Special Engineering Services under Brazil’s Law 14,133: When to Use Competitive Bidding, Non-Competitive Procurement or a Waiver

Understand how to procure special engineering services under Brazil’s Law 14,133: competitive bidding, technique and price, non-competitive procurement, waivers, ETP, criteria and classification risks.

A special engineering service is not a procurement procedure and does not, by itself, authorize direct contracting. Under Law 14,133/2021, it is an engineering service that, because of its high heterogeneity or complexity, cannot be classified as a common engineering service. The technical classification of the scope is only the first step; after that, the Public Administration must still determine which legal procurement route applies.

If viable competition exists, procurement of a special engineering service will normally be structured through competitive bidding (concorrência), the procedure expressly provided for public works and both common and special engineering services. The award criterion does not arise automatically from the word “special”: lowest price, greatest discount, technique and price, or best technique depend on the nature of the scope, its value, the relevance of technical quality and the specific rules of Arts. 36 and 37. In 2026, the updated threshold under Art. 37, § 2 is R$ 392,952.63 for the predominantly intellectual specialized technical services indicated there.

Non-competitive procurement (inexigibilidade) only becomes relevant when competition is unfeasible and the requirements of Art. 74 are demonstrated. Under item III, it is not enough for the service to be complex or special: it must be a predominantly intellectual specialized technical service, the professional or company must have recognized expertise, and that expertise must be essential and demonstrably appropriate to fully satisfy the scope. Waiver of bidding (dispensa), by contrast, derives from the objective cases in Art. 75 — including, when applicable, the value-based waiver — and likewise does not arise merely from classification as a special service.

The practical answer is therefore this: a special engineering service may be procured through competitive bidding, non-competitive procurement or a bidding waiver, but each route depends on distinct legal prerequisites that must be demonstrated in the procurement file. Treating “special” as synonymous with “non-competitive” is an error; treating every special service as though technical quality had no effect on the outcome can also be an error. Planning should begin with the actual nature of the need, scope maturity and the value that technical quality adds to the expected result.

A special engineering service is not synonymous with direct contracting

Law 14,133 separates concepts that are frequently mixed in administrative practice. Art. 6, XXI defines an engineering service as an activity intended to obtain an intellectual or material utility of interest to the Public Administration, not classified as a public work, and reserved to engineering, architecture or specialized technical professions. Within this category, the law creates two classes: common engineering services and special engineering services.

A common engineering service involves actions that can be objectively standardized in terms of performance and quality, especially maintenance, adjustment and adaptation of movable and immovable assets while preserving their original characteristics. A special engineering service, by contrast, is one that, because of high heterogeneity or complexity, does not fit that definition.

This classification answers one question: can the scope be treated as a common engineering service, or do heterogeneity and complexity prevent that classification? By itself, it does not answer the next questions: is competition viable? Should technical quality be scored? Is there a case for a bidding waiver? Is recognized expertise indispensable? Which procurement procedure should be used? Which execution regime? Which qualification requirements are proportionate?

This is why classification must originate in the preparatory phase. The article on Common vs. Special Engineering Services examines the classification in depth. Here, the focus is the next step: what the Public Administration should do after concluding that the scope is a special engineering service.

The figure highlights an essential point: classification as special opens a decision stage; it does not close the process.

Competitive bidding is the natural procurement route for special engineering services

Art. 6, XXXVIII defines competitive bidding (concorrência) as the procurement procedure for special goods and services and for public works and both common and special engineering services. Art. 29 reinforces that the electronic auction procedure (pregão) is used when the scope has performance and quality standards that can be objectively defined through usual market specifications, and excludes engineering services from pregão, except for common engineering services.

Accordingly, when the Public Administration reaches a reasoned conclusion that the scope is a special engineering service, the immediate consequence is to rule out pregão as the ordinary procurement procedure. If competition exists and no direct-contracting case applies, competitive bidding becomes the reference procurement route.

This does not mean that every competitive-bidding process for special services is the same. The procedure defines the process, but the procurement outcome also depends on other decisions:

• award criterion;
• bid-dispute method;
• qualification requirements;
• whether the scope should be divided into lots;
• execution regime;
• risk allocation matrix;
• estimated budget;
• performance requirements;
• scope and deliverables;
• measurement and acceptance criteria.

A poorly defined special service remains a poorly prepared procurement, even when the procedure is formally correct. Legal classification does not replace scope engineering.

Competitive bidding does not necessarily mean technique and price

This is one of the points that creates the most confusion. Competitive bidding allows different award criteria. Law 14,133 provides for lowest price, greatest discount, best technique or artistic content, technique and price, and greatest economic return, depending on the scope and applicable legal conditions.

For public works and special engineering services, Art. 36, § 1, IV expressly includes this category among the scopes for which technique and price may be selected when the ETP demonstrates that evaluating and weighting technical quality above the minimum is relevant to the intended purposes.

The correct reasoning is therefore not “it is special, therefore technique and price.” The question is: are there differences in methodology, team, experience, solution, integration capability or technical approach that, above the minimum qualification threshold, produce a measurable impact on the outcome?

If the answer is yes, technique and price may be appropriate. If not, the Public Administration should justify why competition can be resolved by price or discount without a material loss of quality.

The ETP should justify why the service is special and how that changes the strategy

The Preliminary Technical Study is the natural place to organize this decision. It should characterize the public need, analyze alternatives and demonstrate why the selected solution is viable. For special engineering services, it should also record the characteristics that prevent classification as a common engineering service.

The justification should not be limited to expressions such as “complex service,” “specialized scope” or “requires an engineer.” Complexity must be demonstrated by facts. Examples include:

• multiple disciplines with relevant interfaces;
• need for diagnosis and technical judgment under non-repetitive conditions;
• an operating environment that constrains execution methods;
• a high degree of customization;
• need for integration with existing systems;
• wide variability in possible solutions;
• material impact of methodological decisions on schedule, cost or performance;
• reliability, availability or safety requirements beyond usual market specifications;
• need for technical coordination among solutions from different suppliers;
• field uncertainty requiring investigation and controlled adaptation.

The ETP should also answer whether technical quality must participate in the selection or merely operate as a minimum qualification threshold. This distinction is strategic. Requiring minimum experience is different from awarding points for the relative quality of teams, methodologies and deliverables.

The page on Preliminary Technical Studies for Public Works and Engineering Services shows how this stage can be structured to convert an administrative need into a technically defensible procurement strategy.

How to choose the award criterion

After classifying the service and defining the procurement procedure, the Public Administration must determine how proposals will be compared. This decision should avoid two extremes: turning every complex service into a résumé competition or reducing services in which quality is decisive to a purely economic competition.

Lowest price or greatest discount

These criteria may be appropriate in competitive bidding when the scope, although special, is sufficiently defined and the additional quality of proposals exceeding the minimum requirements does not produce a material difference for the public interest. In that case, engineering must specify precisely the standard that every bidder is required to deliver.

The more the outcome depends on creative decisions, methodology, integration, specific experience or team composition, the weaker the premise becomes that all technically qualified proposals are equivalent.

Technique and price

Art. 36 provides for technique and price when the ETP demonstrates the relevance of evaluating and weighting the technical quality of proposals above the minimum requirements. The listed scopes include predominantly intellectual specialized technical services, services dependent on sophisticated technology, special ICT goods and services, public works and special engineering services, and scopes that allow alternative solutions with measurable effects.

The technical proposal may account for up to 70% of the weighting. This does not mean points can be distributed freely. The criteria must relate directly to expected performance and avoid merely decorative requirements.

A coherent scoring matrix may assess, as applicable:

• understanding of the problem;
• methodology;
• work plan;
• experience applicable to the scope;
• qualifications of key professionals;
• interface-management strategy;
• risk approach;
• quality of the proposed deliverables;
• verification and quality-control plan;
• team organization.

Best technique

Under the best technique criterion, price does not compete in the ranking. Law 14,133 provides that the evaluation considers technical proposals exclusively, while the tender documents establish in advance the prize or remuneration to be awarded to the winner. The criterion may be used for designs and work of a technical, scientific or artistic nature.

This differs from technique and price, where the Public Administration calculates a final score by weighting the technical and economic proposals. As a rule, technique may represent up to 70% of the score. For certain procurements, however, Art. 37, § 2 establishes a stronger rule: technique ceases to be merely a modeling option and becomes a mandatory component of the award decision.

Above R$ 392,952.63: when technical evaluation becomes a legal requirement

The amount of R$ 392,952.63, effective in 2026 under Decree 12,807/2025, is not a procurement ceiling, a non-competitive-procurement threshold or a bidding-waiver threshold. It is the updated amount under Art. 37, § 2 and operates as a statutory trigger for the award criterion in certain procurements.

The rule is express and mandatory. Except in cases of non-competitive procurement, when the Public Administration tenders a predominantly intellectual specialized technical service falling under items “a”, “d” or “h” of Art. 6, XVIII and the estimated value exceeds R$ 392,952.63, the award criterion must be best technique or technique and price. If technique and price is selected, the technical proposal must carry a mandatory 70% weighting.

• Item “a”: technical studies, planning, basic designs and detailed designs.
• Item “d”: inspection, supervision and management of public works and services.
• Item “h”: quality and technological controls, analyses, tests and field and laboratory testing, instrumentation, monitoring of specific parameters of public works and the environment, and other engineering services that fall within the statutory definition.

Accordingly, this is not merely a recommendation from the Brazilian Federal Court of Accounts (TCU). The command is in Law 14,133 itself. The TCU interprets and oversees its application, but the obligation originates in Art. 37, § 2.

Situation	Effect of Art. 37, § 2
Detailed design worth R$ 250,000	The value alone does not trigger the specific mandatory rule in § 2. The Public Administration must still analyze the nature of the scope and the appropriateness of technique and price under the other provisions of the Law.
Detailed design worth R$ 500,000, with viable competition	If a competitive procurement is conducted, the award must be based on best technique or technique and price; under technique and price, technique carries a 70% weighting.
Construction management worth R$ 800,000, with viable competition	The same mandatory rule applies, provided the scope is predominantly intellectual and falls under item “d”.
Service falling under Art. 74 with demonstrated infeasibility of competition	The R$ 392,952.63 amount does not prevent non-competitive procurement. Art. 37, § 2 expressly excepts cases of non-competitive procurement.

This distinction is decisive. A R$ 500,000 design contract cannot be taken to a lowest-price competitive procurement if it falls within the conditions of Art. 37, § 2. Conversely, there is no reverse rule stating that a design below R$ 392,952.63 must be competitively tendered or cannot be procured through non-competitive procurement. The threshold governs the award criterion in a competitive procurement; non-competitive procurement depends on the specific prerequisites of Art. 74 and on infeasibility of competition.

This rule deserves separate analysis because it is not enough to know that technique must be evaluated: it is necessary to define what to score, how to grade scores, how to separate qualification from technical scoring, how to structure the evaluation panel and how to combine technique and price without creating subjective or steering criteria. The article Best Technique vs. Technique and Price under Law 14,133: When to Use Them, How to Score and Practical Examples examines this modeling in detail, with matrices, rubrics, an economic-score formula and complete ranking examples.

Special engineering services and predominantly intellectual services may overlap

The “common vs. special” classification looks at standardization, heterogeneity and complexity of the engineering service. The category “predominantly intellectual specialized technical service,” under Art. 6, XVIII, instead looks at work such as studies, planning, designs, opinions, consulting, inspection, supervision, management, quality controls, analyses, testing and other technical activities.

The categories are not synonymous, but they may overlap. A complex design procured by scope may be a special engineering service and, at the same time, a predominantly intellectual specialized technical service. A highly heterogeneous special maintenance service may not belong to the same intellectual group. And, under recent TCU case law, even activities performed by engineers that generate reports, inspections and technical support may, under a staffing-based contracting model, be considered common services when the procured scope is objectively standardizable.

This nuance became particularly relevant in 2026. In Decisions 25/2026, 987/2026 and 2,045/2026, the TCU examined technical-support contracts based on staffed positions and highlighted the distinction between procuring standardizable workforce capacity and procuring a technical product by scope where technical quality is decisive.

By contrast, Decision 28/2026, concerning BIM design development, reinforced application of technical-evaluation rules when the procurement is effectively for design services and the intellectual nature is predominant.

The article Special Engineering Service vs. Predominantly Intellectual Specialized Technical Service examines this conceptual boundary specifically and complements this content.

The diagram shows why it is unsafe to try to resolve the procurement strategy with a single label.

When non-competitive procurement may enter the analysis

Non-competitive procurement is not a discretionary alternative to competitive bidding. It depends on infeasibility of competition. Art. 74 presents illustrative cases and, in item III, governs procurement of predominantly intellectual specialized technical services from professionals or companies with recognized expertise.

The TCU summarizes three requirements for this case:

1. the service must be a predominantly intellectual specialized technical service;
2. the contractor must possess recognized expertise;
3. it must be demonstrated that the work of that professional or company is essential and demonstrably appropriate to fully satisfy the scope.

Law 14,133 removed the former requirement of “singularity” from the statutory text, but it did not turn non-competitive procurement into a general authorization to hire any specialized consultancy. The Public Administration remains required to demonstrate why competition cannot adequately select the provider in light of the concrete characteristics of the service.

Complexity is not the same as infeasibility of competition

A service may be extremely complex while a market still exists with several providers able to compete on objective terms. In that scenario, competitive bidding may be entirely viable.

Complexity may justify:

• classification as a special service;
• differentiated technical requirements;
• technique and price;
• prequalification;
• a more robust ETP and Terms of Reference;
• a more detailed risk matrix;
• technical evaluation of proposals.

But by itself it does not demonstrate that competition is infeasible.

Recognized expertise is also insufficient by itself

A company may have an excellent reputation, an experienced team, publications, relevant cases and differentiated technical capabilities. That demonstrates qualification, but non-competitive procurement requires an additional step: why do those characteristics make its work essential and demonstrably appropriate to fully satisfy that specific scope?

The connection between the need and the contractor must appear in the procurement record. The article Recognized Expertise under Law 14,133 explains in detail how this demonstration should be built.

The scope must be defined before selecting the provider

A technically mature direct contracting process does not start with a company name and then search for reasons to hire it. It begins with the need, expected results, requirements and the reasons why differentiated expertise is indispensable.

This sequence reduces steering risk and produces a more defensible rationale:

public need → scope → differentiated characteristics → expected result → need for specialization → provider analysis → justification of selection → price justification.

The Art. 72 process must document the mandatory elements of direct contracting. The article Direct Contracting under Law 14,133: How to Build the Art. 72 Procurement File organizes that documentation.

When a bidding waiver may be used for a special engineering service

A bidding waiver and non-competitive procurement are different legal mechanisms. Under non-competitive procurement, competition is infeasible. Under a waiver, competition may even be possible, but the legislature has authorized direct contracting in specific circumstances.

For special engineering services, the case most often remembered is the value-based waiver under Art. 75, I. Decree 12,807/2025, effective in 2026, updated the threshold to R$ 130,984.20 for public works and engineering services or motor-vehicle maintenance services.

The amount, however, should not be analyzed in isolation. The Public Administration must observe the applicable rules on calculation, aggregation, improper splitting, publicity and documentation of direct contracting.

In addition to the value-based case, Art. 75 contains other waiver situations that may, depending on the circumstances, reach engineering scopes. The conclusion must arise from the concrete statutory case, not from an attempt to fit the scope into a form of direct contracting desired in advance.

A special service below the threshold does not cease to be special

The technical nature of the scope does not change because the amount is low. A highly specialized diagnosis, a specific test or a complex assessment may remain special engineering services even when the amount allows a waiver.

This means the waiver eliminates the competitive procedure, but does not eliminate the duty to specify properly, estimate price, justify the solution, verify qualification and technically manage execution.

A value-based waiver should not become a splitting strategy

Artificially dividing an integrated demand into small contracts to remain below the threshold technically fragments the scope and may constitute improper splitting. In engineering, this practice also creates additional risks:

• interfaces with no accountable owner;
• incompatible criteria;
• duplicate mobilization;
• loss of a system-level view;
• scope gaps;
• difficulty assigning responsibility;
• higher total cost.

Annual planning and the ETP help identify aggregate demand before selecting the procurement approach.

How to distinguish competitive bidding, non-competitive procurement and a waiver in practice

The decision can be structured as a sequence of questions.

Question	If the answer is yes	Main consequence
Is the scope a special engineering service?	There is heterogeneity/complexity incompatible with a common service	Pregão is ruled out
Is viable competition available?	There are multiple providers and objective comparison is possible	Structure competitive bidding
Is quality above the minimum relevant?	Methodology/team/experience affect the outcome	Evaluate technique and price
Is it a predominantly intellectual service under items a, d or h above the Art. 37, § 2 threshold?	The specific statutory rule applies	Best technique or technique and price, except for non-competitive procurement
Is competition infeasible under Art. 74?	The requirements are demonstrated	Non-competitive procurement may apply
Is there an objective case under Art. 75?	The statutory conditions are met	A bidding waiver may apply

The table does not replace the entity’s legal analysis, but it avoids the methodological error of choosing the procedure first and classifying the scope afterward.

The Terms of Reference must reflect the classification made in the ETP

A recurring problem arises when the ETP treats the scope as complex but the Terms of Reference describe it as if it were a standardized activity. Or the reverse: the Terms of Reference accumulate sophisticated requirements, rare professionals and intellectual deliverables while the procurement process insists on a classification that assumes technical equivalence among proposals.

The documentation should tell one consistent technical story.

The Terms of Reference should materialize:

• scope;
• deliverables;
• functional and performance requirements;
• responsibilities;
• interfaces;
• assumptions;
• measurement criteria;
• acceptance criteria;
• documentation obligations;
• minimum team, when necessary;
• review milestones;
• tests and verifications;
• risk matrix, when applicable.

The more special the service, the more important it is to separate a minimum requirement from an attribute that will be scored. If everything is mandatory, there is no real room to differentiate technical quality. If almost nothing is mandatory and many points are subjective, the evaluation may lose objectivity.

The preparation of Terms of Reference for Public Works and Engineering Services organizes this requirements layer before the tender documents are published.

Qualification should not be used to replace technical evaluation

When the public manager realizes that the service is complex, there is a tendency to increase qualification requirements in an attempt to guarantee quality. This requires care.

Qualification answers whether a bidder has the minimum capability to contract. Technique and price, when applicable, compares the relative quality of proposals that have already exceeded that minimum. Using excessive qualification requirements to select the “best” provider may restrict competition without producing a transparent evaluation of technical quality.

Requirements for certificates of past performance, minimum quantities, key professionals, professional-council registrations and specific experience must be proportionate to the most relevant portions of the scope and to the actual procurement risks.

For special services, it is useful to separate three layers:

1. minimum company capability to participate;
2. capability of key professionals when personal performance is relevant;
3. additional proposal quality when it should be scored.

The procurement documents should make clear which layer each requirement belongs to.

Tender review should verify consistency between engineering and procurement

Before publication, an independent review should verify whether the scope classification, procurement procedure, award criterion, qualification requirements and contract form a coherent system.

Typical inconsistencies include:

• the ETP classifies the scope as special, but the tender uses pregão;
• the Terms of Reference describe a predominantly intellectual scope-based service, but the process treats it as standardized staffing without justification;
• technique and price is adopted without demonstrating the relevance of the scoring criteria;
• lowest price is used even though relative quality is decisive to the outcome;
• technical qualification requires disproportionate experience;
• the scoring criterion rewards company size rather than proposal quality;
• the risk matrix transfers uncertainties that should have been resolved during planning;
• measurement pays for professional presence even though the scope was defined by deliverables;
• the execution regime is inconsistent with the degree of scope definition.

These failures appear before the competition, but their costs usually arise later: challenges, failed procurement, unfeasible proposals, change orders, claims, low quality or stoppage.

The Technical Review of Tender Documents and Annexes for Engineering Procurement focuses precisely on consistency among the ETP, Terms of Reference, design, budget, qualification, award criteria, measurement, inspection and acceptance.

How to evaluate proposals for special engineering services

When procurement reaches the external phase, the Public Administration must evaluate the proposal according to the architecture it created. In complex scopes, small technical inconsistencies can have major effects during execution.

The analysis may include:

• methodology compliance;
• schedule consistency;
• coherence between team and workload;
• compatibility of prices with the resources required;
• feasibility;
• compliance with performance requirements;
• technical-operational capability;
• technical-professional capability;
• consistency of manufacturer and supplier documents;
• compliance with the responsibility matrix;
• treatment of exceptions and deviations.

Under technique and price, the evaluation panel must apply criteria defined in advance. Under lowest price or greatest discount, the technical team remains necessary to verify compliance and feasibility; an economic award criterion does not turn the analysis into a purely mathematical comparison.

Technical Support for Engineering Procurement and Proposal Evaluation provides technical support to the Public Administration in reviewing proposals, qualification documents, deviations, clarification requests and recommendations.

The contract must preserve the logic used to select the provider

Procurement does not end with contract award. If technical quality was relevant to selecting the proposal, the scored technical commitments must carry into the contract and remain verifiable during execution.

It makes no sense to award high scores to key professionals and then allow their replacement without control. Nor does it make sense to score methodology, work plans or differentiated resources and later measure only hours of attendance without verifying the promised deliverables.

The contract must convert the winning proposal into auditable obligations:

• the team actually mobilized;
• deliverables and revisions;
• applicable methodology;
• indicators;
• deadlines;
• approval milestones;
• documentation;
• decision traceability;
• change management;
• acceptance criteria.

This continuity is especially important for special services because much of the contracted value lies in applied knowledge and decision quality, not only in the physical quantity of services performed.

Owner’s Engineering helps preserve technical intent during execution

For higher-criticality projects, the Public Administration may need an independent technical layer to monitor whether the contract is producing the result for which it was structured.

Owner’s Engineering can support:

• technical governance;
• interface control;
• deliverable review;
• RFI management;
• change evaluation;
• risk monitoring;
• technical inspection;
• test verification;
• document management;
• acceptance.

Its role is not to replace the institutional responsibilities of the public manager or inspector, but to provide specialized technical capability for decisions requiring integration among design, contract and execution.

Owner’s Engineering is an alternative for projects in which the Public Administration needs to preserve independent technical governance throughout the implementation lifecycle.

Classification errors that most weaken procurement

Calling a service special merely because engineers are involved

The profession of the person performing the work does not automatically determine the classification. The law looks at the nature of the scope. The TCU’s 2026 case law on staffed positions for engineers and architects reinforces this point.

Calling it common in order to use pregão

The reverse movement is also problematic. If heterogeneity and complexity prevent objective standardization, artificially simplifying the scope to fit it into pregão may compromise both selection and execution.

Calling it special to justify non-competitive procurement

A special service and non-competitive procurement belong to different legal planes. The first is a technical classification; the second is a form of direct contracting based on infeasibility of competition.

Using résumés as the only evidence of quality

Experience matters, but proposal quality may also involve methodology, understanding of the scope, risk strategy and organization of the work. Scoring based only on credentials may fail to distinguish actual capability for the specific scope.

Copying requirements from another tender

Qualification and award criteria should arise from the risks and characteristics of the current scope. Copying a template may import restrictions or scoring rules without justification.

Confusing low price with efficiency

For intellectual or highly complex services, price reductions may mean an insufficient team, shallower analysis, fewer site visits, compressed schedules or superficial deliverables. Feasibility must be assessed against the actual scope.

Decision roadmap for public managers

A robust workflow can be summarized in ten decisions:

1. define the public need and expected outcome;
2. describe the engineering utility to be procured;
3. separate public works from engineering services;
4. determine whether the service is common or special;
5. assess whether the work is predominantly intellectual;
6. verify whether viable competition exists;
7. test statutory cases for direct contracting;
8. if competitive procurement is required, define the procedure and award criterion;
9. structure qualification, measurement, risks and the contract;
10. review consistency among all documents before publication or authorization of direct contracting.

The main advantage of this sequence is that it prevents the decision from being reversed. The procedure should not be chosen before the scope is understood.

Checklist before authorizing the procurement

Before the final decision, the procurement file should be able to answer, with documentation:

• why the scope is a service rather than a public work;
• why it is special rather than common;
• which heterogeneity or complexity factors support that classification;
• whether it is also a predominantly intellectual specialized technical service;
• whether competition is viable;
• why competitive bidding, non-competitive procurement or a waiver is legally appropriate;
• which award criterion applies and why;
• whether technical quality above the minimum changes the public outcome;
• which requirements are qualification requirements and which are scoring criteria;
• how the price was estimated;
• how feasibility will be verified;
• which technical commitments must become contract obligations;
• how measurement and acceptance demonstrate the result;
• how risks and changes will be governed.

If these answers are not mature, the issue is not merely documentary. There is a strong chance that the procurement strategy itself is still insufficiently defined.

Final considerations

A special engineering service is a relevant technical classification, but it is not a legal shortcut. It indicates that the scope has heterogeneity or complexity incompatible with the concept of a common service. From that point, the Public Administration must build the procurement strategy.

When viable competition exists, competitive bidding is the natural procurement procedure. The award criterion should reflect the actual importance of technical quality, observing the cases under Arts. 36 and 37. When competition is infeasible and the requirements of Art. 74 are demonstrated, there may be grounds for non-competitive procurement. When a statutory case under Art. 75 exists, a bidding waiver may apply. None of these routes follows automatically from the word “special”.

Procurement quality depends on consistency among need, ETP, classification, procurement procedure, award criterion, qualification, scope, price, risks and contract. For public managers, this consistency matters more than labels: it is what turns the decision into a technically defensible process and increases the likelihood that the service will deliver the expected outcome.

Frequently asked questions

Can a special engineering service be procured through pregão?

As a rule, no. Law 14,133 reserves pregão for common goods and services and, in engineering, for common engineering services. If the scope has been correctly classified as a special engineering service, the ordinary competitive route is concorrência, unless a statutory case for direct contracting applies.

Must every special engineering service use technique and price?

No. Classification as special does not automatically require technique and price. The ETP must demonstrate when technical quality above the minimum is relevant. Art. 37, § 2 also contains specific rules for certain predominantly intellectual specialized technical services above the updated threshold.

Can a special engineering service be procured through non-competitive procurement?

Yes, provided there is an independent legal basis for non-competitive procurement. Under Art. 74, III, it is necessary to demonstrate a predominantly intellectual specialized technical service, the contractor’s recognized expertise and the essentiality of that expertise to fully satisfy the scope, together with infeasibility of competition.

Does complexity alone demonstrate infeasibility of competition?

No. Complexity may justify classification as a special service, technical requirements and technique and price, but non-competitive procurement requires demonstration of infeasibility of competition under Art. 74.

What is the value threshold for a bidding waiver for engineering services in 2026?

Decree 12,807/2025 updated the Art. 75, I amount to R$ 130,984.20 for public works and engineering services or motor-vehicle maintenance services, subject to the other statutory rules on direct contracting and improper splitting.

What is the updated Art. 37, § 2 threshold in 2026?

Decree 12,807/2025 updated the amount to R$ 392,952.63. Above this amount, except in cases of non-competitive procurement, the services listed under items a, d and h of Art. 6, XVIII, when predominantly intellectual, follow the specific award rule in Art. 37, § 2.

Are a special engineering service and a predominantly intellectual specialized technical service the same thing?

No. The first classification arises from high heterogeneity or complexity that prevents classification as a common engineering service. The second is tied to the intellectual nature of certain technical work. The categories may overlap, but they are not equivalent.

Where should classification as a special service be justified?

The rationale should appear in the preparatory phase, especially in the ETP and the documents defining the procurement. The Terms of Reference, tender documents, award criterion and qualification requirements must be consistent with that classification.
