More concrete sawing, digging down to main sewer line, 2 small trench cut-outs for electrical conduit (floor and island outlets):
They use a rotary saw with diamond cutting edges to get thru the concrete. Each rotary blade costs around $200. Sometimes the blade is ruined when they run thru extremely hard patches or rebar or other metal. Unfortunately, it happened on this job. Fortunately, I'd already agreed on a set price for this small added job.
Plumber worked on putting together his materials list for rough-in plumbing; tile guy came to give an estimate; met with Bill to finalize window rough openings.
