Site Setting Out: The Relative Merits Of Different Methods.
Posted 18 January 2016 - 06:29 AM
We've had a few posts asking questions relating to site setting-out so the purpose of this thread is to look at the (relative) merits of the many different methods available.
As this is intended for use by newbies and (building) site virgins, could contributors explain in plain English any technical terms used?
Not sure how this will pan out, but let's see how it progresses.

Fill the demijohn (or other largeish vessel) to approximate level (that is, slightly higher than the height you want to build to)
Insert tubing and, using siphoning, fill the tube with the water
Adjust the level of the water to the desired level (that is, exactly the height you want to build to)
The water in the tube is at the same level as the water in the demijohn ('cause physics)
Go around the profile board posts (Profile, or batter boards are planks that support lines to which bricks or block are built to to ensure they are correctly positioned, usually suspended on posts driven into the ground, and set a few feet away from the location of the building work. One plank is set at each end of a line of block or brick work, with one or more intermediate boards for long runs where the string may sag) with the water level in the tube end, being sure to use the same mark on the tube each time
When the boards are fixed on the marks you will have them all in a single, level plane
Do not drop the end of the tube below the level of the water in the demijohn or the water will drain out affecting your level
Ensure the tubing is long enough to reach the most remote post

It's going to be a bit of a slog, methinks.

Our house is a rectangle with a square sunroom to the rear. The diagonal of the house was coming in spot on at 17.1 m in both directions so onto the sun-room.
We couldn't get the thing square no matter what we tried.
Turns out we had set the rear wall of the house 1m short exactly 500mm on each side.
Took a bit of head scratching to sort that out after a days work.
As for the method we didn't use any tubing or water but my Da is called John. We used the very simple method of 2 posts banged in with a cross member and then pulled a string line level to set out the guides.
EDIT: it wasn't a very successful method as our garage ended up 600mm wider and 300mm longer. The house is 300mm wider and 200mm longer but there you go.
