Interstellar Assembly
Interstellar Assembly is a megastructure in Stellaris 4.5.2 built in 5 stages. Each empire can only build one Megastructure. It needs the Interstellar Assembly technology. All stages take 25 years and 12,500 Unity (the costs every empire pays).

Interstellar Assembly stages
Cost lines with a condition apply only to the empires it names (bio-ship empires pay food instead of part of the alloys).
How it's counted
Totals in the head count only the costs every empire pays: 12,500 Unity.
Interstellar Assembly Site
The construction site station serves as the base for the future construction of an Interstellar Assembly.
