Bench Mark

 

a metal disk 8-10 cm in diameter with a 2-mm hole in the center, set into the outside wall of a stone structure (building, tower, bridge) and indicating a point whose elevation above sea level has been ascertained by leveling. The bench mark also bears a number and the name of the institution or government department doing the leveling. In the USSR, the elevation to the hole in the center of bench marks is determined in relation to the level of the Baltic Sea and is cited in the appropriate catalogs.

bench mark

In surveying, a marked reference point on a permanent, fixed object, such as a metal disk set in concrete, whose elevation (above or below an adopted datum) is known and from which the elevation of other points or objects may be determined.

The new levelling provided the determination of the height difference between the tail water level and the headwater level on HPP Medvode and HPP Vrhovo, ensured a unified height basis to perform all design works and future building of HPPs on the Middle Sava River and determined the potential vertical displacements of bench marks that were stabilised in the area (Fig.

AUDIT COMMITTEES CAN USE three recent reports, a General Accounting Office (GAO) survey of bank audit committee chairpersons, a study of audit committee functions disclosed in proxy statements or annual reports and American Law Institute (ALI) recommendations to establish bench marks for their own performance.
Well the way the RVI is run leaves it second to none in my eyes, and if our politicians had any sense, they would put as much resource into the NHS as they can, using competent managers, and maybe use hospitals like the Royal Victoria Infirmary as bench marks of the standard they have to reach.
