ART and technical responsibility: who answers for your project

Updated on 07/06/2026 by EZA Engenharia

ART stands for Anotação de Responsabilidade Técnica (Technical Responsibility Record), the CREA document that registers which engineer is accountable for your project. In other words, it's the document that defines who takes responsibility if the structure cracks, if the slab gives way or if the execution deviates from the design. A project without an ART is a project without a technical owner, and that comes at a price in safety, in insurance and even in the property's resale value. Here we explain how technical responsibility works on the project, what the engineer really does on-site and how to check whether your construction is covered.

What the ART actually is

The Technical Responsibility Statement (ART) has existed under federal law since 1977 and is issued through CREA, the Regional Council of Engineering and Agronomy. It records, in a public document, that a qualified engineer has taken on a given service: the structural design, the construction execution, the electrical installations, the plumbing. Each technical service requires its own ART.

When the person responsible is an architect, the equivalent document is called RRT and is issued by CAU. Its purpose is the same: to state, with name, registration number and signature, who answers for that part of the work. If you are still deciding between engineer or architect to build your house, what does not change is this: someone qualified must sign off. It is this record that allows anyone to check with CREA who is behind a project, and that is why a serious job site has a sign with the name of the technical manager clearly visible.

Who answers when something goes wrong

With the ART (technical responsibility record) issued, the engineer is liable both civilly and criminally for what they signed. If the structure develops a problem or an accident occurs due to a technical failure, there is an identified professional, with an active registration, who will have to answer for it. The Civil Code further guarantees the project owner five years of the builder's liability for the soundness and safety of the construction.

Now flip the scenario. On a project run on your own, without a technical manager, you are the one who answers for it. A worker accident, damage to the neighbor's wall, a crack in the structure: it all falls on the owner's lap. The savings that seemed clever at the start turn into a legal risk that most people never factored in.

What you risk by building without a technical lead

The first risk is the most obvious: safety. A foundation sized by eye, too little reinforcement, uncontrolled concrete. A structural problem almost never shows up in the first year. It shows up later, with the house already occupied, when fixing it costs far more than doing it right would have.

Then come the risks nobody sees in the budget. The city hall can halt the project and impose a fine, and CREA also issues citations. Insurers usually deny claim coverage on an irregular construction. Banks won't finance a property without its paperwork in order, and on resale a well-advised buyer discounts from the price everything that's still pending.

• Stop-work order and fine from the city, plus a penalty from CREA
• Insurance that may deny coverage in the event of a claim
• Difficulty registering, financing and selling the property
• Structural problems that only appear years later

What technical responsibility changes in the day-to-day of the project

A real technical manager is not a rented signature. It is someone setting foot on the site: checking the rebar before releasing the concrete pour, coordinating the designs so the electrical work does not clash with the structure, adjusting the schedule when it rains all week.

At EZA, which has been building in Criciúma since 1991, the engineering is in-house and follows the project from design to finishing. Concrete pours have an engineer present, the designs go through coordination before they become a construction site, and the waterproofing is checked with a leak test, that lengthy process of sealing everything, waiting and monitoring to be sure it works.

Safety is part of the same package. On our projects we keep repeating that safety is not a detail, it is a priority. Proper PPE, signage and collective protection are part of the routine of those who are technically responsible for what happens inside the site fence.

How to check whether your project is covered

Before signing a contract, ask for the project's execution ART number. It is a simple request and no serious construction company will mind it. With the number in hand, you can check its status on the CREA of Santa Catarina website in a few minutes.

Also check whether the name on the document belongs to someone who actually oversees the construction site, and not a borrowed registration. And look at the whole set: permit, approved design, land title. The complete list is in our guide to documents and permits to build in Criciúma, and this care adds to the criteria of how to choose a construction company without regretting it later.

• Request the execution ART number before signing the contract
• Check the document status on the CREA-SC website
• Check whether the technical manager actually visits the site

In the end, the ART is not bureaucracy. It is the name of whoever puts their own professional registration on the line for your project. A house is the largest investment for most families, and it deserves an identified responsible party from the first day to the last. EZA Engenharia has been building for over 35 years in Criciúma and the surrounding region with in-house engineering and technical responsibility present on the site, not just on paper.
