Taking part as a tenderer

One central channel covers almost everything. It is the public procurement register.

The public procurement register is the environment in which authorities run procurements and tenderers take part in them. Anyone can find information there on published procurements, concluded contracts and challenges brought, and the register is public.

The visibility of concluded contracts is an underused source of information. It shows who won which work at what price, which is more useful for assessing competition than any market survey: it shows actual winning prices, not asking prices.

Procurements above the international threshold are additionally published in the Official Journal of the European Union. For construction works that means procurements from €5,404,000 upwards, so most Estonian construction procurements are findable only in the domestic register.

According to information published by the State Shared Service Centre the usual sequence is as follows. The sequence itself is useful information for a tenderer, because it shows when something is expected of them.

Stage	What happens	What is expected of the tenderer
1. Opening of tenders	tenders are opened	nothing, the tender is already submitted
2. Check of economic operators	with an ESPD, a formal check against declarations	the ESPD must be correct
3. Conformity check	whether the tender meets the conditions	the tender must conform
4. Evaluation	tenders compared against the criteria	nothing
5. Selection of the successful tender	the best tender emerges	nothing
6. Check of the successful tenderer	with an ESPD, a substantive check	evidence is submitted now

The last row matters most and is often misunderstood. The substantive check is carried out only after a tender has been found to be the best. That is the point of the ESPD system: every tenderer submits a declaration, but evidence is requested only from the winner. This reduces the administrative burden across the whole market, and explains why a declaration suffices at the earlier stage.

Four things are needed in every procurement, and their reusability is the core of the decision to take part. Most of them can be reused.

What	What it is	Reusable
Company data in the register	tidied data, to be done before the first procurement	yes
ESPD	declaration on exclusion grounds and qualification	yes
Qualification evidence	past works, team experience	yes
Tender content	price and technical solution	no, new each time

The first three are reusable, and that is what makes a second procurement considerably lighter than a first. The first procurement therefore costs more than those that follow, and this must be factored into the decision to take part: judging on the basis of one procurement compares the preparation cost against the return of a single job, although that cost is spread across all the rest.

The practical conclusion is that the decision to take part should be made over, say, a year, not over one procurement. Preparation pays off across several procurements.

Three changes affect tenderers directly. More procurements fall under a simpler procedure, because a simplified procedure may be run up to the international threshold. This reduces formal requirements and lowers the barrier to entry, which favours smaller firms in particular.

The tender deadline for construction works in the simplified procedure extends from 15 days to 25, that is by ten days. This is the most tangible change for a construction firm, because preparing a tender depends on subcontractors' answers, which arrive at their own pace and cannot be accelerated.

The volume of evidence required on subcontractors falls, including the removal of the duty to provide evidence of average wages. That reduces the tenderer's burden.

Change	Effect on the tenderer
More procurements in the simplified procedure	lower barrier to entry
Deadline 15 → 25 days	real time gained in collecting subcontractor prices
Less subcontractor evidence	lighter documentation

One change from January 2026 runs the other way and is rarely covered: the state fees for bringing a challenge were doubled. This raised the barrier to challenging a decision and affects smaller tenderers most, since the fee is a proportionally larger share of the value at stake.

Three things stay exactly the same, and the first is the most common misunderstanding. It concerns compliance of the tender.

Contract terms, which attach to the same work regardless of procedure. A simpler procedure does not mean a simpler contract. If anything the reverse: simpler rules can mean less structured procurement documents, which requires more careful reading, not sloppier.

The binding nature of the tender, which takes effect on submission. The form of the procedure does not change the fact that a submitted tender binds.

Liability for performance of the contract, which does not depend on the type of procurement or the length of the procedure. It follows from the contract itself.

Taking part in public procurement is the same construction work in a different form. Procurements are found in the public procurement register, which also shows concluded contracts, that is actual winning prices. The procedure runs in six stages, and under the ESPD system the substantive check is carried out only on the winner, which lightens the load across the market.

Three of the four things to prepare are reusable, which is why the first procurement costs more than those that follow and why the decision to take part should not rest on a single one. From 1 September 2026 construction procurement allows 25 days instead of 15, more procurements fall under simpler rules, and less subcontractor evidence is required. Contract terms, the binding nature of the tender and liability are unchanged.
