Une expertise complete de l'etude preliminaire a la supervision des travaux

We analyse geological context, review available data, and propose a targeted investigation program to secure technical choices for project owners.

• Mapping of geological and hydrogeological constraints of the site.
• Tailored reconnaissance program (borings, pressuremeter tests, laboratory analyses).
• Initial recommendations for foundation and earthworks design.

We establish detailed geotechnical assumptions, size solutions, and assess risks to retain a reliable and cost-effective scenario.

• Integrated geotechnical model and preliminary calculation notes.
• Technical and financial comparison of foundation options.
• Geotechnical risk analysis and mitigation roadmap.

We produce final designs, coordinate with design teams, and ensure compliance of geotechnical works.

• Execution drawings, construction details, and technical specifications.
• Validated calculation notes and third-party verification files.
• Technical assistance to contractors during construction.

We supervise earthworks, foundations, and special structures, adjust prescriptions in real time, and issue control reports.

• Site visit reports and compliance sheets.
• Validation of control tests (bearing capacity, compaction, inclinometers).
• Technical opinions on adaptations and encountered contingencies.

We investigate disorders, perform monitoring, and define corrective works or maintenance plans to ensure durability.

• Inspection campaigns, in-situ measurements, and instrumentation.
• Diagnostic report with remediation scenarios.
• Maintenance plan and post-works monitoring.

We deploy mechanised drilling, perform in-situ testing, and collect samples for CALIX laboratory analyses to characterise soils in depth.

• Borehole logs, cores, and pressuremeter, CPT, SPT test results.
• Gradation analyses, Atterberg limits, oedometer and shear tests.
• Geotechnical instrumentation (piezometers, inclinometers, extensometers).

We combine instrumentation, back-analysis, and field expertise to understand pathology origins and guide corrective works.

• Monitoring campaigns and deformation tracking.
• Back-analysis modelling and numerical simulations.
• Remediation dossier with prioritised interventions.

Our engineers monitor site operations, interpret real-time measurements, and advise contractors to adjust methods and phasing.

• Monitoring dashboards with risk indicators.
• Opinions on earthworks and retaining adaptations.
• Weekly reports and end-of-mission summaries.
