How the tender documents of a public building are put together

The tender documents for a public building run to between seventy and a hundred pages, plus annexes, plus spreadsheets, plus forms. And you have to extract one single decision from them: bid or not.

Most teams read from the beginning, run out of steam somewhere in chapter three and decide on what they managed to see. It is the worst possible approach, because what decides the matter is spread across four places and none of them is the beginning.

Since 2026, nearly every tender is the same tender

This changed how you read. Since Ley 2022 de 2020, the national procurement agency adopts documentos tipo — standardised tender documents of compulsory use for every authority under the general procurement statute. They are no longer written authority by authority: they are forms.

And the package that concerns public architecture is the Documentos Tipo de Infraestructura Social, whose current version was adopted by Resolución 539 de 2025 — alongside other resolutions in the same package for the other procedures — and which applies to processes whose notice of call is published from 16 February 2026. It covers five subsectors: education, health, recreation and sport, institutional buildings and housing. Which is to say: schools, health centres, sports venues, administrative headquarters.

The five parts of a standardised tender

The part people underestimate is the experience matrix. It is a spreadsheet, it does not look like part of the tender documents, and yet it is what determines which experience the authority will verify according to the type of works, the specific activity and the value. Open it late and you open it when there is no time left to obtain a certificate.

The order in which it is worth reading

It is not the order of the contents page. It is the order of the decision, from what rules you out fastest to what rules you out slowest:

1. 1The programme. It is an annex, not a chapter, and it fixes the closing date, the site visit and the windows for observations. If you do not have the time, that is where the reading ends.
2. 2Experience. The eligibility requirements chapter, plus the experience matrix. It is where most bidders fall, and you can tell in twenty minutes.
3. 3Financial and organisational capacity. The indicators in the matrix, against your accounts for the year the process requires. It is arithmetic: it works or it does not.
4. 4The scoring factors. Here the question is not whether you can, but how much you will score. And it is the only part of the tender that cannot be corrected afterwards.
5. 5The grounds for rejection. They sit near the start of the base document and almost nobody reads them, because they sound like a formality. They are not.
6. 6The technical annex and the official budget. What the works actually are, with what quantities and at what rates. This is the part that decides whether the contract can be delivered without losing money.
7. 7The risk matrix and the draft contract. What has been transferred to you, what bonds you will be asked for and how you will be paid.

Experience: where most bidders fall

Experience is evidenced by three things at once: what is recorded in the registro único de proponentes — the national register of bidders — the experience form you fill in, and the documents supporting whatever the register does not prove on its own. The assessment is made on the register current and final before the closing date, not on what you have actually built.

And having built is not enough. The tender separates principal activity from secondary activities, and within the principal one, general experience from specific experience. A process for a school may ask, as general experience, for construction or extension or refurbishment of buildings; and as specific experience, that at least one of those contracts covered a floor area equal to or greater than a percentage of the area of this process. The secondary activities are separate: roofing, data networks, whatever the technical annex demands.

The second condition is about value, and it works the opposite way round to how people assume: the more contracts you use to evidence it, the higher the total value you have to reach. Piling up paperwork is not rewarded.

What can be remedied and what cannot

This is the most important line in the whole tender, and the one that produces the most expensive surprises:

The conditions that disqualify you without showing it

Grounds for rejection sound like paperwork until one of them catches you. These are the ones I have seen bring down technically sound bids:

• —The register of bidders is not final on the closing date. Registering is not enough: the entry has to be final, and that takes time.
• —You did not renew the register by the fifth working day of April. If you did not, its effects lapsed and you are out of every process that year until you register again.
• —Your objects clause does not allow you to perform the contract, or that of one of the members of the temporary consortium. It is a paragraph in the certificate of incorporation and it is fixed by amending the articles, months in advance.
• —You did not submit the bid bond — garantía de seriedad — with the bid. This one cannot be remedied, and the statute says so expressly.
• —The bid exceeds the official budget. Even slightly, and even if everything else is impeccable.
• —Crossings-out or alterations not validated in documents evidencing eligibility requirements or evaluation factors.
• —You modified the budget schedule: added, removed or changed items, descriptions, units or quantities. The schedule is filled in, not improved.

Time limits: those of the process and that of the works

There are two kinds of time limit in a tender and they are worth not confusing. Those of the process are set by regulation and are the same across the country:

• —Observations on the draft tender documents: ten working days in open tendering and five working days in abbreviated selection and the concurso de méritos, from publication.
• —In a concurso de méritos the evaluation report is published for three working days and must contain both the eligibility requirements and the award of points.
• —The site visit has a date and time fixed in the programme. A delegate holding a professional licence may attend; it need not be the legal representative.

The other limit, the delivery period, is not set by regulation: the authority chose it. And it is the one that ruins the most contracts. Signs that a period is not realistic:

• —The programme does not acknowledge the rainy season at the site. Across much of the country that means two windows a year, not an inconvenience.
• —The period includes approvals that do not depend on the contractor: licences, discharge permits, easements, utility company sign-off. If that sits inside the period and is not already resolved, the delay will be yours.
• —There is no time allowed for approving designs or surveys between signature and start on site, where the scope includes them.
• —No advance payment is provided for, or it is paid late, and the first quarter’s cash flow depends on you funding it.
• —The period is the same as an earlier process by the same authority that was extended twice. That is public and can be checked.

If the subject matter is design, the tender is a different one

Everything above describes a works tender. When the subject matter is surveys and designs, the procedure changes: it is a concurso de méritos, and with it changes the most important rule of all — price cannot be a selection criterion for engaging consultants. How that procedure works from the inside is set out in the article on public architectural competitions.

What is worth keeping in mind when reading a concurso de méritos tender: the regulation obliges the authority to state how it will score, among other things, the bidder’s experience, the team’s experience and the team’s academic qualifications. Which means the CVs are not an administrative annex: they are part of the score, and therefore they cannot be remedied later.

The decision, in five questions

1. 1Is the register of bidders final, renewed, and with the experience correctly classified? If the answer is not an emphatic yes, nothing else matters.
2. 2Do the contracts you will submit add up to the required percentage, in SMMLV, and do they meet the principal and secondary activities?
3. 3Do the financial indicators work with the accounts the process requires?
4. 4What score will you realistically get, and which scoring forms must be ready on the closing date? Remember: those cannot be remedied.
5. 5Do the period and the official budget allow the works to be delivered without losing money? That one is answered with the technical annex and the budget schedule, not with the summary of the process.

What this article does not say

I declare the gaps, as elsewhere on this blog:

• —I do not give the specific score for each factor. They change with the version of the base document and with what the authority fills in within the permitted ranges. What is stable are the families of factors: financial bid, quality, sustainability, support for national industry, employment of people with disabilities, women-owned enterprises and start-ups, and small businesses.
• —I verified the text of Resolución 539 de 2025, which adopted the current version of the documentos tipo for public works tendering in social infrastructure. The other resolutions in the same package, for the other procedures, I take from the agency’s official announcement and not from their text.
• —The numerical examples on experience come from a real base document, not from the version in force for your process. They are there to explain the mechanism, not to do your sums.
• —I do not set out how the procurement platform operates. It changes with its versions and I did not verify it against current official documentation.
• —I do not go into the regime of special-regime entities, which apply the documentos tipo only where the law requires them to.

The practical conclusion is uncomfortable, which is why it is worth saying: you do not win a tender by reading it well, you win it by being ready before it appears. The register in order, the certificates stating areas and scope, the indicators up to date and the scoring forms prepared. What you decide by reading is only whether the next three weeks are worth spending.
