Defines the guidelines for governance of professional responsibilities in engineering.
Technical responsibility is the axis that authenticates the quality and safety of our services. As a high-level consultancy, we operate under the supervision of legally qualified professionals, ensuring compliance with all obligations before regulatory bodies.
Professional Qualification: Technical activities performed exclusively by qualified engineers and technicians.
Technical Responsibility Annotation (ART): Mandatory issuance as legally required for each project or service.
Ethics and Conduct: Professional conduct in conformity with the resolutions of the CONFEA/CREA system.
The policy manifests in the rigor of issuing ARTs and in continuous technical supervision throughout the project lifecycle – from Assessment to Operation. This ensures technical traceability and legal security for our clients and the venture.
The guidelines are based on Federal Laws No. 5,194/1966 and No. 6,496/1977, which regulate the practice of engineering professions and establish the Technical Responsibility Annotation.
A3A's technical management performs periodic audits on technical responsibility records and ensures the updating of professional competencies of our technical staff.
A3A Engenharia de Sistemas assumes technical responsibility not merely as a legal obligation, but as an ethical commitment to the safety of society and the technical success of our clients.
