Feature Request – Automatic Heel Volume Calculation for Linear Measurements

Hi Team,

I would like to suggest an enhancement to the Linear measurement functionality for retaining walls and similar footing systems.

Currently, when measuring a retaining wall footing using the "Linear with Width & Depth" option, the Toe portion can be calculated correctly. However, where the footing includes a heel, users must manually create formulas such as:

([Linear] × [Heel Width] × [Heel Depth])

to calculate excavation quantities, concrete volumes, backfill volumes and other quantities associated with the heel section.

Would it be possible to introduce additional Linear variables such as:

• [Heel Width]
• [Heel Depth]

and have zzTakeoff automatically calculate the associated heel volume in the same way that it currently derives other quantities from Linear measurements?

This would be particularly useful for retaining walls such as RW1 shown on the attached detail, where the heel dimensions vary depending on the wall height. The enhancement would reduce manual formula creation, improve consistency between estimates, minimise user error, and simplify quantity take-offs for excavation, concrete, backfill and related items.

Ideally, users could simply enter the heel dimensions and reference a calculated value such as: [Heel Volume³]

I believe this would be a valuable addition for civil, structural and retaining wall estimating workflows, particularly where heel dimensions change throughout a project.

Thanks for considering this enhancement.
