What is a benchmark in a survey?
A benchmark is a point of reference by which something can be measured. In surveying, a “bench mark” (two words) is a post or other permanent mark established at a known elevation that is used as the basis for measuring the elevation of other topographical points.
What equipment is used for surveying?
The main pieces of surveying equipment in use around the world are the following: theodolite, measuring tape, total station, 3D scanners, GPS/GNSS, level and rod. Most survey instruments screw onto a tripod when in use. Analog or digital tape measures are often used for measurement of smaller distances.
What does a survey benchmark look like?
Survey benchmark monuments are brass or metal disks in the ground that provide latitude, longitude or orthometric height. They give surveyors a point of reference because they use them as part of a set of survey observations. Some benchmarks also provide a reference for elevations.
What are the types of benchmark?
There are four main types of benchmarking: internal, external, performance, and practice.
What is modern survey equipment?
Modern surveying instruments provides faster and more precise surveying than conventional instruments. Their types and uses are discussed in this article. In conventional surveying, chain and tape are used for making linear measurements while compass and ordinary theodolites are used for making angular measurements.

Getting Started with Benchmarking
- Identify where you want to focus.
- Evaluate your current process for that area of focus.
- Identify your blocks.
- Evaluate your implementation process.
- Collect data in a single source.
- Consider hiring a data and process specialist, either on a contract basis or permanently.
