Construction Simulator/Upgrade levels

Upgrade levels apply to your company as a whole, and unlock as you progress through the game. There are three upgrade levels: S, M, and L. Though it implies "Small", "Medium", and "Large", there are usually no size requirements for these upgrades. Beginning at upgrade level S, complete 3 goals to unlock level M, and then complete three more goals at level M to unlock the final level.

Although many upgrades make mention of construction worker staff and foremen, they are not visible in the open world. Foremen usually appear at the end of a job to speak to and conclude the task, but serve no other purpose and disappear when interacted with.

Most construction goals share a requirement with one of the upgrades in its list.
