Detailed inspections

Damage survey

  • Visual diagnosis
  • Periodic Detailed Inspection ("IPD") according to ITSEOA (technical guide to the surveillance and maintenance of civil engineering structures)
  • Remote inspection by ultra-high definition photography
  • Inspection by drone equipped with an HD camera of very large structures (dams, viaducts, water towers, etc.)

Diagnosis

Drawn up after the detailed inspection, the diagnosis is an in-depth survey of the structure.

It contains information on:

  • damage observed,
  • constructional features,
  • geometry of the structure,
  • state of the steel reinforcements,
  • materials constituting the structure…

Reconnaissance, investigations and analyses

Reconnaissance surveys and investigation campaigns

  • Non-destructive auscultation of structures: detection of steel reinforcements using a Ferroscan© pachometer up to 10 cm and radar up to 50 cm depth
  • Destructive drilling with a pneumatic drill
  • Taking of samples: core sampling, disk cutter, very deep drilling
  • Qualification of materials: measurements of the corrosion potential or reinforcements, measurement of carbonation depth, surface hardness with a sclerometer, measurement of adherence of a coating using a force gauge, ultrasound measurements in concrete, video endoscope inspection, etc.
  • Monitoring instrumentation: light or continuous instrumentation


Laboratory analyses and tests

  • Mechanical tests on concrete: compressive and tensile strength of concrete
  • Physical/chemical analyses: measurements of density/porosity, measurement of carbonation depth on concrete, chloride content, etc.

Engineering

  • Photographic reporting
  • Marking of damage on plans, structural plans
  • Ranking of damage
  • Opinion on the structure's state of conservation
  • Calculation of bearing capacity
  • Recommendation of repair work
