Rich,
There is cutting. Lots and lots of cutting. The pavers are all square and fit in a modular pattern. We overlay them out past the edge of the design and then mark them with flexible guides. They are all cut with a gas powered 14" concrete demo saw or my 14" gas powered table saw. See me cutting here -[image: 8Map_RS051.jpg]
Pete,
The term hardscaping around here is broad as well, although most homeowners tend to use it to refer to "dry" concrete installations and Masonry is used to describe "wet" installations. For example, the big trade show is Hardscape North America and it features almost exclusively "dry laid" pavers and SRW block.
Also, no, it's not standard practice to install irrigation on new homes. It's all upgrade with a lot of thriving sprinkler companies in the area. They all come in a flush and blow out the lines before winter. Most builders don't even bury the downspouts....even in the homes pushing 7 figures. It's something they typically pay us to do!
