Over the last few weeks I have been involved with installing some extraction fans in the local Intermediate School classrooms, to allow air circulation within the said clasrooms.
These are pre-fab rooms, added on bit by bit over the 1970's.
Here is a shot of some of the fans that I installed:

Also here is a shot of the conduit runs for one of the rooms:

Finally, here is a shot of one of the fans.
Shown is the 6" (150mm) dia ducting protruding through the roofing iron and through a Dek-tite rubber sealing Membrane.

And here is all what the kiddies will see from below:

Paul, sorry to stretch the thing out but I'll be blowed if I can find my Photobase software at the moment!. [Linked Image]
BTW folks, there are 12 0f these fans, 3 per classroom, in 4 classrooms.
Just as a note, I ended up installing speed controllers on the whole lot, after I used a 7Core multi cable to supply them, mainly because the fans were too noisy!.
I knew that before the things were even installed, but hey, I do the work, I get paid!. [Linked Image]

You had modular classrooms in the 1970s as well?

We had these "Huts" as they were often called in schools everywhere in the 1970s as schools ran out of room, alt5hough your modular buildings look a little more substantial.

Paul,
Yes these rooms are called Pre-fabs here, because they are built, wired plumbed and so forth before they are fitted into place here.
Just try and install wiring in the darned things, the fellow that originally drilled the holes in the dwangs (noggings), made the holes big enough for his wires, didn't he, but no one else!. [Linked Image]

Gotcha covered Mate!

I was able to make them smaller and faster loading for you. Nice to see that Camera is back in action.

In Canada, they are called "Portables". They aren't actually attached tot he school building, but are standalone. Depending on their location on the school lot, they would get their power form the main school building, or their own service. Communications and fire alarm wire would connect to the main school. They would have no plumbing whatsoever, but would have electric heat and airconditioning.

Bill,
It's 20mm PVC Conduit.

It looks pretty much the same as the 20mm PVC conduit used here.
