Shorter timelines and controlled quality. In our workshop.
In the era of IT infrastructure expansion, time is a critical resource. That's why data center construction is increasingly shifting from construction sites to strictly controlled workshop conditions. Steel structures, complex mechanical installations, and pipework are prefabricated in advance and only then assembled on-site. This approach guarantees significantly faster execution timelines, eliminates downtime, and ensures uncompromising, controlled quality.
Workshop prefabrication and testing
For elements that arrive on-site ready for rapid integration
Welding with complete quality control
Including NDT (Non-Destructive Testing), hydrostatic testing, and strict dimensional control
Mechanical installation and on-site integration
Reliable, safe, and on schedule - directly at your location
International mobilization
Teams and equipment ready for international data center construction projects
For on-site construction, we use elements manufactured in our workshop
Our workshop teams operate daily, and we put all our capacity, expertise, and logistics at the disposal of investors and EPC partners.
Prefabricated mechanical and process pipework (pipe spool)
With special focus on complex cooling and service loops for data centers
Steel structures and support frames
Customized for modular units, server rooms, IT modules, and associated equipment
You design the architecture. We bring it together.
Modular projects demand flawless timing. That's why we take on the entire scope of mechanical works through a single-contractor model. Drawing on 20+ years of experience in industrial and energy construction, our own 4,000+ m² workshop, and a team of 100+ qualified workers, we relocate key fabrication and testing processes to controlled conditions, then ensure rapid mobilization of equipment and teams across Europe.
Certified management systems and welding quality
Our management system is certified according to ISO 9001, ISO 14001 and ISO 45001, while quality management in welding production is carried out in accordance with EN ISO 3834-2. We manufacture products in accordance with project documentation and agreed technical requirements, applying the relevant EN, ISO, ASME and API standards where specified by the project. For pressure equipment, the appropriate conformity assessment procedure is applied in accordance with the requirements of the PED.
Material traceability and controlled production process
Production is carried out using materials defined by project specifications, with identification and traceability from receipt to final delivery. Material documentation, welding, inspection, and testing are recorded in the production dossier.
Fast fabrication, controlled quality, installation anywhere in Europe
Data center and modular unit construction cannot tolerate schedule delays, regardless of location. For clients who want execution without risk, budget overruns, or additional on-site complications, we offer to take on the complete scope of mechanical work. Our approach includes the following.
Single-contractor model
Fixed deadlines and budget
Minimal downtime
Transparency and clear communication
