Worldwide Bridge and Waterfront Facilities

Bridge and Waterfront Facility Inspection

PRIME AE is performing biennial NBIS and UFC bridge safety inspections, including fracture critical inspections, underwater inspections, scour evaluations, structural analysis, and preparation of inspection reports for the Engineering Research and Development Center (ERDC) through the U.S. Army Corps of Engineers for U.S. Army-owned bridges and waterfront facilities that carry vehicular, railroad, and pedestrian traffic, under consecutive five-year worldwide Indefinite Delivery/Indefinite Quantity Contracts.

The bridges, which cross waterways, highways, and railroads, vary in design and include timber structures with timber plank and concrete pan decks, pre-stressed concrete box beams and open girders, reinforced concrete Tee-beams, multi-steel girder and steel beam structures, steel trusses, stone masonry arches, cast-in-place and precast reinforced concrete box, pipe, arch culverts, and corrugated metal culverts. PRIME AE used ladders, waders, man-lifts, and under-bridge inspection vehicles, including rail-mounted cranes, with traffic control as required, to provide hands-on access to all portions of the bridges.

Each assignment included coordination of schedules, including firing range and railroad schedules, scheduling of equipment and traffic control with vendors, and preparation of a pre-inspection letter submitted to the ERDC. Site work at each installation included hands-on, in-depth, inspection, and documentation of approach, deck, superstructure, substructure, and channel elements. Additional services provided by PRIME AE include rehabilitation, full design, and the demolition and replacement of bridges. Since 2011, PRIME AE has completed project assignments covering more than 2,500 bridges under the two contracts.
