Assuming you are referring the the elevation found on typical construction site plans. Elevations are given in feet above sea level (for most of the U.S.). In most cases, there will be a finished floor eleveation (FFE) shown on the prints. This might be 1765 feet above sea level. All other elevations would typically show only the last two digits (which means the whole site is within the 1700 to 1799 foot elevation). But generally all elevations are given relative to an important structure FFE.
