Technical reports and attestations in São Paulo, in a few lines
A technical report is the responsibility of an engineer or architect, each within their own qualifications, and it needs an ART (engineer's Technical Responsibility Record, registered at CREA) or RRT (architect's equivalent, registered at CAU) filed before the work. The most requested in São Paulo are attestations of installations and stability for City Hall, proofs of technical responsibility for the Fire Department, and building inspection under ABNT NBR 16747.

What a technical report is
A technical report is a document signed by an engineer or architect that describes the condition of a property, a structure or an installation, with conclusions and recommendations.
It answers questions like: is the structure safe? Is the leak coming from the neighbor? Does the electrical installation meet the standard? Can the building take the new use? The answer has to be technical and documented.
The report is requested by public agencies, banks, condominiums, insurers and judges. It also helps the owner decide before buying, renovating or selling.
