Estimating & Workflow
Supplement
A follow-up request to the carrier for items the original estimate missed — code requirements, additional damage, or corrected quantities.
On a real claim
A supplement is a follow-up request to the carrier for items the original estimate missed: code requirements, additional damage, or corrected quantities. On a claim it is how a contractor recovers what the first scope left out, and it is stronger when it cites evidence. What goes wrong: a contractor files one giant supplement late, or sends several small ones, and either loses leverage or slows the file. Check that each supplement item is documented and tied to a reason.
