Construction Sign

The construction signs, or safety signs, are world and settlement objects in the Fallout 4 add-on Vault-Tec Workshop.

Gameplay
A series of warning and instructional signs found in Vault 88. Warnings include those relating to excavation in process, falling material, radiation, and hard hat requirements. In addition, several signs notate sectors of the vault construction site.

Crafting
Note that the sector signs are not craftable. The quest Lady Luck needs to be completed to unlock the signs for crafting outside of Vault 88.
