The Unnamed Construction is a large abandoned building without any clue to know the identity of this building. It is located in Bone County, in the east of Arco del Oeste, northwest of Cock Rock, and southwest of Valle Ocultado. It appears to be a factory or something related to industries. Its close proximity to Area 69 leads many players to believe that it is operated by the government. If the player uses a map editor, such as MEd, the building is listed as some sort of laboratory.
The dirt road leading up to the building contains an unusually high amount of traffic on it, but this could be a vehicle spawn glitch.
