Restoration of the 150-kV Bonete–Young High-Voltage Transmission Line
We participated in the restoration of a section of the 150-kV Bonete–Young transmission line, a strategic piece of infrastructure for UTE’s power grid in Uruguay. The project arose after a weather event caused the collapse of several structures located in an area partially flooded by the Baygorria Dam reservoir.

We were commissioned by TEYMA S.A., the company that won the public tender as part of a joint venture, to carry out the structural engineering for the new foundations that would allow the line to resume operation under safe and reliable conditions.

Our work involved the comprehensive design of reinforced concrete foundations of the independent footing type with inclined shafts for five new towers: BON-YOU T078, T079, T080, T081, and T081A. The engineering was carried out taking into account the complex geotechnical conditions of the site, associated with its proximity to the reservoir, and applying the calculation methods required by UTE, including Sulzberger and CIGRE 22-06.

Scope of the project

We provided the complete structural engineering for the foundations of the five towers, including:

  • Design and calculation of reinforced concrete foundations of the independent footing type with a sloped shaft.
  • Structural analysis reports in accordance with UNIT 1050, EHE, and DIN 1045 standards.
  • Preparation of formwork and rebar drawings.
  • Development of detailed engineering designs for construction.
  • Preparation of all technical documentation in digital format for use on-site.

Impact of the Project

Through this project, we are contributing to the restoration of infrastructure that is essential to the country’s electric transmission system. Our engineering expertise enabled us to develop solutions tailored to a highly complex geotechnical environment, ensuring the constructability of the new structures and contributing to the reliability and continuity of the UTE grid’s electricity supply.
