What indicates the exact grade elevations to the construction force?

In construction surveying, getting the finished surface precisely right requires communicating both exact elevations and how that surface should tilt across the site. Grade stakes provide the exact finished grade elevations at specific points, telling the crew the precise height the surface should reach. Slope stakes complement that by showing the intended incline or slope between points, guiding the grader on how the surface should rise or fall along a line. Together, grade and slope stakes give the construction force the complete information needed to shape the ground accurately: exact elevations where a surface will be, plus the slope that connects those elevations. Hubs and stakes are more about locating and aligning points, not conveying finish elevations. Cut and fill stakes indicate where earthwork should occur and roughly how much, but they don’t pin down the precise finished elevations. Grade with ground rods can establish vertical references but doesn’t by itself communicate the finished grade elevations across the site.
