Planner Overhead Lines - Emergency Measures CE30 Vallemaggia+
Swissgrid plans to implement various emergency measures on the existing overhead lines in Vallemaggia and on the Biasca - Olivone overhead line to ensure safe operation of the lines in the coming years. To this end, insulator chains must be replaced on all lines and, if necessary, the phase conductors and earth wires must be readjusted to increase ground clearances. Furthermore, depending on the line, minor renovation work and a check of the pylon statics are planned. For two lines, the replacement of three or four support structures is also planned. For the development of the construction project, including the preparation of the PGV dossier (Phase 32) and support during the approval phase (Phase 33), as well as optionally for the subsequent 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 field of overhead lines. Further details can be found in the specification.
