Coastal Engineering’s ADCI-certified commercial divers were contracted by East Penn to perform an underwater inspection of this stone masonry railroad bridge. During the inspection we determined that emergency repairs were required due to the undermined and partially collapsed footings. Our team assisted with the reparation of a repair plan and subsequently provided underwater and marine services to perform the recommended repairs.

 

Work began with the mobilization and assembly of a float stage. Initial work included the hanging of a safety net along the fascia and cleaning of the repair areas via high-pressure water jetting. We then repointed 150 LF of the south abutment footing with Sika VOH and installed cement forms along the undermined areas beneath both abutment footings. Approximately 30 CY of concrete was pumped into the undermined aera.
