Challenge
Bridge inspections are traditionally performed with a 'paper and pencil' process that can be lengthy (3-4 weeks per bridge), costly, and at times, risky.
Skydio Solution
With the help of Collins Engineering, Minnesota Department of Transportation (MDOT), implemented a more advanced solution for bridge inspections. Skydio drones were used to collect detailed data with 3D scanning and then create digital twins of the bridge to use for pre-inspection work for crews to reference while in the field. MDOT estimates 70-80% of defects are detected on the digital twins before field inspections are conducted.
Results
MDOT experienced a 30% reduction in inspection costs and reduced time in the field by 50%.
“The typical process for a bridge inspection is using pencil and paper, and it would take three to four weeks in the field. We cut that time to about two weeks, two and a half weeks, shaving off a week of time in the field. We’re estimating it's about a 30% reduction in inspection costs. And at the same time, we're delivering better information.
