Hard -v- Soft Projects

The post is explicit: "a detailed design to be finalized for each subassembly, before necessary parts can be procured and assembled."  All construction projects need the design for the part being worked on to be complete before starting work, but you do not need the detailed design for the penthouse finished before you start piling the foundations.

It looks like most construction projects are soft because construction usually starts before the design completion.

Try thinking about the ratio of parallel to serial tasks.
