I set the steel and tied the rebar and dobies. Dobies are small concrete blocks with tie wire embedded within them. These blocks are 3” tall; that is they will suspend the rebar 3” above the sand sub base. This ensures that when the finishers walk on the steel it will not depress into the sub base. You can see some of the drain lines in these pictures.
I also formed the approach as well as the transition from the existing walkway to the new slab.
