Estimate only — not a priced bid document. This tool models the common change-order cost structure (base cost × markup ± adjustment). Actual markup rates, owner/GC fees, retainage and change-order mechanics vary by contract, trade and jurisdiction — confirm against your signed agreement and cost records before issuing a change order.
