Role Of Bridge Inspection In Bridge Maintenance

Bridges and roads are valuable assets of any nation and therefore they must be maintained in good condition. The maintenance of bridges highly depends on effective monitoring and inspection techniques. The technology used in these processes must be able to identify the problems occurring both on the surface and inside the structures but unfortunately, methods used in conventional bridge inspection and monitoring are not very effective.

During traditional routine bridge inspections inspectors conduct manual subjective inspections that although they comply with federal and state regulations do not do enough to maintain the safety of our nations infrastructure. Both AASHTO and the FHWA need to do more to ensure that modern technology and robotics are integrated into the required inspection parameters.

The current manual methods have several limitations e.g. visual aids have limited field of view which can provide limited data. Moreover, the bridge needs to be closed during bridge inspection and the crew need to put themselves in dangerous situation during inspection.

Infrastructure Preservation corporation (IPC) has revolutionize the bridge inspection and monitoring process with its automated tools. Our patented technologies utilize non destructive methods like electromagnetic waves, ultrasonics, infrared waves, aerial imaging, laser scanning etc. to find out any kind of deterioration or corrosions occurring externally and internally in a bridge and its components.

Our advanced technologies like CableScan® and PoleScan® reduces the risk associated with suspension cable inspection and pole inspection and also improvise data collection by providing the 360 degree field of view of the cables and poles of the bridge. The difference of results can be easily imagined by looking at the methods used in traditional manual bridge inspection and our robotic technology.

For example, if we take a case of pole or cable inspections then which do you think would collect more data? A bridge inspector hoisted hundred feet above the ground and checking the poles or cables for any corrosion and damage from only one side with the help of a helmet flashlight OR a robot inspecting the structure thoroughly from all sides. It is very clear that the robot will be able to collect more and accurate data than its human counterpart. The robotic data provides quantitative data that can help the asset owners allocate the proper resources to maintain our infrastructure assets.

Similarly, our CrackScan® technology collects accurate data from the deck and under the bridge of a concrete or steel structure. It is able to find those cracks which are not visible to naked eyes and therefore not considered in the final condition assessment report. The 2D and 3D maps created with this technology depicts the length, width and position of the cracks so that these cracks can be monitored and repaired accordingly. Moreover, during inspection with CrackScan®, the bridge doesn’t require any closure of the lanes during a bridge inspection which is important in that closing lanes delays traffic and parking heavy equipment on a bridge causes accidents. Robotics need to be adopted so that  our nations bridges can be properly maintained, traffic can keep moving and products can get to market and help ensure the publics safety.

IPC’s products are non-invasive but they accurately locate the problems like voids, cracks, water intrusion, delamination and deboning in concrete and steel structures. Therefore in order to reduce the time, total cost and increase public safety and and inspection crews modern technology and robotic bridge inspections are the best way to provide accurate condition assessment reports.
