UNION PACIFIC RAILROAD – GRAETTINGER & UNION/PLATTSMOUTH

In 2015, a Union Pacific Railroad bridge in Graettinger, Iowa, was failing due to limestone deterioration under 12 piers and needed repair. Using 50-ton hydraulic jacks and shore towers to jack up the steel spans, we removed the limestone piers and replaced them with new, precast sections. All repairs were performed between train traffic.

In 2016, we replaced two separate bridges for UPRR (Union and Plattsmouth). We had a challenging, 30-day requirement and work was completed during a “blitz” in which miles of track were replaced. Due to ongoing train traffic, we were limited to five-hour work windows to install all steel H-piling, and two 20-hour windows to replace the bridges. The project required an extremely intricate schedule as we worked alongside the track replacement gang and multiple track replacement machines.
