Hi sidewinder;
Whenever I've undergone a huge job like that ive utilised
A/001, A/002 to A/130 in 1 block
then
B/001, B/001 to B/130 in another
and then kept some documentation as to which number ports are located in which room.
The new PFI build I moved into last year must have been taged and labelled by monkeys using a randomiser.
ie Room CG1 ports go.....
UG001, UG002, UG003, UG045, UG005 and so on looking for UG004 made us end up in CF4 (next floor up)
Strange!!!
