In first fix on new builds I have seen professionals do soldered jobs faster than using plastic pushfit. Putting in copper pipe with fittings that push together with a some flux in is quick and easy. Less clips to support it too. Then it is a matter of going around and soldering the fittings. A two man team can do this in no time at all. And the cost is a fraction of the plastic stuff.
