Geotechnical Missions

Mission G1 - Preliminary Geotechnical Studies

Mission G1 ES - Site Study

Conducted before a preliminary study or a preliminary draft study, this phase aims to establish the initial geological model of the site. It also provides recommendations for the installation of an as-yet undetermined structure and allows for the initial identification of geological risks through documentary research.

Mission G1 PGC - General Principles of Construction

Conducted during a preliminary study or a study of a preliminary draft, this phase aims to establish the conceivable general principles of construction for the project. It is based on defining, implementing, and/or monitoring a program of geotechnical investigations.

Mission G2 -Geotechnical Design Study

Mission G2 AVP - Preliminary Project

Conducted during the preliminary project phase, this step analyzes the constructive principles and adaptation of the project to the soil. It also provides the dimensional draft of a typical profile for each geotechnical structure. This approach is based on defining, implementing, and/or monitoring a program of geotechnical investigations, allowing for an initial estimation of the quantities involved.

Mission G2 PRO - Project Phase

Conducted during the project phase, this step provides an updated synthesis of the site. It includes the execution methods for geotechnical structures, associated threshold values, as well as calculations for optimal sizing of all geotechnical structures and for all construction phases. This step allows for a preliminary estimation of quantities, timelines, and execution costs for these structures. If needed, additional investigations are carried out.

Mission G2 DCE / ACT

Conducted during the phase of consulting with companies, this step plays a dual role. On one hand, it contributes to the development of the Business Consultation File for geotechnical structures, and on the other hand, it provides assistance in establishing Work Contracts. This involves drafting the technical documents necessary for consulting with companies. Additionally, it assists the project owner or project management in the process of selecting companies and conducts the analysis of technical offers.

Mission G3 - Geotechnical Execution Study and Monitoring

This stage aims to reduce residual geotechnical risks by implementing timely corrective measures for adaptation or optimization.

In the study phase, this mission involves a detailed study of geotechnical structures, including assumptions, definition, and sizing, as well as methods and conditions of execution. Additional investigations may be undertaken if necessary.

During the monitoring phase, the approach is to monitor the execution of geotechnical structures, verify the data, and contribute to the establishment of the end-of-work file, as well as recommendations for the maintenance of geotechnical structures.

Mission G4 - Geotechnical Execution Supervision

This stage aims to ensure compliance with the project objectives, as well as the geotechnical study and execution monitoring.

During the supervision phase of the execution study, it involves providing opinions on this geotechnical study, potential adaptations of geotechnical structures proposed by the company, as well as the monitoring program and associated threshold values.

In the supervision phase of execution monitoring, this approach is manifested through opinions formulated after specific interventions on the construction site. These opinions concern the geotechnical context, the observed behavior of the structure and its surroundings, as well as the adaptation or optimization of the geotechnical structure.

Mission G5 - Geotechnical Diagnosis

Throughout the development of a project or the lifespan of a structure, this mission involves, as part of a specific intervention, the study of one or more geotechnical elements for a specific diagnosis, without involvement in other geotechnical aspects.

This mission may include, after documentary research, the determination of a specific investigation program and its implementation.
