Many projects start with an expensive confusion: “the architect will do the calculations” or “the engineering office will draw the plans”. These are two distinct professions, complementary — and not interchangeable. On PontBat, each one is verified for their exact role, and the technical file is required before any construction money moves.

The architect shapes the space and carries the legal file; the engineering office guarantees the house will stand. Confusing them means signing with the wrong person for the wrong mission.
The architect translates your life into plans: orientation, volumes, light, circulation, fit with the plot. They also carry the legal file: in Tunisia, the building permit is filed with the municipality by an architect who must be registered with the Order of Architects of Tunisia — without them, no admissible file, no legal start. The PontBat reflex: registration with the Order is verified on the CV-profile before any matchmaking, never taken on trust.
The engineering office takes the architect's plans and answers the hard question: how does it hold up? Structural sizing, concrete reinforcement, foundations suited to the actual soil, technical packages — electricity, plumbing, ventilation. Its output is the execution drawings and the structural calculation note: the documents the site will follow line by line. The PontBat reflex: an engineering office named in the contract, with named deliverables — not “a friend's engineer” with nothing in writing.
On PontBat, no structural milestone opens without the execution drawings and the structural calculation note filed in the project record. That is the red line: the escrow releases nothing towards structural work as long as the site has no written technical reference. The contractor builds from documents, not from memory — and every later inspection is carried out against those very documents.
At control points, the engineering office checks that the execution follows its own drawings — and an independent expert co-signs the report. The platform's absolute rule: the expert is never paid by the contractor they inspect; their fee goes through the platform, never through the inspected party. Two signatures, two sets of eyes, zero conflict of interest — and the milestone is only paid on a compliant report.
The most expensive defects are not born on the site: they are born earlier, in a rushed or missing technical file. Four traps come up again and again.
On PontBat, architects and engineering offices present a verified CV-profile: registration with the Order of Architects checked and displayed as a badge — like Atelier Médina, an engineering office of the network —, real references, reviews from real contracts only. You know who signs what, before you sign anything.
Execution drawings and calculation note filed in the record, inspections co-signed by the engineering office and an independent expert, milestone paid on a compliant report: design is not a pre-construction formality, it is the contractual reference for everything that follows. What is calculated gets checked; what is checked gets paid.
They cost nothing before signing — and prevent the mistakes that are paid for in years.
Only an architect registered with the Order of Architects of Tunisia can file your building permit with the municipality. Ask for proof of registration — on the platform, it is checked and displayed on the CV-profile before any matchmaking.
A structural works quote without an attached calculation note is a promise, not a commitment. Require the execution drawings and the calculation note to be named in the contract as deliverables — dated, signed, archived in the file.
A beautiful plan that cannot be built, or a calculation that ignores the architecture: both exist. Check that the architect and the engineering office work on the same, up-to-date documents — inconsistencies between drawings are paid for on site, at a premium.
Ask who will inspect the execution, and who pays them. If the inspector is chosen or paid by the inspected contractor, the inspection is worthless. On the platform, the expert co-signs with the engineering office and is never paid by the inspected party.
Verified architects and engineering offices, a required technical file, co-signed inspections: entrust the design to profiles whose role is proven — or delegate everything, we handle it.
