Westbrook performed Phase 1 & 2 demolition plans for the removal of the concrete deck and concrete girders. The challenge was setting a 550 TON crane on the existing bridge to remove the bridge slab and girders. WAE analyzed the existing bridge to ensure that the bridge could support the crane outriggers.

 

The contractor needed a device to catch light falling debris when lifting and removing bridge decks. WAE designed a 30’x10′ “C” platform to hang from a crane and catch light falling debris resulting from the bridge deck removal procedure. The platform can support a maximum 7,000 lb load and can be disassembled for easy shipping.

Westbrook has designed the deck removal on the existing structure. We analyzed the capacity of the structure to ensure that it could handle the excavator as it moved around on the bridge during deck removal. Future stages of the structure removal include lowering span 3 onto barges, and cutting and removing steel members with cranes.

Westbrook designed a job-specific gantry for lifting and setting prestressed girders. This method eliminated a construction joint from the bridge deck and helped the client bid the project by winning a $2 million bid bonus!
