Independent Field Inspection

Baker Testing provides quality bridge inspection services around the world for both new construction and in-service bridges.

In-Service Bridges

Helping highway agencies identify deterioration and plan for repair, Baker Testing offers close inspection of components using a variety of non-destructive testing (NDT) methods. Our technicians test and report on a variety of bridge components, looking for fatigue cracking, defective components, and corrosion.

  1. Bridge Pins
  2. Girders
  3. Beams
  4. Stringers
  5. Bolts
  6. Rivets
  7. Welds

Preliminary inspection results are available on the job, allowing inspectors and on-site managers to collaborate.

Specialized Bridge Access

In compliance with the safety regulations of the Occupational Safety and Health Administration (OSHA), Baker Testing inspectors are familiar with specialized access techniques. Proper inspection of bridges may require access from a bucket truck staged on platform beneath the bridge or snooper truck where the inspector is lowered over the edge of the bridge deck by a mechanical boom.

Inspection of New Bridge Construction

Structural Steel and Weld Inspection is provided for new bridge construction, in compliance with the Federal Highway Administration requirements.

NDT Testing Techniques

  • Phased Array - produce simultaneous multiple-beam ultrasound to determine quality and integrity of welds
  • Magnetic Particle - identify surface flaws and seams
  • Radiography - locate embedded flaws on film or digital x-ray
  • Ground Penetrating Radar - identify the location and depth of objects hidden to the eye such as structural steel embedded in concrete
  • Visual Inspection - perform independently or in conjunction with all other inspection methods

Welder Qualification

Both individual and large volume/new project welder qualifications are available. Read more: Welding Qualification
