Ginger BURGEAP

Nexity Ville et Territoires is developing the “Alsthom site” under a participation agreement signed with SEQUANO Aménagement; this site is part of the Saint-Ouen Docks mixed development zone. Since 2006, Ginger BURGEAP has been managing the restoration work required to transform this former industrial site into a new mixed commercial/office/residential district. Ginger BURGEAP carried out the studies prior to the commencement of the works (soil characterisation) and then ensured the supervision and acceptance of the works, which were carried out block by block.

As a partner of Biotope, which was commissioned by Société du Grand Paris to carry out the strategic environmental assessment, BURGEAP carried out the sections on water, soil, subsoil, natural and technological risks, subsoil occupation (vibrations, networks and tunnels, foundations) and urban planning. These findings were then used by Société du Grand Paris in the project planning process to optimise the impact of the project in a very densely populated urban area. 
In a second phase, Ginger BURGEAP was also responsible for the following aspects of the impact study: topography, pedology, geology, hydrogeology, surface water, natural hazards, subsoil occupation, technological risks, contaminated sites and soils, and urban planning.

For more than 30 years, Ginger BURGEAP has provided the Communauté Urbaine de Lyon (Urban Community of Lyon) with full and regular technical support for the design, construction and operation of the Crépieux-Charmy water catchment area, one of the largest in Europe. This support includes advice on the use and development of real-time management software and expertise in hydrogeological monitoring. Ginger BURGEAP also works with Greater Lyon to help manage the water catchments that supply drinking water to the surrounding area and to develop a strategic approach for the area as a whole.

For each development plot, a diagnosis (DIAG), a management plan with predictive residual risk analysis (PG/ARR) and project management for the management of areas of concentrated contamination and non-inert excavated material from the various projects are carried out. One of the unique features of this site is the creation of an on-site platform for the management of contaminated soil from the various plots. More specific missions have been carried out, such as interpreting the state of the environment to check the health compatibility of building uses around a highly contaminated plot.

As part of the Joia project on the Meridia mixed development zone in Nice, Ginger BURGEAP is regularly called upon to support property developers in the following areas:

• The design and dimensioning of rainwater management systems;
• Flood risk management (assessments and design proposals);
• Regulatory support, including the preparation of regulatory dossiers;
• Estimating drainage flows during the construction phase, and technical feasibility studies for the creation of an additional basement level.

During the construction of a cinema on the site of an old gasworks, the town of Annonay discovered that the site was contaminated with hydrocarbons. In response to this finding, the town of Annonay commissioned Ginger BURGEAP to carry out the following studies: diagnosis, management plan and residual risk analysis. It then entrusted Ginger BURGEAP with the project management for the design and supervision of the works.

Following the discovery of 3 discarded electrical transformers in the bed of the Durance river, the DDT (land use directorate) of department 84 requested the characterisation of the contaminated sediments and the management of this concentrated source of pollution. Ginger BURGEAP carried out the studies (sediment characterisation, management plan, etc.) and then managed the project from consultation with the contractors to acceptance of the works.

As part of the project to remove waterproofing from school grounds, the town of Miramas commissioned Ginger BURGEAP to carry out the following services:

• Soil contamination studies to ensure that the project is compatible with the environmental status of the site in terms of health and the environment;
• An agronomic study to evaluate the possibility of reusing the existing soils;
• A hydraulic study to define the characteristics of the existing soils in order to assess their capacity to infiltrate rainwater;
• Proposals for removing all or part of the waterproofing for each school.

As part of its commitment to sustainable development, GRAND DELTA HABITAT commissioned Ginger BURGEAP to support the "EcoQuartier" certification process for the "Les Oliviers" neighbourhood in Morières-lès-Avignon. Ginger BURGEAP worked in partnership with the architect Jérome Siame to design the project, carry out an environmental assessment of the site and carry out hydraulic studies for rainwater management (in accordance with water regulations).
 

As part of its expansion, and in compliance with water regulations, the Nîmes University Hospital called upon Ginger BURGEAP to draw up an environmental permit application. This required the completion of a global hydraulic study to improve rainwater retention across the entire site managed by the Nîmes University Hospital, the completion of an environmental impact study, as well as a project management assistance mission.

The Métropole Nice Côte D'Azur is the contracting authority for the connection of the Voie Mathis to the Route de Grenoble and then to the A8 motorway via an underground route. It has commissioned Ginger BURGEAP to carry out the following studies:

• An environmental assessment of an area where the presence of a former service station had been identified and where hydrocarbon odours had been detected;
• An opinion on the risks associated with the management of the excavated material;
• The characterisation of the excavated soil generated by the construction of the underground route and an orientation plan for the excavated soil.

On a site polluted with chlorinated solvents and migrating into the groundwater, the following actions were agreed with the authorities (DREAL):

• The treatment of the two source areas with high concentrations of VOCs to improve the environmental quality of the soil and reduce the impact on groundwater
• Continuous environmental monitoring of the site
