Bridge inspections services are authorized and regulated by the Federal Highway Administration
(FHWA).Bridge inspection services are in accordance with the National Bridge Inspection Standards
(NBIS) and the qualified team leaders are thoroughly familiar with the latest Federal Highway
Administration(FHWA) bridge inspection procedures and principles. The checkup personnel are skilled
and qualified in work zone safety, railway safety measures, and restricted space entry, as well as in the
use of fall protection tackle. Furthermore, The staffs should be up-to-date with OSHA safety
requirements. Requirements are further regulated on a state by state basis and in many states by the
district project managers.
These are the six (6) different types of bridge inspections, each with arranged inspection interval
1.Preliminary or Catalog Assessments – These are done no more than 90 days after a new bridge is put
in service for the first time.
2.Repetitive or bi annual Inspections – These are done at 24 month intermissions.
3. Damage Checkups – These are done after an accident or a ordinary incident (hurricanes, earthquakes
and weather factor etc). Sometimes referred to as forensic inspection.
4. Underwater Checkups – These are done at sixty (60) month intermissions.
5. Detailed & Distinct Checkups – These may follow the 60 month intermission for checkups of bridges
that require specialized apparatus (for instance cable stayed or suspension bridges) or may be
conducted supplement to a routine, damage or preliminary checkup.
6. Interim Checkups – These are programmed at the preference of the person in charge of an agency’s
bridge inspection activities.
Bridge inspections are characteristically conducted on a span by span basis, for multi-span bridges – a
span is the parallel space between two bridge supports. It’s like inspecting a diminutive bridge within a
bridge. This allows examiners to gather and report on their discoveries resource fully on the bridge
elements from one span to the next. The inspections process is similar for underwater bridge inspection,
but varies on how the discoveries are collected – the designated diver examining elements and
taking measurements whilst underwater and reporting findings to the onshore inspector.
For both inspections types, a dangerous finding on a bridge element can trigger some supplemental in-
depth inspection of the bridge, load rating recalculation, place the bridge on a scour perilous list for
monitoring or in severe cases closure of the bridge. These judgments are made on sight by the lead
inspector in charge of the bridge, but are later revised by a regional supervisor upon submission of the
inspection report. The assessor eventually approves or rejects the findings in the inspection report.

2. Today’s infrastructure projects require unified solutions to meet the demands of multi-discipline project
teams actively engaged in planning, design and construction.
On a final note as time takes its toll on each and every country’s aging bridges, the scrutiny that is
necessary to provide for their longevity becomes all the more important issue on ground. Demand for
well-educated, motivated bridge engineering specialists who specialize in both inspection and custom
bridge design has never been higher. Today’s bridge engineer must simultaneously employ the most
important and the most sophisticated design techniques while simplifying the most complicated bridge
configurations and construction sequences.
Infrastructure Preservation Corporation, IPC is a nondestructive testing and robotic engineering
company that specializes in bridge inspections and other infrastructure assessments. IPC’s mission is to
change the department of transportation’s current manual and visual inspections to adopt more
modern technology and robotics. These devices provide more quantitative data with fewer lane closures
and are safer to conduct for the inspectors and the traveling public. The information they provide allows
the department of transportation to better allocate their budgets and resources and does it at a lower
cost. IPC’s services allow for not only urgent repairs to be made but for preventative maintenance by
locating problem areas earlier in their lifecycle, saving billions in untimely replacements. You can learn
