The challenge
Meridian State DOT inspects 300 miles of interstate corridor with a team sized for half of it. Every assessment started with a drive: crews logged windshield time to check signs, barriers, culverts, and pavement, and the inspection backlog grew every quarter. Asset records lived in three systems that disagreed about where things were.
The approach
GeoGarmeux flew the corridor with LiDAR and drone photogrammetry, reconciled the three asset inventories into one spatial record, and stood up a corridor digital twin in GeoGarmeux Atlas. Inspectors now open a measurable 3D model at their desk, flag what needs eyes on site, and dispatch crews only where the model raises a question.
The results
- 45% reduction in inspection backlog within the first year
- 300 corridor miles captured and modeled in one field season
- 3 asset inventories consolidated into a single spatial record
“Our inspectors used to spend their week driving. Now they spend it deciding. The twin tells us where to send a truck — and where not to.”
