## Summary

The risk in a tender rarely sits in the main document. It sits in the annexes and in the addenda that change requirements you already read. Extract every requirement with its exact source, and check the addenda last.

Losing a tender over a missing document is one of the most expensive mistakes a bid team can make, and one of the easiest to avoid. Teams rarely lose because they can't do the work. They lose because a certificate was requested in Annex 4 and nobody read Annex 4.

## Where requirements hide

A typical tender package spreads requirements across four places, and each one fails in its own way:

- **The main document.** Everyone reads it. It is rarely where the problem is.
- **Technical annexes.** Specific accreditation requirements, formats and certifications.
- **Forms and matrices.** Mandatory fields that reveal requirements the text never states.
- **Addenda.** They change everything above, and they can be published days apart.

> **Read the addenda last**
>
> An addendum can change a deadline, a percentage or a required document. If you extract requirements before you go through the addenda, your list goes stale without anyone noticing.

## A repeatable method

  - **Put everything in one place** Main document, annexes, forms and every addendum. If one addendum is missing, the whole extraction is unreliable.
  - **Extract each requirement with its source** Record every requirement with the document and page it came from. Without that, you can't re-check it when something changes.
  - **Separate disqualifying from scored** A missed disqualifying requirement ends your bid. A missed scored criterion only costs points. Mixing them means treating both the same way.
  - **Check the addenda against your list** Go through each addendum and mark which requirements it changes. This pass prevents most rejections.

## Questions worth asking the tender file

These are the ones that surface forgotten requirements most often:

- Which documents must the bidder submit, and in which annex is each one requested?
- Which requirements are disqualifying?
- Which deadlines and dates apply, and which ones did an addendum change?
- What minimum experience is required, and how must it be proven?
- Which guarantees or bonds are required, for what amount and for how long?

> **Ask about what is missing too**

> "Which accreditation requirements appear in the annexes but not in the main document?" is an uncomfortable question for an AI system, and that is why it works. It forces a comparison across documents instead of a summary of the longest one.

You should end up with a list where each line has a requirement, whether it is disqualifying or scored, and the exact page where it is requested. That list is what you review before submitting, and the only way to review it quickly is for every line to point to its source.
