Queries and corrections

📐 Article5 min read

What you will learn The duty to report in public contracts, the effect of a correction on the programme, the rule of circulation to all, and practice in private work.

A tender lives through its duration. The queries raised reveal the weaknesses of the package, and how they are handled conditions the validity of the comparison.

The duty to report in public contracts

A precise rule, resting on the bidder.

Errors, ambiguities and omissions in the special specification or in the schedule are to be reported by the bidder to the contracting authority.

That report is made by registered letter or through the dedicated portal, according to the arrangements applying to the procedure.

It must be made at least seven days before the date for returning bids.

This duty is notable: it places part of the responsibility for the quality of the package on the contractor, and it limits later claims founded on an ambiguity that could have been reported.

Situation What applies To whom
Inconsistency spotted Notification before the bid is submitted To the bidder
Correction decided Circulation to every candidate To the client
Query raised A written and recorded answer To the client

The effect of a correction

Two consequences provided for in the rules. They follow the discovery of an error in the documents.

Where errors are found before the tender period expires, or where the description of the works lacks clarity, a correction must be notified to all competitors.

The tender period must then be extended appropriately.

The logic is clear: amending the package without allowing time to take it into account would distort the tender.

The extension is therefore not a favour granted to contractors; it is a condition of the validity of the comparison.

The rule of circulation to all

It applies beyond public procurement.

An answer given to one contractor must be brought to the notice of all.

Answering individually creates an information asymmetry, and makes the bids incomparable with nothing to signal it.

This rule is legal in public work and practical in private work, but its effect is the same: a tender whose participants do not share the same information produces no valid comparison.

It requires queries to be centralised, rather than letting each party answer within its own field.

Practice in private work

Four points, in the absence of a statutory framework. They organise queries and answers on private contracts.

Provide expressly for the arrangements for queries in the tender documents, channel and deadline.

Set a deadline for queries, ahead of the return date, to leave time to answer and correct.

Circulate answers to all those invited, as a numbered note incorporated into the package.

Extend the return date where a substantive correction arrives late.

These four practices are not obligatory in private work, but their absence produces incomparable bids, which defeats the object of tendering.

What queries reveal

An often neglected use.

The volume and nature of queries measure the quality of the package.

Numerous queries on the same point signal defective drafting, to be corrected for future tenders.

The complete absence of queries is not a good sign. It often indicates that contractors priced on their own assumptions rather than asking.

Keeping queries and answers therefore constitutes a body of experience, as well as documenting the tender.

What this means for a professional

Four rules.

Provide the channel and deadline for queries from the tender documents onwards.

Circulate every answer to all those invited, without exception.

Extend the return date on any substantive correction, rather than keeping a date that has become unfair.

Archive the queries, which document the tender and improve future packages.

Frequently asked questions

In public contracts a precise rule falls on the bidder, who must report it before submitting. In private work the practice is set out in the contract.

Two consequences provided for in the rules: circulation to all and a possible extension of the period. A correction not circulated to all vitiates the tender.

Yes, the rule of circulation to every candidate secures equal treatment. An answer given to one alone distorts the comparison.

The ambiguous areas of the package, which makes them a useful indicator. They show what to clarify before the next contract.
