Project studies - Design

In-depth analysis and tailor-made plans for ecological restoration
The company’s many years of experience in carrying out environmental work have allowed it to become specialized in the design and the implementation of erosion management projects. Two aspects are particularly addressed in the studies we conduct: the rehabilitation of gullies, quarries or waste spills and the revegetation of degraded areas, not only on mines but also in other ecosystems such as sclerophyll forests, mangroves and more.
These projects are primarily overseen by three key persons within the company, led by the manager Marc-Henry DELRIEU, who has more than 20 years of experience in the New Caledonian revegetation field:
- Danielle SAINTPIERRE, PhD in Agroresource Sciences: 18 years of experience in the field of revegetation,
- Adeline RECK, Environmental Engineer: 10 years of experience in the field of revegetation,
- Leslie MAÏ VAN’Y, Ecological Engineer: 2 years of experience in the field of revegetation.
This deliberate choice to position highly qualified staff at the head of our projects was evident in providing clients with the best possible service. This comprehensive management of operations (from cost estimation to invoicing, including supervision of execution) ensures a good understanding of the client’s expectations and their transposition into fieldwork.
Detailed process for rehabilitation and revegetation
To best meet our clients’ needs, each project is carefully examined on a case-by-case basis.
Thus, gully or waste spill rehabilitation projects are carried out as follows:
- Submission of the issue by the client
- Preliminary site visit with the client
- Analysis of the visit and reflection on potential solutions
- Confirmation visit and measurements
- Cost estimation of selected solutions (ranging from low-cost solutions to heavier works and based on ecological engineering); technical note drafting and associated mapping
- Discussion of the proposal with the client
- Proposal modification, if necessary, and validation
- Execution of the works, supervised by the project manager involved in the project from the start
Similarly, revegetation projects are designed from A to Z, according to the following diagnosis steps:
- Site visit with the clients enabling an understanding of their needs. This allows:
- The engineer to assess the substrate’s characteristics and observe the quality of the surrounding vegetation (specific richness, dynamism),
- To determine the logistical constraints induced by the site,
- To initiate a preliminary discussion on feasibility, possible techniques, and the areas concerned.
- Analysis the information collected during the visit and figure out the most suitable technique for each zone or parcel (i.e. planting, hydraulic seeding, dry seeding, aerial seeding, etc.), as well as the list of species to reintroduce together with the inputs to apply (in the case of seeding).
- Technical proposal drafting and estimation, to provide the client with a clear and comprehensive offer.
- Proposal discussion, with the client and modification, as needed.
- Upon proposal validation, planning of the intervention.
- Works implementation, supervised by the engineer involved in the project from the start.
Instructions from the project managers are relayed on-site by specialized and committed team leaders, who are all long-serving employees. Our teams are trained and qualified in the various techniques we offer and in their implementation, in accordance with professional standards.


Social and environmental commitment in New Caledonia
Our involvement in many environmental restoration operations, over more than 30 years throughout New Caledonia, has helped foster connections with local populations. Aware of the necessity to safeguard the interests of these communities, integration of people living in villages or tribes near our work sites is automatically considered, as early as the project design step. With a similar mind-set, part of our endemic/native seed collection is outsourced to associations based in local tribes.
This approach combines social equity (through training and compensation for people who often have limited access to employment) with economic efficiency, as the company’s expenses (travel, accommodation, etc.) are indeed optimized.
