Structural Steel Crew Productivity Calculator
Measure how quickly a steel erection crew is placing structural steel. Enter installed tonnage, crew size, shift length, and days worked to see output per crew-hour, output per worker-hour, and the daily installation rate.
Calculator
Project inputsFormula
Crew productivity = installed tons ÷ (shift hours × shifts worked)
Worker productivity divides installed tons by total labor-hours: crew size × shift hours × shifts.
What the result means
The main result is the tonnage placed by the entire crew in one clock hour. It is best compared across periods with similar steel complexity, access, crane support, and connection scope.
This is a production estimate, not a contractual labor standard. Keep the labor scope consistent when comparing periods.
Example calculation
A crew installs 120 tons with 8 workers over ten 8-hour shifts. Crew productivity is 120 ÷ 80 = 1.5 tons per crew-hour. That is 12 tons per shift and 0.1875 ton per worker-hour.
Tips for better results
- Separate erection hours from fabrication or delivery labor when scopes differ.
- Track simple framing and connection-heavy work separately.
- Use accepted installed tonnage so rework does not inflate production.
- Record weather, access, and crane interruptions beside each period.
Frequently asked questions
Should foremen be included in structural steel crew size?
Include the foreman when the foreman’s paid hours are part of the labor total used for comparison.
Can I enter metric tonnes instead of US tons?
Yes, but every tonnage input and result must use the same tonne unit.
Does the rate include crane operator hours?
Only if you include the crane operator in crew size; state that choice when comparing jobs.
How do partial shifts affect productivity?
Enter partial shifts as decimals so their hours are included in the denominator.
Why can two steel crews have different rates?
Member weight, connection count, height, access, weather, and crane logistics can materially change output.
