New Constrcution GLC, ETH Zurich
Geodetic and geotechnical permanent monitoring of a deep excavation pit
The excavation pit for the new ETH research building in Zurich is a technical challenge and contains all the difficulties of special civil engineering, such as pre-stressed diaphragm walls, bored piles with multiple back-anchoring, underpinning with micro piles and jetting, etc.
A construction pit of this depth in a steep slope in the city centre is highly dangerous and its behaviour must be monitored intensively using measurement technology.
Services
- Permanent 3D monitoring of the excavation walls and surrounding buildings
- Installation and operation of geodetic and geotechnical monitoring systems
- Data transmission to the data loggers, partly wired and partly via radio
- Alarm when limit values are exceeded
- Project in collaboration with AFRY Schweiz AG, which carried out crack recordings on the surrounding buildings and manual deformation measurements on buildings and tram rails.
Technologies
- 2 precision total stations with 100 monitoring points
- 9 chain inclinometers, each with 15 sensors (135 sensors in total)
- 6 5-fold extensometers (30 sensors)
- 70 anchor force sensors
- TEDAMOS Web, password-protected customer portal with 24/7 access
