Precast/prestressed concrete girder damage and subsequent repairs on BNSF Railroad Bridge Nos. 105.67, 106.6, 107.65, and 108.84 on the Abbott to St. Michael Line in Cairo, NE were investigated.  Girder production and bridge erection was investigated to determine the cause of the damage to the girders.  The structural integrity of the repaired girders was certified. 

10th Street Viaduct Replacement Project, Omaha, NE
As part of this bridge replacement project, adjacent buildings required temporary shoring and the tracks on the railroad corridor below required protection from falling debris.  InfraStructure designed the necessary temporary shoring as well as reviewed the bridge removal plan.  A special investigation of the adequacy of the proposed track protection plan was required and involved field observation and documentation of the proposed protection system.
