Still Hanging from Ropes for Your Bridge Inspections?
U.S. DOTs are using digital twins for remote bridge inspections, ensuring the safety of their workers and improved visibility.3D / VDC Infrastructures
One example is the Minnesota Department of Transportation (DOT). The state currently has 20,000 bridges, all of which need to be inspected regularly so that the state can properly maintain them over their lifetime and find out what they need to do to replace them. Jennifer Wells, state bridge inspection engineer at the Minnesota DOT, explained that, “Most of those engineers don’t go out in the field much so it’s hard to relay through close-up pictures and trying to explain to them what I’m seeing.” There was a great opportunity for the Minnesota DOT to use drones and Bentley software to complement and augment standard and in-field inspections. They could review the data from these inspections quickly and easily from anywhere. When engineers look at time-lapse comparisons of detailed changes, they can annotate specific areas of concern and designate anything that needs to be specifically reviewed in the field. Field crews can see all the inspector notes right on the structure, which is more visual, accurate, and efficient. All these capabilities are geared toward saving costs, avoiding risks, and reducing the time required for inspections.
