Sustainable development

VINCI Construction Grands Projets is committed to protecting the environment at its worksites by:

• protection of natural sites, plant and wildlife at all our worksites, by identifying and limiting significant impacts at the design stage
• active pollution prevention
• improvement to the comfort level of neighbouring populations by limiting nuisances caused by our building activities
• better communication with stakeholders (populations near installations, the public, administrative authorities)
• awareness-raising and training for all company employees to promote our environmental protection approach
• integration of subcontractors to support our environmental protection approach
• dissemination of innovations and best practices to promote continuous improvement in environmental protection

Each worksite builds its own environmental protection plan, defining project objectives and targets

These targets include those of VINCI Construction Grands Projets:
• proper waste management
• proper wastewater management

 

Certification

The environmental management system in effect at VINCI Construction Grands Projets is in compliance with the stipulations of the ISO 14001: 2004 standard and is certified by AFAQ since 2004. It is audited every year as part of VINCI’s environment report.

Water recycling on the Duplex A86 worksite

At the Duplex A86 worksite in France, water used in industrial processes is recycled at a sanitation plant built specifically for the worksite and tunnel-boring operations. Following an initial round of traditional treatment processes, the water is subjected to additional sanitation measures that are exceptional for such a worksite: pH regulation, filtration at a granularity of 50 µm, and effective turbidity control). The quality of recycled water is monitored on a continuous basis by a team of specialists.

CO₂ reduction at the Naga Hammadi worksite in Egypt

At the Naga Hammadi dam, performance tests on alkali-aggregate reaction have allowed the worksite – which needed 390,000 m³ of structural concrete – to use granulates from a neighbouring quarry, therefore reducing lorries use and cutting CO₂ emissions by 10,000 tonnes.
