Two tenders for the same quantity of plow edges receive a similar number of questions. The first answers them through a single numbered document published to every bidder, and the closing date holds. The second answers them conversationally over three weeks, two bidders receive information the others do not, and the closing date is extended twice. The product being bought is identical; the difference is the process around the questions.
This is the implementation path for that process: setting a question deadline, answering consistently, recognising when a change requires an addendum, and keeping a record that stands up if the award is challenged.
Setting a question deadline
The deadline should be early enough that answers are published before bids are prepared, not merely before they are submitted. A bidder who receives an answer two days before closing has already built the offer, and the answer either forces a rebuild or is ignored.
The practical rule is to set the deadline at least a week before closing, and longer where the specification is technically complex or where the questions are likely to require a supplier to check with a factory. Publishing a planned answer date alongside the deadline, rather than only a cut-off, tells bidders when to expect the response.
Answering consistently to all bidders
Every question and answer should be published to every registered bidder, without identifying who asked. That is the practice which keeps offers comparable, and it is also what makes the process auditable.
Two refinements are worth adopting. Number the questions and answers so they can be referenced in the offers. And answer the question asked rather than the question implied: a reply that adds a requirement is a change to the tender rather than a clarification, and it belongs on the addendum route.
When to issue an addendum
An addendum is required whenever the answer changes the specification, the quantities, the delivery terms, the evaluation criteria or the timetable. Anything that would make a bid prepared under the original documents incorrect falls into that list.
An addendum should state what has changed, restate the affected clause in full so there is no need to reconstruct it, and state the effect on the closing date. Restating the clause is the step that is most often skipped and the one that prevents a bidder assembling the current position from three separate documents.
Extending the closing date
The closing date is extended where an addendum is material rather than where it is tidy. The test is whether a bidder needs more time to price the change: a revised delivery point or a changed quantity usually does, whereas a correction of a typographical error usually does not.
Where an extension is given, the period should be proportionate to the change and stated in the addendum. Extensions granted informally by email produce a position where some bidders know the new date and others do not, which is the situation most likely to result in a challenge.
Documenting the rationale
The record of the clarification process has four elements: the questions as received, the answers as issued, the date each response was published, and any addendum with the reason for it. Together they show that every bidder had the same information at the same stage.
Where a question is declined, the record should carry the reason. A declined question with no explanation is the point at which a bidder is most likely to conclude that the process was not even-handed.
Publishing answers to every bidder
Publication should use the same channel the tender was issued through, and the answers should be visible to anyone who has registered for the tender rather than only to those who asked. Recording the publication date for each response is what makes the sequence provable later.
Where a question is commercially sensitive to the bidder asking it, the answer can be generalised rather than withheld. A generalised answer that addresses the substance keeps the process even-handed while avoiding the disclosure of one bidder’s approach.
Common technical questions and model answers
A tender for plow edges attracts a predictable set of questions, and having a drafted answer ready shortens the response time.
- What measurement method will be used to check the pattern, and against which drawing revision?
- Where is the delivery point, and are the quoted terms delivered or collected?
- What documentation has to travel with each lot, and in what form?
- Is an alternative material or profile acceptable, and what evidence would support it?
- How will a part quantity be split across call-offs, and does the price hold across them?
These five cover most of the correspondence, and drafting them before the tender opens means the answer date is met rather than negotiated. The terms they refer to are set out on the RFQ page.
Running the process without delay
Keep clarifications inside the timetable.
- Publish the question deadline and the answer date in the tender documents.
- Log every question on receipt, with the date and the bidder reference kept private.
- Answer in a single numbered document, published to all registered bidders.
- Route anything that changes a requirement through an addendum rather than a clarification.
- Review the closing date after each addendum, and state the decision whether or not it changes.
The fifth step is the one that demonstrates the process was managed rather than accidental, and it is the element a review will look for.
Where clarifications go wrong
Three failures account for most of the delay and most of the challenge risk.
- Answers given privately, which make the offers incomparable without anyone intending it.
- A change issued as a clarification, which leaves the specification with two versions in circulation.
- A late question accepted after the deadline, which disadvantages bidders who complied with it.
The third is the hardest to refuse and the one most likely to be complained about. The useful response is to answer it publicly if the substance can be generalised, and to decline it otherwise with the reason recorded.
Keeping the award on schedule
Clarifications consume less time than they appear to when they run through one channel. The time savings come from removing the correspondence cycle: one document, published once, to everyone, with a stated answer date.
Where the process is run that way, the evaluation begins with a set of offers that were prepared against the same facts, and the panel can begin scoring rather than establishing what each bidder believed. Public sector procurement practice is published by the National Association of Counties and the American Association of State Highway and Transportation Officials, and trade terms by the International Chamber of Commerce.
SENTHAI manufactures plow edges, wear plates and carbide inserts in Rayong, Thailand, and answers technical questions on patterns, tolerances and documentation in writing, so a bidder can price against a stated position. Questions that need a documented answer can be raised through the contact page, and the clause set the questions usually concern is described on the municipal bid specification page.
FAQ
What is tender clarification?
It is the process by which bidders ask questions about a tender and the buyer answers them, with the answers shared so every bidder works from the same facts. Its purpose is to remove ambiguity from the specification rather than to change it, which is why an answer that alters a requirement becomes an addendum.
Should answers be shared with every bidder?
Yes, always, and without identifying who asked. An answer given privately to one bidder changes what that bidder is pricing, so the offers stop being comparable and the evaluation measures information rather than price.
When should a question deadline be set?
Early enough that answers can be published before bids close, which in practice means a week or more ahead of the closing date. A deadline that falls the day before closing produces either an unanswered question or an extension.
Does answering questions delay the award?
Only where the process is unstructured. A published deadline, a single response document and an addendum route for changes keep clarifications inside the timetable; the delays come from questions answered individually and late, which then force a closing-date extension.
What should happen if an answer changes the specification?
It should be issued as an addendum to all bidders, with the closing date reviewed and extended if the change is material. Sending it as a clarification is the error that produces a challenge, because bidders who priced the original scope are then compared against those who priced the revised one.
