| Scenario | Shift (h) | Downtime (%) | Efficiency (%) | Equip | Output/cycle | Cycle (min) | Crew | Worker prod | Daily output (net) |
|---|---|---|---|---|---|---|---|---|---|
| Truck haul – short distance | 10 | 12 | 90 | 3 | 8 yd³ | 14 | 12 | 0.55 yd³/h | ~144 yd³/day |
| Concrete placement – bucket | 8 | 8 | 85 | 2 | 1.2 m³ | 11 | 10 | 0.35 m³/h | ~47 m³/day |
| Rebar fixing – crew driven | 9 | 15 | 80 | 0 | N/A | N/A | 14 | 2.2 m²/h | ~188 m²/day |
Daily production rate links planning to execution by converting resources and time into measurable output. When supervisors track a realistic daily rate, they can balance deliveries, inspections, and workface readiness. This reduces idle time, avoids over-ordering materials, and highlights where constraints limit progress. It supports daily huddles by setting targets that teams can verify before mobilizing each.
Shift hours define available time, while planned downtime captures setup, refueling, access delays, and brief stoppages. Efficiency reflects actual site conditions such as congestion, supervision, temperature, and crew experience. Rework accounts for waste and quality corrections that quietly consume production capacity. For new teams or changing methods, apply a conservative efficiency until the learning curve stabilizes.
Some tasks are equipment-cycled, like hauling, batching, or lifting, where cycle time and output per cycle dominate. Other tasks are crew-driven, like rebar tying and finishing, where per-worker hourly productivity is decisive. Using the minimum of both capacities prevents optimistic rates that ignore bottlenecks.
Example: shift 8 hours, downtime 10%, efficiency 85%, rework 3%, safety factor 1.00. Effective time equals 7.2 hours (432 minutes). With 10 workers at 0.35 units/hour, crew capacity ≈ 20.8 units/day after adjustments. With 2 machines, 1.5 units/cycle, 12 minutes/cycle, cycles/day = 36, and equipment capacity ≈ 51.3 units/day. Auto selection reports ≈ 20.8 units/day because the crew is limiting, so adding equipment alone will not increase output.
If output is equipment-limited, reduce cycle time through better haul routes, staging, and dispatch discipline, or add capacity with additional units. If crew-limited, increase workface availability, simplify handoffs, and protect uninterrupted working time. Recalculate after changes to confirm gains and keep targets achievable.
1) What is a daily production rate?
It is the net quantity of work completed in one working day, expressed in a chosen unit such as m³/day, m²/day, tons/day, or pieces/day.
2) Why does the calculator use downtime and efficiency?
Downtime removes nonproductive time from the shift, while efficiency adjusts for real site conditions. Together they prevent overstating output compared to ideal textbook performance.
3) When should I use crew-based versus equipment-based inputs?
Use crew-based rates for labor-dominant activities and equipment-based rates for repetitive cycles like hauling or lifting. Auto mode selects the realistic limiting factor.
4) How do I estimate cycle time accurately?
Include loading, travel, queue, unloading, return, and minor delays. Take multiple observations during normal operations and use an average that reflects peak congestion.
5) What does the safety factor do?
A safety factor reduces committed output to manage uncertainty. For example, 1.10 lowers the planned rate so schedules remain resilient to normal variability.
6) How can I improve daily output without adding headcount?
Reduce interruptions, improve material flow, shorten travel paths, and prepare the next workface early. Small cycle and downtime reductions often produce meaningful gains.
7) Should I include rework and waste every day?
Yes, if rework is common or quality checks cause repeat work. Tracking a modest percentage keeps forecasts honest and helps quantify the cost of quality issues.
