The Bikini Bottom Construction Company is an extensive group of men who build, demolish, and improve various establishments around Bikini Bottom. They first appear in the episode "Skill Crane."
They appear to have many tools and vehicles for the job, including a crane, in which Squidward crashes into an unfinished mall, and also the Krusty Krab, causing serious damage to it. They appear to be helpful, but vaguely rude. They are seen repairing, and building buildings around Bikini Bottom.
The large muscular, green worker who appears building the Toy Barrel store has been seen having to do community service, and also in the maximum security unit, in Plankton's padlock prison, which is for deadly criminals.
They have a contract with Mr. Krabs, where they are seen building signs for him in a few episodes. Some workers have been to The Salty Spitoon.
