How Do You Answer Bidder Questions During a Bid?

Questions during a bid are a good sign: the sub is reading the documents. They are also the easiest way to make bids incomparable. If one electrician hears on the phone that the lobby fixtures are owner-furnished and the others do not, you get one bid that is low for a reason nobody else knows, and you find out when you level the bids.

Federal sealed bidding writes the rule down. A prospective bidder who wants an explanation of the solicitation, drawings or specifications "must request it in writing soon enough to allow a reply to reach all prospective bidders before the submission of their bids", and oral explanations given before award are not binding (FAR 52.214-6). The government may give general information that would not be prejudicial to other bidders, such as an explanation of a clause, but may not give one bidder information that affords an advantage over others; more specific information is furnished by amending the solicitation (FAR 14.211). And information given to one prospective bidder is furnished promptly to all the others as an amendment if it is necessary to submit bids or if the lack of it would be prejudicial to uninformed bidders (FAR 14.208).

Log each question as it arrives, rewritten neutrally so the asker cannot be identified. The log is how you make sure nothing is answered twice in two ways, and it is the record you go back to when a scope argument starts after award.

Questions 2 and 4 change what a bidder prices, so they went into an addendum. Questions 1, 3 and 5 explain what the documents and the invitation already say, so a posted answer is enough. Question 4 is also a design conflict: the GC does not decide which sheet governs; the engineer does, the same way a request for information would be answered during construction.

One test sorts every answer: would a careful bidder price differently after reading it? If yes, the answer is a change to the bid documents, and it goes out as a numbered addendum that bidders acknowledge. If no, it is a clarification, and a posted answer to all bidders will do.

• Addendum: a quantity, product, responsibility or package boundary changes; a drawing conflict is resolved; the bid date or time moves; a requirement is added or dropped.
• Posted answer: logistics (site walk, where to submit), pointing to where the documents already answer it, explaining a term in the invitation.
• When in doubt, use the addendum. A clarification issued as an addendum costs nothing; a price-changing answer posted as a note costs a dispute.

A question that arrives after the cutoff still gets read. If it reveals a real conflict, answer it by addendum and move the bid date if bidders need time; if it does not, reply that questions have closed and the documents govern. The invitation itself should carry the cutoff; see how to send an invitation to bid.

• Restate the question neutrally, with no company name or anything that identifies the asker.
• Answer from the documents and cite them: sheet, section, paragraph, scope item.
• Answer the question asked; do not guess at intent or add opinions about means and methods.
• Never mention another bidder's price, approach or questions.
• If you do not know yet, say when the answer will come, and make sure it comes before the cutoff for the last addendum.

Subs sit on the other side of the same process; how to bid a GC's job as a subcontractor covers asking well.

In Conflo, bidders ask questions on their invitation to a trade bid. Each question waits on the trade bid's Q&A and addenda tab, which shows how many are still to answer. You answer once, and the answer appears on every bidder's invitation page without the asker's name. A bidder sees every answered question and its own open ones, never another bidder's unanswered question. You can also post a note to all bidders with Ask all bidders, which needs no answer.

Answers and notes do not send an email of their own; bidders see them on the invitation. That fits the rule above: anything that changes the price belongs in a trade addendum, which is emailed to every bidder and must be acknowledged before a bid can be submitted.

Answering bidder questions well is mostly process: one written channel, a cutoff, a log, an answer to everyone without the asker's name, and an addendum whenever the answer changes the price.

Run it that way and the bids that come back price the same documents, which is the whole point of the questions period.
