I can see this thread is old, but just for the fun of it, and to kill some boring time at work:
I use a BIAB system, and use hot water from the fausset. (water quality is really great, never had a problem doing so, although i know People would Object to this...) I only collect the Equipment I need to start mashing: Mashtun, grains and a bag.
-Preparations/Time until i start mashing: 15min.
-mashing: i usually mash for 60min, though i've read some Places People cut this time as well.
During this time i preheat sparge water. (i could also skip sparging, and do a mash full volume)
-sparging 10 min.
-heating to a boil 10 min (i use an induction heater on the side to heat parts of the wort, to increase my efficiency on the boiler)
-boil 60 min
-chilling (plate chiller) 15-20 min, Depends on ground water temp.
-cleaning 20 minutes.
I try to prepare and clean the most that i can while mashing, boiling and chilling.
This should add up to no more than 3,5 hours. The grains have been crushed beforehand offcourse.
I Guess the big time saver in my setup is the BIAB. I saw a great video on youtube from basic brewing making a speedy brew, which also has some great tricks.
Cheers
