A close relative is an architect. The way construction projects are managed is waterfall.

It is made worse by the fact that you typically have 1) a large number of different expert firms involved, creating huge dependencies (imagine instead of FE & BE, having 8 different types of engineers, that can only work in a certain pre-defined order and have very limited availability (so if you are late and miss a slot, they may only be available again a few weeks or months later) 2) communication is either physical meeting of principles (bosses/managers) - rarely actual workers, email or paper print outs. It is not uncommon for on premise workers to work with month old plans that have since been changed.

Buildings are one of the few purchasable objects that have gotten more expensive over the last decades (compared to pretty much every consumer goods item).
