The Excavation Crew Productivity Calculator relates excavated volume to the labor-hours used to produce it. It reports cubic yards per labor-hour and also shows the crew’s average hourly and daily production, giving estimators and field managers a consistent way to compare actual excavation performance across shifts or projects.
The calculation is most useful when the volume and labor period refer to the same scope. Crew productivity can be influenced by soil or rock type, excavation depth, haul arrangement, groundwater, shoring, traffic control, utility conflicts, equipment selection, operator skill, and waiting time. For that reason, the result should be treated as an observed project rate rather than a general industry standard. Use comparable work when carrying the rate into a future estimate.

1. Enter excavated volume Use the quantity completed during the measured period, preferably on the same measurement basis each time.
2. Enter crew size Count the workers whose hours are included in the production period.
3. Enter work hours Use the average hours per worker per day represented by the volume.
4. Enter days Use the number of workdays covered by the reported quantity.
5. Review rates The main figure normalizes production by labor-hours, while the supporting rates show crew-level output.
Total labor-hours = Crew size × Hours per day × Work daysLabor productivity = Excavated volume ÷ Total labor-hoursCrew production per hour = Excavated volume ÷ (Hours per day × Work days)
Where:
Excavated volume = completed excavation in cubic yards
Crew size = number of workers
Hours per day = hours worked per person per day
Work days = days represented by the volume
Assumptions: The model assumes the entered crew size and hours are representative across the measured period. Equipment ownership and fuel are not converted into labor-hours.
What the result means
Use the result as a planning estimate tied to the inputs and assumptions shown above. Compare it with project-specific records, drawings, specifications, and field conditions before making commitments.
Inputs and production factors can vary by material, equipment, crew, measurement basis, and site conditions; update the assumptions when better project data is available.
Given:
Excavated volume = 800 cu yd
Crew size = 5 workers
Hours = 8 hr/day
Days = 2
Calculation: Labor-hours = 5 × 8 × 2 = 80 labor-hours Productivity = 800 ÷ 80 = 10 cu yd per labor-hour Crew rate = 800 ÷ (8 × 2) = 50 cu yd/hr Daily production = 800 ÷ 2 = 400 cu yd/day
Result: 10 cu yd per labor-hour
This crew averaged 50 cubic yards per crew-hour over the measured period. Similar future conditions are important if the rate is reused for estimating.
Should equipment operators be included in crew size?
Include them when their labor-hours are part of the production effort you want to measure. Apply the same rule consistently when comparing jobs.
What volume basis should I use?
Use a consistent basis such as bank cubic yards or another project-defined quantity. Mixing bank and loose volumes can make comparisons misleading.
Do delays count in the hours?
They do if the entered work hours include them. That can be useful for an all-in field rate, while a pure operating rate would exclude non-operating time.
Can I compare two crews with different equipment?
Yes, but the difference may reflect equipment capability as much as labor performance. Record major equipment differences alongside the productivity rate.
Why use labor-hour productivity instead of only cubic yards per hour?
Labor-hour productivity normalizes the result for crew size, which helps compare differently staffed operations. Crew output per hour is still useful for schedule planning.
