One of the more amusing examples of a procurement cock-up is, or so I'm told, the impressive drainage ditches / LandRover traps along the road linking RAF Mount Pleasant to Stanley.....
When they were designed, the contractors asked for the rainfall figure, with which they were duly supplied. They did their sums and advised that these massive structures, rivalling Offa's Dike in size, were clearly needed...
Which indeed they would have been, had the rainfall figure been correct. But 'someone' supplied the annual figure, whereas the contractors had in fact asked for the figure for the wettest
month....
