Grand Surveying in Grand Paris

Advanced solutions for tunneling and monitoring keep the largest transportation expansion project in Europe on track
Advanced solutions for tunneling and monitoring keep the largest transportation expansion project in Europe on track

Paris is grand — and getting much grander. One of the most visited — and loved — cities in the world, the City of Light began the Grand Paris initiative in 2007 with the goal of keeping Paris competitive with the world’s greatest cities into the 21st century.

Tunneling is particularly susceptible to schedule and budget-busting hazards — a problem in one area can shut down work over an entire line. Eiff age GC and Razel-Bec turned to their hardware and software providers to seek out new solutions to reduce risk and speed construction. The decision to involve their technology suppliers is paying dividends. Two of Eiffage GC and Razel-Bec’s Grand Paris joint ventures implemented several advanced surveying applications for tunneling, including automated real-time monitoring.
