Plant production is a function of geometry, cycle, and condition.
Excavator, dump truck, dozer, roller, volume conversion, and fleet pairing — all from first principles, with the step-by-step working printed alongside every number. No signup. No paywall. No rate library.
§ 01 · How this tool works
First-principles formulas
Bucket × fill factor → payload, swing-factor adjustment, cycle time → cycles/hr. No proprietary tabulations or OEM lookup tables behind the curtain.
Plant referenced by class, not OEM
Excavator, dump truck, dozer, and roller specs are bucketed by weight class and type (e.g. 22t wheeled excavator, 30t articulated dump truck, 13t smooth-drum roller). CivilQuants is not affiliated with, endorsed by, or supplying data from any equipment manufacturer.
Workings trace under every result
Every calculation prints the step-by-step working alongside the headline number. The bill is a function of the geometry — and the function is visible, line by line.
