The grid method has limits. Here is how to close them.
The grid method is the standard for site-formation earthwork, but it under-measures at slopes, corners and edges. A feature-line constrained block method keeps the coverage complete.
Technical guides
Method notes from actual engineering work.
These guides cover specific earthwork calculation methods: when to use them, where they break, and how to close the gap. Drawn from three decades of practice, not textbook restatement.
The cross-section method has gaps. Here is how to close them.
The cross-section method is the standard for corridor earthwork, but it assumes the ground changes linearly between sections. Where it does not, volume is missed. Section densification closes the gap.
