For almost 20 years now, Domson has been providing bridge NDT services to structural steel bridges, relating to initial fabrication and erection (visual QA inspector) as well as in-service fatigue inspections. Our inspections are carried out by technicians certified to CGSB standard 48-9712 as well as CSA W178.2. All inspections are directed by a professional engineer experienced in bridge inspection and certified as a CSA W178.2 level 3 inspector.

Not only can you rely on our field personnel for your inspection needs, but our in-house engineers also develop inspection test plans and create professional bridge inspection reports complete with CAD drawings of bridge details.

We use a combination of visual inspection and various nondestructive testing methods to inspect the following structural components:

  • Bridge/box girders
  • Abutment welds
  • Trusses and columns
  • Bolts and rivets
  • Stiffener plates
  • Diaphragms
  • Splices
  • Bearing plates

If you need inspection done on complicated bridge structures (i.e. truss structures) that can’t easily be reached by a bridge master, then our rope access inspection team may be able to assist.

Steel Bridge Inspection & Fatigue Inspections

As Ontario’s bridges get older, there’s more and more demand for in-service fatigue inspections.

Magnetic Particle Inspection Services

Magnetic particle inspection is often performed on critical suspect areas.
