## What does the term RL mean in construction?

Reduced level ( RL ): this is the height or elevation above the point adopted as the site datum for the purpose of establishing levels. To establish the required depths for a drainage system you need to work from the datum point. The datum is taken as a reduced level of 10,000.

## How do you calculate RL levels?

Once you have taken all the levels you want, you will need to calculate the actual height values, or reduced levels ( RL ) by subtracting each one from the instrument height (IH). This gives you the ‘real’ height of the ground at the base of the staff.

## What is the difference between RL and FFL?

Hello and welcome to Just Answer. I don’t see it that often but engineers and surveyors use R.L. for Relative Level or Reduced Level. It is a measurement of height taken from some known datum. F.F.L is First Floor Level.

## What does RL mean in gaming?

Real life. RL is an acronym that stands for “Real life,” which refers to the real world as opposed to the virtual online world. It is often used online in chat rooms and when gaming.

## How do you take rl in a survey?

Procedure:

1. Set up the leveling instrument at Level position 1.
2. Hold the staff on the Datum ( RL +50 m) and take a reading.
3. Move the staff to A and take a reading.
4. Move the staff to B and take a reading.
5. Move the staff to C and take a reading.
6. Move the staff to D and take a reading.

## What is TBM level?

Temporary Bench Mark ( TBM ) – a point of known height above a pre-defined level. This level is not absolute and is defined locally by the surveyor for the purpose of the survey.

## What is RL length?

Total root length ( RL ) was measured as the distance along the long axis of the root from the cemento-enamel junction to the apex. It was divided into three equal parts (cervical, middle, and apical), the root length of each part being 1/3 RL.
