If you are building your house with 2'x 6' lumber, your sill plate will consist of 2'x 6' pressure treated lumber.
Lay the lumber end for end along the perimeter of the slab, and measure to fit.
Cut the lumber to size and lay each piece next to its assigned position along the perimeter of the slab.
Now you must mark the location of the holes to drill out on the lumber, to fit over the corresponding anchor bolts.
You must take two measurements for each bolt.
The first measurement is from the edge of the slab to the bolt.
The second measurement is taken from the bolt to the edge of the slab immediately behind it. Add 1/4" to this measurement to allow the sill plate will set 1/4" in from the edge of the slab.
Repeat these measurements for each bolt.
transcribe the measurements onto the corresponding piece of lumber to get the exact location of the bolt onto the board.
