Corrigendum Meaning in Tender: What Bidders Must Do

Who needs this

• Vendors bidding on GeM, IREPS or other government e-procurement portals
• Small suppliers who prepared a bid from the original document and have not checked for updates
• Anyone who has been told a bid was "non-compliant" after a late change to the tender

What it is

A corrigendum is issued through the same portal as the original tender. It usually carries a reference number that points back to the tender ID, and it states clearly which clause is changed and what the new clause says. Some corrigenda extend the bid submission date. Others only correct a typing error. The purchasing authority is not required to explain the reason in the corrigendum itself.

Eligibility

No eligibility rules apply to a corrigendum itself. What matters is that the bidder is registered on the portal and has access to the tender where the corrigendum is published.

Documents required

Nothing new is needed to read a corrigendum. If the change affects your bid, you may need to update the affected documents, such as a technical specification sheet, a price schedule, or an earnest money or bank guarantee draft, and upload the revised version before the deadline.

Step-by-step

1. Open the tender on the portal and check the corrigendum section, not only the original document.
2. Read the amended clauses against your current bid.
3. List every change that affects price, quantity, specification or eligibility.
4. Revise your bid documents and upload them before the closing time.
5. Keep a copy of the corrigendum and your revised bid in your records.

Timeline

A corrigendum can be issued at any point before the bid close date. Check the portal often, because a late corrigendum can extend the deadline or change the requirements.

Renewal

Not applicable. A corrigendum belongs to one tender.

Penalties

A bid that ignores a corrigendum can be treated as non-compliant. This is the most common reason a bid is rejected on technical grounds even when the price is competitive.

Common mistakes

• Preparing the bid from the original tender PDF and not checking for amendments
• Uploading the old price schedule after a quantity change
• Assuming that a corrigendum announced by email has the same effect as one published on the portal
• Waiting until the last hour to re-upload the revised documents

Advocate's Note

Build a habit of checking the tender page on the day before the deadline, not only on the day you first downloaded the document. Keep a short written note of each corrigendum reference number and what it changed. If a dispute arises, that note is the fastest way to show what you knew and when.
