Gotthard BAse tunnel

The project remit covers the whole construction project, including the dimensioning and construction of the traction power installations for the new Gotthard base tunnel line. The construction project serves as a basis for the cost estimation from ATG, the approval procedure and the tender for the electro-mechanical installations.

Following the award of contract to Transtec Gotthard, ENOTRAC supported Transtec Gotthard and ATG during detailed design. A core task included the technical coordination with other engineering disciplines, such as the construction contractor and SBB who are responsible for the high voltage traction power supply. In 2012, the Swiss Federal Office of Transport granted project approval for the traction power supply installation, which meant for us the start of the assembly.

ENOTRAC’s remit was extended to support the equipment contractor during the assembly and monitoring the construction progress. We also supported ATG for project modifications, with RAMS process and coordination with other engineering areas and SBB.

In addition, ENOTRAC is planning and monitoring the commissioning, testing and validation.

The mandate is being conducted under the “IG GoTTrazione” consortium, lead by ENOTRAC in collaboration with Pöyry Schweiz AG.
