A special engineering service and a predominantly intellectual specialized technical service are not the same category under Law 14,133\/2021.<\/strong> The first concept appears in Art. 6, XXI, \u201cb\u201d, and classifies an engineering service by its high heterogeneity or complexity<\/strong>, that is, by its inability to be classified as a common engineering service. The second appears in Art. 6, XVIII, and identifies technical work centered on studies, planning, designs, opinions, assessments, consulting, inspection, supervision, management, quality controls, analyses, tests and other activities defined there, when the intellectual dimension predominates.<\/p>\n\n\n\n

The two classifications answer different questions. Common vs. special<\/strong> asks how standardizable the engineering scope is. Predominantly intellectual<\/strong> asks about the nature of the technical work and the extent to which the outcome depends on knowledge, analysis, judgment, methodology and professional development. Therefore, the categories may overlap, but one does not automatically follow from the other.<\/p>\n\n\n\n

A multidisciplinary detailed design procured by scope may simultaneously be a special engineering service<\/strong> and a predominantly intellectual specialized technical service<\/strong>. Complex and heterogeneous maintenance may be special without necessarily belonging to the same intellectual core. And procurement of staffed engineer positions may, in some circumstances, be considered a common engineering service even when the allocated professionals produce reports, inspections or support activities listed in Art. 6, XVIII \u2014 a distinction reinforced by the TCU in 2026 decisions.<\/p>\n\n\n\n

The difference matters because it changes procurement strategy. Classification as a special engineering service rules out preg\u00e3o<\/em> as the ordinary route and points to competitive bidding (concorr\u00eancia<\/em>) when a tender is held. Predominantly intellectual work may require or favor technical evaluation, especially under Arts. 36 and 37. Non-competitive procurement, however, does not arise from either label alone: under Art. 74, III, it also depends on recognized expertise, the essentiality of that expertise to satisfy the scope and infeasibility of competition.<\/p>\n\n\n\n

The difference can be understood through two axes<\/h2>\n\n\n\n
\n

When \u201cspecial,\u201d \u201ccomplex\u201d and \u201cintellectual\u201d are treated as synonyms in the procurement process, the procurement procedure and award criterion may be built on a technically incorrect classification. The ETP should separate the two axes and demonstrate what actually characterizes the scope.<\/p>\n\n\n\n

Preliminary Technical Study (ETP) for Public Works and Engineering Services<\/a><\/p>\n<\/div>\n\n\n\n

The safest way to interpret Law 14,133 is to abandon the idea of a single scale on which services progress from \u201csimple\u201d to \u201cspecialized.\u201d The law uses different classifications for different purposes.<\/p>\n\n\n\n

The first axis is standardization, heterogeneity and complexity<\/strong>. This is where common and special engineering services appear. The second axis is the nature of the technical work<\/strong>. This is where predominantly intellectual specialized technical services appear.<\/p>\n\n\n\n

This means the public manager must perform two analyses, not one.<\/p>\n\n\n\n

Axis 1 \u2014 common or special engineering service<\/h3>\n\n\n\n

Art. 6, XXI defines an engineering service and divides it into two categories. A common engineering service consists of actions that can be objectively standardized in terms of performance and quality, especially maintenance, adjustment and adaptation while preserving original characteristics. A special service is one that, because of high heterogeneity or complexity, cannot be classified under that definition.<\/p>\n\n\n\n

The central question is: can performance and quality be defined sufficiently objectively through usual requirements so that competition does not depend on material technical differences among solutions?<\/strong><\/p>\n\n\n\n

The classification does not depend on the commercial name of the service or the professional’s degree. It depends on the structure of the scope.<\/p>\n\n\n\n

Axis 2 \u2014 predominantly intellectual specialized technical service<\/h3>\n\n\n\n

Art. 6, XVIII lists technical work such as:<\/p>\n\n\n\n
