Bridge Inspection

JMT provides bridge inspections and other types of structural inspections for federal, state, county, agency, and privately-owned bridges and structures, consistent with National Bridge Inspection Standards (NBIS). These range from routine, biennial inventory inspections to in-depth, emergency inspections, including underwater inspections.

All inspection work is performed under the direction of registered professional engineers.  JMT team leaders have completed the NHI Safety Inspection of In-Service Bridges course as well as other specialty training, and have conducted the following types of inspections:

  • Routine biennial
  • Fracture critical member inspection
  • Confined space inspection
  • Interim inspection
  • Emergency inspection
  • Scour inspection & evaluation
  • Underwater inspection
  • InspectTech

We use the latest technology and equipment to improve the efficiency, quality, and cost-effectiveness of our field crews and office tasks. Specialized access equipment and rigging allow access to areas of bridges that normally require traffic lane closures, thereby minimizing disruption to the traveling public.

JMT has performed bridge inspection services for on-call and scoped projects from Virginia to New York.  We can mobilize an inspection team within a few hours for an emergency response.

  • Simple & continuous steel I-beams, box beams, trusses & girders, including curved girders
