Coordinated before construction, not during it.
Building electrical design is where construction rework most often appears: openings in the wrong place, conduits that do not fit and undersized panels discovered at handover.
The cause is almost always the same: electrical design was produced without coordination with plumbing and structural systems. The conflict existed on paper and no one noticed.
We coordinate it beforehand.
Buildings from the 1980s and 1990s were designed for loads that no longer exist. Today every unit may have air conditioning, the garage may have EV chargers, and showers may draw more power, all supplied through an entrance sized for another era.
We survey the real load, report nonconformities and prepare a phased upgrade design so the condominium can approve and execute the work without shutting down the building.
A construction site has its own temporary electrical installation, inspected like any other. NR-18 requires a design for temporary installations, suitable distribution boards, grounding and protection against electric shock in an environment that changes every week.
This is among the most frequent causes of citations and work stoppages because the installation begins improvised and expands with the project.
We design the temporary site installation and issue the NR-18 compliance report. For builders operating several sites, we provide contract service for each project.
NBR 5410, NBR 5419, NBR 16747, NBR 10898 for emergency lighting, NBR ISO/CIE 8995-1 and NR-18 for construction-site installations.
Describe what you need through the form or WhatsApp, including size and deadline. Attaching a drawing speeds up the process.
We reply within one business day for a short technical conversation to define scope and verify applicable requirements.
We send a proposal stating inclusions, exclusions, price and schedule.
We deliver with the ART issued.
Every project and technical report issued by Maccari is signed by a qualified professional registered with the appropriate professional council, with an ART or TRT duly filed. You know who is technically accountable before hiring us and after delivery.
The technical team includes electrical engineers, occupational safety engineers and electrotechnical technicians, with consolidated experience in 15, 25 and 35 kV networks.
From survey to commissioning, responsibility is registered in the name of the professional who performed the work.
