BRIDGES & TUNNELS

REPAIR OF EIGHT IMPACT DAMAGED BRIDGES

The eight bridges off of I-87 serve thousands of cars every day. The bridges connect I-87 to various counties throughout New York State and are maintained by the New York State Thruway Authority (NYSTA). Work on these bridges includes repair of structural steel members affected by corrosion loss, impact, fatigue cracks, etc. Targeted members include stringers, girders, floor beams, columns, bents, steel pier caps, diaphragms, cross frames, etc. All work is performed in accordance with the New York State Steel Construction Manual (NYSSCM).

JPCL has been retained to provide structural steel welding inspection and nondestructive testing services including Ultrasonic and Mag-particle testing. JPCL provided NYDOT certified NDT inspectors to perform this task.JPCL has been retained to provide structural steel welding inspection and nondestructive testing services including Ultrasonic and Mag-particle testing.

BIENNIAL INSPECTION OF BAYONNE BRIDGE

The Bayonne Bridge connects Staten Island, New York with Bayonne, New Jersey. It is a Steel arch bridge, the total length is 5780’ and the longest span is 1675’. The total height above Kill Van Kull is 215’ which was opened almost at the same time before the end of inspection cycle. There are 4 lanes and it is maintained by Port Authority of New York and New Jersey (PANYNJ). Bayonne Bridge is one of the longest steel arch bridges in the world with a 1675-feet central span.

JPCL Engineering was hired to perform the Biennial Inspection of the Bayonne Bridge for the year of 2017 as an Assistant Team Leader. The work included preparing reports for Biennial Inspection and Condition survey report as per NYSDOT, NJDOT & PANYNJ standards. Hands-on inspections and assessments were conducted, including sounding of concrete to identify voids and potential problems. This project involved bridge rating in accordance with PANYNJ standards.

The findings including Immediate actions, priority repairs, safety repairs, routine conditions and findings with no recommendations were reported with on-site photos and AutoCAD drawings as per PANYNJ standards were submitted.

BIENNIAL INSPECTION OF GEORGE WASHINGTON BRIDGE

JPCL Engineering was hired to perform the Biennial Inspection of the George Washington Bridge for the year 2017 as an Assistant Team Leader. Prior to the inspection the load rating analysis (a critical component) was done to declare the bridge fit for Inspection and to verify if the bridge is capable to withstand all the Dead Load, and Live Load.

The work includes inspection of a Bridge and its entry/exit connections from Foundation to the Deck, lower level’s Floor beam, Stringers, Stiffeners, underside of decks, and various other components. The previous biennial inspection reports were reviewed for changes occurred during the two year period. The Anchorage of the Bridge was inspected by going inside the New Jersey & New York Towers towards the foundation of the bridge and inspecting every stringer and its pedestals with a visual and physical inspection. The Signs Structures on the bridge were visually inspected with a closer look on its current condition and the supports provided for it. The Light Poles, sidewalk and Rail Posts on the Upper deck were also inspected.

The Suspender Boxes for the suspender cables were inspected for corrosion and broken strands from below the Upper Level using a 60’ or 85’ truck. The suspender ropes, top of deck was inspected by means of physical and visual inspection from one end to another.

COMMODORE BARRY BRIDGE

The Commodore Barry Bridge is one of four toll bridges connecting the metropolitan Philadelphia region with southern New Jersey and contains ramps to I-95. The construction involved a pair of entrance-exit ramps to access Chester Waterfront and Flower Street from I-95. Other improvements, such as deck joint replacement, concrete patching, and other safety and engineering improvements were also part of this project.

JPCL was retained to provide construction inspection services including structural steel welding, NDT and coating inspections. JPCL also provided the design review services for a longitudinal pedestrian bridge as part of this project.
