Which stakes indicate the finish elevations on the job?

Finish elevations are the final surface heights the job must achieve after grading and finishing work. Blue top stakes are used to communicate those targets on the ground. They stand out visually and are placed at points where the design specifies the exact finished height, so the contractor can shape the soil to meet those elevations. Other stakes serve different purposes—hubs mark control points and corners, ground stakes are general reference marks, and grade rods are measurement tools used with surveying instruments to read elevations—so they don’t specifically indicate the final elevations. The blue-top stakes uniquely convey the finish elevations to guide the final shaping of the site.
