DEDUCTIONS AND EXISTING STOCK

Grid elevation volume — mean target minus existing height scenarios.

How does changing mean target minus existing height affect grid elevation volume when the other inputs stay fixed?

What this decision changes

A known internal space, existing stock or shared quantity must enter the correct subtraction or eligibility step rather than being counted as new material. Method basis: Enter one mean elevation difference per non-overlapping cell. A negative difference denotes cut. No earthwork design or cut-to-fill suitability is inferred.

The focus is mean target minus existing height in the first repeated measured entry. Other repeated entries keep their own supplied values.

Fill = Σ A × max(Δh,0); cut = Σ A × max(−Δh,0)Grid Elevation Volume Calculator

Evaluate your supplied alternatives

Start with your measured plan and selected product data. The initial values and range are illustrative. Each scenario changes only mean target minus existing height in the first repeated entry; the other entered values stay fixed.

Baseline: Fill volume — 2 m³. Rejected combinations remain visible below.

Quantity to plot

Each bar is one actual calculated fill volume. Horizontal values: mean target minus existing height in m. Only the first repeated entry varies.

Read the evaluated results

Watch the net requirement and actual order separately. Invalid rows identify combinations that cannot satisfy the method's geometric or stock-basis constraints.

Replace every illustrative baseline measurement and selected product value with the inputs for your actual task.
Enter a comparison range on the focused input's stated unit and quantity basis.
Review rejected combinations and use the exact detail lines to distinguish measured demand from whole purchases.

Keep the comparison within scope

The supplied cavity, exclusion or stock eligibility must already be valid; the result does not select a safe shell, opening or construction detail.

Dimensions, layouts, rates and material properties are supplied by the user.

Does not select construction specifications or certify safety.

Only the listed samples are evaluated. Intermediate values, alternate constraints and global cutting optimality are not inferred from the graph.
