How to Use This Calculator
- Enter the total number of precast panels and the average and heaviest panel weights in lbs.
- Set the cycle time per crane pick in minutes (including set, plumb, and weld) and work hours per day.
- Enter the weather/delay factor (%) and the crane hourly rate and ironworker burdened labor rate.
- Read Picks per Day and Total Erection Days to set your schedule.
- Check Min Crane Capacity (lbs) — this is the heaviest piece times 1.25 and sets the minimum crane size.
- Review Erection Cost, Labor Cost, and Total Project Cost for budget planning and subcontractor negotiation.
