Terraced Educational Garden - Cut and Fill
Writtle College, Essex
In order to calculate the average subsoil cut and fill across the site the average end method of calculation was adopted. This was suitable for this design due to its geometric nature allowing more accurate soil volumes to be calculated.
Before the calculation of subsoil cut and fill a 200mm layer of topsoil was removed from the surface of the designed areas. This would be put to one side during grading and construction and used to dress the site prior to planting.
In order to undertake the caluculations a series of sections were drawn, as shown in the adjacent drawings. The areas of cut and fill were then calculated and averaged to find the volume for each section. This is demonstrated in the table and detailed links below.

The design was split into equally spaced sections to allow the use of the average end calculation method. These section lines were then used to produce a series of sections as shown on the following image.

This shows the sections across the site in relation to the amount of cut and fill that would be required in order to implement the design. The cut is illustrated by the orange filled areas and the fill by blue.
