Construction addendum review for specialty subs

Specialty subs who need to know exactly what changed in an addendum before re-pricing their scope.

A sub re-pricing scope after an addendum doesn't have time to compare the new drawings against the old ones page by page — and a missed revision means re-quoting the wrong scope, which shows up as a margin problem after award, not before.

“I got sloppy and didn't go all the way through the 116 page Addendum and of course it was buried near the end. Our scope rarely changes from original prints issued but this one time it did majorly!!!”

“I feel like we are bleeding cash on 'favors' that never get billed.”
