The Charles De Gaulle Express project is part of Le Grand Paris Express which revolves around a public transportation network plan consisting of four metro lines around Paris, along with the expansion of two existing lines. The goal of this railroad project in the Ile-de-France region is to connect the Paris-Est train station to the Paris-Charles-de-Gaulle airport in less than 20 minutes. With a budget of more than 1.7 billion euros, the CDG Express is a major project that will shape Parisian mobility shortly.
Once again, Cementys has been recognized for our reliability, responsiveness and technological solutions by providing a high-precision automatic topographical monitoring for one of the largest Parisian railway projects dating back to the beginning of the century while accompanying Eiffage and SNCF Réseau on one of the first works of the CDG express in Tremblay, Seine-Saint-Denis.
Cementys monitors, in real-time, the impact of work on the RER line B. We do this through our 6 fully automated theodolites, 500 prisms located on the rails and our innovative data processing software.
Over 3 months, Cementys will accompany SCNF Réseau on monitoring the impact of the sewage clean-up operation on the RER B North line.
