As you can see a water level is the most popular low price solution. A few
years ago I showed guy that was putting new siding on his house how to use a
water level. He thought I was a genius for coming up with such a good
method but I had to confess that it's an old trick probably a hundred years
or more old. In old books I have seen them made by putting glass tubes in
the end of an old rubber hose. The only real advantage of using a laser or
transit is ease of use A pole barn or most residential building don't need
any more accuracy than you can get from a water level

The Egyptians used water levels in laying out and constructing the
pyramids, according to some fairly recent articles in archaeological
journals.

Where? Can't be any leaks. I'd love to see them. Or some key word to
go by to find out what they where thinking.

They didn't need tubing or hose to do it - All the Egyptians had to
do was dig a network of trenches on the site they wanted level and
fill it with water. Use a calibrated measuring stick at each
reference point to transfer the levels to reference stakes, then dry
out the trenches and start leveling.

Once you get the site fairly level, flood the plain a few times
between scraping sessions to observe the low & high spots and correct
them - you could get billiard-table flat with a little time and
effort. (After accounting for the curvature of the earth, of course.)
