B.Q.E #TITLECONNECTOR OF PROJECTRAMP Client: NYS Department of Transportation Budget: $47,000,000 Construction: Post-Tension Concrete Segmental Bridge, CIP Piers on Spread Footing
The replacement of the deteriorated 4-lane, 19-span, steel bridge connecting the Williamsburg Bridge to Brooklyn-Queens Expressway in the heart of New York City imposed an enormous challenge to the founder and president of Potential Engineering, PC, Mr. Sam Ghaida, P.E., of the design and construction team. As the project engineer for Daniel Frankfurt, PC, responsible for overseeing the design team of multiple specialty firms, including J. Muller International, the design and construction process was handled and executed in a professional and timely manner from start to finish. The process involved all conceivable aspects of engineering, construction stagging, Maintenance and Protection of Traffic (MPT), scheduling and coordination with local agencies and sub-consultants. The precast/post tensioned concrete box girder is one of the few bridge superstructures designed and constructed in New York City.

TEMPORARY SHORING Half of existing bridge removed an the other half shored-up during the staged construction
A collaborative endeavour with J. Muller International, a leader in such an application, provided a significant diversified experience for all parties involved. The narrow corridor with multiple street crossings and abutting road below, coupled with the congested and heavily populated neighborhood imposed a serious challenge for the maintenance and protection of traffic and construction stagging. Temporary ramps, dismantling of half of the existing bridge, shoring, underpinning, and relocation of sewer, drainage, watermains and utilities were part of the staged construction. In addition, the coordination effort is not to be underestimated. The design team included four (4) sub-consultants; and, multiple City, State and Federal agencies which reviewed, commented and approved the project prior to construction.
