Bob Kerrey Pedestrian Bridge Underwater Inspection
As a subconsultant to HNTB Companies, GBA performed an underwater inspection of all submerged substructure units on the Bob Kerrey Pedestrian Bridge over the Missouri River in Omaha, Nebraska.
- Level I and Level II underwater inspections were performed with a minimum of 10% Level II inspection.
- Acoustic imaging was performed on all submerged substructure units where the water depth was greater than 10 ft.
- A bathymetric channel scan was performed from approximately 300 feet upstream to 300 feet downstream with channel soundings along profiles at 100 feet upstream, centerline, and 100 feet downstream of the bridge.
The final report included repair recommendations, substructure condition ratings and notes, channel sounding plan and profile, bathymetric channel scan plan view and inspection photos.
