Addenda arrive mid-bid and change everything: revised drawings, new specs, alternates added or deleted. Our addenda and bid revision support services update your takeoffs and pricing against every issued addendum, so the number you submit reflects the final documents, not the first set.
Send the addendum and your original estimate. We cloud the changes, revise the affected quantities, re-price the delta, and return a clean revision summary you can defend in bid leveling.
Addendum-driven takeoff revisions: only the changed scopes re-measured, deltas reported added versus deleted, so you see exactly what moved and by how much.
Revised estimates with a clean delta summary, so when the owner asks what the addendum cost, you answer from a document instead of a guess.
Bid revision support for GCs and subs bidding plan-and-spec work: multi-prime addenda, phased bid packages, and negotiated follow-ups after bid day.
