Planner Overhead Lines - Emergency Measures CE30 Vallemaggia+

Canton of Ticino, Vallemaggia and Blenia Valley (see also tender documents)

Swissgrid plans to implement various emergency measures on the existing overhead lines in the Vallemaggia and on the Biasca - Olivone overhead line to enable safe operation of the lines in the coming years. For this purpose, insulator chains must be replaced on all lines and phase and earth cables may need to be re-adjusted to increase ground clearances. Minor repair work and inspection of pylon statics are also planned depending on the line. For two lines, replacement of three resp. four supporting structures is also planned. For the preparation of the construction project including the creation of the PGV file (phase 32) and support during the approval phase (phase 33) as well as optionally for the further phases 41 - 53, engineering services in the field of overhead line planning are required. This call for tenders is intended to procure the corresponding planning services in the overhead lines sector. Further details can be found in the specifications.

In the event of project delays, the execution period will be extended accordingly.
