01
Count what is actually available
Separate installed material, suitable remaining pieces, pieces reserved for details, and unusable stock. Compare the current work with the original takeoff. Ask whether design changes, field dimensions, cutting, or a changed layout explain the difference. Do not consume planned repair stock without recording the decision and arranging a replacement reserve if it is still required.
02
Confirm the matching order
Provide the supplier with the original product and lot information and state the dimensions and thickness selection again. Ask how the additional shipment will compare visually and whether a sample review is needed. Have the contractor confirm the revised quantity before dispatch. Keep the reconciliation in the project file so the final record explains why the supplied amount differs from the initial estimate.
