Public tenders: preparing the documentation

What repeats in every bid and what has to be redone each time.

Updated on 13/08/2026

Bidding for public contracts consumes days of work, and a large part of that work is redoing what was already done for the last one. The difference between a team bidding ten times a year and one bidding thirty is rarely size: it is how much they have prepared in advance.

What repeats almost every time

BlockHow often it changesWhat to have
Company details and capacityRarelyUp to date and ready
Financial standingAnnuallyWith the last update date visible
Similar works completedWhen you finish oneWith its completion certificate, collected at the end
Certifications and insuranceAnnuallyWith warnings before they expire
Assigned technical teamPer bidWith qualifications and experience already digitised

Important

The third row is the most valuable and the worst preserved. The completion certificate is requested when the works finish, while the client relationship is live; requesting it three years later for a specific tender is slow and sometimes impossible.

How to shorten preparation

  1. 1

    A permanent "company documentation" file

    What repeats, always current, not a folder per tender full of copies.

  2. 2

    Due dates with warnings

    An expired insurance discovered the evening before submission is the classic cause of exclusion.

  3. 3

    One file per tender that links rather than copies

    What is specific to that bid; the common part is referenced.

  4. 4

    And collect the certificate as each job ends

    The highest-yield investment and the most forgotten.

Watch out

Beware exclusion on a formality. Many bids fall not on price or technical merit, but because a document had expired, was wrongly signed, or a declaration was missing. It is the most avoidable part and gets the least attention.

After submitting

That last point reduces future exclusions: the same three mistakes nearly always repeat, and they only become visible once someone has been noting them.

Worth knowing

It applies equally to large private tenders, supplier approvals and supply competitions: the specification changes, not the fact that 70% of what is asked for is always the same.

Can a previous bid be reused?

The common part yes; the technical content and price, no.

What about joint ventures?

Each company contributes to the shared file; agree beforehand who keeps the whole.

How long must submissions be kept?

Years: appeals and reviews can come much later.

A real case

The situation
