One of the largest data centers in operation in Brazil: +9 MVA, 6 MW of IT load and 240 km of conductors executed by MSE.
Installations
Electrical, fire protection, automation and systems under a single point of responsibility. From the utility connection point to the rack, with our own team and integrated commissioning.
Substation, Medium and Low Voltage
HV/MV substation, transformers, MV and LV switchboards, busway and conductors all the way to the data halls. Power distributed with circuit-by-circuit traceability.
Generators, UPS and Diesel
Generator sets, double-conversion UPS, batteries and diesel storage and distribution. N+1 and 2N topologies, with no single point of failure.
E-Houses and Electrical Switchboards
E-houses, switchboards, PDUs and STSs built and tested in our own factory. They arrive on site ready to connect, shortening the path to first power.
Fire Protection
Sprinklers with pre-action valves, hydrants, pumps, piping networks and firestop sealing. Protection against accidental discharge inside the data halls.
Detection and Gas Suppression
Early aspirating smoke detection, fire alarm systems and clean-agent suppression. Fire is identified and contained before it reaches the IT equipment.
Automation and Monitoring
Integrated PLC, BMS and EPMS, with relay parameterization and real-time supervision of power and alarms.
Electronic Security and Cabling
CCTV, access control, perimeter alarm and structured cabling in accordance with TIA-942 and TIA-568.
Infrastructure and Cable Trays
Cable trays, ladder racks, channels, baskets and conduit runs sized for the data halls. Routes separated by voltage and system, ready for expansion without rework.
Civil Structure and Raised Floor
Slab reinforcement for racks, UPS systems and batteries. Raised floor with a service void for air and cables, or a solid slab with overhead distribution.
Tier III Certification
Experience in Tier III data centers, with concurrent maintainability and redundant paths. Documentation, tests and as-built prepared for Uptime Institute certification.
L1–L5 Commissioning
Current injection, arc flash, selectivity and integrated tests from level 1 to 5. Redundancy proven before first power. References: ASHRAE Guideline 0, Uptime Institute, NFPA 70E.

Modern facilities demand high power density, liquid cooling and advanced safety systems. An integrated partner centralizes responsibility, reduces interfaces and keeps electrical, civil, mechanical, automation and fire protection working together. (In Portuguese.)
Why critical infrastructure cannot fail: redundant power distribution, very early smoke detection and inert-gas suppression in data centers and control rooms. (In Portuguese.)

Our approach to quality and commissioning delivers data centers ready to operate 24 hours a day, 7 days a week, 365 days a year.
At MSE Engenharia, we understand that speed of deployment, reliability and predictability are essential in data center construction. That is why we work in an integrated way, from construction planning through building, assembly, testing and commissioning.
The sequence of a data center build, from the initial study to first power. Each step is detailed in the full guide.
Building a data center is not a civil works job with equipment inside. It is a build in which power and network define the schedule, and in which any mismatch between engineering and execution becomes an availability risk. That is why choosing a data center construction company with its own team changes the outcome.
A data center goes through three phases: engineering (conceptual, basic and detailed), construction and installations (civil, electrical, fire protection and automation) and commissioning through first power. The work begins with the conceptual study, which defines capacity in MW, rack density and electrical topology. Then come basic engineering, detailed engineering and the issue of construction documents. Only then do earthworks, foundations, structure, electrical rooms, substation, diesel system and network come in.
Building a mid-sized data center takes 12 to 24 months, from the initial study to energization. What delays the work most is not the civil works: it is the long-lead equipment, such as transformers, generators and UPS, which can take 8 to 14 months to arrive. Specifying these items during the engineering phase is what protects the schedule.
The cost of a data center is driven by installed electrical power (MW) and by the level of redundancy, not by built area. A 5,000 m² hall with 2 MW and a 5,000 m² hall with 10 MW are completely different jobs. The power infrastructure available at the site and the required Tier level also weigh heavily.
Tier 2 has redundant components, Tier 3 allows any component to be maintained without shutting down the load, and Tier 4 tolerates faults with independent systems. The classification, also written as Tier II, Tier III and Tier IV, is defined by the Uptime Institute. A Tier 3 data center requires redundant power paths; in Brazil, it is the most requested level for colocation data centers. The higher the level, the greater the impact on layout, substation and cost.
In the EPC turnkey model, engineering, construction, assembly and commissioning stay under a single point of responsibility; in separate contracts, each discipline answers only for its own part. Hiring engineering, the builder and the installer separately looks cheaper on paper, but it creates gray areas between contracts, and that is where rework and delays appear. In data centers, turnkey reduces interfaces exactly where availability risk is highest.
We develop solutions for data centers,
from construction to commissioning,
with first power on schedule.
HV/MV substation, transformers, medium- and low-voltage switchboards, busway, generators, UPS and distribution down to the racks — with circuit-by-circuit traceability and commissioning before first power.
Yes. Pre-action sprinklers, hydrants, aspirating smoke detection and clean-agent suppression, all by the same in-house team.
They are five levels of testing, from factory inspection to integrated tests under load. Each system is validated before energization, proving N+1 or 2N redundancy.
Yes. They leave our own factory tested and arrive on site ready to connect, reducing interfaces and shortening the path to first power.
Yes. Hall expansions and system upgrades are carried out with a work plan that preserves the availability of the existing operation.
Sim. A MSE executa instalações para data centers em todo o território nacional, com equipes próprias mobilizadas por obra. Painéis elétricos da fábrica do grupo também já foram fornecidos para data center no México.
Tier III is the Uptime Institute classification for concurrently maintainable data centers: any component can be maintained without shutting down the IT load, which requires redundant power paths.
A five-level testing process, from factory inspection (L1) to integrated tests under load with failure simulation (L5), that proves redundancy before first power.
BMS is the building management system that supervises utilities and alarms; EPMS is the electrical power management system that monitors substation, generators, UPS and switchboards in real time.
Colocation is a data center that leases space and power to multiple customers; hyperscale is a large data center built for a single cloud operator, usually above tens of MW.
