Tender Clarification
A formal question and answer mechanism during a procurement; questions are submitted via the portal and answers shared with all bidders.
Definition
Tender clarification is the formal question and answer mechanism that runs during a procurement. Bidders submit questions through the tender portal (or by email to the named procurement contact) and the contracting authority publishes answers visible to all bidders. The clarification mechanism is essential for two reasons: it lets bidders resolve ambiguities in the specification, and it ensures all bidders work from the same information so no single bidder gains an advantage through bilateral contact with the buyer.
How it works in practice
A typical procurement has a clarification window running until 5-10 working days before the tender deadline; questions submitted later may or may not be answered depending on the buyer's discretion. Questions are typically posted to all bidders along with the buyer's answer; bidder-specific questions can be redacted (the question summarised) but the answer is still shared. Strong clarification questions are: specific (point to a single line or paragraph), substantive (ask about a material issue rather than a typo), and bid-shaping (the answer informs how you will price or structure the response). Weak clarification questions broadcast bid weakness (asking the buyer to explain something that is in the published documents looks like inattention to the documents), help competitors more than yourself (a clarifying question that explains a difficult requirement helps every bidder, not just you), or are too vague to elicit a useful answer. Some buyers reserve the right not to answer questions submitted close to the deadline; check the ITT for the clarification deadline. Where a clarification reveals a material issue with the specification, the buyer may need to issue a correction notice and extend the response deadline. Bidders should track all clarifications carefully and incorporate the answers into their final response; clarifications shape the specification and bidders cannot rely on their pre-clarification interpretation if a clarification contradicted it.
Common questions
When should I submit clarification questions?
As early as possible in the response window so the answer comes back in time to shape your bid. Submitting questions in the final 24-48 hours risks the buyer not answering or answering after your bid is already submitted. Some ITTs set a clarification deadline 5-10 working days before tender submission; check the ITT.
Will my competitors see my clarification questions?
The answers are shared with all bidders. Specific bidder-identifying details in the question can usually be redacted on request, but the substantive question and answer are visible to everyone. Frame questions so they do not broadcast your bid strategy or weakness.
What if my clarification reveals a material specification problem?
The buyer may need to issue a correction notice and extend the response deadline. Material issues (errors in the specification, ambiguities affecting pricing, conflicting requirements) usually trigger this; minor wording fixes usually do not. Raise material issues clearly so the buyer recognises the need to respond formally.
