? General questions
It is simple and there is no obligation: send us on WhatsApp (34) 98815-8283 your name, a contact phone number, the address of the property or construction site and a brief description of what you need. Eng. Rafael Barreto reviews the case and comes back with a tailored proposal.
No. The documents listed for each service help us be more precise, but they are not mandatory to get started. Send us the information you already have and we will move ahead with your quote.
Every service is tailored to the scope, the complexity and the particulars of each case. That is why the quote is prepared individually by the engineer in charge, once we understand your need — we do not work with a fixed price list.
Yes. We work in Araxá and across the Minas Gerais region. For properties in other towns, just tell us the municipality and the distance — any travel costs are agreed transparently in the quote.
Yes. Every service is carried out under the responsibility of Civil Eng. Rafael Barreto — CREA-MG, with an ART (Technical Responsibility Note) issued whenever applicable.
Six areas: Engineering Design, Technical Reports and Valuations, Surveying and Georeferencing, Technical Studies and Documents, Construction Management and Consulting and Regularization and Permitting — adding up to more than 50 specialized services.
It depends on the scope and, in some cases, on the timelines of public agencies. Procedures such as deed registration (60 to 90 days), AVCB fire safety approval and Federal Revenue Service regularization (15 to 30 days) have their own review periods. The estimate is always stated in the proposal.
Yes. We issue the ART — Technical Responsibility Note for services that require technical accountability, giving your design, report or construction project legal standing.
Absolutely. Tell us your situation — do you have land and want to build? A building to regularize? A structural problem? Do you need a report for a bank or a public agency? From there we point you to the right service. Take a look at our service catalogue.
