In my country, a study was done to construct a new runway in the airport. The study specified certain thickness for the runway. The construction contractors built it thinner, to save costs, and the result is that it cracked. Because of this, this is how much money they ended spending: - Initial runway (0.5x cost) - Removing runway to make room for the new one (0.5x cost) - Constructing new runway (1.0x cost) We have a proverb there... "the lazy works twice". This pretty much applies.
