The construction site is a large area in downtown Bikini Bottom that is home to some unfinished buildings, with several brick walls, steel girders, a cement truck, and a wrecking ball going towards the buildings' construction. Inside part of a building is a dirt tunnel with active drills that leads to more girders and a glass platform. Below the platform is a cement pool filled with debris, with another similar pool beside it, though the latter pool has a bridge. Beyond the bridge is a path back to the rest of the site and a path to the High Rise apartments.
The construction site is the second part of downtown Bikini Bottom SpongeBob and Mr. Krabs visit to deliver Krusty Krab food, as the site's two foremen have ordered food. Filling the orders gives SpongeBob 20 sand dollars, with an additional sand dollar to earn by exploring the site. After the foremen are fed, Mr. Krabs reveals that people in the nearby High Rise apartments have ordered food, and heads for the apartments.
The construction site later becomes the area where SpongeBob searches for one of the Flying Dutchman's lost treasures. After finding the treasure chest, SpongeBob finds the fourth treasure; a dirty black wig with pigtails.
