What is a benchmark on a building?

A benchmark is a pre-determined standard or point of reference against which other things, people, costs, time or activities can be measured. It is regarded as an achievable standard which a failure to achieve could deem the work in question to be unsatisfactory.

What is a benchmark level?

Benchmark is the point laid above or below the datum line with a known elevation. Bench mark is considered as check for the other level points.

What is difference between datum and benchmark?

As nouns the difference between datum and benchmark is that datum is date (point of time at which a transaction or event takes place) while benchmark is a standard by which something is evaluated or measured.

What are the types of benchmark?

There are four main types of benchmarking: internal, external, performance, and practice. 1.

Where does the term benchmark come from in surveying?

The term benchmark, bench mark, or survey benchmark originates from the chiseled horizontal marks that surveyors made in stone structures, into which an angle-iron could be placed to form a “bench” for a leveling rod, thus ensuring that a leveling rod could be accurately repositioned in the same place in the future.

Where can I find a list of benchmarks?

These records are usually in the form of a geographically searchable database (computer or map-based), with links to sketches, diagrams, photos of the marks, and any other technical details. Government agencies that place and maintain records of benchmarks include:

How is the height of a benchmark calculated?

If an elevation is marked on a map, but there is no physical mark on the ground, it is a spot height . The height of a benchmark is calculated relative to the heights of nearby benchmarks in a network extending from a fundamental benchmark.

Which is more important, an arbitrary benchmark or a reduced level?

Arbitrary Benchmarks In most engineering projects, the difference in elevation is much more important compared to a reduced level when it comes to mean sea level. In these cases, the elevation of a permanent structure such as a corner of the plinth of a building might be assumed to have an arbitrary reduced level, like 100.00 m or 500.00 m.
