Its not a hard job to do every thing is ready to lay your cable down under the floor tiles,
Its basicly running lengths/bunches of cat6/cat5e utp cable to every desk/floor-box or wall socket terminating the module side then the patch panels in the comms room.
The communications cabinets can be the hardest of them all due to the overall presentation,
All honesty its no harder than running a patch lead from your modem/router to your pc or laptop.
