Make sure you receive them
Buyers usually send addenda only to registered document holders. If you got the package from a colleague or a general contractor, you may not be on that list. Register with the buyer or portal yourself.
Check the buyer's notice yourself before you submit, especially on the last two days. Addenda often arrive close to closing, and an email can go to the wrong inbox.
Read it for these five things
- The closing date or time. Has it moved? Put the new one on your calendar.
- Scope. Was work added, removed or changed? Quantities, drawings and specification sections can all change.
- Requirements. A site visit, a certificate, or a bond amount can be added or changed.
- Answers to bidders' questions. These often settle what is included, and they usually count as part of the contract.
- The bid form. If the schedule of prices was replaced, you must use the new one.
Then go through your price
Mark which of your numbers the addendum touches. Tell your suppliers and subcontractors, because their quotes may be based on the old documents. Ask each of them to confirm which addenda their price includes.
Acknowledge it
Most bid forms have a place to list the addenda you received. Fill in every one by number. A blank line can make a bid non-compliant, even when your price already includes the change.
If the last addendum number you have is 3 and a later page mentions addendum 4, ask the buyer before you close.
Keep a record
Save each addendum with the date it arrived, and note what you did about it. If there's a dispute during the job, you'll want to show what your price was based on.
BidCaliper reads each addendum you add, marks what it changed and which of your items it touches, and shows you where to look. It doesn't change your price for you. That stays your decision.
