I-72 at I-55 Mobile LiDAR Scan

Illinois Department of Transportation

Horner & Shifrin provided a Mobile LiDAR to scan the existing 17 miles of pavement to create existing surface design model used for a mill and overlay design.


Using our mobile LiDAR vehicle Horner & Shifrin scanned approximately 17 miles of State-controlled four-lane divided highway including flyover ramps, cloverleaf intersections, bridge clearances and exit and entrance ramps. The LiDAR data was collected without causing any traffic disruptions, lane closures, or requiring any field personnel to work near live traffic. Once the data was reduced H&S provided a 3D Microstation drawing meeting IDOT specifications with bridge clearances and surface DTM showing the existing pavement cross slopes, superelevations, and guardrail heights. The field data was collected 98% faster and 100% safer than conventional methods, and the final product was delivered less than 30 days from the notice to proceed, ultimately allowing IDOT to keep a major improvement project on schedule and under budget.
