The designer measured, went back to his office; entered the drawings
into a CAD program, a few days later he brought the cad drawing back
to my house to re-verify all the measurements. (he measured within
1/16 inch tolerance no wiggle room). I signed off on the job, when
they scheduled my job I asked if I could see them cut it. It was so
simple, the designer downloaded the drawing to the machine from his
CAD program, the operator selected and positioned the starting 0,0
coordinate over the slab and pushed a button, the robot did the rest.
So they have relatively the same labor costs for complex or simple
designs, thats how they can charge the same. The machine pays for
itself in volume as they can process more granite than a manual labor
shop, and not have to pay the health insurance costs for siliconosis
poisoning due to dust.
The installers came with the slabs and they slid right in tight.
