Biomechanical Landscape (work 312)
One can look also at Giger's Biomechanical Landscape (work 312) painting to see another possibly clue to the conception of the painting.
Giger would describe it as bones and electronic devices transformed into warheads at the centre of the painting arranged in a row from top to bottom, so that would be an assembly plant, or they're biomechanoid cousins of Brian Froud's goblin like biomechanoids in an assembly plant, but one can take a look at the the egg like forms in Hieroglyphics running from top to bottom.
