Summary

Machine-generated summary

ETH Zurich is commissioning the refurbishment of defective expansion joints in the EKZ building, covering the entire energy channel in the centre of the facility. The joints have exceeded their service life and must be renewed so that safe operation can continue. All expansion joints in the EKZ are to be resealed with a suitable sealing compound and, where appropriate, covered with an additional functionally suitable sealing band, for example Combiflex. Areas with heavier water ingress are additionally to be sealed with concrete injections. According to the hazardous materials planner, the sealing mass is not contaminated and can be replaced without extensive protective measures. Access behind existing installations and high temperatures in the energy channel make execution more difficult.

Description

Im ETH Gebäude EKZ (gesamter Energiekanal im Zentrum) sind die Dilatationsfugen undicht und müssen saniert werden. Dies geschieht Aufgrund der überschrittenen Lebensdauer der Dilatationsfugen und damit die Sicherheit für den laufenden Betrieb weiterhin gewährleistet werden kann. Eine Sanierung aller Dilatationsfugen im EKZ ist vorzunehmen. Angaben des Schadstoff-Fachplaners ist die Dichtungsmasse der Dilatationsfugen nicht schadstoffbelastet und kann daher ohne grosse Schutzvorkehrungen ersetzt werden. Die Dilatationsfugen sind fachgerecht mit geeigneter Dichtungsmasse abzudichten und allenfalls mit einem zusätzlichen, der Funktion entsprechenden Abdichtungsbandes (z.B. Combiflex) zu überkleben. Bereiche mit stärkeren Wassereintritten sind zudem zusätzlich mit Betoninjektionen abzudichten. Durch die erschwerten Zugänglichkeiten hinter den bestehenden Installationen und den hohen Temperaturen im Energiekanal wird die Ausführung der Arbeiten erschwert.
