Bid Extension

A Bid Extension is an official notice issued by a contracting authority postponing the deadline by which bids must be submitted, along with the date on which bids will be opened. It is typically issued when the authority needs to clarify specifications, correct errors in bidding documents, or accommodate addenda that materially affect what bidders must prepare.

What is a Bid Extension?

When a buyer issues an addendum or a bid-clarification that changes the scope, technical specifications, or evaluation criteria significantly, procurement rules require that enough time remains for bidders to revise their submissions. If the remaining time is insufficient, the authority must extend the deadline. A Bid Extension is published through the same channels as the original notice, and it automatically extends all bidders' bid-validity periods by the corresponding number of days, so bid securities do not lapse before evaluation is complete.

Bid extensions also occur when the buyer receives fewer responsive bids than expected and chooses to re-advertise with an extended deadline, or when a technical problem with the submission platform prevents timely access. Bidders who have already submitted may withdraw and resubmit, or their original submission is held until the new deadline.

Why Bid Extension matters for bidders

A Bid Extension gives suppliers additional preparation time, but it also creates cost: consultants engaged for bid preparation, staff committed to the submission team, and bank fees for bid security instruments all run longer. Bidders should immediately assess whether the extension was triggered by a substantive addendum that changes their pricing or technical approach, and revise accordingly. Ignoring an addendum and submitting an unchanged bid based on earlier documents is a common cause of non-responsiveness. Suppliers should also confirm that their bid-security bank instrument covers the new submission deadline plus the stated validity period.

FAQ

Does a Bid Extension change the evaluation criteria?

It depends on the reason for the extension. If the authority issued an addendum that alters criteria, the addendum itself changes the evaluation basis. An extension purely to allow more preparation time does not change the criteria.

What happens to a bid already submitted before the extension is announced?

It remains valid but the bidder may modify or withdraw it up to the new deadline. The bid will be held sealed and not opened until the extended opening date.

Can a bidder request a Bid Extension themselves?

Bidders may formally request an extension, but the contracting authority is under no obligation to grant one. Extensions are granted at the authority's discretion in accordance with its procurement rules.
