Grid and Longitudinal Levelling with Cut and Fill Quantities
Grid levelling measures ground levels on a regular grid, showing where the land is high or low and how much cut or fill is needed to reach the design level. Longitudinal levelling follows a route such as a road or drain.
When do you need it?
- Before levelling agricultural or industrial land
- When calculating cut and fill for contracts or payment
- When designing road and drainage slopes
- When checking levels after grading
What does the work include?
- Tying observations to a known or agreed benchmark
- Observing levels at a spacing suited to the area and accuracy
- Closing the level run and checking differences
- Drawing sections and calculating quantities
What do you receive?
- Table of observations and levels
- Grid map of levels
- Long and cross sections when needed
- Cut and fill quantity table
What to send for a quote
- The site location and boundaries
- The target level or grading drawing
- The use: farm, industrial or road
- The reference used for payment, if any
How the work runs
- We set the grid limits and spacing according to the area and the accuracy needed.
- We tie the observations to a known or agreed benchmark.
- We observe the levels, close the level run and check the difference.
- We calculate the quantities, draw the sections and deliver the tables.
FAQ
What is the difference between grid and longitudinal levelling?
Grid levelling covers an area with a grid of points. Longitudinal levelling follows one axis, such as a road or pipeline, often with cross sections.
Can quantities be estimated before a survey?
Yes. Our free cut and fill tool gives a quick estimate from known levels, but final quantities need field observations.
Is levelling enough to settle contractor payments?
It is a good basis when levels are observed before and after the work on the same grid and reference, and both sides agree the method.
