Inspection and investigation

James Fisher Strainstall (JF Strainstall) has a number of specialist solutions for structures and investigation methods.

We specialise in the implementation of special inspections for highway and rail bridges including:

  • Special visual inspections
  • Measurement of as-built details
  • Detailed investigation of current conditions
  • Use of traditional non-destructive testing techniques (MPI, eddy current, ultrasonics, radiography)
  • Advanced ultrasonics (phased array ultrasonics, long-range, automated and robotic investigation, total focusing method)
  • Use of unmanned aerial vehicles (UAVs) for visual and ultrasonic investigations
  • Short-duration monitoring and load tests

We can provide asset owners with extensive condition investigations and guidance by using several infrastructure asset management services, together with extensive experience from a team that includes chartered civil engineers. Our services range from desk studies to complex data analytics and can include many varieties of inspection and testing. We are bringing together the breadth of technologies and experience within the James Fisher group to provide comprehensive asset condition information and interpretation.

Our capabilities

  • Advise on asset management risks and prioritisation
  • Offer an overview of techniques available
  • Guide appropriate measures for specific scenarios
  • Conduct combined investigations to give complete condition information
