THE EVOLUTION OF SURVEY MARKING AND PEGGING

Page 2: The Evolution of Survey Marking and Pegging

The underground network situation in France

The French territory is covered by 2,5 millions kilometers of underground networks.

2

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

October 2008 – Tragic damage on underground network in Bondy – 1 death, 4 people injured.

In Ghislenghien Belgium, on July 30th 2004 a gas explosion caused 24 death and 132 injured.

Million Euros wasted in human and financial loss

Page 6: The Evolution of Survey Marking and Pegging

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.

N°395 du 11 mars 2011

• Le repère RFID permet de connaître sur le terrain les informations relatives aux réseaux souterrains

• Le marqueur RFID est un clou, un repère mural ou une bornecontenant une puce RFID

33

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

Page 34: The Evolution of Survey Marking and Pegging

• 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 :

N°395 suite

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.

• La fonction matricule, identifie l'objet par un numéro unique. Il devient identifiable et peut être contrôlé

• La fonction traçabilité, définit la nature, le type et les caractéristiques des réseaux

• La fonction géolocalisation, pour indiquer une distance par rapport à un objet. On retrouve sur un même support une mesure relative triangulée, et une mesure absolue géo

rapport à un objet. On retrouve sur un même support une mesure relative triangulée, et une mesure absolue géo référencée

• La fonction consultation donne accès aux informations consignées dans le marqueur

• La fonction maintenance et surveillance des réseaux, pour le suivi des interventions directement sur le terrain
