What is a Tender Corrigendum and How It Affects Your Bid

A tender corrigendum is an official correction or amendment issued by the buyer after a tender notice has been published. It can change dates, quantities, specifications, eligibility, documents, or even the evaluation criteria. Ignoring a corrigendum can lead to disqualification, so tracking them is just as important as tracking the original tender.

What Does a Corrigendum Cover?

Corrigenda are issued to fix errors or update information in the original tender document. Common changes include:

• Extension of bid submission or opening dates
• Changes in tender fee, EMD amount, or payment mode
• Revisions to technical specifications, BOQ, or scope of work
• Changes in eligibility criteria or required documents
• Clarifications on evaluation methodology
• Addition or withdrawal of tender lots or items

Why Are Corrigenda Important?

A corrigendum becomes part of the tender document once issued. Bidders must read the original notice together with all corrigenda before preparing and submitting their bid. Failing to comply with an updated requirement can make an otherwise strong bid non-responsive.

Where Are Corrigenda Published?

Corrigenda are published on the same portal where the original tender was advertised. This includes CPPP/eProcure, GeM, state e-procurement portals like Mahaeprocure, and individual department websites. They usually appear under the same tender ID with a corrigendum number and date.

How to Track Corrigenda Effectively

1. Bookmark the tender page on the official portal after you shortlist a tender
2. Check the portal daily, especially close to the submission deadline
3. Subscribe to email or SMS alerts from the procuring department if available
4. Use TenderHub to see updated tender details and corrigendum flags in one place
5. Download and archive each corrigendum with the original tender documents

How to Respond to a Corrigendum

Read the corrigendum carefully and update your bid preparation checklist accordingly. If the deadline is extended, use the extra time to strengthen your technical and financial bids. If specifications change, verify that your product or service still matches the requirement before investing in EMD or bid documents.

Common Mistakes Bidders Make

• Preparing bids based only on the original notice
• Missing deadline extensions and submitting late
• Ignoring changes in document requirements
• Not updating the EMD amount after a corrigendum revision
