In earthworks, your fleet is only as fast as its slowest link. I’ve been working with a calculation flow that identifies this system productivity by finding the "minimum" output across the whole team—whether it’s the excavator, the dozer, or the trucks. Using Caterpillar and Komatsu standards, this system maps out 26 different activity types from land clearing to quarry blasting. The best part? The dump truck productivity is dynamic, so it automatically updates as haul distances change. No hardcoded numbers—just auditable Excel logic that converts everything into accurate Bank Cubic Meter (BCM) results. Efficiency isn't just about moving dirt; it's about the data behind it.
