Engineering, geotechnical surveys and materials

A geotechnical survey is a useful and cost-effective step before starting a construction project. The geotechnician applies his or her knowledge and know-how to ensure the proper realization, optimization and safety of the project to be carried out. Whether for the construction of buildings, bridges, roads, freeways, tunnels, dykes, quays, viaducts, canals, dams, retaining walls, jetties, breakwaters, groins, gabions, riprap, airports, ports, power plants..., the expertise of a geotechnician is essential and beneficial. AGTS provides engineering support throughout your project, from design to completion, to help you better understand the behavior of all types of soil and groundwater.

AGTS offers geotechnical engineering solutions for the management of soil-related risks and those resulting from its interaction with structures. This solution ensures the stability stability of structures and their adaptation to geological and geotechnical contexts.

We list the following tasks:

  • Geotechnical engineering assignments G1 to G5 in accordance with standard NF 94 500 November 2013: G1 preliminary studies, G2 feasibility and design studies, and G3 execution studies of geotechnical works (G3), G4 monitoring and supervision of execution studies and the works
  • Shallow, deep and semi-submerged foundations, retaining walls and screens, slope and embankment stability, soil improvement and reinforcement (rigid inclusions, ballasted columns, drainage), mixed foundations, paving...
  • Complex case studies depending on site conditions (topography, environment, nature and properties, hydraulic regime) and the nature and requirements of the project Hydrogeology (water, sanitation... to be completed: influence of a water table on the execution of works and on the the design of the structure (drainage, casing of a basement), aggressiveness of water with regard to concrete)
  • Natural hazards (landslides, rockslides, swelling soil, soil liquefaction, underground cavities, etc.) underground cavities...)
  • Control and monitoring during design and construction phases
  • Geology
  • Materials: classification, hydraulic properties, mechanical behavior, reuse)
  • Training (in geotechnical software, skills enhancement and case studies)

     A look back at our customer experience

The Abidjan metro in Ivory Coast


In a difficult transport context in the Ivorian economic capital, the Abidjan Metro project is a breath of fresh air for the people of Abidjan.

The project is designed to improve mobility in Abidjan. Initially consisting of 37 km of existing track to be upgraded, the project will continue with the construction of the section from Port-Bouët to Félix-Houphouët-Boigny international airport. This will create the first line of the Abidjan metro from Anyama to Port-Bouët.

AGTS has been commissioned to carry out the geotechnical survey (first in 2015, then in 2023) for this major project, as part of the preliminary design and detailed design studies.

  • What is geotechnical testing?

    Geotechnical testing is the testing of natural materials, such as soil, sand, rubble, rock and groundwater, to determine their physical and mechanical properties. The results of these tests are used to determine the behavior of materials and assess their ability to withstand loads.
  • What is the purpose of geotechnical engineering?

    Geotechnics is a branch of engineering science that focuses on the study of the physical and mechanical properties of soil and foundations. Its aim is to provide information on subsoil conditions and advise on the best way to build structures on the ground.
  • What are the main laboratory tests used to identify soil?

    The main laboratory tests used to identify a soil and its properties include the grading test, the liquefaction limit test, the simple compressive strength test, the water absorption test and the hydrometry test. These tests are used to determine soil composition, structure, density and permeability in order to better understand and evaluate its geotechnical characteristics.
  • What is geotechnical investigation and why is it essential for construction and infrastructure projects?

    Geotechnical investigations provide a better understanding of soil stability and behavior in relation to infrastructure design and construction. The investigations thus relate to soil and groundwater. The aim of this mission is to gain a better understanding of the physical and mechanical characteristics of soils, in order to elucidate geotechnical risks, define the right type of foundations, optimize their sizing and provide recommendations to be followed by the contractor during construction. Your projects of all kinds require geotechnical surveys, which our teams can carry out for you with complete expertise. We operate in a wide range of sectors, including energy, infrastructure and construction, airports, etc.
