How to Use This Calculator
- Enter the total steel tonnage, number of floors, and average pieces per floor.
- Set the crane capacity in tons at the working radius and the average pick distance in ft.
- Read Picks per Day and Estimated Erection Days to build the project schedule.
- Check Avg Piece Weight (lbs) — if it approaches the crane capacity, a larger crane or rigging plan is needed.
- Use Minimum Crew Size and Crane Utilization (%) to optimize labor deployment.
- Review Tons per Day to benchmark against typical steel erection productivity of 4–12 tons/day.
