Well I know, it might sound funny. However, I'm death serious.

I used to work construction, and it was normally to find a reference point somewhere,where all the contractors had to rely on.

I wonder how that's done in Thailand? For road construction, the use sometimes optical instruments, I would say for a residential building a normal cross laser is efficient enough.

Theodolites I would of course prefer, and I know how to use them. But I guess that's wishful thinking.

Guess the old Pythagorean theorem must do. Failed today because I couldn't find appropriate line in sufficient length to get ahead.

 

 

Spirit Level here where i live and    "That's near enough" ????????

I was in construction too it's just Thai tolerance level have a bigger up or down line. ????

Not sure exactly about the nature of the question.

Just about every pro in Thailand, where necessary, uses cross lasers.

Theodolites are always used by house builders for the site surveying and layout.

If you refer to part-time builders (farmers) then of course, even the basic tools are optional.

It was done by me being here most of the time of build. 

 

While i was away my wife sent me pictures if she was unhappy.

 

Change it and do it better never came up much to be far as they knew my work was in the building industry which my wife continuely  reminded them of. 

I have a story about HK Airport (Chek Lap Kok) and datum points
