I AREA OF APPLICATION
Project planning for rockfall protection systems is based on detailed investigations carried out by specialist engi-
neering firms that take into consideration the following geo-technical aspects in particular and define the area of
application using these:
•
Previous rockfall events
•
Condition of the rockfall event zone
•
Evaluation of stability conditions across the entire rockfall zone
•
Rockfall frequency
•
Size of the rocks to be caught
•
Trajectories and jump heights of the rocks
•
Kinetic energy calculations
•
Positioning of the structure (local topography taken into consideration)
•
Anchoring conditions
II QUALITY OF THE INDIVIDUAL SYSTEM PARTS
Geobrugg AG, previously the Geobrugg Protection Systems department of Fatzer AG, based in Romanshorn,
Switzerland, has been certified to quality management system requirements (ISO 9001:2008) since August 22,
1995, registered under the number CH-34372. The certifying body is the SQS (the Swiss Association for Quality
and Management Systems), to which IQNet belongs. The Quality Manual provides complete information on how
individual system parts (primary material, commercial products and end products) must undergo extensive testing
to rule out insufficient quality. The corresponding certificates can be found in the appendix.
III FUNCTIONAL CAPABILITY OF THE STRUCTURE SYSTEMS
The functional capability of the system is based on 1:1 rockfall tests carried out and tested in Walenstadt,
SG (Switzerland), in accordance with European Technical Approval Guidelines ETAG 027 "Falling Rock Protec-
tion Kits" and the Swiss guideline for the approval of rockfall protection kits. These 1:1 rockfall tests are carried
out using vertical drops into the middle field of a three-field structure with post spacing of 10 m each with the im-
pact speeds reaching at least 25 m/s. The trials are accepted by notified testing bodies and receive a European
approval known as an ETA (European Technical Assessment) as well as a Swiss test certificate from the Swiss
Federal Office for the Environment (FOEN). This system, the GBE-100A-R, has the approval no.
ETA
– 15/0304 and the test certificate no. S 14-6.
IV QUALITY CONTROL FOR THE INSTALLATION
This System Manual provides detailed information on the planning and installation of the structure.
