regularly etc. then it is important to spoil them as "boss" during the works.

Dear Bernard, the first answer to you is :
€ 1,35 for an 8-hour working day. Then you have a reasonable construction worker.
Our house was completed 3 years ago in Ubon Rachathani.
If you are interested I can give you my email address.

In 2008 we had a house built and requested the total price from several contractors. We took 1 of which we had the best impression ourselves and agreed on the price and the type of building materials.
You do indeed have to be there for at least 8 hours a day because if you turn your back it will already go wrong.
We are glad we did it this way and maybe we have lost a bit more than arranging everything yourself, but if we saw how it goes when some things are not there, you have to be careful that you don't get heart problems. have to wait days for some materials, they have no problem with that, they arrive at work on time and then sleep all day, if you think that they are doing something different in the meantime, then you are not thinking at all in Thai style, no regrets that we let it be accepted and still worked as agreed and finished on time
