I always use the method of equal diagonal measurements to check for square after layout.  Measure opposite diagonals, if they are equal, you're guaranteed square; if not, move things a bit until they are.  The key is to figure out what to move and how far.

I cheat on the layout though.  I use a Topcon total station to get my corners within 0.01' to begin with, and then work from that for more precision.   ;D

FDH, I still use the tried and true batter boards and builders twine to lay out my buildings.  I guess if I would take the time to learn how to use one I could rent a transit and get it down a few minutes quicker, but deep down I am just a simple ole fart ( that's similar to a G.P.I.T.A. only different :D )

Stupid question of the day time........

One, how do you know if the builders twine that you use for your layout is forming square corners if you don't calulate the corner to corner distances to check them?

If you're going to break a law..... make sure it's Murphy's Law.

Murf,
You don't which is why I use the calcualtions I mentioned earlier in this post to check for square.

What to move and how much is relatively simple.

One line or wall of the building or whatever your checking should never be moved ( reference line), measure your diagonal, if the measurement is equal you are square, if not, move the opposite line 1/2 the the differance. Lets say you measure one one diagonal is 100" the other is 101", move the opposite line parallel  1/2". you are square. One two step done.

You will have the post holes dug, posts in place, and dead square by the time the person next door has just set up his batter boards, however, I agree with one of the previous posts, they do have their place, one would be slinging mortar and bricks.

The last large job I was on was a co-generation plant in Longview, Wa.  We poured what we called a rat slab for every set of forms to be set.  This was a rough 4" slab below the bottom grade.  Engineers set all the corners in the concrete and forms were set accordingly.  Took  awhile to get used to not trying to set forms in mud or worse and getting your feet wet from the puddles on the rat slab.  Solid footing for bracing etc was also a nice experience.  Made 100 yard pours easy and common and the large pours[600 to 700 yards] go like clockwork no matter what the weather.

Beetle,
Got my answer and more! I will be laying out my mill shed this weekend ( if it ever stops raining) and the info gathered will be a great help.
Thanks to all,
Moosehunter
