</>What does Building Manager do?
Building Manager removes the most common delays and failures from Oxygen Not Included construction. Instant Construction reduces build work to a moment, while Free Construction supplies planned buildings without consuming colony resources. Instant Repair shortens repair work, and Repair All Buildings restores every currently damaged building with one action. These controls are useful after an accident, during a major redesign, or while testing a colony layout without waiting through routine recovery work. Indestructible Buildings blocks ordinary building damage, while Prevent Overheat Damage stops machines from being damaged when they exceed their safe operating temperature. Each sustained option can be enabled independently, leaving the rest of the building simulation unchanged.

It can shorten construction and repair work, supply required materials to planned buildings, restore damaged structures, stop ordinary building damage, and prevent overheat damage. The options work independently so colonies can use only the assistance they need.
