The underground network situation in France
The French territory is covered by 2,5 millions kilometers of underground networks.

2007 and 2008 have been tragic years since 4 severe accidents occurred in Niort, Bondy, Noisy-le-Sec and Lyon.

February 2008 – A gas leak in Lyonduring trenchless works resulted in the death of a
fireman and 40 injured people

In Ghislenghien Belgium, on July 30th 2004 a gas explosion caused 24 death and 132 injured.
Million Euros wasted in human and financial loss

In 2008 : an average of 17 damages per day have been recorded on gas networks
About 50 000 to 100 000 damages to underground networks are recorded per year

Landsurveyors can definitely play a role.

the French new standards for underground works
The French government’s action plan

underground works1. An official request must be done to evaluate the underground networks’ position before any job can start.2. If a minimum of a 40 cm precision of the network’s position can not be proven. Further investigations become mandatory. The job sight must be radar scanned. The ground will have to be properly marked before the intervention of the construction company.3. all new underground networks must be georeferenced.

contenant une puce RFID
• Il pourra être placé parmi les repères géo référencés pour matérialiser l’un des points dans une triangulation et contenir les données

• La puce est conçue pour mémoriser des informationsrelatives aux réseaux souterrains. L’accès à la puce est sécurisé et conditionné par des droits de lecture et d’écriture. La lecture des informations s’effectue en temps réel et permet d’obtenir des renseignements sur les réseaux à proximité comme :

1. La position géo référencée du réseau.
2. Les caractéristiques du réseau (dimensions, matière, type)
3. La position des accessoires du réseau (vannes de coupures, boites de jonction)
4. Le marqueur RFID permet de limiter les sondages préalablesen offrant une connaissance des réseaux in situ. Il peuts’avérer précieux au cours des interventions d’urgence.
