Building up an industrial base takes months of in-game time, and that head start often decides the war. The instantconstruction command (alias ic) finishes whatever is in your construction queue immediately, letting you spin up factories and defences in a single day.
How to use instant construction
- Open the console with the
~key. - Type
ic(orinstantconstruction) and pressEnterto switch the cheat on. - Queue your factories, civilian industry, forts and airfields — they complete each day instead of over weeks.
- Run
icagain to turn it off.
Good to know
- It is a toggle, not a one-time effect — leave it on and every new project finishes near-instantly.
- You still need free construction slots and state building slots; the command only removes the time cost.
- Pair it with political power to also switch your economy laws and unlock more building lines.

Frequently asked questions
What is the instant construction command in HOI4?
instantconstruction (alias ic) is a toggle that finishes everything in your construction queue immediately — factories, civilian industry, forts, airfields and infrastructure complete each day instead of over weeks.
How do you turn off instant construction?
instantconstruction is a toggle, so run ic a second time to switch it back off. While it is on, anything you add to the build queue still completes almost instantly.
Does instant construction still cost resources in HOI4?
It removes the time cost, not the rules — you still need free construction slots and the buildings still occupy state building slots. It simply skips the days of waiting for each project to finish.
What is the short form of instantconstruction?
The alias is ic. Typing ic in the console does exactly the same thing as typing the full instantconstruction.
