⌐ 01, THE WOMEN AND MEN
IT IS THE WOMEN AND MEN WHO BUILD THE POWER LINES.
VIATIS brings together linemen, team leaders and site managers specializing in the construction and maintenance of high- and extra-high-voltage (HV/EHV) overhead power lines.
Our job is to carry out the works entrusted to us. We mobilize the necessary skills, organize the teams and coordinate operations in line with the client’s methods and the constraints of the site.
The experience of our teams, their command of technical skills and the quality of their supervision contribute to the proper execution of the works. Safety relies on concrete practices: training, preparation of interventions, compliance with procedures and inspection of the equipment used.
Accustomed to European worksites, our teams integrate into existing organizations. We develop their know-how and pass on experience to maintain this standard.
⌐ 02, Core Expertise
EXPERTISE DEDICATED TO ELECTRICITY TRANSMISSION LINES.
Specialized skills for each project phase.
For almost twenty years, VIATIS has been operating within the electrical grid environment.
Today, the company focuses its activity on the operational execution of HT and THT overhead lines in Europe.
We work alongside grid operators and their main contractors on technical phases that demand precision, coordination, and on-site mastery.
MAINTENANCE AND ADAPTATION OF INFRASTRUCTURES
Reinforcement, modernization, and adaptation of existing electrical grids.
CONDUCTOR WORKS
Stringing, sag adjustment, anchoring, jointing, and compression. Removal and replacement of single or bundled conductors, earth wires, and OPGW/OPPC optical cables. Installation of jumpers, spacers, and dampers, including during complex crossings.
OPERATIONAL SUPPORT FOR LARGE PROJECTS
VIATIS mobilizes teams of linemen and their supervisors for the construction and maintenance of HV/EHV overhead power lines in Europe. Team leaders and site managers organize the operations entrusted to them, in line with the client’s methods and the requirements of the grid. This reinforcement helps you carry out more work and run several worksites in parallel.
⌐ 03, Working Method
A METHODOLOGY ADAPTED TO THE REQUIREMENTS OF EACH NETWORK.
Prepare, coordinate, and control each intervention.
Each project is based on its own methods, standards, and requirements.
VIATIS integrates these from a rigorous preparation stage to ensure controlled execution, regardless of the country of intervention.
Preparation
Anticipate each step, coordinate stakeholders, and secure execution conditions.
Safety
At VIATIS, the safety of people is an absolute priority. It relies on regular training, inspected and audited equipment and tools, and continuous QSE (quality, safety and environment) management, from site preparation through to execution. When the necessary safety conditions are not met, the work is not started or is suspended. The situation is reassessed and the appropriate measures are put in place before the work starts or resumes.
Quality
Guarantee the technical conformity of the works and compliance with project requirements.
Execution Control
Meet safety, quality, schedule, and performance objectives.
Adaptation
Quickly integrate the methods and standards of each grid operator.
Transmission
Share methods and skills to strengthen collective expertise.
