1 MONITORING ON TUNNEL CONSTRUCTION IN CZECH REPUPLIC

2 1. DESIGN  monitoring dimensions and instrumentation 2. MONITORING OFFICE  data operating (archiving, sharing)  measurement interpretation - results 3. MONITORING PANNEL  monitoring conclusions (1 per week min.)  design and technology back analyses 4. SPECIAL MODE  building under passing  public relation and cooperation with building's users Monitoring

3 1.HIGHWAY TUNNELS  Valík (D5 - Plzeň)  Panenská (D8 – Krušné Hory)  Libouchec (D8 – Krušné Hory)  Klimkovice (D47 – Ostrava) 2.RAILWAY TUNNELS  Krasíkov I a II (3. Transit corridor)  Malá Huba, Hněvkovský I, II (3. Transit corridor)  The New Junction (Prague)  Březno (Chomutov) 3. METRO  Line IV.C 4.PILOT TUNNELS  Prague’s highway ring  Brno’s road inner ring
