Clear vegetation from the site. We used the OSE pulverizer on the Life Trac 6.

You can strip off the topsoil, as well, or otherwise change the grade at this point. In our case, we had little topsoil and we liked the way the grade worked out by raising the building up on the gravel.

Cut down vegetation in a wide area around your building site, as well. 20' beyond where the gravel will be should be adequate. You will need room for the brick press and rollers, and to stage other materials, too. You will also need room for people to move around and work.
