How to review construction bid addenda before submitting

Before you lock the price, record which addenda you reviewed and where they change the original bid package.

1. Check the official list of issued addenda

Record the solicitation ID and every addendum number from the issuing portal. If your folder is missing a listed file, obtain it before reviewing the package.

2. Verify the deadline and submission instructions

Record the previous deadline and the updated date, time and time zone. Check whether the submission location or the acknowledgement instructions changed.

3. Separate quantity and scope changes

Identify the affected item or specification, its source page and the change to price or schedule. For an illustrative lighting item revised from 48 to 64 fixtures, review the additional 16 fixtures and any related work before pricing.

4. Check the replacement drawings

Record each sheet number mentioned in the addendum. Open the actual drawings to verify revisions. A text check can flag a sheet reference, while drawings and scanned pages still require visual review.

5. Keep the evidence with the bid

Assign each item for review and note the resulting estimate update. In Pawtucket's public RFQ 24-034, Addendum 1 revises the scope in section 4.0 to include additional projects and directs bidders to acknowledge the addendum. Check that instruction in the issuing document for your own solicitation.
