Structures and materials test laboratory

Structures and materials test laboratory

The structures and materials test laboratory (LEMS) is a unit of the inPACT Institute of the Haute école du paysage, d’ingénierie et d’architecture de Genève (HEPIA).

The LEMS has skills in applied research and development (aR&D) in the areas of construction materials:

  • Tests on materials
  • Analysis of structures
  • Tests on structural elements
  • Control and tests in situ

The LEMS participates in teaching knowledge of materials used in construction. The laboratory equipment enables the students to perform the tests defined by the standards in force relative to these materials. The design, implementation of testing of full-scale structures completes the teaching of the mechanics of structures made of steel, wood and concrete.

The LEMS performs tests on behalf of design consultancies or construction companies, notably tests on the resistance of concrete to compression or on the resistance to tension of concrete reinforcements. Tests on structural elements are also carried out in the areas of steel, aluminium, wood, concrete and composites as well as expert appraisals of existing structures.

The resources, experience and relational networks of LEMS enable the multidisciplinary handling of projects and aR&D mandates that are assigned to it, seeking and privileging dialogue with the client. To this end, and in partnership with the client, the project is broken down into its theoretical, numerical and experimental components, to provide a complete analysis of projects that are handled.

The objectives of the laboratory are to guarantee, for its analyses:

  • The reliability of the results and traceability of all actions and information relating to them.
  • The deadlines agreed with clients to respond to specific urgent matters.
