Colossal means unbelievably huge. A colossal building, a colossal mistake, colossal sums.
It works for size and for scale of error alike — a colossal waste, a colossal failure — and it is one of the strongest words available for both. It comes from the Colossus of Rhodes, a bronze statue about thirty metres high that stood for barely sixty years before an earthquake brought it down. Note colossus; and that the word is used far more often about mistakes than about statues.
