     A look back at our customer experience

The Youth Olympic Games in Dakar, Senegal


The preparations for the Youth Olympic Games are in full swing. AGTS is not to be outdone. As part of the work undertaken to improve and upgrade sports facilities, AGTS had the advantage of carrying out geotechnical and hydrogeological studies over a period of 3 months. This large-scale project will enhance Senegal's sports facilities for the high-level Olympic Games.

geotechnical engineering on materials
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.
Tensile testing machine
Material tests

Whether destructive or not, materials testing provides an exhaustive picture of the description of material properties. These tests are therefore a perfect tool for gaining a better understanding of materials, and in turn data that facilitates decision-making on a given project. 

Rely on AGTS to manage the risks associated with materials testing and ensure responsible operations that comply with current regulations.
