How a tender changes after it is published: pre-bid queries and corrigenda

When a pre-bid conference is held

A tender is not a fixed text between publication and the deadline. It has one scheduled moment for questions and one formal way of changing, and a bidder who knows both reads a different document from one who does not.

Rule 173(x) provides for the meeting in “case of turn- key contract(s) or contract(s) of special nature for procurement of sophisticated and costly equipment or wherever felt necessary”. That last phrase is why a pre-bid conference turns up on ordinary tenders too.

The Goods Manual fixes when it should fall: “The date and time for such a meeting should normally be after 15 to 21 (fifteen to twenty-one) days of the issue of the Tender Document and should be specified therein.”Department of Expenditure, Ministry of FinanceSo the date is on the notice, and it sits early, inside the first three weeks of a tender's life, not near its deadline. Attendance is optional: the Model Tender Document says “Participation in such a Pre-bid Conference is not mandatory”.

Silence is not free

The same clause carries the price of staying away. “If a bidder does not participate or submit any query, then no subsequent representations from them regarding the Technical/ commercial specifications/ conditions shall be entertained.”Department of Expenditure, Ministry of Finance (hosted on CPPP)

That is the sentence to plan around. The pre-bid date is the last day on which a restrictive specification, an unclear qualification clause or an impossible delivery period can be raised at no cost. After it, the same objection is a letter the buyer is entitled to ignore, and after award it is nothing at all.

What a written query should say

A query is a form, not an argument. Three things make one answerable: the clause number it is about, the difficulty it creates for a bidder who could otherwise supply, and the change being asked for. A query that says a condition is unfair, without naming the clause or proposing wording, gives the buyer nothing to issue.

Some queries stand on published policy rather than on a bidder's inconvenience. The Government's press note on the Make in India amendments of 16 September 2020 states that “Specifying foreign certifications/ unreasonable technical specifications/ brands/ models in the bid document is restrictive and discriminatory practice against local suppliers.”Press Information Bureau / Ministry of Commerce and IndustryA specification naming a brand, a model or a foreign certification is therefore a query with a policy behind it, which is not the same as a promise that it will be changed.

Send it in writing, to the address the notice names, before the date the notice sets. A question asked aloud on the day and not put in writing leaves no record that a representation was made.

Minutes are not a change: only a corrigendum is

This is where bidders lose money. The Works Manual is explicit that a change discussed in the meeting has to be issued formally: the techno-commercial requirements “may be revised if considered necessary by way of issue of a formal corrigendum (mere minutes of the meeting of pre-bid conference would not suffice)”.

A corrigendum may be issued “At any time prior to the date of submission of bids”, and the buyer may issue one “whether at his own initiative or in response to a clarification sought by a prospective bidder”. So the two routes to a change are the department's own second thoughts and a bidder's query. Both end in the same document.

Nothing else changes a tender. Not an email from a dealing officer, not an answer given aloud in the meeting, not a line in the circulated minutes. A corrigendum replaces the wording it names; everything short of one leaves the tender exactly as published, and a bid built on the assurance rather than the document is a bid built on air.

Where a corrigendum appears, and whose job it is to find it

Publication is a rule, not a courtesy. Rule 159(i) makes it mandatory for central ministries, departments, attached and subordinate offices and autonomous or statutory bodies to publish their tender enquiries, “corrigenda thereon and details of bid awards” on the GeM-Central Public Procurement Portal. The portal is the Government's own Central Public Procurement Portal, and publishing a corrigendum is one of the standard steps in the tender workflow the system supports.

The Model Tender Document says the same thing at the level of one tender: “The corrigenda and addenda shall be published in the same manner as the original Tender Document”, and “Any corrigendum or addendum thus issued shall be considered a part of the Tender Document”. It then puts the duty where it hurts: “the bidders' responsibility is to check the website(s) for any corrigenda/ addenda”.

Two consequences follow. A corrigendum you never saw is still part of the tender you bid against. And the copy that governs is the portal's, not a forwarded PDF, a newspaper notice or a departmental page that was not refreshed. Where the notice sits in the stages either side of it is on the tender lifecycle; the reading order for the notice itself is on how to read a Notice Inviting Tender.

What a corrigendum usually changes, and the clock after it

Four kinds of change are the ones a bidder meets in practice.

• Dates. The submission deadline, the opening date, or the pre-bid date itself.
• Eligibility and qualification wording. A turnover clause, a similar-work definition, a registration or certification the tender named: the clauses on similar work and turnover.
• Specifications. A relaxed standard, an added make, a corrected drawing.
• Quantities and money. Items or quantities in the Bill of Quantities, or the bid security amount the notice asked for.

A change to the terms is only half of it; the other half is time. After clarifications or modifications following the pre-bid meeting, the Works Manual says “at least two clear weeks should be given for submission of bids”. A substantial change with no extension is itself worth a written query.

Check the effect on your own arithmetic before anything else. A revised quantity changes a price; a relaxed specification changes who else can bid; a moved deadline changes when the security must be in place.

Your bid on the portal after a change

If you have already frozen a bid and a corrigendum lands, the portal expects you to bid again rather than to leave. NIC's own description of the system says “Bidders can resubmit the bid any number of times. Bidder can also withdraw the bid”.

Withdrawal is the one door that does not reopen: “If a bidder withdraws their already submitted bid against a tender in the portal, then the bidder will not be allowed to participate in the same tender once again.”National Informatics Centre (NIC), Central Public Procurement PortalSo a corrigendum is answered by resubmitting, never by withdrawing and starting again.

Make the check a habit rather than a task: look at the tender's corrigendum list on the day you start pricing, on the day you assemble documents, and again on the day you submit. The submission-night sequence itself is on submitting on a NIC portal, and a bid that answered a superseded version of a tender is one of the standard failures on why bids are rejected at technical evaluation.
