However.
Ask a Norwegian to fix a piece of road and you will be staring at a hole in the ground for 4 years while people will take turns leaning on a shovel in that hole while surrounded by at least 4 different categories of supervisor or inspector.
But to inject some realism: if they say 4 years they can probably do it in 5. And it'll take another year or so to fix fuck-ups that in retrospect will look stupid and thoughtless, but which are realistically unavoidable. We'll whine about it. A lot. And each week the whole country will be experts on something new. Like evil-sounding compounds for stopping water ingress or how to insulate wires. And then suddenly it starts working.
I can think of a handful of projects that turned out like your example, California HSR and some nuclear plants. The vast majority of projects are completed on time.
You're saying the the general sense from the old germanic language cultures that dwarves and their ilk were somehow Scandanavian is rooted is a well-dug reality?
