What is being procured?

Scope of work

Für die Planung des Oberwasserdruckschachtes (ODS) werden detailliertere Kenntnisse der Felsverhältnisse benötigt. Zu diesem Zweck sollen im Sommer 2026 Erkundungsbohrungen ausgeführt werden. Gleichzeitig werden die Bohrungen zur Durchführung von Bohrlochversuchen genutzt.

Die Bohrungen werden aus dem in der Vorinvestition Grimsel 4 bereits realisierten Teil des Triebwassersystems, dem sogenannten Oberwasser-Druckstollen Flachstrecke I (ODF I) abgeteuft. Dabei liegt die aktuelle Tunnelbrust nach Realisierung der Vorinvestition in einer Horizontaldistanz von 50 m zum vorgesehenen Druckschacht. Der Schachtbereich soll mit jeweils einer flacheren und einer steileren Bohrung auf zwei verschiedenen Niveaus untersucht werden.
