Note that this achievement is story-related and I'm only writing a guide for people to know when this unlocks in case they are managing win steaks, percentages, etc.
The last instruction build in the game is in level 11, "Put the Thing on the Thing". When you first start the level you will be in a room with a lot of construction robots lined up. You will be tasked with collecting your instructions and then building a loudspeaker. Once you have completed building the loudspeaker, the achievement will unlock.
