The term Construction covers a lot of ground, in fact, one might argue that all our actions and thoughts involve different sorts of construction - although they are not necessarily constructive! - and this is also true in Carl Barks' duck stories. But in order to narrow down the vast theme, the sub-pages will primarily deal with constructions of the more solid kind such as buildings and building projects of various kinds. The more spectacular inventions by Gyro Gearloose will have no place here; instead the chosen examples lean towards the more humorous aspects and they are mostly out of the ordinary.
