Amendment to Tender

An amendment to a tender is any post-publication change to the Notice Inviting Tender (NIT) or associated bid documents. In Indian procurement, the terms amendment, corrigendum, and addendum are often used interchangeably, though strictly a corrigendum corrects an error while an addendum adds new content. For practical purposes, all such changes reach bidders through a notification on the e-procurement portal and alter what must be submitted.

What is an Amendment to Tender?

An amendment to tender is a document published by the Tender Inviting Authority (TIA) that officially modifies the original NIT. Amendments arise from pre-bid conference feedback, internal reviews, statutory requirement changes, or errors discovered after publication. The amendment is published on the same portal where the NIT first appeared and is linked to the original tender reference number.

Common amendments include: extension of the bid submission deadline (the most frequent), revision to the Earnest Money Deposit (EMD) amount, relaxation of the minimum turnover or experience criteria, change to BOQ quantities or specifications, and clarification of the two-cover system requirements. Each amendment carries a sequential number (Corrigendum No. 1, Corrigendum No. 2, and so on) so that bidders can track the version history.

GFR 2017 requires that all amendments be published on CPPP (eprocure.gov.in) for central government tenders. When an amendment materially changes the NIT, the bid submission deadline must be extended to give all bidders adequate preparation time.

Why Amendment to Tender matters for Indian vendors

An amendment can entirely change the competitive landscape. A turnover relaxation that lowers the minimum average annual turnover from Rs 15 crore to Rs 10 crore can double the number of eligible bidders overnight. Conversely, an amendment tightening specifications may exclude a bidder who had already begun document preparation.

Failing to download the latest amendment before submission is a common reason for disqualification. E-procurement portals (GePNIC, CPP Portal, IREPS) auto-notify registered bidders, but the responsibility to check and comply rests with the bidder.

Example

NTPC issues an NIT for supply of 500 KVA DG sets valued at Rs 12 crore, with a minimum turnover requirement of Rs 18 crore averaged over three financial years. After a pre-bid meeting, two vendors argue the criterion is overly restrictive. NTPC issues Amendment No. 1 reducing the turnover threshold to Rs 12 crore and extending the submission date by 10 days. Three additional vendors who were previously ineligible now participate, and the resulting L1 price is Rs 10.8 crore - 10% below the estimated cost.

Frequently Asked Questions

Q: Do I need to acknowledge receipt of an amendment?

Many e-procurement portals require bidders to digitally confirm that they have read and accepted the amendment before they can upload their bid. Check the portal's submission checklist for this requirement.

Q: What is the difference between an amendment and a corrigendum?

In practice, both terms refer to the same thing in Indian procurement - an official change to the tender. Strictly, a corrigendum corrects an error while an addendum introduces new information, but departments use both terms for any post-publication modification.

Q: Can an amendment change the evaluation method?

Yes, though this is rare and scrutinised by CVC. Changing from L1 to QCBS mid-tender, for example, would attract vigilance review because it alters the competitive rules after the market has already assessed the opportunity.

Q: Is there a limit on how many amendments a department can issue?

There is no statutory limit, but CVC guidelines flag repeated extensions and changes as a potential transparency concern. Tenders with more than three amendments often attract audit scrutiny.
