Thats a lot of hours to cut that in. I'm guessing around 5-8 hours I could cut that when I had my 14" MK brick saw. That would include miters on the soldier course. It would probably rip those large rectangle the long way in about 20 to 25 seconds. I would try to demo or rent a bigger saw with enough power to see it it speeds thing up. They are no fun to move at that sizeThis was one we did last year. The kind of thing I am hoping to avoid. Had like 30-35 hours of cutting for a 328 square foot walkway.
