Methodology & Sources

This calculator is based on standard construction industry practices for change order pricing (e.g., principles outlined in AIA Document G701 and consensus docs).


Why hidden costs matter: Practitioners often only charge for direct materials and field labor. However, processing a change order requires administrative time (estimating, drawing changes, procurement) and often delays the critical path, accruing daily general conditions overhead or liquidated damages.


Formula: Total Price = (Materials + (Labor Hrs * Rate) + Equipment + (PM Hrs * Rate) + (Delay Days * Daily Cost)) * (1 + (Markup % / 100))
