So I've been told before if the schedule indicate separate 3/4"C you figure it that way. But for these I would think instead of separate pipes from the panel to each 20A load you'd run ONE pipe out of the panel to a location near the loads( they are right next to each other) then branch. Make sense? Although I guess they could hold you to running separate pipes. THoughts?

I would run 1 conduit and price it as 5 # 12 in 3/4 to common location, then branch
 
Running a separate 3/4 for 3-12's is a waste of time and money. Run up to 9 CCC's in each 3/4.
yes agree but you could be held to what’s shown on the drawings . many time you’ll have 20a circuits shown on schedule but no conduit size shown , that makes sense. but sometimes they call for separate conduit . in those cases think you have to figure it that way and not bank on getting approval to combine circuits

Estimate to the drawings and then value engineer it the way you want to run it. Give the owner back a few cents on the dollar to make him happy.

Most of the commercial/industrial jobs I worked on were that way. Plain as day in the prints. Intention I assumed was to leave plenty of room for future expansion.

yes but if someone bidding is pretty sure it won’t be built like that or had past experience with that engineer or architect about that same scenario they could take a gamble and price the way they know it will be built and come in much lower on the price . but it could be a costly gamble.

Yes it is a gamble but often the guy paying the bill has no idea that dumb over engineering is costing him a lot of money. On just about every one of our projects we do some form of value engineering and the client almost always agrees with us to save some money. On large scale projects sometimes the savings to the client can be in the hundreds of thousands of dollars.
