Prequalification under Law 14,133: How to Use It in Public Works and Engineering Services

Understand how prequalification works under Law 14,133, when it can be used in public works and engineering services, its deadlines, risks and effects on future procurements.

Check it out!

The prequalification procedure provided for in art. 80 of Law 14,133/2021 is a technical-administrative procedure carried out before procurement to preselect bidders that meet qualification conditions or goods that satisfy the Administration’s technical and quality requirements. In public works and engineering services, its most relevant application is to bring forward the assessment of companies that may participate in future procurements or objectively defined works and services programs.

Prequalification does not replace procurement and does not mean advance contracting. It separates a complex stage — verification of technical, legal, economic-financial or quality conditions — from the future competition. The Law allows it to be partial or total, organized by groups or segments, permanently open to new interested parties, and valid for up to one year, also limited by the validity of the documents submitted.

An important consequence is that the subsequent procurement may be restricted to prequalified bidders or goods. This possibility increases efficiency but also raises the planning duty: excessive requirements, insufficient publicity or poorly designed prequalification can unduly restrict competition and contaminate every procurement that follows.

What is prequalification under Law 14,133?

The Law defines prequalification as a selective procedure prior to procurement, called through a notice and intended for total or partial analysis of the qualification conditions of interested parties or of the object.

Art. 80 divides the instrument into two main uses:

• select bidders that meet qualification conditions for a future procurement or for an objectively defined works and services program;
• select goods that meet technical or quality requirements established by the Administration.

For engineering, the first use is especially useful. An Administration with a program to modernize substations, renovate schools, deploy security systems or execute repetitive public works can assess supplier capability in advance and reduce repetitive documentation in each procurement.

This does not mean creating an informal closed registry. Prequalification is a formal procedure, with a notice, objective criteria, publicity and permanently open registration while the Administration maintains an interest in the procedure.

Why prequalification can be useful in engineering

Qualification of engineering companies can involve a large volume of documents: professional registrations, experience certificates, CATs, proof related to the most relevant portions of the scope, operational capability, financial statements, guarantees and other elements.

When the Administration conducts several similar procurements over time, repeating this entire analysis in every process increases administrative cost and supplier participation cost.

Prequalification allows part of this verification to be moved to a permanent and reusable procedure. This can generate three main gains.

Less rework

Documents and conditions already verified do not need to be rebuilt in full for each new competition, subject to updates and document validity.

More time to analyze what actually changes

Instead of concentrating the session on hundreds of qualification documents, the Administration can devote more effort to the proposal, price, design, schedule and specific risks of the procurement.

Building a qualified market

In works or services programs, prequalification makes it possible to know in advance which companies demonstrate capability for specific technical segments.

The Preliminary Technical Study should justify why this anticipation improves the process and which requirements actually need to be verified before procurement.

Prequalification may be partial or total

Art. 80, §7 allows the procedure to be partial or total.

In total prequalification, the Administration verifies all qualification requirements it intends to anticipate for the future procurement.

In partial prequalification, it verifies only some of them. This is useful when certain requirements are stable and others depend on the specific scope.

For example, in a building-renovation program, the Administration may prequalify companies regarding professional registration, general experience, economic-financial capability and management systems. In each future procurement, it may verify requirements specific to the building, the most relevant portion of the scope or the required team.

This separation avoids two extremes: repeating everything in every procurement or creating such rigid prequalification that it cannot accommodate differences between projects.

It may also be organized by groups and segments

§6 allows prequalification to be organized according to supplier specialties.

In engineering, this is particularly important. It makes no sense to use the same list for lightning protection, automation, structural, electrical installations, electronic security and HVAC companies when the technical requirements are different.

A program may have, for example:

• group A — civil works;
• group B — electrical installations;
• group C — telecommunications;
• group D — electronic security;
• group E — automation;
• group F — commissioning and testing.

Each segment may have requirements proportionate to the future procurements.

The procedure must remain permanently open

One of the most important rules in art. 80 is §2: prequalification must remain permanently open for registration by interested parties.

This reduces the risk of the Administration forming a static list and blocking new entrants throughout its validity period.

In practice, the process should specify how new companies can request prequalification, how they will be analyzed and the deadline for issuing a decision.

The Law requires documents to be examined within 10 business days, allowing correction or resubmission where appropriate, with the objective of expanding competition.

This characteristic changes the governance of the instrument. Prequalification is not a one-time event; it is a base that must be managed.

How long is prequalification valid?

Art. 80, §8 establishes two simultaneous limits:

1. a maximum validity of one year, with the possibility of updating at any time;
2. validity no longer than that of the documents submitted by the interested parties.

Therefore, a prequalification certificate cannot be treated as permanent authorization to compete for any future public works contract.

The Administration must control expirations, corporate changes, registrations, sanctions, certificates and other relevant conditions.

It should also assess whether the requirements used remain appropriate to the market and procurement program. In sectors with rapid technological evolution, prequalification can become outdated even before the maximum legal period expires.

The future procurement may be restricted to prequalified participants

§10 of art. 80 allows the subsequent procurement to be restricted to prequalified bidders or goods.

This is one of the strongest effects of the instrument and, precisely for that reason, requires caution.

If only prequalified companies will be allowed to participate, the prequalification notice must have been sufficiently publicized, remain effectively open and use requirements directly related to future procurements.

The TCU draws attention to the risk of restricting a procurement to prequalified participants when the requirements assessed earlier do not correspond to what will actually be needed in the specific procurement.

The decision to restrict participation must be justified. Prequalification cannot become an artificial barrier designed to reduce the competitive universe.

The Technical Review of Procurement Notice and Annexes should verify whether the anticipated requirements remain proportionate to the scope and whether future restriction is technically justified.

What can be assessed in engineering companies?

The Law allows total or partial analysis of qualification requirements. The actual composition depends on the future procurement, but some areas recur frequently.

Professional qualification

• registrations with the competent professional councils;
• professional attributions;
• regular status of companies and responsible professionals.

Technical-operational capability

• compatible experience certificates;
• most relevant portions of the scope;
• technically justifiable quantities;
• organizational experience.

Technical-professional capability

• key professionals;
• experience in related services;
• proof of relationship under the permitted conditions.

Economic-financial capability

Where relevant, checks that are useful for several procurements in the program may be anticipated, subject to the need for updates.

Systems and processes

For complex scopes, there may be justification for verifying certifications, management systems, quality processes or specific capabilities, provided there is a clear connection to contractual risk and no disproportionate requirements are created.

The central point is that prequalification should verify minimum capability. It should not be turned into a competition to select the “best company” in advance.

Prequalification is not technical scoring

This point is fundamental in technique-and-price procurements.

Prequalification answers:

> which companies meet the conditions to participate in the future procurement?

Technical scoring answers:

> among the qualified companies, which proposal presents the best technical attributes established in the notice?

Mixing these two functions can create double counting.

If a given experience certificate was used only to demonstrate minimum capability, the Administration should carefully assess whether and how additional experience may later be scored. Scoring must measure technical value above the minimum, not merely repeat qualification under another name.

The content on best technique vs. technique and price examines this distinction between the entry gate and ranking in greater depth.

Practical example: modernization program for 20 buildings

Imagine an Administration with twenty buildings that will undergo electrical modernization over three years.

The procurements will have similar scopes but different values and specific characteristics.

Without prequalification, each procurement repeats:

• company registration;
• experience certificates;
• CATs;
• economic-financial documents;
• analysis of minimum capability.

With prequalification, the Administration can structure a permanent procedure to verify companies capable of participating in the program. Each procurement can then concentrate analysis on building-specific requirements, the proposal, price and schedule.

If the future procurement will be restricted to prequalified companies, this decision must be provided for and justified from the design of the procedure.

Practical example: electronic security and systems integrators

In an integrated procurement involving video surveillance, access control, VMS, servers and network infrastructure, the Administration may wish to establish in advance a universe of integrators capable of meeting minimum experience and capability requirements.

Prequalification can reduce the risk of receiving proposals from companies without proven capability for integrated systems.

However, it would be inappropriate to require, already at the prequalification stage, every technical particular of a future project that has not yet been defined. The procedure should be built for the real procurement program, not for an excessively broad hypothetical scope.

When prequalification tends to make the most sense

The instrument is especially useful when there are:

• several similar future procurements;
• a specialized market;
• complex qualification documentation;
• objectively defined works or services programs;
• a need to maintain a dynamic list of capable companies;
• goods whose technical quality needs to be verified in advance.

It tends to add less value when there is only one isolated, simple, short-term procurement with no real gain from separating qualification from the competition.

Main risks of poorly designed prequalification

Insufficient publicity

If few suppliers know about the procedure, future restriction to prequalified participants may reduce competition.

Excessive requirements

Requiring experience, quantities or certifications without a proportionate relationship to future scopes creates unnecessary barriers.

A single procedure for very different scopes

Trying to create a universal list of “engineering companies” produces requirements that are too generic for some scopes and too restrictive for others.

Expired documents

Prequalification loses value if the Administration does not control the validity of the conditions analyzed.

Turning qualification into ranking

The procedure should verify conditions for participation, not decide in advance who is technically superior for a procurement that has not yet taken place.

How to structure the prequalification notice

Art. 80 requires the notice to provide, at minimum, the information necessary to define the object, procurement procedure and format of the future procurement, and award criteria.

In engineering, a robust notice should also clarify:

1. related works or services program;
2. groups and segments;
3. requirements for each segment;
4. accepted documents;
5. update procedure;
6. treatment of expired documents;
7. analysis deadline;
8. appeal mechanism;
9. publication of the list;
10. whether future procurements may be restricted;
11. how specific requirements will be handled later.

The Terms of Reference for Public Works and Engineering Services for future procurements should remain consistent with what was prequalified.

Prequalification and long-term planning

The greatest value of the instrument appears when the Administration has a portfolio view.

An agency that knows its works pipeline can organize segments, anticipate market analysis and keep capable suppliers available throughout the program.

This brings prequalification closer to a procurement strategy: the Administration stops looking at each procurement in isolation and begins organizing market capability for a sequence of contracts.

But this approach requires governance. The market changes, suppliers enter and leave, documents expire and technical needs evolve.

Checklist for deciding whether prequalification is worthwhile

Before creating the procedure, ask:

• will there be more than one compatible procurement?
• are the qualification requirements sufficiently stable?
• is there a specialized market that justifies early analysis?
• can the Administration keep the procedure permanently open?
• can the segments be defined objectively?
• does the effort saved exceed the cost of administering the list?
• will there be a team to update documents and publish results?
• is future restriction to prequalified participants really necessary?
• do the requirements avoid targeting and excess?

How to separate what should be prequalified from what should be judged in the procurement

Prequalification works best when it removes repetitive and stable checks from the future procurement without anticipating proposal evaluation. In engineering, this separation is decisive because minimum capability, experience, team, methodology and price belong to different moments in the selection process.

The procedure under art. 80 may preselect bidders that meet qualification conditions for a future procurement or an objectively defined works or services program. This allows the Administration to validate in advance requirements that tend to remain relatively stable across several procurements.

Element	Prequalification	Future procurement
Professional registration	may be verified in advance	confirm validity when necessary
Minimum technical-operational capability	appropriate for prequalification	should not be turned back into competition without reason
Minimum technical-professional capability	may be part of the filter	additional professionals may be assessed according to the scope
Economic-financial condition	may be included where relevant	time-limited documents must be updated
Project-specific methodology	generally not the focus of the generic filter	evaluated when it forms part of technical scoring
Technical proposal	should not be replaced by prequalification	evaluated according to notice criteria
Price	does not define prequalified status	forms part of the future procurement award process

The logic is to avoid double counting. If a given experience certificate was already used to prove the minimum required for prequalification, the future procurement should not simply reward whoever submits more documents of the same type, unless there is justification for assessing quality or additional experience above the minimum. Otherwise, the procedure stops simplifying and merely moves bureaucracy from one stage to another.

In a technique-and-price procurement, for example, prequalification may confirm that all participants have the minimum capability to execute the service. The next stage should then concentrate differentiation on aspects that actually change the result: understanding of the scope, methodology, key team, work program, risk management, governance and other previously defined criteria.

How to size requirements without turning prequalification into an entry barrier

The greatest technical risk of the procedure is defining a filter more restrictive than the scope requires. Prequalification should not select the “strongest” companies in the abstract; it should identify which interested parties have sufficient conditions to compete for a particular procurement or procurement program.

Therefore, each requirement should be connected to a concrete risk or responsibility. If the Administration requires prior experience with a given technology, capability or project size, it needs to demonstrate why that requirement is relevant to executing the scope. Criteria that merely reproduce characteristics of known suppliers may restrict competition without increasing procurement security.

A useful methodology is to classify each requirement using four questions:

1. Is the requirement directly connected to a relevant portion of the scope?
2. Is there objective and verifiable evidence to prove compliance?
3. Is the required level proportionate to contractual risk?
4. Could companies capable of executing the contract be excluded without a corresponding technical gain?

If the answer to the fourth question is yes, the requirement deserves review. Excessively closed prequalification reduces one of the instrument’s advantages: forming a competitive universe of capable suppliers over time.

Requirement	Good practice	Sign of excess
Technical experience certificate	linked to relevant portions of the scope	requiring an identical scope in every detail
Number of experiences	minimum sufficient to prove capability	scoring or requiring an unlimited quantity
Previous project size	compatible with scale and risk	requiring a prior contract practically identical to the future one
Team	functions that are genuinely critical	tying up a large team before any contract exists
Certifications	when linked to a concrete technical requirement	generic certificates unrelated to the scope
Financial capability	proportionate to obligations and exposure	ratios or amounts without technical justification

Governance of permanently open prequalification

§2 of art. 80 requires the procedure to remain permanently open for registration by interested parties. This changes management of the instrument. It is not a matter of opening a short window, forming a closed list and using it indefinitely. The Administration needs to operate a continuous process of entry, analysis, updating and publicity.

Documents submitted must be examined by the designated agency or committee within a maximum of 10 business days. The Law also allows correction or resubmission to be required when necessary, with the objective of expanding competition. This favors a logic of curing defects and progressive qualification rather than automatic exclusion for correctable formal defects.

In addition, the maximum validity of prequalification is one year and cannot exceed the validity of the documents submitted. The list of capable interested parties therefore requires document governance. Certificates, registrations, relationships and other documents with their own validity periods cannot be treated as valid merely because the initial prequalification decision has not yet reached one year.

Routine	Recommended control
New registrations	permanently available channel
Protocol	date, interested party, segment and documents received
Analysis	legal deadline of up to 10 business days
Correction	record of corrections or resubmissions requested
Decision	reasoned statement of requirements met and not met
Publicity	updated list of prequalified participants
Document validity	expiration alerts and updates
Segmentation	classification by specialty when used

This control becomes even more important when the future procurement will be restricted to prequalified participants. An outdated list may exclude a supplier that should remain capable or admit a company whose condition no longer exists. Future restriction is defensible only if the previous procedure is current, public and accessible to new interested parties.

Detailed example: multi-year public works and engineering systems program

Consider an agency with a four-year plan to modernize administrative buildings, involving electrical installations, electronic security, structured cabling, automation, HVAC and civil adaptations. Instead of repeating the entire technical-capability analysis in each notice, the Administration may study creating prequalification by segment.

One possible design would form separate groups for electrical installations, electronic systems, telecommunications infrastructure and civil works. Each group would have requirements proportionate to the corresponding responsibilities. A company could be prequalified in more than one segment if it demonstrated capability.

A future Electronic Security procurement, for example, could be restricted to integrators prequalified in that segment. This would not mean declaring in advance which company has the best proposal. The procurement would still need to compare responses to the Basic Design, methodology, team, solution, schedule and price according to the adopted award criterion.

The gain is to move stable checks into a genuinely qualified technical registry. The procurement stops spending effort rediscovering whether each participant has registration, minimum experience and basic capability, and concentrates analysis on what differentiates proposals for that specific project.

This model also creates useful planning information. If only two companies can prequalify in a given segment, the Administration identifies a possible market restriction in advance. It can then review requirements, conduct market consultation, increase publicity or reconsider the strategy before launching a critical procurement.

How to audit whether prequalification is actually increasing efficiency

The instrument is worthwhile only if it reduces administrative effort and increases process quality without unduly reducing competition. For this reason, recurring programs should be monitored with simple indicators.

• number of interested parties registered by segment;
• average analysis time for applications;
• percentage of correction requests;
• number of companies effectively prequalified;
• average number of participants in restricted procurements;
• time saved in the qualification phase;
• appeals or challenges related to qualification criteria;
• contract performance of selected companies.

If the number of participants continuously falls, if the same requirements generate recurring challenges, or if prequalification does not reduce procurement time, the procedure needs to be reviewed. The objective is not to maintain a permanent list for its own sake; it is to improve the Administration’s ability to select capable suppliers with competition and predictability.

Final considerations

Prequalification under Law 14,133 is a tool for organizing the market and rationalizing procurement. In public works and engineering services, it can be especially useful when the Administration has recurring programs and needs to assess companies with compatible technical capability in advance.

Its benefit, however, depends on careful design. The procedure must remain open, use proportionate criteria, be updated, respect document validity and separate minimum capability from technical scoring.

When well structured, prequalification reduces rework and allows future procurements to focus effort on what actually differentiates each contract. When poorly structured, it may simply bring restrictions forward and replicate them across multiple procurements.

Frequently asked questions

What is prequalification under Law 14,133?

It is a selective procedure prior to procurement intended to verify, totally or partially, qualification conditions of interested parties or technical and quality requirements for goods.

Does prequalification replace procurement?

No. It is an auxiliary procedure. Contracting normally depends on a subsequent procurement, except for other independent legal cases.

Can prequalification be used for public works?

Yes. The Law allows bidders to be prequalified for a future procurement or for procurements linked to objectively defined works or services programs.

How long is prequalification valid?

For no more than one year and never for a period longer than the validity of the documents submitted. The status may be updated at any time.

Can new companies join later?

Yes. The procedure must remain permanently open for registration by interested parties while it is in force.

Can the future procurement be limited to prequalified participants?

Yes. Art. 80, §10 allows the subsequent procurement to be restricted to prequalified bidders or goods, but the decision must be technically justified and must not unduly restrict competition.

Are prequalification and qualification the same thing?

Prequalification brings forward the total or partial analysis of qualification requirements. Qualification remains a legal function of the procurement process, even when some conditions have already been verified beforehand.
