Personnel safety above all

Safety performance is the precondition of all other aspects of performance, and it is thefirst proof of the quality of service we offer to our clients.

The internal Victor prize, created in 2001, is awarded each year for the best safety performance recorded among the various elements of our Group. The motivating effect of this internal competition has resulted in significant progress in our overall safety performance.

Significant business units have already succeeded in attaining our "Zero Accident" target, showing everyone that this is an attainable objective for all.

Our success in this area is confirmed by several major external professional awards:> First Prize for Safety from Entreprises Générales de France - BTP.> First Prize for the "Best Safety PerformanceSubcontractor Award - Civil and Foundations Section" in Hong Kong.> Safety award presented by the Fédération Nationale des Travaux Publics.> “Tulsa District Eagle Eye Construction SafetyAward”, USA.

Urban diaphragm wallThe diaphragm wall process is a global solution to problems encountered by clients in city centres: small building site areas, sites with noise restrictions, traffic restrictions, protection of nearby buildings, use of environmentally - friendly products.

On-board electronics

Enpafraise (Hydrofraise drilling parameters recording)

Soletanche Bachy's commitment to new excavation processes has led to tremendous progress. It enables:· correction of deviation of the excavation, · accumulation of recorded information to optimise efficiency and assist automatic machine control,· real-time, automatic print-outs of full reports on all operational data (verticality, excavation rate, depth, soil profile, obstructions, etc.).

Grouting

Grouting is a range of processes for soiltreatment that uses slurries to improvethe soil resistance or the soil permeability.

Soletanche Bachy applies major innovationsto the standard grouting processes, mainly in the following two areas:

· The non-contaminating, long lastingand highly penetrable grout, · Electronics and computer technologyapplied at every stage, thus offeringtechnical precision and transparency.

Our processes guarantee the quality of your works

Our processes guarantee the quality of your worksMonitoring and control

A s p e c i f i c control system developed by Soletanche Bachy allows real-time and precise monitoring of pressure, volumes and rates of the grouting, in order to place the grout exactly where it is required.

When underground works are located nearby existing buildings and structures, compensation grouting must be used to guarantee optimal safety .

The grouting control system has been extended for this purpose by Soletanche Bachy to integrate in a closed loop the real-time monitoring of soil movements offered by Geoscope system (Soldata) the automatic control of grouting plants together with the anticipation of settlements.
