Talking of concrete slabs... another trick that I have used succesfully is
to lay 100mm pvc drainage pipe under the slab, with risers up to the
surface at strategic spots around the building. You can cap the risers
easily enough. These can be used for running everything from cat5 to front
door bells and speaker leads. Draw wires are a good idea, but
electrician's eels will do the job if necessary. The last time I did this
I ended up with about 15 circuits passing through one pipe. Concrete slabs
are very unforgiving if you overlook the need for a particular circuit.

Oblinux: Saves lots of debug time when the problem was actually carpet
"smooth edge" piercing your cat 5 cable and shorting it out. (or the dog
eating it for that matter)
