In addition to their function in horizontal control, batter boards are also used for vertical control. The top edge of a batter board is placed at a specific elevation. Elevations of features in the structure, such as foundations and floors, can be located by measuring downward or upward from the cords stretched between the batter boards.

You should always make sure that you have complete information as to exactly what lines and elevations are indicated by the batter boards. You should emphasize to your crewmembers that they exercise extreme caution while working around batter boards. If the boards are damaged or moved, additional work will be required to replace them and to relocate reference points.
