Inputs

Use realistic productivity and rates for your site conditions.
Tip: If efficiency is 80%, hours rise by 25%.
Total install scope in chosen units.
Examples: m², m, pcs, panels.
Crew-hour means one hour with the full crew.
Skilled workers performing installation.
Material handling, staging, support tasks.
Accounts for congestion, access, learning curve.
Use 2 or 3 for accelerated schedules.
Defines available work time each day.
Gate access, walking distance, tool movement.
Permits, staging, initial setup, unloading.
Tooling, safety checks, cleanup allowance.
Weather, inspections, coordination, hold points.
Covers rework risk and productivity variance.
Supervisor hours per crew-hour (e.g., 15%).
Percent of hours billed at overtime rate.
Common values: 1.25, 1.5, 2.0.
Fringe, insurance, taxes, benefits.
Applied after burdened labor cost.
Used for display and exports.

Hourly Rates

Base wage before burden and overtime.
Use blended rate if multiple helper grades.
Applied using supervision factor above.

Notes: Productivity is per crew-hour. If your productivity is per worker-hour, multiply it by crew size.

Formula Used

The calculator uses crew-hours for production, then converts to person-hours by role.
  • Crew hours (raw) = Quantity ÷ Productivity
  • Crew hours (adjusted) = Crew hours (raw) ÷ Efficiency
  • Duration (days) = Crew hours (adjusted) ÷ (Shifts × Hours/shift)
  • Travel hours = (Travel minutes/60) × Duration(with delays) × Crew size
  • Role hours = Direct hours + allocated shared hours, then × (1 + Contingency)
  • Role cost = Regular hours × Rate + Overtime hours × (Rate × Multiplier)
  • Total cost = (Sum role costs × (1 + Burden)) × (1 + Overhead+Profit)

How to Use This Calculator

  1. Enter your total scope quantity and unit label.
  2. Set productivity as units completed per crew-hour.
  3. Define crew makeup and realistic hourly rates.
  4. Adjust efficiency for site constraints and learning.
  5. Add travel, mobilization, setup, and supervision factors.
  6. Include overtime, burden, and overhead/profit if needed.
  7. Press Calculate, then export CSV or PDF reports.
