DII/F
If you really want profligate spending look at DII and its precursors.
Stations wired with fibres at £18 per metre only for it to be discarded a few years later.
DII/c wiring discarded in under a year.
DII/f really got the bug - DII/f=2 x QE CVs.
We needed a hole in a wall in the office - 5 inch breeze block. The cost was £120. I was told the cost was the agreed rate for a hole be it in the home counties of the Falklands.
Dii/f sucks and provides little more than email and Office. If you want anything else then it costs buckets to get it acredited.
