Salvage & Prefabs

There are a great number of buildings available to support the activities of the colonists. Some are workplaces, while others provide comfort, and yet others are intended to mitigate certain flaws, or just to provide living quarters. Most buildings must be constructed either within or within the support border of a dome. A few buildings may be sent via rocket as prefabs.

Salvage

Salvage is the last option in the Infrastructure menu. The order can be given by selecting any building and clicking the Salvage icon or pressing the Delete button on the keyboard if on PC. Salvaging will destroy the building after 5 seconds, unless canceled, and recover half of the construction costs. The ruin of the salvaged building will remain, blocking any construction where they stand. In order to remove them the Decommission Protocol technology must be researched to enable the "Clear" button to be used. Activating the "Clear" button will signal a nearby drone to completely clear the remnants of the structure.

The salvage order can also be used to instantly cancel the construction of a building.

Prefab buildings

Prefabricated buildings can be launched in Rockets and assembled on Mars for no resource cost. They cost large amounts of funding and cargo space. All buildings except wonders and tunnels can be turned into prefabs for relocation if the Prefab-Refab technology had been researched. Prefab buildings must be transported underground via an Elevator before they can be constructed.
